  possible.
- Dangerous beach and marine conditions persist, including coastal
  flooding, life-threatening rip currents, rough surf, and minor
  to moderate beach erosion especially near times of high tide. A
  Coastal Flood Warning remains in effect for the Volusia and

.DISCUSSION...
Issued at 320 AM EDT Fri Oct 10 2025
Today-Tonight...A weak boundary is forecast to settle across
central Florida today, resulting in a moist airmass remaining
in place locally. Forecast PWAT values exceed 2" areawide, with
high rain chances anticipated across east central Florida. PoPs
remain between 60-80%, with the greatest chances focused along the
coast. Flooding remains the primary concern for today, especially
given the highly saturated soils across the area from several
previous days of rainfall. It will not take much rainfall to cause
flooding given these conditions, so areas that see training bands
of showers or receive multiple rounds of showers will be
particularly at risk for flash flooding. Widespread rain totals of
1 to 3" are forecast, with locally higher amounts of 5" and
greater possible. A Flood Watch remains in effect for the coastal
counties through 8 PM tonight. Sufficient MUCAPE of 1500 J/kg and
greater will support the potential for storm development today,
with lightning strikes likely the primary concern with anything
that develops, in addition to the heavy downpours and flooding
concerns. Gusty winds from storms cannot be ruled out, though
confidence is lower. The chance for storm development decreases
into the overnight hours.
Aside from showers and storms, guidance continues to favor a tight
pressure gradient across the area today, which will be further
enhanced by the development of a surface low tonight. Northeast
winds persist at 10 to 15 mph across the area, with gusts to 25
mph possible, especially along the coast. Winds decrease slightly
overnight. The persistent onshore flow paired with higher seas will
also maintain hazardous beach conditions through today. Coastal
flooding, minor to moderate beach erosion, high surf, and a high
risk of rip currents are all forecast at the local beaches.
Entering the ocean is strongly discouraged.
High cloud coverage from the greater moisture present across the
area will limit daytime heating, with highs only reaching the
upper 70s to low 80s. Overnight temperatures fall into the upper
60s to low 70s.
Saturday...Once the surface low develops Friday night, it is
forecast to slowly lift northeastward, dragging its attendant cold
front across the Florida peninsula. Drier air slowly starts to
intrude southward towards east central Florida, which will help
cut rain chances down to 30 to 40% on Saturday. Low risk for
storms on Saturday, especially given less instability present. A
few lightning strikes cannot be ruled out entirely though, so
maintained a 40% chance of storms. Any shower and storm activity
that manages to develop is forecast to subside into the overnight
hours, especially as the front moves south of the area.
With the surface low so close to the area and the pressure
gradient tightening locally, winds are anticipated to be the
breeziest on Saturday, especially across Volusia County. Winds
back to out of the north-northwest at 15 to 20 mph with gusts to
30 mph possible across the area. Conditions begin to improve into
the overnight hours as the low pulls away from Florida.
Coastal hazards are anticipated to persist into Saturday. Similar
to today, coastal flooding, rough surf, minor to moderate beach
erosion, and a high risk of rip currents will continue. Residents
and visitors continue to be strongly advised to avoid the ocean
and beaches.
Temperatures across the area remain fairly consistent in the upper
70s to low 80s during the afternoon hours, with lows falling into
the 60s behind the cold front.
Sunday-Thursday...Drier air is forecast to continue settling
across the peninsula through the extended period behind the front.
As a result, rain chances drop below 20% areawide through the
remainder of the weekend and into the middle of next week.
Temperatures on Sunday remain slightly below normal in the upper
70s to low 80s, but increase to near- normal in the low to mid 80s
Monday and beyond. Low temperatures fall into the 60s areawide,
with the cooler temperatures focused across the interior,
especially near and north of the I-4 corridor.
Coastal hazards are anticipated to slowly improve through the
extended period. Coastal flooding due to high astronomical tides
and a high risk of rip currents due to long period swells are
anticipated to continue through at least Sunday. Longer range
guidance hints at lower chances for coastal flooding beyond
Monday, but will continue to monitor and adjust the Coastal Flood
Advisory as needed.

.MARINE...
Issued at 320 AM EDT Fri Oct 10 2025
Poor boating conditions are forecast to persist across the local
Atlantic waters through this weekend. A front drifts southward
across the waters today with an area of low pressure lifting
northeastward across the area Saturday, with the cold front moving
across the local waters on Saturday. Rain chances remain high
through tonight at 70 to 90 percent, falling to 30 to 50 percent
on Saturday. East-northeast winds 15 to 20 knots back to out of
the north-northwest on Saturday at 15 to 25 knots. Seas build up
to 8 to 9 feet across the offshore waters, with 4 to 7 foot seas
forecast elsewhere. A Small Craft Advisory for the Brevard and
Volusia waters expands to include the offshore Treasure Coast
waters early this morning, with the advisory continuing for these
marine zones through at least Saturday night. Behind the front,
winds diminish to 10 to 15 knots and seas are forecast to slowly
subside late this weekend into early next week, with a return of
generally favorable and dry boating conditions forecast from
Monday onward.

.AVIATION...
(06Z TAFs)
Issued at 150 AM EDT Fri Oct 10 2025
VFR/MVFR continues across northern sites with MVFR/IFR conds TIX-
MLB southward. Higher coverage of SHRA will remain at coastal
sites thru 16z, gradually spreading inland thru 21z. Depending on
how fast drier air arrives from the west, inland sites to DAB
could see lesser -SHRA by 00z Sat. NE winds pick up to 10-13 kt
(gusts around 20 kt, esp. MLB northward) 15z-00z. A mix of
VFR/MVFR conds are anticipated, though occasional degraded CIG/VIS
to IFR is possible (esp. at the coast). SHRA activity could linger
beyond 00z Sat. at coastal terminals.
