CEDAR HILL, Mo. — Both recent and expected downpours triggered flood warnings in the St. Louis region Monday.
The Cedar Hill Fire Protection District warned any of its residents who live in flood-prone areas to "take action now" ahead of the coming storms.
"With the large amount of rain we've already received, and more rain on the way, river levels are expected to raise very quickly," the fire protection district said in a Facebook post Monday morning. "As of right now, the National Weather Service is predicting a river level of 22.5 by Wednesday morning. That's 7.5 feet above flood stage."
Big River at Byrnesville is the only projected "moderate" flooding forecast in the St. Louis region as of Monday morning, according to NOAA. The Dardenne Creek at St. Peters, Meramec River near Eureka, and Meramec River near Sullivan are all forecast for minor flooding Tuesday into Wednesday.
Heavy rain fell all morning long across the St. Louis region with the heaviest downpours setting up across southern Missouri.
The St. Louis metro received up to 1" to 3" in most neighborhoods, with St. Louis Lambert up to 1.90" as of 9 a.m. Monday morning. The rain is forecast to continue until the evening rush hour before round two other storm systems move in overnight, which are projected to be strong to severe. The main risks will be additional heavy rain, damaging wind gusts over 60 mph, and possible tornadoes.
The largest threats gradually wind down into the early morning hours Tuesday. The rain is expected to end by the afternoon.
