Severe Weather Record, 2026

Tornadoes, by their rating

Every tornado an office of the weather service rated in its damage survey, on the Enhanced Fujita scale, as its latest survey gives it: where and when it began, its strongest winds, the length and width of its path, the people it killed and hurt, and the warning in force where it began.

EF2, 111 to 135 mph 3

EF1, 86 to 110 mph 4

EF0, 65 to 85 mph 4

Hurricanes and tropical storms, by the category each reached

Every tropical storm and hurricane the National Hurricane Center tracked in 2026 in the Atlantic, the Gulf of America, the Caribbean and the eastern and central Pacific, by the strongest it became on the Saffir-Simpson scale; each a door to its own chronicle, and the season to its own page.

Magnitude 3 to 3.9 36

Magnitude 2.5 to 2.9 77

Volcanoes, by alert level

Every volcano in the states and territories raised above normal in 2026, or whose level changed, by its alert level, for the hazard on the ground, and its aviation colour code, for the hazard in the air, each as the Geological Survey's observatory set it in its notices. Times are in the zone each observatory keeps.

Normal, green

At rest, at its usual background.

Advisory, yellow

Unrest above its usual background, or activity much reduced after a higher level and still watched closely.

Watch, orange

Heightened or rising unrest that may lead to an eruption, or an eruption under way with limited hazards and little or no ash.

Warning, red

A hazardous eruption about to begin, under way or suspected, with much ash in the air likely.

Severe Weather Alerts

Every tornado, severe thunderstorm and flash flood warning the weather service tagged with a damage threat, at the most severe any of its messages reached, those replaced within minutes too: catastrophic, which is a tornado or flash flood emergency; destructive, for a severe thunderstorm; or considerable. Each with when it reached it, the hail, wind and detection its messages gave, and a door to its report where the record keeps it.

Flash flood emergencies 1

A severe threat to life and catastrophic damage from a flash flood.

Severe thunderstorm warnings, destructive damage threat 10

Hail of 2.75 inches or more, or wind of 80 mph or more.

Tornado warnings, considerable damage threat 3

A tornado able to do considerable damage.

Severe thunderstorm warnings, considerable damage threat 62

Hail of 1.75 inches or more, or wind of 70 mph or more.

Each is listed with its warning on the day it was issued, under Day by day.

Flash flood warnings, considerable damage threat 50

Flash flooding able to do considerable damage.

Each is listed with its warning on the day it was issued, under Day by day.

River floods, by their category

Every river point an office of the weather service warned would flood, by the category of flooding at its gauge, the most severe each reached standing: when the flooding began, its forecast crest, the highest stage reported, its flood stage and what caused it, as the office gave them.

Major flooding 4

Buildings and roads widely flooded, people moved to higher ground.

Moderate flooding 21

Some buildings and roads near the river flooded, some people moved.

Minor flooding 70

Minimal damage to property, some threat to the public.

Each is listed with its crest on the day it was first warned, under Day by day.

Space weather, by the NOAA scales

Every geomagnetic storm, solar radiation storm and radio blackout the Space Weather Prediction Center alerted or summarized, by its level on NOAA's space weather scales, from 1, minor, to 5, extreme; a radiation storm and a blackout once the Center has summarized it. Times are UTC.

Geomagnetic storms 3

G1, minor, at a K-index of 5, to G5, extreme, at 9; the K-index measures the disturbance of the Earth's magnetic field over three hours.

Radio blackouts 2

R1, minor, from an M1 solar flare, to R5, extreme, from an X20.

Warnings and watches, month by month

How many of each the weather service issued, counted once each however many times it was updated, from when the record began; every one keeps its own report after it ends.
