Sudden Danger: Forecasting Flash Floods

While perhaps not as feared as tornadoes, hail, or lightning, flash floods are one of the deadliest weather hazards in the United States. Learn More

New Mobile Radar

Three cutting-edge mobile weather radars unveiled by NOAA National Severe Storms Laboratory (NSSL) Monday will allow NOAA researchers to deploy research-grade technology to the front lines of tornadoes, wildfires, hail storms, flash flooding and severe wind events, significantly expanding critical insight into hazardous weather threats in real time. Learn More

Swept away

Flash floods are a worldwide hazard, and are the number one hazardous weather related killer in the United States. NSSL researchers include hydrologists and hydrometeorologists to address the complicated problem of forecasting and warning for these events. Learn more →

Revolutionizing Hail Forecasts…

…one falling stone at a time. A new high-speed camera captures hail in free fall to improve public safety. Learn more →

Warn-on-Forecast: A Weather Forecasting Moonshot

The Warn-on-Forecast System is a revolutionary approach to forecasting severe weather and tornadoes that could lead to a historic leap in warning lead times. Learn more →

A Clear Vision

For more than 30 years, the nation’s weather forecasting has relied heavily on the NEXRAD radar network, the global gold standard in weather radar. But now the system is reaching the end of its designed lifespan. Phased array radar stands as a potential paradigm-shift solution for the future of weather radar in the United States. Read more →

Citizen Science: Tell your TORNADO TALE!

Has a tornado hit your community? Have you received a tornado alert? NOAA scientists want to hear your story! The Tornado Tales citizen science tool provides a way for people to anonymously report their tornado experiences. Watch the video and learn more! :: Tell your tornado tale!

Step into the wild world of weather!

What is a wall cloud? What's the difference between a watch and a warning? Is it ever “too cold to snow”? Learn about tornadoes, hail, lightning, floods, and more at Severe Weather 101, and check out our new Twisters FAQ!

SUDDEN DANGER: The Science and Stakes of Flash Flood Forecasting

July 1, 2026

Flash flooding is the deadliest hazard associated with severe thunderstorms and are one of the hardest to predict. NSSL is hard at work developing new tools and technologies to equip forecasters to issue better, faster warnings and keep you safe.

Weather Safety at the World Cup: New NOAA Weather Tool Helping Keep Fans Safe

June 24, 2026

From the biggest stages in the world to the smallest local gatherings and everything in between, weather safety depends on one thing: time. WoFS is giving that time back to the forecasters and decision makers who need it most.

LIFT Project Captures Elusive Near-Ground Wind Data on Nebraska Tornadoes

May 26, 2026

Researchers from NSSL's LIFT project captured a complete LiDAR data set on near-ground winds for a strong tornado in SE Nebraska.

SCIENCE IN THE DAMAGE PATH

May 19, 2026

On Thursday, April 23, 2026, a violent tornado tore through Enid, Okla. As the storm dissipated and the skies cleared, NSSL jumped into action.

CLOSE ENCOUNTERS: LIFT campaign seeks unprecedented tornado and hail data

April 29, 2026

NSSL's LIFT project seeks to better understand the structure of tornadoes and other severe weather hazards and how they form by gathering vital, yet difficult-to-obtain observations in close proximity to tornadoes and extreme hail.

Storm ready: NOAA’s new mobile radar fleet bridges gap between research and weather safety

March 30, 2026

NSSL's three cutting-edge mobile weather radars will allow NOAA researchers to deploy research-grade technology to the front lines of tornadoes, wildfires, hail storms, flash flooding and severe wind events, significantly expanding critical insight into hazardous weather threats in real time.
