Build an emergency kit and make a family communications plan.
Inquire with the local officials or your lodging managers where the nearby flood-prone or high-risk areas are.
Ask about official flood warning signals and what to do when you hear them.
If in an area prone to flooding, be prepared to evacuate. Learn the area's flood evacuation routes and where to find high ground.
Elevate the furnace, water heater, and electric panel in your home if you live in an area that has a high flood risk.
Consider installing "check valves" to prevent floodwater from backing up into the drains of your home.
Use sandbags to reinforce your foundation and doors to keep floodwaters out of your home.
If feasible, construct barriers to stop floodwater from entering the building and seal walls in basements with waterproofing compounds.
Keep emergency numbers and important information handy, as well as emergency supplies, kits, and first aid items. Include water, canned food, can opener, battery-operated radio, flashlight, and protective clothing.
Be aware of streams, drainage channels, canyons, and other areas known to flood suddenly. Flash floods can occur in these areas with or without such typical warnings as rain clouds or heavy rain.
DURING A FLOOD:
Be aware that flash flooding can occur. If there is any possibility of a flash flood, move immediately to higher ground. Do not wait for instructions to move.
If possible, turn off all electrical appliances, gas, heating, and utilities at the main switches or valves.
If evacuation is necessary, secure your home where possible. Bring in outdoor furniture, move essential items to an upper floor.
Listen to local radio or television stations for up-to-date information.
Avoid getting into floodwaters or fast-moving water.
Move to higher ground whenever possible.
Be aware of dangers such as chemicals, electrical shock, animals (alligators, snakes), and submerged objects which can impale or trap you.
