| Area Forecast Discussion National Weather Service Melbourne FL 336pm EDT Wednesday Oct 8 2025 ...New KEY MESSAGES,ARINE... .KEY MESSAGES... Issued at 326pm EDT Wednesday Oct 8 2025 - Dangerous beach and marine conditions expected to worsen again going into the weekend. Coastal flooding, life-threatening rip currents, and rough surf with minor to moderate beach erosion especially near times of high tide are expected. - Rain chances increase Thursday and Friday. A Marginal Risk for excessive rainfall exists along the coast each day where soils are saturated from recent rainfall. - A cold front passes central Florida late week, bringing a more fall-like airmass late this weekend and into early next week. Issued at 326pm EDT Wednesday Oct 8 2025 Rest of Today - Tonight A band of dry air with PWATs (Precipitable Waters) as low as 1" is sliding across Central Florida, between higher moisture to the north from an approaching weakening front, and another band of higher moisture to the south associated with a weak surface trough extending from the local Atlantic waters towards the Straits of Florida and Caribbean, both bringing PWATs (Precipitable Waters) to around 1.6" across the far north and south. Other than scattered sprinkles and light showers supported by low-level moisture from the more muted onshore flow today, mainly across the southern counties at this point, relatively quiet conditions are present across East Central Florida, other than the continued hazardous beach conditions. Rip Current Statements and Coastal Flood Advisories remain in effect for our coast, and entering the surf is not advised. Generally quiet conditions are expected to continue through the night, then towards morning, rain chances and winds begin to increase as the front nears. Thursday-Saturday...Beach and marine conditions deteriorate again, especially Friday and Saturday. A weakening cool front approaches Florida from the north, causing an ENE pressure gradient across the area between the approaching front and a weak surface trough/broad area low pressure extending from the Florida east coast into the Caribbean to tighten once again, resuming brisk onshore flow. Still a little uncertainty how far into Central Florida, if at all, this front will make it Thursday or Friday. Then Saturday, a low pressure system is forecast to develop along the boundary offshore response to a mid-upper level trough that quickly digs down the southeast and over Florida. There is also some uncertainty in the exact timing and location of the low's development. Given the deep synoptic forcing this low is expected to remain extra tropical, but that won't lessen the impacts to the beaches and local Atlantic waters as the pressure gradient further tightens and onshore winds further increase the same time as we see the highest astronomical tides of this set. Water levels along the coast and Intracoastal waters waterways are forecast to reach 2-3 ft above normal tides, which is about 0.5-1 ft above the levels we've seen the last several days. A Coastal Flood Advisory remains in effect through Thursday evening, as water levels are currently forecast to come in near to slightly above today's levels, and a Coastal Flood Watch has been issued for Thursday night through at least Saturday night for the increasing levels. There is potential for these higher water levels to arrive as early as Thursday. Conditions at the beaches will remain dangerous, including numerous life- threatening rip currents, rough surf, and minor to moderate erosion. Northeasterly winds will become breezy to windy, especially along the immediate Volusia coast Friday and Saturday where there is potential for winds to around 25 mph with gusts to around 35 mph. Along the Brevard coast and across the inland northern counties, winds could reach to around 20 mph with gusts to around 30 mph. The band of dry air across Central Florida is pinched off by increasing moisture from the north (approaching front) and south (band of higher moisture associated with the weak surface trough), which combined with the increasing onshore flow will return above normal rain chances and potential for heavy rainfall leading to flooding, especially along the coast due to coastal convergence Thursday and Friday. Coastal locations that receive repeated rounds or training of heavy rainfall are likely to receive 1-2" of rainfall, with locally high amounts over 4" leading to flooding possible. Areas outside of these bands/targeted spots will see lower rainfall amounts. Locations that have received significant rainfall the last couple weeks, and low- lying coastal/Intracoastal areas, will be especially sensitive to flooding. Isolated thunderstorms capable of occasional cloud to ground lightning and gusty winds will also be possible, but the primary threat will be heavy rainfall. Once the low develops it is forecast to quickly depart to the north, filtering much drier air over Florida, knocking down rain chances and delivering a Florida version of fall by Saturday. Sunday-Tuesday (Modified Previous Discussion)...A dry post-frontal airmass spreads central Florida on Sunday with no mentionable rain chances and more moderate winds forecast through early next week. A taste of fall is welcomed with lower humidity and afternoon high temperatures in the low to mid 80s. Morning low temperatures range from the low to mid 60s across the interior and the mid to upper 60s along the coast. While the weather becomes more pleasant, long period swells and high astronomical tides will cause dangerous beach and marine conditions including rip currents, rough surf, coastal flooding, beach erosion, and high seas to continue into Sunday. Some gradual improvement is expected going into the work week, but some impacts will be very slow to shake off. Marine Issued at 326pm EDT Wednesday Oct 8 2025 (Modified Previous Discussion) Seas have finally subsided a bit, but this will be short-lived as a cold front approaching from the north Thursday and Friday causes conditions to deteriorate again, and non-tropical low pressure system developing offshore Saturday further worsens conditions. East-northeast winds around 15 kts today increase to 20-25 kts across the Volusia waters, and to around 20 kts across the Space Coast waters Thursday and Friday. A push of 20-25 kt northerly winds spread the local waters behind the front Friday night into Saturday while lower wind speeds 15-20 kts may be maintained along the Treasure Coast. Seas begin building southward across the waters Thursday night becoming 5-8 ft nearshore and 6-9 ft offshore on Friday. Seas further peak 8-11 ft offshore Saturday night, gradually subsiding into early next week. Isolated to scattered onshore-moving showers are forecast today becoming unsettled with increasing rain chances tonight into late week.
