Forecast rainfall through Monday, April 20th where areas of yellow, orange, and red show a few inches of rainfall or more.
States that will have a higher likelihood of flooding will be Alabama, Georgia, Louisiana, Mississippi, and South Carolina. Several inches of rain may fall by the time this is all said and done.
