West Palm Beach, FLA. (WPEC) — South Florida is facing another round of heavy rainfall today, especially south of Alligator Alley, as a deep upper-level trough—a large-scale dip in the jet stream—continues to influence the region’s weather. This trough is extending down the Eastern Seaboard and helping to maintain a stationary surface boundary across central Florida, which is funneling moisture from the Gulf of America into the area.
Numerous showers and thunderstorms developing each afternoon, driven by daytime heating, sea breezes, and outflow boundaries—localized wind shifts caused by nearby storms. The strongest storms are expected over interior South Florida, where these boundaries converge. Hazards include gusty winds (30–50 mph) and heavy downpours.
Rainfall totals today are expected to range from 1 to 2 inches, with isolated areas possibly receiving 2 to 4 inches. In a worst-case scenario, some spots could see 4 to 6 inches in a short period, which could lead to localized flooding, particularly in urban areas with poor drainage. While a Flood Watch has not yet been issued, one may be needed for Sunday or Monday, depending on how the pattern evolves…
