Patchy dense fog is forecast early this morning. If traveling and encountering dense fog, slow down, use low-beam headlights, and leave plenty of following distance between vehicles. Fog and low clouds should burn off through mid morning. .THUNDERSTORM IMPACT... Drier air will filer into the area today, though there will still remain a threat for isolated to scattered afternoon and evening lightning storms. Primary storm impacts will be occasional lightning strikes, gusty winds 30 to 40 mph locally, and heavy downpours on already saturated ground. Movement will be generally to the east at 10 to 15 mph. .EXCESSIVE HEAT IMPACT... Heat and high humidity will combine to produce peak afternoon heat index values of 102 to 107 degrees across east central Florida today. This will lead to a Moderate Heat Risk across 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 along the Volusia coast today, with a Moderate threat for dangerous rip currents continuing south along the Brevard and Treasure coasts. In addition, a southward-flowing longshore current will exist along the beaches of Volusia County. Expect increasing rough surf along the Volusia coast as breaking waves increase to 4 to 5 feet this afternoon. .WIND AND SEA IMPACT... Northeasterly long period swells will build seas, from north to south, during the day and into tonight. Seas will gradually build to 4 to 6 feet through late this afternoon near shore, and 5 to 8 feet offshore. Boaters should Exercise Caution near shore this afternoon, with a Small Craft Advisory going into effect at 2 PM offshore north of Sebastian Inlet, extending to the offshore Treasure Coast waters at 8 PM this evening. .RIVER FLOOD IMPACT... The Saint Johns River at Astor is forecast to remain in Moderate Flood stage. The potential for small additional rises exists if locally heavy rainfall develops over the river basin. Please refer to the associated Flood Warning for the Saint Johns River at Astor for more information. .DAYS TWO THROUGH SEVEN...Monday through Saturday. Scattered, mainly afternoon and evening lightning storms, are forecast for much of the upcoming 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 next week. A Moderate to High risk of dangerous rip currents will continue at the beaches. 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 build seas through at least Monday night producing poor to hazardous boating conditions over the local Atlantic waters. 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. $$ Sedlock
