Can We Predict the Next Disaster? The Science of Wildfires, Droughts, Tornadoes and Tsunamis
From the fire-risk maps of Los Angeles to experimental tornado forecasts: what science can predict today, what AI is improving, and where nature still leaves us guessing.

| Can science predict disasters before they strike? From wildfires and droughts to tornadoes and tsunamis, new technologies are changing how we anticipate natural hazards. |
In January 2025, destructive fires swept
through neighborhoods of Los Angeles. The winds were fierce, the landscape
dangerously dry, and thousands of people had to flee. In a study published that
April, researchers showed that a machine-learning system designed to forecast
fire activity—not just dangerous fire weather—had identified elevated risk in
the region five days ahead. It did not predict the first spark or the house
that would burn. But it had seen the conditions for trouble coming.
That distinction matters. A forecast can
tell firefighters when to prepare, even if it cannot tell a family which home
will be lost. In a very different event in Missouri that same year, forecasters
used an experimental storm-prediction system to give local emergency responders
more than two hours of advance notice of a tornado threat. That was not a
routine public two-hour tornado warning; it was an example of what extra
information might eventually make possible.
These stories raise a bigger question.
Could we someday know about wildfires, droughts, tornadoes and tsunamis before
they happen? The answer is stranger—and more useful—than a simple yes or no.
Radar can see circulation hidden inside a thunderstorm. Satellites can watch
plants lose moisture or measure a tsunami moving across the ocean.
Supercomputers simulate countless possible futures. And AI can sometimes find
patterns faster than older methods.
But every disaster keeps a different kind of secret. Sometimes we can forecast the dangerous conditions, sometimes the event itself, and sometimes only what happens after it begins.
First, what do we actually mean by “predict”?
There are four very different jobs hidden
inside that word. Scientists can estimate where a disaster is more likely over
a season; forecast hazardous conditions days in advance; predict how a fire,
storm or wave will behave once it starts; or issue an urgent warning when a
threat is imminent. A system can be excellent at one job and poor at another.
Think of a medical checkup. A doctor can
estimate someone’s risk of heart disease without knowing the exact day of a
heart attack. Fire agencies can recognize a dangerously dry week without
knowing whether lightning will strike a particular tree. And meteorologists can
warn that a region is primed for violent thunderstorms long before they know
which storm, if any, will produce a tornado.
Tsunamis make this distinction particularly
clear. They are not weather events: most begin with undersea earthquakes, while
others result from landslides or volcanic activity. We cannot reliably predict
the precise time of an earthquake. We can, however, detect a dangerous
earthquake, measure the waves it generates and estimate when the tsunami could
reach distant shores.
Put simply, the important question is not
always “Will it happen?” It may be “How much time will we have once the risk
becomes clear?”
How far ahead can we see?
These are typical scales of useful guidance, not guaranteed warning times.
Wildfires
— weather and landscape danger: days to seasons;
the exact ignition often cannot be forecast.
Droughts
— regional risk: weeks to months; local outcomes
remain uncertain.
Tornadoes
— severe-storm risk: days; official tornado
warnings are often measured in minutes, with experimental guidance sometimes
earlier.
Tsunamis
— the triggering earthquake cannot be reliably
timed; once it begins, arrival forecasts range from minutes to hours depending
on distance.
How forecasts turn observations into warnings
A modern forecast begins with the imperfect
picture we have of the world right now. Weather stations measure wind and
temperature; balloons sample the air overhead; ships and buoys watch conditions
at sea. Doppler radar detects precipitation and movement inside storms.
Satellites fill in much of the space between instruments, especially over
oceans and remote landscapes.
Computers combine these scattered
observations into a single, best-available starting picture, a process
scientists call data assimilation. Think of it as reconstructing a moving scene
from thousands of photographs taken at different angles. A physics-based model
then calculates what could happen next as air rises, moisture condenses and
pressure systems move.
The problem is that the atmosphere is
chaotic. A small error in the starting picture can grow as the forecast reaches
farther ahead. That is the real meaning of the butterfly effect: not that
forecasts are pointless, but that some details—especially small, fast-moving
ones—become increasingly hard to pin down.
One answer is an ensemble forecast. Instead
of asking a model for one future, forecasters run it many times with slightly
different starting conditions. Imagine planning a picnic and seeing 40 of 50
forecasts predict heavy rain. You would probably change your plans. The spread
between those outcomes matters as much as their average: it is a window into
uncertainty, not an admission of failure.
A major change is happening inside this
process. In February 2025, the European Centre for Medium-Range Weather
Forecasts (ECMWF) put an AI forecasting system into operational use alongside
its physics-based models. In July 2025 it added a 51-member AI ensemble, and in
May 2026 both systems were upgraded. AI does not make the atmosphere
non-chaotic, but it can calculate forecasts quickly and identify patterns
learned from enormous historical datasets.
And yet no amount of speed gives a model
knowledge that the observations do not contain. The crucial advance is better
guidance about the range of possible outcomes, not a perfect countdown to
disaster.
Wildfires: the forest can be ready to burn long before it ignites
A wildfire needs a source of ignition,
something that can burn and conditions that allow flames to spread. Heat, low
humidity and strong winds make an obvious combination. Yet the same hot day may
pass quietly in one forest and turn disastrous in another. The difference can
be the moisture inside plants, the amount of dead vegetation, the slope of the
ground, the direction of the wind—and one unpredictable ignition.
This is why a fire-risk map is not a
calendar of future ignitions. In the United States, the Storm Prediction Center
issues fire-weather outlooks for the coming days, while seasonal outlooks help
agencies distribute people and equipment. Such forecasts can identify a
dangerous combination of wind, heat and dry vegetation; they cannot say when or
where somebody will drop a match.
Researchers are making the forecasts more
intelligent by studying the landscape, not only the sky. A 2025 study in
Geophysical Research Letters examined the daily spread of 196 wildfires in the
northern Rocky Mountains. Soil moisture and plant water stress proved
particularly important. Adding these measurements improved estimates of daily
fire growth compared with models using weather and fuels alone. It is a
regional result, not a universal formula, but it suggests why yesterday's
drought can matter as much as today's wind.
The next step is to forecast fire activity,
not just the weather that might feed a fire. In a 2025 Nature Communications
study, researchers combined information about vegetation, weather and likely
ignition drivers. Their model had identified elevated fire activity risk around
Los Angeles five days before the January 2025 fires. That is a result about
probabilities and regions—not a prediction of the precise ignition point.
Importantly, the study evaluated a system already producing daily forecasts,
rather than claiming scientists had invented a time machine after the event.

Once a fire begins, speed matters. Existing
satellite systems can flag heat anomalies, while aircraft and ground crews
provide detail that an orbiting sensor may miss. A newer project, FireSat,
launched its first three operational satellites in July 2026 following a
prototype mission. Its ambition is more frequent detection of smaller fires.
But the first three spacecraft do not yet amount to a fully deployed,
continuously watching global fire alarm.
Fire-spread models tackle a different
problem: where flames might travel over the next hours. They combine the mapped
fire edge, terrain, vegetation and expected winds. For emergency teams, that
can help prioritize roads, crews and evacuation zones. Yet a gusty shift in the
wind—or an unexpected new ignition—can make yesterday’s confident-looking map
obsolete.
Wildfire science is therefore building a
sequence of decisions rather than one miraculous prediction: assess seasonal
danger, prepare for a severe fire-weather day, detect new flames, update the
likely spread, and give people clear instructions while routes remain open.
Drought: the slow disaster that can arrive surprisingly fast
A drought is less spectacular than a
tornado, but it can affect far more people over a much longer period. It also
has more than one face. A farmer may have dry soil around the roots while a
city reservoir is still full; a reservoir may decline months after a failed
rainy season. Heat can make the atmosphere draw moisture from fields faster
even without a dramatic drop in rainfall.
Scientists combine rainfall records,
temperature, snowpack, rivers, groundwater, plant condition and soil moisture.
Satellites allow them to survey large areas where ground sensors are scarce.
NOAA’s Evaporative Demand Drought Index tracks how strongly the atmosphere is
demanding water from the surface—roughly speaking, how “thirsty” the air has
become. That extra pressure can be an early sign of agricultural stress.
The most unsettling case is flash drought.
Instead of developing over a season or longer, dry conditions can intensify in
a matter of weeks. A 2025 review of 122 scientific studies found that
researchers have become better at detecting these events, but predicting their
onset remains difficult. A field that looked healthy at the beginning of a
month can be struggling by the end.

| By combining satellite observations, soil moisture measurements, and AI forecasting models, researchers are improving their ability to anticipate drought conditions weeks in advance. |
A 2025 Nature Communications study offered
a promising step forward. Researchers combined deep learning with conventional
forecast models and previous observations of root-zone soil moisture—the water
plants can actually reach with their roots. The hybrid approach produced useful
forecasts up to four weeks ahead and improved flash-drought prediction in
several evaluated cases. It is not a guaranteed four-week warning for every
farm: accuracy differed across conditions and regions, and the results were assessed
on historical data.
In October 2026, a Nature study tackled the
especially difficult two-to-six-week window from another angle. Its
machine-learning system learned to correct the probabilities produced by
existing forecasts, improving the estimates of several weather extremes. The
model performed strongly in a 2025 real-time forecasting competition. The
advance is less glamorous than the promise of an AI that can “see a month
ahead,” but it is scientifically more meaningful: a better estimate of
uncertainty can help water managers and farmers act sooner.
Drought predictions matter when they change
choices: managing reservoirs, scheduling irrigation, planning crops or
protecting power supplies. The connection between rainfall, water and
agriculture is central to our recent exploration of the future of food.
Forecasting cannot manufacture water, but it can help people use the water they
have before a shortage becomes a crisis.
Tornadoes: knowing a storm is dangerous is not the same as knowing it will touch down
A tornado looks like a single spinning
column of air, but its formation depends on a complicated chain of events. Many
of the strongest tornadoes form beneath supercells: thunderstorms with
long-lived rotating updrafts. Meteorologists know the broad ingredients—warm,
moist and unstable air, together with winds that change speed or direction with
height. The stubborn question is why some storms produce tornadoes and others,
apparently similar, do not.
Days in advance, meteorologists can
forecast a region with elevated severe-storm risk. That is the role of broad
outlooks and watches. Once thunderstorms form, Doppler radar reveals areas of
rotation; debris seen by specialized radar can offer strong evidence that a
tornado is already occurring. A tornado warning is more urgent and more
localized: it means the threat is imminent or happening, not merely that
conditions are favorable.
This gap between a watch and a warning
explains why knowing that Thursday may be dangerous does not tell us which
street will face a tornado at 4:37 p.m. The finer the detail we demand, the
more the forecast depends on rapidly changing processes inside a single storm.
NOAA says the average US tornado warning
gives about 13 minutes of lead time, although actual lead times vary widely.
That is a figure about official warnings—not the maximum number of hours a
forecaster may anticipate severe weather. Warning too early without sufficient
evidence risks repeated false alarms; warning too late can leave little time to
reach shelter.

| Doppler radar helps meteorologists identify rotating storms, while experimental high-resolution forecasting systems aim to provide more time for communities to prepare for tornadoes. |
A research program called Warn-on-Forecast
is trying to narrow that gap. At NOAA’s National Severe Storms Laboratory,
rapidly updated, high-resolution computer simulations estimate how individual
thunderstorms might develop over the next few hours. They can show an
increasing risk of dangerous rotation; they cannot yet identify every future
tornado reliably or replace the judgment behind an official warning.
An example from Missouri shows the
potential. In March 2025, forecasters used Warn-on-Forecast guidance to alert
local emergency responders more than two hours before an EF3 tornado. NOAA
described the case in January 2026. It was a research demonstration and an
early briefing to responders, not a sign that every US household now receives a
two-hour public tornado warning.
That is where progress may matter most:
moving from a broad risk on the morning weather map to more specific advice for
the communities that will need it, without asking people to act on every
uncertain signal.
Tsunamis: when we cannot predict the trigger but can track the wave
A tsunami is not an unusually large
wind-driven wave. Most are generated when an undersea earthquake suddenly moves
the seafloor and displaces water above it. Underwater landslides and volcanic
activity can also start one. In deep water, the disturbance may be barely
noticeable to a ship, while still traveling across an ocean at the speed of a
passenger aircraft.
The obstacle comes first: earthquakes
themselves cannot currently be predicted with reliable dates, locations and
magnitudes. The US Geological Survey is explicit about that limit. Long-term
probabilities can show where large earthquakes are more likely over decades,
but they cannot tell a coastal town exactly when a particular fault will
rupture.
Once the earth moves, however, prediction
becomes a different problem. Seismic networks rapidly locate the quake and
estimate its magnitude. NOAA’s warning centers often issue initial messages for
US and Canadian coasts within roughly five minutes, based mainly on seismic
information. Deep-ocean DART pressure sensors and coastal sea-level gauges then
help confirm whether a tsunami has formed and how the water is moving.
Numerical models combine the best available
earthquake-source estimate with seafloor depth and coastline shape to estimate
travel times, offshore wave heights and potential flooding. For a coast across
the Pacific, that may provide hours to prepare. For a town close to the
earthquake, the first dangerous wave may arrive before an official message can
reach everyone.

| Tsunami warning systems combine earthquake measurements, deep-ocean pressure sensors, and computer simulations to estimate how dangerous waves may travel toward coastlines. |
The July 2025 Kamchatka earthquake offered
an extraordinary research opportunity. About 70 minutes after the magnitude 8.8
quake, the NASA–CNES SWOT satellite recorded an unusually wide view of the
tsunami’s sea-surface patterns. A study published in March 2026 used those
observations to infer more about where the seafloor had shifted. The work may
improve future tsunami models; it does not make satellites a reliable instant
alarm for every earthquake or nearby coast.
One practical distinction should never be
lost in the technology: if you are at the coast and feel strong or prolonged
shaking, see the sea suddenly pull back or rise unusually, or receive an
official tsunami warning, move to higher ground immediately. A local tsunami
can arrive before a phone alert. Do not wait to watch the water.
What AI changes—and what it still cannot know
AI has become the headline in almost every
forecasting breakthrough, but it is better understood as another kind of model
than as an oracle. Traditional weather systems follow equations describing the
movement of air and water. Many AI systems learn from enormous collections of
past observations and model-generated weather, discovering relationships that
help them forecast new conditions quickly. Different tools excel at different
jobs: some predict broad weather patterns, while others recognize fire hot spots
or interpret radar signals.
There is now evidence beyond controlled
laboratory examples. ECMWF runs AI forecasting systems operationally alongside
physics-based models. A Nature paper published in August 2026 described an AI
system for tropical cyclone tracks, strength and wind fields that, in the
researchers’ 2023–2025 evaluation, gained roughly a day or more of useful lead
time over leading operational baselines. Tropical cyclones are not the same as
tornadoes, but they provide a powerful test of how much additional warning better
forecasting can offer.
The most promising future may involve many
specialized systems working together. Satellites catch a suspicious hot spot.
Ground sensors confirm the conditions. A model estimates where danger might
spread. An alert reaches the people who can act. At every step, a skilled human
still has to decide what the information means and when to warn others.
AI also inherits the weaknesses of the
world it learns from. The most extreme events are rare, and high-quality
historical observations are concentrated in some countries more than others.
Models can falter when conditions fall outside their training experience. And
the fact that a prediction looks convincing on a screen does not mean it has
been tested well enough to direct an evacuation.
A 2025 review in Nature Communications
emphasized careful evaluation of AI methods for extreme events and their
responsible use in decision-making. This is a useful distinction: performing
well on archived storms is a scientific result; earning trust in a live
emergency requires reliable performance, independent testing and clear
communication about uncertainty.
The last mile of prediction is human
Suppose a forecast gives your town a 30
percent chance of damaging winds tomorrow. Should schools close? Should an
outdoor festival be canceled? What about a hospital moving vulnerable patients?
The percentage alone cannot answer. Someone has to weigh the potential harm
against the cost of taking precautions—and decide which actions are still
possible.
There are two ways to lose trust. Repeated
false alarms make warnings easier to ignore; missed threats can be disastrous.
Precision can be misleading, too. A computer map that colors one street red and
the next green may look authoritative even if the underlying data cannot
support decisions at that scale.
Access is another problem entirely. In
November 2025, the World Meteorological Organization reported that 119
countries—about 60 percent of the global total—had reported a multi-hazard
early warning system. That is progress, but the existence of a national system
does not mean every resident receives a timely, comprehensible alert or has a
safe place to go.
Even a nearly perfect forecast is useless
to someone with no mobile coverage, no reliable electricity, no accessible
evacuation route or no safe place to go. As we discussed in our look at the future of the internet,
digital services depend on very physical infrastructure. During a disaster,
that dependence becomes impossible to ignore.
For someone facing a real emergency, the
best warning answers three questions in ordinary language: What might happen
here? How certain are the forecasters? And what should I do now?
Will we ever predict every disaster?
Almost certainly not in the sense of
knowing exact times and locations for every event. Too many pieces of the
system are unresolved: the ignition of a fire, the behavior of a rapidly
evolving supercell, the future rainfall that governs drought, or the moment a
fault under the sea will rupture. Some uncertainties may shrink with new data.
Others may remain fundamental.
That does not make the work futile. The
realistic future is a connected warning chain: better monitoring of vulnerable
forests, earlier signs of water stress, higher-resolution storm guidance and
tsunami calculations that combine more measurements in real time. The tools
will be judged by what people can do with their extra minutes, hours or weeks.
Climate change raises the stakes, but it
needs careful language. A warmer climate can intensify some drought and
fire-weather risks, and higher sea levels can increase coastal inundation
during a tsunami. That does not mean every fire, tornado or tsunami can be
blamed on climate change. A climate projection describes how risks may shift
over decades; a disaster forecast concerns an event at a particular place and
time.
Picture a town using a forecast to stage
fire crews before a windstorm. Or farmers changing irrigation plans while
enough water remains. Or a hospital checking its evacuation route well before
the roads fill. None of those decisions requires perfect certainty. It requires
an honest estimate of danger that arrives soon enough to be useful.
The future of forecasting is measured in time to act
Science is steadily extending that time. We
can monitor drying soil from space, recognize storms with dangerous rotation,
detect new fires and follow tsunami waves once they exist. AI may make these
signals quicker and easier to interpret, but the warning still has to survive
the journey from a research model to an actual person.
A forecast that never changes a decision is
only information. A forecast that helps someone reach higher ground, shelter
from a tornado or move crews before a fire spreads can change the outcome—even
if it never predicts the disaster perfectly.
The most valuable breakthrough may be
neither a sharper satellite image nor a more powerful supercomputer. It may be
the hour, the day or the week they give us back.
