More than 30,000 people were out of power in the area due to the storm. Cars were also flipped and numerous trees, power lines, and traffic signals were downed.
Damage from the storms was estimated at $40,000.

THE STORM PREDICTION CENTER HAS ISSUED A SEVERE THUNDERSTORM WATCH FOR ALL SOUTH FLORIDA EFFECTIVE UNTIL 8 PM EDT. THE COMBINATION OF NORTHWESTERLY FLOW ALOFT A WEAK BOUNDARY OVER NORTH CENTRAL FLORIDA AND THE DEVELOPMENT OF SEA BREEZES WILL LEAD TO THE FORMATION OF SHOWERS AND THUNDERSTORMS AREA WIDE. THE STRONGEST STORMS ARE FORECAST FOR THE CENTRAL AND EASTERN SECTIONS OF SOUTH FLORIDA WHERE THE WESTERLY WINDS ARE FORECAST TO MEET WITH THE EAST COAST SEA BREEZE. THE MAIN THREATS FOR THIS AFTERNOON ARE DAMAGING WINDS UP TO 60 MPH AND HAIL UP TO ONE INCH IN DIAMETER. A FEW THUNDERSTORMS COULD GET TRAPPED NEAR THE SEA BREEZE AND MOVE SLOWLY FOR A PERIOD OF TIME BEFORE MOVING SOUTHEASTWARD. THIS COULD LEAD TO LOCALIZED FLASH FLOODING. THE LATEST MODEL RUN OF THE WRF AND RUC DEVELOP CLUSTERS OF THUNDERSTORMS OVER CENTRAL FLORIDA THAT MOVE SOUTHEASTWARD DUE TO THE NORTHWESTERLY FLOW ALOFT. THE CONVECTION SHOULD START TO SUBSIDE SHORTLY AFTER SUNSET. THE OVERALL WEATHER PATTERN CONTINUES TO BE VERY SIMILAR FOR THURSDAY AND FRIDAY WITH THE TROUGH OF LOW PRESSURE MOVING INTO THE WESTERN ATLANTIC BETWEEN NOW AND FRIDAY. BETWEEN FRIDAY AND TUESDAY A RIDGE OF HIGH PRESSURE IS FORECAST TO BUILD OVER THE CENTRAL US AND MOVE SLOWLY OVER THE SE US. THE WEATHER PATTERN DURING THIS PERIOD WILL BE DOMINATED BY THE INTERACTION OF SEA BREEZES WHICH WILL LEAD TO THE FORMATION OF SHOWERS AND THUNDERSTORMS EACH DAY. AVIATION... SCATTERED TO NUMEROUS AFTERNOON SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP THROUGH THE LATE AFTERNOON AND EARLY EVENING ACROSS SOUTH FLORIDA. THE MAIN IMPACTS FROM THESE STORMS OUTSIDE OF REDUCED VSBYS/CIGS WILL BE DAMAGING WIND GUSTS UP TO SEVERE LEVELS. AT THIS TIME...IT APPEARS THE BULK OF THE HEAVIER STORMS WILL REMAIN JUST INLAND OF THE PALM BEACH TERMINALS. THIS ACTIVITY SHOULD TREND DOWN THROUGH THE LATE EVENING HOURS PAST SUNSET. MARINE... ASIDE FROM A FEW PERIODIC SHOWERS AND THUNDERSTORMS, RATHER TRANQUIL MARINE CONDITIONS ARE EXPECTED THROUGH AT LEAST FRIDAY. SUSTAINED WINDS ARE EXPECTED TO REMAIN 15 KNOTS OR LESS WITH SEAS NO HIGHER THAN 3 FEET. FIRE WEATHER...
