FOX Weather meteorologists Stephen Morgan and Britta Merwin explain the importance of flood safety.
While flooding can occur at any time throughout the year, the U.S. is entering the peak of its so-called "flash flood season" as the calendar flips to June.
Flash flooding refers to floods that develop quickly, typically within three to six hours of heavy rainfall, and occur over a relatively small area. This type of flooding is different from longer-duration river flooding that can persist for days or even weeks.
According to statistics compiled by NOAA's Weather Prediction Center, 75% of flash flood reports in the U.S. occur between April 23 and Sept. 14, but there is a notable peak in flash flooding in June and July when more than one-third of the total reports occur.

Among all the types of extreme weather that claim dozens of lives each year, flooding ranks as the second deadliest in the nation, according to NOAA. Only heat kills more Americans than flooding.
The National Weather Service office in La Crosse, Wisconsin, found that flooding killed an average of 110 people annually in the U.S. over the 10-year period ending in 2022. That's significantly higher than the 30-year average of 88 people. In 2023, 31 people had already died due to flooding as of late May.

Many people underestimate the force and power of water.
More than half of all flash flood deaths happen in vehicles, according to the NWS.
"A mere 6 inches of fast-moving flood water can knock over an adult," the NWS says. "It takes just 12 inches of rushing water to carry away most cars and just 2 feet of rushing water can carry away SUVs and trucks. It is NEVER safe to drive or walk into flood waters."
