Issued at 310 AM EDT Sat Oct 11 2025
Today-Tonight...An area of low pressure located off of the east
central Florida coast is forecast to slowly lift north-
northeastward today across the local Atlantic waters, aided by a
mid-level trough shifting northeastward over the Florida
peninsula. The tight pressure gradient due to the low will lead to
breezy conditions locally, with north to northwest winds of 10 to
15 mph and gusts to 25 mph possible. Winds may be slightly higher
along Volusia coast. Drier air has been noticed wrapping around
the northwest side of the low, visually depicted on the GOES19
Total PWAT viewer. This drier air will lead to lower rain chances
areawide today, with current PoPs generally sitting between
30-50%. The environment remains unfavorable for strong storm
development primarily due to lackluster instability (MUCAPE less
than 1000 J/kg), but occasional lightning strikes and wind gusts
to 45 mph cannot be ruled out with any storms that do manage to
develop. Brief heavy downpours will also be possible with shower
and storm activity, and areas that are well saturated from the
past several days of rainfall will be susceptible to localized
minor flooding. As the area of low pressure and its attendant
front move farther away from east central Florida, activity is
anticipated to move offshore and diminish, with drier conditions
forecast through the overnight hours.
A sneak peak at fall will be possible today thanks to
temperatures remaining just below normal. Highs only reach the
upper 70s to low 80s across east central Florida, with overnight
temperatures falling into the low to mid 60s tonight. Lows in the
upper 60s will be possible across the Treasure Coast.
Aside from the weather, a number of coastal hazards remain in
effect for the area. Coastal flooding, rough surf, minor to
moderate beach erosion, and a high risk of rip currents are all
anticipated to continue today. Heading to the beach is strongly
discouraged, and entering the ocean is discouraged even more due
to the hazardous conditions.
Sunday-Friday...The mid-level troughing swings northeastward
through the weekend and into early next week, with the surface low
and its associated front continuing to move northeastward away
from Florida. Broad high pressure is forecast to set up across the
eastern US into next week, gradually shifting southward towards
Florida by late week. Limited energy aloft paired with lower PWATs
mean that the extended forecast period looks to be fairly dry
across east central Florida, with rain chances anticipated to
remain below 20% through at least Thursday. North to northeast
winds are forecast to prevail through at least Thursday, veering
to out of the east on Friday. This onshore flow may lead to a
slight return of moisture, which could support some isolated
shower development Friday into Saturday. A great deal of
uncertainty remains at this point, and again, rain chances
generally remain at or below 20%. Temperatures are forecast to
remain near normal through next week, with highs generally in the
low to mid 80s and lows in the 60s. Late next week, lows may only
fall into the low 70s along the coast.
Coastal hazards look to continue through at least Sunday,
particularly coastal flooding and a high risk of rip currents.
Extensions in time of these hazards may be needed depending on how
tidal guidance trends over the next day or so. Residents and
visitors are encouraged to continue monitoring the forecast and
always heed the advice of local beach safety officials.

.MARINE...
Issued at 310 AM EDT Sat Oct 11 2025
Poor boating conditions persist across the local Atlantic waters
as an area of low pressure slowly moves north-northeastward today
through Sunday. North to northwest winds of 15 to 25 knots will be
possible through tonight, subsiding to 15 to 20 knots Sunday.
Seas of 6 to 10 feet will be possible across the local Atlantic
waters, with the higher seas focused primarily across the offshore
waters. A Small Craft Advisory remains in effect for all legs of
the local Atlantic waters, with various zones slowly dropping as
seas subside Sunday into Monday. Beyond Monday, boating conditions
are forecast to be generally favorable, with northwest to
northeast winds of 10 to 15 knots and seas remaining between 3 to
6 feet. Some building to 7 feet across the offshore waters cannot
be ruled out towards the middle of next week.
Rain and storm chances range between 30-50% today due to the low
pressure located across the local waters. Drier air moves into the
area behind the low and its attendant front Sunday through the
remainder of the period, with rain chances falling generally to
20% and less.

MVFR/IFR CIGs will continue thru at least 12z between ISM and DAB,
extending west to LEE. VCSH remain primarily at DAB as -SHRA
rotate around a low pressure system offshore of the ECFL coast.
Iso./sct. -SHRA are forecast from MCO eastward after 16z-18z,
with highest confidence in occurrence north of VRB. N/NW winds
are forecast 8-12 kt VRB southward, reaching 10-15+ kt MLB
