Floods
• Are the most dangerous weather-related events in the US.
• Floods occur when water pours into a stream or river that it overflows its banks and covers the land on either side.

Predicting Floods
• Advanced warnings can help reduce flood damage and loss of life.
• Weather satellites can supply information about snow cover, so scientists can estimate how much water will rush into the river when it melts.
• Scientists check river gauges that measure water levels.

Predicting Floods
• Forecasters can predict flood heights at different points on the river with the goal to help prepare people and evacuate.
• A flood watch- means that flooding is possible.
• A flood warning- means that flooding has been reported or is about to occur. Take action!

look flooded.– Do not play in water.
• A few centimeters of water can sweep you off your feet.
– Do not try to drive on a flooded road.• Moving water can sweep a car away.• Leave the car and move to higher ground.

Other Flood Hazards
• Floods can knock down electrical poles, wires- cutting off power supplies.
• Can saturate soil, causing landslides or mudslides.
• Emergency vehicles cannot get through flooded roads.
• Flood waters can pollute water in wells and water treatment plants.– Be careful with anything that flood waters have
touched.– Boil water before drinking it.
