Spring brings warmer temperatures and heavy rain. But until the ground thaws, melting snow and rain cannot be absorbed. Each cubic foot of compacted snow contains gallons of water. Once it melts, the water can result in the overflow of streams, rivers, and lakes that flood nearby homes and businesses.
Rivers and streams that froze during the winter also begin to thaw. As the ice breaks and travels downstream, ice jams can block the flow of water, creating flooding upstream. Add spring rain to the mix, and the result can be serious, widespread flooding.
