Scattered to numerous showers and lightning storms are expected this afternoon, moving from west to east across central Florida. Storm motion should generally be out of the west at 5 to 10 mph, though larger boundary collisions could cause motion to be erratic at times. Primary storm threats remain gusty winds to 40 to 45 mph, occasional to frequent lightning strikes, and locally heavy rainfall. .EXCESSIVE RAINFALL IMPACT... A risk for heavy rainfall over already saturated ground could lead to localized flooding over central Florida. Quick rainfall accumulations of 1 to 3 inches are possible, potentially to 4 inches, if locations receive multiple rounds. .EXCESSIVE HEAT IMPACT... Heat and high humidity will combine to produce peak afternoon heat index values of 102 to 107 degrees, except 108 to 110 degrees for an hour or two this afternoon across portions of Okeechobee, Saint Lucie and Martin counties. A Heat Advisory will be in effect this afternoon for the aforementioned three counties. This will lead to a Moderate to High Heat Risk across all of east central Florida today. This level of heat can affect anyone without adequate precautions. It is recommended to take frequent breaks from the heat and stay hydrated, especially if spending extended periods of time outdoors during the afternoon. .DENSE FOG/SMOKE IMPACT... Patchy fog,locally dense, will be possible early this morning generally north and west of the I-4 corridor. If encountering fog on roadways, make sure to slow down and leave plenty of driving distance between your car and the one in front of you. .RIP CURRENT AND SURF IMPACT... A Moderate risk of life-threatening rip currents exists at all central Florida Atlantic beaches. Always swim near a lifeguard and never enter the water alone. .RIVER FLOOD IMPACT... The Saint Johns River at Astor is forecast to remain in Moderate Flood stage. Small additional rises are possible if locally heavy rainfall develops over the river basin. For more information, please refer to the associated Flood Warning for the Saint Johns River at Astor. .DAYS TWO THROUGH SEVEN...Sunday through Friday. Scattered showers and lightning storms are forecast on Sunday and for the upcoming week. Episodes of heavy rainfall leading to additional flooding, lightning strikes, and gusty winds will remain the primary threats. Heat and high humidity will produce peak heat indices of at least 100 to 106 degrees, again, on Sunday. Slightly lower humidity next week will allow heat indices to fall into the low 100s. A Moderate to High risk of dangerous rip currents is expected at the beaches through the extended. High astronomical tides will produce above normal water levels around the times of high tide from Sunday evening through much of next week. This may cause minor inundation of low lying properties near inlets, nearby areas along the Intracoastal Waterway, and adjacent canals. Some docks may briefly get overtopped by water. Increasing long period swells will build seas on Sunday into at least early next week promoting poor to potentially hazardous boating conditions. Flooding along the Saint Johns River, particularly at Astor, will continue Sunday through the middle of next week. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed today and tonight. $$ Sedlock
