Waffle House's more than 2,000 U.S. locations span regions prone to hurricanes, tropical storms, tornadoes, and severe flooding, being concentrated in the mid-Atlantic down through the Gulf Coast and across to the Midwest.
"This is going to help fill that gap in minutes to hours lead time that's vital to know where the heaviest rain is going to hit," Ralph said. "And when and what communities are going to be affected so people in the preparedness community and water resource management community can take action to help protect people's lives and property."
"These improvements empower communities to prepare earlier and more effectively for dangerous hazards from tropical storms and hurricanes," said Michael Brennan, director of NOAA's National Hurricane Center.

While humans have assembled a lot of weather data, flash floods are too short-lived and localized to be measured comprehensively, the way the temperature or even river flows are monitored over time. That data gap means that deep learning models, which are increasingly capable of forecasting the weather, aren't able to predict flash floods.

In November 2025, a massive storm rolled across the lower Mekong River delta, dumping multiple inches of rain onto the wide, flat river plain that covers much of Cambodia. The river rose and rose. The force of the water churned up mud from the river bottom. The muddy water flowed downstream and rushed into the many farming and fishing towns that line the Mekong's banks.
LIVE RADAR: Track storms as they move through the Bay Area with Live Doppler 7 Take a look at the chart above -- we will give each storm a number with 1 being the lightest type of storm and 5 being the most severe. This way you'll know what to expect. Number 1 means a light storm with 1/2 an inch of rain or less and likely lasting a few hours or less. Number 2 is a moderate storm with 1/2 an inch to one inch of rain forecast and could include scattered power outages.
