Storms Stack Up for Treasure Coast Memorial Day Weekend

TODAY: A slow build toward a stormy afternoon. Skies start partly cloudy before showers and thunderstorms develop late morning, then likely return in force through late afternoon and toward sunset. High in the upper 80s. Southeast winds 10 to 15 mph. Rain chance: 70%, the National Weather Service said in its Thursday forecast for Martin, St. Lucie and Indian River counties.

TONIGHT: Storms linger into the late evening and early morning hours before skies gradually clear after midnight. Low in the mid 70s. Southwest winds around 5 mph. Rain chance: 50%, according to NWS forecasters.

THIS WEEK: The pattern holds — and it's a wet one heading into Memorial Day weekend. Friday brings a 70% rain chance, again concentrated in the late afternoon and toward sunset, with highs in the upper 80s. Saturday offers a slight reprieve, dropping to a 60% rain chance, but showers and thunderstorms remain likely in the afternoon and evening hours. Morning windows — particularly Thursday through Saturday — offer the best opportunity to get outdoors before convection fires. The NWS forecast does not extend beyond Saturday at this time.

ON THE WATER: Southeast winds at 10 to 15 mph Thursday ease significantly by Friday and Saturday, dropping to five to 10 mph out of the southwest. That wind-down will flatten nearshore chop, making inshore runs more manageable by the weekend. Keep a hard eye on the western horizon — storm cells can build fast in this pattern. The productive fishing window is sunrise to late morning each day; once the sea breeze clocks southeast and afternoon heating peaks, lightning risk rises sharply. Work the inshore grass flats and nearshore structure early, then clear the water by noon.

ALERTS: No active NWS watches, warnings or advisories are in effect for the Treasure Coast as of this forecast. Monitor conditions through the holiday weekend — check NWS Melbourne (weather.gov/mlb) for updates before launching.
