Across the Midwest and parts of the central United States rainfall and mild temperatures are now creating rapid melting snow and ice causing significant flooding.
This is all due to a bomb cyclone last Wednesday that brought large amounts of snow and blizzard like conditions.
Since the grounds are frozen the melted snow and ice runoff have nowhere to go.
Rivers and waterways are bursting their banks and flowing into cities and towns.
Ice jams are occuring where ice and debris build up against man-made or natural barriers as waterways attempt to flow downstream.
This is dangerous because once it breaks water will flow down rapidly.
Many rivers are expected to continue to rise over the next few days.
