649 FXUS62 KMLB 021055 AFDMLB Area Forecast Discussion National Weather Service Melbourne FL 655 AM EDT Tue Sep 2 2025 ...New AVIATION... .KEY MESSAGES... Issued at 245 AM EDT Tue Sep 2 2025 - Breezy to gusty again today along the coast north of Cape Canaveral; a HIGH risk of life-threatening rip currents and rough surf continue for Volusia and north Brevard beaches - Poor to hazardous marine conditions forecast through this morning, mainly from Cape Canaveral northward - Elevated rain chances through Thursday, focused farther south by mid to late week; marginal risk of excessive rainfall leading to localized flooding && .PREVIOUS DISCUSSION... Issued at 245 AM EDT Tue Sep 2 2025 Current-Tonight...Former weak frontal boundary and associated weak low pressure across the south-central/south peninsula early this morning. Low-topped showers with embedded thunder continue to rotate onto the Volusia and Brevard coasts with periodic brief downpours. This trend will continue past sunrise. Very deep moisture (PWATs ~ 2.00-2.20") will continue across the area again today with SCT/NMRS showers & ISOLD/SCT lightning storms also forecast. Primary threats continue to be occasional to frequent lightning strikes in a few stronger storms and repeated heavy downpours locally that could quickly add up to 1-3" for some and aggravating any ongoing or new flooding concerns. The WPC continues to outlook much of ECFL in a low-risk Marginal threat for Excessive Rainfall. The concern here is if any "banding" is able to set up for repeated rounds of moderate to heavy rainfall. Precip chances dwindle thru the evening, but cannot rule out a few onshore-moving showers thru the night for coastal counties. Highs today in the M-U80s to around 90F, with a few L90s within reach should the sun be able to burn through clouds for a period of time. Overnight lows persistent in the L-M70s and U70s for the immediate coast. With continued gusty conditions along the Volusia and north Brevard coasts and rough surf from building swell, will go ahead and extend current RP.S through tonight. A HIGH risk of numerous, strong, life-threatening rip currents at area beaches will exist here, with a Moderate risk for south Brevard through the Treasure Coast. It is strongly advised to stay out of the rough surf. Wed-Thu...Weak high pressure will align along the Eastern Seaboard thru mid-week, as persistent onshore flow continues and the pgrad gradually relaxes. Higher rain chances will be located south of Orlando where moisture is deepest. Chances 40-50pct north of Orlando and 50-70pct southward and these numbers may be generous depending on amount of drier air filtering southward. Well south of Orlando and towards Lake Okee will still need to be monitored for heavy rainfall potential. Even with weak mid-level troughing overhead, instability will be limited with warmer mid-level (H500) temperatures (-4.5C to -5.5C). There will be occasional weak subtle shortwave impulses embedded within the WRLY flow that will aid convection. Perhaps slightly warmer each day with maxes in the U80s to L90s (esp inland). Not much change to ongoing mins. Fri-Mon...Increasing mid-level heights in the extended as weak ridging takes back hold. Still some drier air lingering northward, but a gradual return of deeper moisture does occur late in the weekend and early next week. This as the former stalled frontal boundary across south FL ventures back northward. The moisture gradient does remain fairly tight north/south and we continue to advertise scattered convective chances northward and numerous mention generally south of Orlando. Highs generally in the U80s to around 90F, though drier air northward may see max temps push into the L90s near/NW of I-4. Peak heat indices may reach 98-103F across the area during this time. && .MARINE... Issued at 245 AM EDT Tue Sep 2 2025 Today-Sat...Seas continue to build to 6-7ft at buoy 41070 with NNE-NE winds 15-20 kts. Seas may be up to 8ft still further offshore. Will extend the current Small Craft Advisory for all of the Volusia waters through 10AM/14Z this morning, with Cautionary Statements for seas building to 6ft across the offshore Brevard waters. Elsewhere winds are generally 10-15 kts with seas building 3-5 ft. Both winds/seas will gradually continue to improve later today and into mid to late week as the pgrad relaxes and seas subside. SCT/NMRS showers with ISOLD/SCT lightning storms remain forecast across the local waters today. Unsettled weather conditions continue thru mid-week as deep moisture lingers across the waters leading to above normal chances of showers and storms. && .AVIATION... (12Z TAFs) Issued at 655 AM EDT Tue Sep 2 2025 Stratus has developed across portions of the Treasure Coast and will continue to produce IFR/LIFR cigs through early this morning, before gradually breaking up near to soon after 14Z. Isolated showers may still brush along the coast this morning. Scattered to numerous showers and isolated to scattered storms will then develop into the afternoon. Hi-res guidance has not been very consistent on convective trends for today. For now have kept tempo 3hr MVFR TSRA impact groups for all TAF sites between 18-23Z. Rain chances then diminish into the evening, but isolated to scattered coastal showers will continue to be possible into tonight. Winds out of the N/NW around 5-7 knots through this morning will become N/NE into the late morning and afternoon increasing up to 10- 15 knots, with higher gusts to 20-23 knots at the coast, mainly near to north of KMLB. Winds then diminish, becoming N/NW 5 knots or less into tonight. && .PRELIMINARY POINT TEMPS/POPS...
