Rain/flood safety tips

The American Red Cross' tips for heavy rain situations and flood safety:

Turn around, don’t drown! If you must drive, and you encounter a flooded roadway, turn around and go another way.
If you are caught on a flooded road and waters are rising rapidly around you, get out of the car quickly and move to higher ground.
Tune in to your local radio, NOAA radio, or news channels for the latest updates.
If your neighborhood is prone to flooding, be prepared to evacuate quickly.
Follow evacuation orders and do not attempt to return until officials say it is safe.
If power lines are down, do not step in puddles or standing water.
If the power is out, use a flashlight. Do not use any open flame as alternate lighting.

Preparing for a severe thunderstorm

The American Red Cross' tips for preparing for a severe thunderstorm:

Put together an emergency kit.
Know your community’s evacuation plan.
Create a household disaster plan and practice it.
Purchase a battery-powered or hand-crank radio
Discuss thunderstorm safety with members of your household. Be aware that a thunderstorm could produce flooding.
Pick a safe place in your home for household members to gather during a thunderstorm. This should be a place where there are no windows, skylights, or glass doors, which could be broken by strong winds or hail and cause damage or injury.
