West Palm Beach, Fla (CBS12) — A blustery, wet and hazardous stretch of weather is expected across the Treasure Coast and Palm Beaches, with the greatest concerns today and tomorrow.
Persistent northeast winds will push showers onshore, while high tides and rough surf raise the risk of coastal flooding.
Windy conditions and occasional coastal showers are expected to linger later in the week.
