Marine Weather and Tide Forecast for Windsor, FL

DISCUSSION
Issued at 300 PM EDT Thu Oct 8 2026

Currently-Tonight...A Flood Watch continues across all of east central Florida through late this evening. Daytime heating near to south of a stalled front across the area has increased instability, with mesoscale analysis showing MLCAPE up to 1000-1500 J/kg across much of the region. Showers and storms across SW Florida are moving slowly northeast and should increase in coverage, especially with boundary interactions with the inland moving east coast sea breeze across the southern interior. Numerous showers and storms should result and also push slowly northeast and offshore into this evening. Deep moisture, with record PW values for the day around 2.4- 2.5" and slower motion of developing convection will lead to quick rainfall accumulations of 2-4", with a low potential for localized totals of 5-7". This may lead to flash flooding in some spots, especially across those areas where heavy rainfall has already occurred recently. A Slight Risk (Level 2 of 4) for excessive rainfall exists across much of the area.

Convection should diminish or shift offshore into late evening, with some lingering rain chances (up to 20-40%) overnight, mainly north and east of Orlando as an onshore flow persists north of the front.
Humid conditions will persist, with lows tonight in the low to mid 70s.

Friday-Sunday...Hurricane Isaias will lift northward across the central Gulf, making landfall across the northern Gulf coast into Friday night. This will shift the stalled front across the area gradually northward through late week and into the weekend, with E/SE flow Friday becoming more gusty into Saturday as it becomes S/SE. While overall PW values do decrease a tad as front lifts north, they remain anomalously high (around 2.0-2.3"). This will continue scattered to numerous showers and storms each day from late week through the weekend, with greatest coverage during the afternoon and evening hours. Highest rain chances will be near to north of Orlando on Friday (around 60-80%) and drop to 30-50% across central and southern portions of the area tomorrow. As deeper moisture continues to build in the southerly flow, PoPs rise to 80% Saturday and then fall slightly to 50-70% on Sunday.
A few storms could be strong each day, producing wind gusts near 45 mph. An increase in storm motion and initial drop in PW values on Friday should lower the risk for locally heavy rainfall, but as moisture again rises into Saturday, a Marginal Risk (Level 1 of 4) for excessive rainfall returns across the area.

As front lifts north and southerly flow increases, temperatures will rise into the upper 80s/near 90 degrees for some spots through the weekend. Humid conditions will lead to peak heat index values in the 100-105F range each afternoon. Warm and muggy conditions continue overnight, with lows in the 70s.

Monday-Thursday...(Modified Previous Discussion) The trough containing the remnants of Isaias moves off of the eastern U.S.
coast early next week. Meanwhile, high pressure strengthens and stacks vertically over the northern Gulf Coast, moving eastward through the period. A weak front associated with the trough will push southward across the area Monday, which will finally lower rain chances across the area and lead to less humid conditions.
PoPs lower to 20-30% Monday as front moves through, with dry conditions then forecast for Tuesday through Thursday. Northerly flow prevails through mid-week, as the ridge moves eastward, veering onshore late in the period. High temperatures overall remain in the mid to upper 80s. However, much less humid conditions Tuesday and Wednesday will limit heat indices to the lower to mid-90s. Overnight lows also dip into the 60s.

Issued at 300 PM EDT Thu Oct 8 2026

Tonight-Friday...Gradient tightens north of a stalled front across the area, with E/NE winds increasing to around 20 knots across the Volusia waters this evening. Have issued a Small Craft Advisory for the Volusia waters for these hazardous boating conditions, starting at 8 PM tonight that will linger through early Friday morning. Winds then diminish slightly as front begins to slowly drift northward, remaining out of the E/NE across the Volusia waters and out of the SE south of the front, with speeds 10-15 knots. However, poor boating conditions will continue across the northern waters for seas up to 6 feet. Poor boating conditions then expand across the rest of the coastal waters into Friday night as SE winds increase up to 15- 20 knots as front continues northward.

High coverage of showers and storms will continue through late week, which will be another hazard to boaters.

Saturday-Tuesday...Poor to potentially hazardous boating conditions continue across the waters into Saturday/Saturday night, as S/SE winds persist around 15-20 knots. Winds diminish to 10-15 knots on Sunday and then become N/NW into early next week behind a passing front. Wind speeds look to remains below 15 knots behind the front.
Seas will range from 3-5 feet Saturday, decreasing to 2-4 feet Sunday through Tuesday.

Scattered to numerous showers and storms will continue through the weekend, with drier conditions across the waters into early next week behind the front.

AVIATION
(18Z TAFs)
Issued at 125 PM EDT Thu Oct 8 2026

A weak frontal boundary will continue to meander across central FL over the next 24 hours. Very high moisture values in association will provide for elevated heavy shower and storm chances. Threats to aviation include lightning, locally gusty winds, and torrential downpours. Lightning storm probabilities continue to increase thru the afternoon and early evening esp from MCO/MLB and points southward to the Treasure Coast terminals. In addition, CIGs continue to fluctuate, at times as low as IFR.
Still anticipate a general VFR/MVFR trend outside of convection.
E/NE winds increase this evening at DAB/LEE, with a few gusts to around 20 kt or so. Trending quieter after 03-05Z tonight, but CIGs will continue to need monitoring.

For Fri, perhaps a bit lower coverage (SCT-NMRS) with greatest threat I-4 northward as front lifts northward. Winds veer more ESE/SE across ECFL with speeds 8-12 kts. CIGs VFR/MVFR, local IFR invof convection, with lowest CIGs again near I-4 northward.
