Has a tornado hit your house or your community? Have you received a tornado alert? NOAA scientists want to hear your story. The new Tornado Tales citizen science tool is an online survey that provides…
The Warn-on-Forecast System is a research project at the NOAA National Severe Storms Laboratory that aims to increase lead time for tornado, severe thunderstorm and flash flood warnings. Since its inception in 2009, researchers have…
New climate modeling research shows heavy rainfall events will cause more frequent and stronger flash floods by the end of the century, especially in the southwest and central United States. NOAA National Severe Storms Laboratory…
When Hurricane Ida moved inland along the Gulf Coast of Louisiana in late August 2021, a team of researchers set out to study winds associated with the damaging storm. The group, including scientists from the NOAA National Severe Storms Laboratory, captured unique datasets.
Flash flooding — the rapid rise of water in a normally dry area — is mostly related to excessive rainfall resulting in significant groundwater runoff and quick rises in waterways. NOAA National Weather Service forecasters rely on accurate quantitative precipitation estimations.
One year ago, a severe thunderstorm with extreme winds — called a derecho — tore through the Midwest United States. The event brought extensive damage, totaling an estimated $7.5 billion in damage.
Downbursts—an area of strong winds in a thunderstorm—can damage trees and buildings, disrupt air travel, and cause loss of life. Decades of work by scientists has revealed a lot of information about downbursts including certain…
Researchers at the NOAA National Severe Storms Lab are using Uncrewed Aircraft Systems (UAS) to study storm damage in rural areas .Learn about the multispectral camera on the UAS, and how it provides important imagery for researchers.
Last month, millions of people across the United States were impacted by several inches to feet of snow and the coldest temperatures in decades. Thousands lost power and water, and travel was treacherous as multi-vehicle…
Researchers are excited to announce the release of a new, extensive data product that combines a multitude of data sources to help researchers, forecasters, and weather enthusiasts.
