Safety
The strong wind gusts and hail of severe thunderstorms can damage buildings, knock down
trees, and create a hazard due to wind-blown debris.
What you can do before a storm strikes...
- Know the county you live in and the names of the major nearby cities or towns.
Severe weather warnings and statements are issued by county and reference major cities.
- Check the latest weather forecast and hazardous weather outlook.
- Watch for signs of an approaching thunderstorm.
- If a storm is approaching, keep a weather radio and/or AM/FM radio with you.
- Postpone outdoor activities if thunderstorms are imminent. This is your best way to
avoid being caught in a dangerous situation.

When thunderstorms approach...
- REMEMBER: If you can hear thunder, you are close enough to a storm to be struck by
lightning. Go to safe shelter immediately!
- Move to a sturdy building.
- If no shelter is nearby or available, get in a hard top car and keep the windows up.
- If you are boating or swimming, get out of boats and away from the water, get to land
and find shelter immediately.
- If you are indoors, unplug unnecessary appliances and only use the phone for emergencies.
