Flood Watch covers all of Brevard from Sunday morning through Monday afternoon

The National Weather Service in Melbourne has put all of Brevard County under a Flood Watch from 10 a.m. Sunday until 3 p.m. Monday, according to the watch issued at 12:41 a.m. Sunday. The watch also covers Indian River, St. Lucie and Martin counties. A Flood Watch means flooding from heavy rain is possible; it does not mean flooding is already happening.

Forecasters say a disturbance approaching from the Gulf will combine with unusually rich moisture over Central Florida to bring bands of heavy rain through Monday afternoon. The weather service expects widespread totals of 1 to 3 inches, with localized amounts of 5 inches or more that could cause flash flooding. The ground is already nearly saturated, especially along the Treasure Coast, according to the watch.

Poorly drained and urban areas could flood, and some roads may flood, the weather service says. It also warns that heavy rain could make minor tidal flooding along the coast worse. In a post Sunday morning, NWS Melbourne said the risk of excessive rainfall lasts through Tuesday, with possible flooding of roadways and low-lying areas.

The rain arrives while a High Surf Advisory and a high rip current risk are still in effect for Brevard's beaches, after a week of king tides and coastal flooding along the county's shoreline. See our latest surf and rip current story.
