Severe Weather Alert - Saturday, June 20, 2026
BOCA RATON, FL — Boca Raton and the surrounding South Florida metro are getting a brief break from a formally “severe” storm, but not from storm impacts. The National Weather Service said the severe thunderstorm warning affecting northern Broward and south-central Palm Beach counties expired at 5:30 p.m. Saturday as the storm weakened. Even so, residents should expect lingering gusty winds, frequent lightning, and additional pop-up storms through the evening, with oppressive heat continuing into the weekend.
The storm that triggered the warning has weakened, but it can still produce bursts of wind strong enough to knock down small branches, blow around patio furniture, and create sudden hazards for drivers—especially on east-west roads where crosswinds can be noticeable. If you’re in Boca Raton, Deerfield Beach, Delray Beach, or nearby communities, treat any darkening skies as a cue to get indoors quickly.
Lightning can strike well away from the heaviest rain, and brief downpours can reduce visibility to near zero in minutes. Saturday’s bigger story remains the combination of unstable summer air and extreme heat.
NWS Miami’s forecast discussion highlights heat indices in the 105–112 degree range through the end of the weekend, along with increasing chances for widespread showers and thunderstorms. That means storms may redevelop after short lulls, and slow storm motion can lead to localized street flooding where heavy rain repeats over the same neighborhoods.
What to do now: move loose outdoor items inside, avoid open water and golf courses when thunder is heard, and delay outdoor workouts until storms pass. If you must drive, slow down in heavy rain and watch for ponding on roads.
