Flooding will be an issue across the St. Louis metropolitan area as heavy rainfall continues to drench the region. Overall average rainfall for the entire area will be between four and eight inches, with some points west and southwest of St. Louis on into the Ozarks seeing a chance at 10 inches of rain. The rain will continue to be heavy at times well into the evening. There may be a bit of an easing of the rainfall Sunday as the main system pulls itself together for a final push north. Heavy rain will return Sunday night and on into Monday, with several more inches possible at that time. Water rescue crews with the Monarch Fire Protection District had to retrieve a man from a tree late Saturday night after the man was forced to take refuge from floodwaters. One of the areas with the most significant problems Saturday was in Brentwood near Maplewood. West County EMS and Fire reported having to rescue 10 people from floodwaters. Fire and rescue crews pulled people from their cars, homes, and businesses due to the flash flooding. Residents said this was not the way they intended to spend their holiday weekend. Deer Creek near Tilles Park flooded out of its banks at the Rock Hill/Ladue line, as seen in phone video sent in by Fox 2 meteorologist Angela Hutti. A spokesman for the Metropolitan Sewer District said the agency was prepared to handle the heavy downpour.
