FLASH FLOODS

WHAT ARE FLASH FLOODS

• Flash floods are short term events
• They are large amounts of water that
• drown an area, destroy homes,
• and can kill

WHY DO FLASH FLOODS HAPPEN

• Main causes of flash floods are:
• Levee failure
• Dams breaking
• Heavy Rain
• Ice Jam or Snow melt

OTHER REASONS FOR OCCURRENCE

• If water level rises to the overflowing
• point on high ground, it can weaken
• the soil and then cause mud slides.
• Which then leads to more deaths and
• property destruction.

WARNING SIGNS

• The obvious factor, heavy rain
• Also if there are back to back storms
• Small streams and creeks begin to rise
• The water becomes muddy

MAJOR WARNING SIGN

• If a normally small creek, no
• more than six inches deep, starts
• to rise and meets 10 ft. in one hour,
• a flash flood will occur

RESULTS OF A FLASH FLOOD

• Most fatalities of flash floods happen
• in a vehicle. What some people don't realize
• is that 2 ft. of rushing water can float a car.
• Severe damage and flooding.
• An average of 99 people die a year to flash floods
