MIAMI, Florida – The National Weather Service in Miami forecasts scattered to numerous showers and thunderstorms across South Florida on Thursday, October 1, 2026, with the highest chances over the Atlantic coast and far southern areas. Rain probabilities reach 87–91% from Fort Lauderdale through Miami, Homestead, and Flamingo. NWS Miami South Florida Doppler Radar Moist flow continues to support deep tropical moisture over the region, favoring repeated rounds of storms with daytime heating and the Atlantic sea breeze. The best additional coverage is expected this afternoon into early evening, especially along the east coast metro and southern tip. Primary hazards include locally heavy downpours, frequent lightning, and gusty winds. A few severe thunderstorms cannot be ruled out. Urban and poor-drainage flooding remains a concern where storms train or move slowly, particularly in areas that have seen recent rainfall. Extra caution is advised on wet roadways. Mean rainfall is generally about a half inch to 1 inch in many locations, though slow-moving storms and efficient downpours can produce higher localized totals in a short time. Official guidance shows the highest probabilities along the east coast from West Palm Beach southward through Homestead and Flamingo.
