Isolated to scattered showers and lightning storms are forecast this afternoon. An isolated stronger storm will be capable of occasional to frequent lightning strikes, wind gusts of 45-50 mph, and locally heavy rainfall. .EXCESSIVE HEAT IMPACT... Heat and high humidity will combine to produce peak afternoon heat index values of 98 to 104 degrees across east central Florida today. This will lead to a Moderate Heat Risk across much of the area. 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. .RIP CURRENT AND SURF IMPACT... A HIGH risk for life-threatening rip currents exists at all area beaches today. Entering the water is not advised. .COASTAL FLOOD IMPACT... High astronomical tides will produce above normal water levels around the times of high tide. 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. .WIND AND SEA IMPACT... Long period onshore swells will continue to promote poor to hazardous boating conditions, and seas of 6-8 feet are forecast. A Small Craft Advisory is in effect for nearshore Volusia and Brevard through 5 PM. A Small Craft Advisory continues across all offshore waters through 2 AM. Small craft should exercise caution across the nearshore Treasure Coast waters today. .RIVER FLOOD IMPACT... The Saint Johns River near Astor is forecast to remain in Moderate Flood stage (around 3.2-3.4 ft) through midweek. The potential exists for small additional rises if locally heavy rainfall develops over the river basin. .DAYS TWO THROUGH SEVEN...Tuesday through Sunday. Scattered, mainly afternoon and evening lightning storms, are forecast through much of this week. The main hazards will be locally heavy rainfall, lightning strikes, and gusty winds. Warm temperatures and high humidity will continue to produce peak heat index values up to 100 to 105 degrees through early this week. A High risk of dangerous rip currents will continue at the beaches through mid week. High astronomical tides will produce above normal water levels around the times of high tide for much of the week ahead. 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. Long period swells will continue to promote poor boating conditions over the local Atlantic waters, particularly offshore. Flooding along the Saint Johns River, particularly at Astor, will continue through the middle of next week. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed today and tonight. $$ Law
