What is a severe thunderstorm warning?
The National Weather Service calls a thunderstorm severe when it produces hail at least one inch in diameter (about the size of a quarter), wind gusts of at least 58 mph, or a tornado. A severe thunderstorm warning is issued for the storm itself and the area in its path, usually for 30 to 60 minutes.
Some warnings carry damage tags. A "destructive" tag means gusts of 80 mph or more or hail at least 2.75 inches (baseball size) and can trigger Wireless Emergency Alerts on phones. Straight-line winds in severe storms can cause as much damage as a weak tornado, and storms can produce tornadoes with little notice.
What to do
- Move indoors to a sturdy building and stay away from windows.
- Park vehicles in a garage or under cover if hail is expected and there is time.
- Avoid driving into the storm core, where hail and downed trees are worst.
- Be ready to shelter if a tornado warning follows.
