How to stay safe if there is flooding

Each year, more deaths occur due to flooding than from any other thunderstorm related hazard, according to the NWS.

The Centers for Disease Control and Prevention report that over half of all flood-related drownings occur when a vehicle is driven into hazardous flood water.

If flooding is possible or expected, you should know the difference between a watch, advisory and warning according to NWS.

• Flood watch: A flood watch is issued when conditions are favorable for flooding. It does not mean flooding will occur, but it is possible.
• Flood advisory: 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.
• Flood warning: A flood warning is issued when flooding is imminent or occurring.
• Flash flood warning: 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.

The most important thing to remember in areas where there is flooding: “Turn around, don’t drown.”

It is crucial that you turn around if you see standing or flowing water. It only takes 12 inches of water to sweep your car away.

NWS advises commuters to never drive around barriers blocking flooded areas and to follow signage that advises you to turn around. It is possible for roads to collapse underwater, making them impossible for drivers to see.
