Severe Weather Alerts
A thunderstorm is considered severe if it produces hail at least 1 inch in diameter or has wind gusts of at least 58 miles per hour (50 knots). Every thunderstorm produces lightning, which kills more people, some years, than tornadoes or hurricanes. Heavy rain from thunderstorms can cause flash flooding. High winds can damage homes and blow down trees and utility poles, causing widespread power outages. Every year people are killed or seriously injured because they didn’t hear or chose to ignore severe thunderstorms warnings.
- Listen to the local news or a NOAA Weather Radio for emergency updates. Watch for signs of a storm- darkening skies, lightning flashes, or increasing wind.
- If you can hear thunder, you are close enough to be in danger from lightning. If thunder roars, go indoors! Don’t wait for rain. Lightning can strike out of a clear blue sky.
- Avoid electrical equipment and corded telephones. Cordless phones, cell phones and other wireless handheld devices are safe to use.
- Keep away from windows.
- If you are driving, try to safely exit the roadway and park. Stay in the vehicle and turn on the emergency flashers until the heavy rain ends.
- If you are outside and cannot reach a safe building- avoid high ground, water, tall, isolated trees, and metal objects (fences, bleachers). Picnic shelters, dugouts, and sheds are NOT safe.
