Water Entered Homes in the West Palm Beach Area Sunday Night: 9 to 12 Inches of Rain, Streets Impassable, and a Flash Flood Warning Extended to 11:15 P.M.

Florida's flood day ended with its worst water in Palm Beach County. The National Weather Service in Miami extended the flash flood warning for northeastern Palm Beach County until 11:15 p.m. Sunday, after an 8:52 p.m. warning update reported that the public had reported flash flooding in communities near Military Trail, with water entering homes. Roads and streets near Okeechobee Road and Military Trail were reported impassable, and between 9 and 12 inches of rain had fallen in the warning area. The Weather Service called it life-threatening flash flooding, already occurring, with another half-inch to an inch of rain possible.

The escalation was fast. The warning was first issued at 5:23 p.m. with 2.5 to 3.5 inches down; by 8:03 p.m. the Weather Service reported several unofficial sites in the warning area at 10 to 12 inches for the day, most of it in the last three hours, with many streets impassable in the Florida Turnpike, Military Trail and I-95 corridor between Okeechobee Boulevard and the Bee Line Highway. At 8:35 p.m. the heaviest rain was shifting northwest over the Grassy Waters Preserve and western sections of Palm Beach Gardens. The warning area includes West Palm Beach, Palm Beach Gardens, Riviera Beach, North Palm Beach, Lake Park, Haverhill and Mangonia Park.

Palm Beach, Broward and Miami-Dade counties remain under the flood watch the Weather Service issued earlier Sunday, running through Monday afternoon — the same statewide system that put Orlando's own counties under a Melbourne-office flood watch Sunday night. The warning's advice is the standing one, and Sunday night in Palm Beach County it was not abstract: turn around at flooded roads, and do not venture outside until the waters recede.
