Office of Emergency Management Severe Weather Preparations For:
Brief, heavy rainfall
What Should I Do?
Remove all outdoor items which can be tossed by strong wind gusts and secure them.
Be prepared to stay in place if dangerous flooding occurs in your area.
Communicate with your family ahead of time about what to do if you cannot get home at a normal time due to the heavy rain.
Have a plan to shelter-in-place at your home, school or business.
If you are participating in outdoor activities, be prepared to shelter in a sturdy structure if you hear thunder. Wait until 30 minutes after the last thunder clap before going back outside. When Thunder Roars, Go Indoors.
If a TORNADO WARNING is issued for your area, seek shelter immediately in an interior room on the lowest floor possible.
If a FLASH FLOOD WARNING is issued for your area, seek higher ground and avoid travel until the warning expires.
Be aware of changing conditions and turn on NOAA Weather Alert radios.
