160 FNUS72 KMLB 081040 FWSMLB Spot Forecast for WBTWMA Unit 4D...FWC National Weather Service Melbourne FL 640 AM EDT Mon Jul 8 2024 Forecast is based on ignition time of 0900 EDT on July 08. If conditions become unrepresentative, contact the National Weather Service. ...HEAT ADVISORY IN EFFECT FROM 11 AM THIS MORNING TO 6 PM EDT THIS EVENING... .DISCUSSION... A Heat Advisory is in effect today. Afternoon temperatures in the mid to upper 90s and high humidity will combine to result in Heat Index values up to 112 under partly sunny skies. This level of heat can affect anyone without adequate precautions. Scattered to numerous showers and scattered lightning storms are forecast to develop into the afternoon as the east coast sea breeze moves inland and converges with the west coast sea breeze, as well as outflow from previous storms. The main hazard with slow moving showers and storms will be locally heavy rainfall (1-3" with local amounts up to 4+"). A Marginal Risk for Excessive Rainfall exists today for this reason. Additionally, isolated strong storms capable of wind gusts up to 40-50mph and occasional to frequent lightning strikes are forecast this afternoon. Rain and storm chances diminish after sunset and end by midnight. Light west-southwest winds are forecast to back east-southeast briefly this afternoon as the east coast sea breeze moves inland near or just to the east of the burn site. Dispersion values will be Poor to Fair. .REST OF TODAY... Sky/weather.........Mostly sunny (40-50 percent) then becoming mostly cloudy (65-75 percent).
