WEST PALM BEACH, Fla. — Another hot and humid day is expected across the Palm Beaches, Treasure Coast and the Lake Okeechobee region on Sunday, with afternoon temperatures climbing into the lower 90s and heat index values reaching low 100’s.
After a few passing storms and rain showers this morning, scattered thunderstorms are expected to develop during the afternoon as the Atlantic sea breeze moves inland. The greatest chance for storms will be across western Palm Beach County, Okeechobee County, and inland portions of Martin, St. Lucie and Indian River counties where sea breeze boundaries collide.
Communities closer to the coast like West Palm Beach, Jupiter, Stuart, Fort Pierce and Vero Beach will have lower rain chances, but an isolated thunderstorm remains possible late this afternoon…
