Overview
- Forecasters say showers and thunderstorms will be most widespread Sunday afternoon into early evening, with the highest risk for heavy rain roughly between 2 p.m. and 6 p.m.
- Local meteorologists estimate about a 60% chance of widespread rain for the Palm Beaches and Treasure Coast and expect 0.25 to 1.5 inches of rain in most places with pockets of heavier downpours.
- Storms could produce torrential rain, frequent lightning, wind gusts up to 30–45 mph, and localized street flooding in poor drainage areas, so people with outdoor plans should seek shelter during storms.
- The day will be hot and humid, with highs in the low to mid-90s and heat-index values near 100–105 degrees before storms form, and activity is expected to weaken after sunset with quieter conditions overnight after about 7 p.m.
- Meteorologists link the renewed storms to a regional surge of tropical moisture tracked since mid-July and say another active day is likely Monday before a midweek shift returns heavier storms toward inland areas.
