Important information you should know before, during and after a flood from the National Weather Service.
Remember the most important rule: TURN AROUND, DON'T DROWN! Water can be deeper than it appears and it can also hide many hazards such as sharp objects. Vehicles caught in swiftly moving water can be swept away in a matter of seconds. NWS says that 12 inches of water can float a car or small SUV and 18 inches of water can carry away large vehicles.
Flash Flood Warning vs. Watch
Here's the difference between a Flood Warning and Flood Watch:
Flash Flood Warning: Take Action! A Flash Flood Warning is issued when a flash flood is imminent or occurring. If you are in a flood prone area move immediately to high ground. A flash flood is a sudden violent flood that can take from minutes to hours to develop. It is even possible to experience a flash flood in areas not immediately receiving rain.
Flood Warning: Take Action! A Flood Warning is issued when the hazardous weather event is imminent or already happening. A Flood Warning is issued when flooding is imminent or occurring.
Flood Watch: Be Prepared:A Flood Watch is issued when conditions are favorable for a specific hazardous weather event to occur. A Flood Watch is issued when conditions are favorable for flooding. It does not mean flooding will occur, but it is possible.
Flood Advisory: Be Aware: An Flood Advisory is issued when a specific weather event that is forecast to occur may become a nuisance. A Flood Advisory is issued when flooding is not expected to be bad enough to issue a warning. However, it may cause significant inconvenience, and if caution is not exercised, it could lead to situations that may threaten life and/or property.
Before A Flood
Create a Communications Plan - It is important to be able to communicate with your family and friends in the event of a disaster. Whether it is having a specific person identified to contact for status updates or a safe location to meet up with family members, having a plan in place will give you peace of mind if disaster does strike.
Assemble an Emergency Kit - It is good practice to have enough food, water and medicine on hand at all times to last you at least 3 days in the case of an emergency. Water service may be interrupted or unsafe to drink and food requiring little cooking and no refrigeration may be needed if electric power is interrupted. You should also have batteries, blankets, flashlights, first aid kit, rubber boots, rubber gloves, and a NOAA Weather Radio or other battery operated radio easily available.
Know Your Risk - Is your home, business or school in a floodplain? Where is water likely to collect on the roadways you most often travel? What is the fastest way to get to higher ground? Knowing the answers to these questions ahead of time can save your life.

Prepare Your Home
- If you have access to sandbags or other materials, use them to protect your home from flood waters if you have sufficient time to do so. Filling sandbags can take more time than you may think.
- Have a professional install check-valves in plumbing to prevent flood waters from backing up into the drains of your home. Make sure your sump pump is working and consider having a backup. Make sure your electric circuit breakers, or fuses, are clearly marked for each area of your home.
- Since standard homeowners insurance doesn't cover flooding, ensure coverage by contacting your insurance company or agent to purchase flood insurance. This must be done before there is even a threat of flooding as insurance companies stop issuing policies if there is a threat of flooding. (i.e. an approaching hurricane). Many flood insurance policies take at least 30 days to go into effect so even if you can buy it as a storm is approaching, it may not protect your investment.
Prepare your Family/Pets - You may be evacuated, so pack in advance. Don't wait until the last moment to gather the essentials for yourself, your family and/or your pets.
Charge Your Essential Electronics - Make sure your cell phone and portable radios are all charged in case you lose power or need to evacuate. Also make sure you have back-up batteries on hand.
Leave - If it is likely your home will flood, don't wait to be ordered to leave; evacuate yourself! Make alternative plans for a place to stay. If you have pets, take them with you or make arrangements to board them at a facility well away from the flooding danger.
During a Flood
Stay Informed - Monitor local radio and television (including NOAA Weather Radio), internet and social media for information and updates.
Get to Higher Ground - Get out of areas subject to flooding and get to higher ground immediately.
Obey Evacuation Orders - If told to evacuate, do so immediately. Be sure to lock your home as you leave. If you have time, disconnect utilities and appliances.
Practice Electrical Safety - Don't go into a basement, or any room, if water covers the electrical outlets or if cords are submerged. If you see sparks or hear buzzing, crackling, snapping or popping noises --get out! Stay out of water that may have electricity in it!
Avoid Flood Waters - Do not walk through flood waters. It only takes six inches of moving water to knock you off your feet. If you are trapped by moving water, move to the highest possible point and call 911 for help.
After a Flood
Stay Informed - Stay tuned to your local news for updated information on road conditions. Ensure water is safe to drink, cook or clean with after a flood. Oftentimes a boil water order is put in place following a flood. Check with utility companies to find out when electricity or gas services may be restored. Carbon monoxide poisoning is one of the leading causes of death after storms when areas are dealing with power outages. Never use a portable generator inside your home or garage. Information from the CDC on generator safety can be found here.
Avoid Flood Waters - Standing water hides many dangers including toxins and chemicals. There may be debris under the water and the road surface may have been compromised. If it is likely your home will flood, don't wait to be ordered to leave; evacuate yourself! Make alternative plans for a place to stay. If you have pets, take them with you or make arrangements to board them at a facility well away from the flooding danger.
Avoid Disaster Areas - Do not visit disaster areas! Your presence may hamper rescue and other emergency operations.
Heed Road Closed and Cautionary Signs - Road closure and other cautionary signs are put in place for your safety. Pay attention to them!
Wait for the "All Clear" - Do not enter a flood damaged home or building until you're given the all clear by authorities. If you choose to enter a flood damaged building, be extremely careful. Water can compromise the structural integrity and its foundation. Make sure the electrical system has been turned off, otherwise contact the power company or a qualified electrician. Contact your insurance agent as soon as possible to discuss the damage done to your property. If you have a home generator, be sure to follow proper safety procedures for use.
Contact Your Family and Loved Ones - Let your family and close friends know that you’re okay so they can help spread the word.
