A flood is when there is too much precipitation or overflowing waters. The water starts to go on land because there is no room for it anywhere else.

How Does a Flood Form?

A flood forms when too much rain falls. It can also be formed by overflowing lakes, dams, or rivers. The water has no where to go, so it stays on land. I bet you have also heard of something called a flash flood before. A flash flood is the same thing as a flood, but it happens much faster and unexpectedly. There is normally Cumulonimbus clouds during a flood. Floods occur in a low pressure system. In a low pressure system it is cloudy and not very sunny.

Historical Examples of a Flood

The 1993 Missouri River flood was a horrific flood that happened not too long ago. 50 people died from it and it costed $15 billion in damage. It caused tons of people to evacuate. The flood occurred in North Dakota, South Dakota, Wisconsin, Illinois, Nebraska, Kansas, Iowa, and Missouri 75 towns were completely destroyed.

On May 31st 1889, a dam broke and flooded Pennsylvania killing more than 2,200 people. It caused $17 million dollars in damage. There are no records of any injuries. The dam was 900 by 72 feet. You can just imagine how much water was there and why it was a big deal especially in the late 1800's. They had no way to prepare for it.

Floods are always very serious.

Preparing for Floods

Today we have the technology to prepare for floods. Floods are impossible to prevent, but we can get ready for them. If you watch the weather channel, they show the weather radar to see where rain is falling. If you listen to the radio they will also give warnings and watches for floods and many other natural disasters.

One thing you shouldn't do when there is a flood, is to drive or walk outside. Only drive if you are evacuating the area. You could get into serious trouble if waters get too deep. To have your house ready for a flood at any time, you would need to have an elevated home. That means that it comes up off of the ground. Your house will be less likely for flood waters to fill inside, unless flood waters get too high. Always be prepared because you never know when a flood or a flash flood could come
