.NEAR TERM...
Issued at 209 PM EDT Sun Sep 28 2025

A northeast to southwest frontal boundary will be stalled along the 
NE FL coast this afternoon and evening. The boundary will move to 
the southeast of the area overnight, as northward moving tropical
system tracks east of southern FL. The boundary will continue to 
focus shower chances over mainly eastern counties, with a few
thunderstorms possible. With the expected cloud coverage,
Tonight's lows will trend above normal. 

&&

.SHORT TERM...
(Monday through Tuesday night)
Issued at 209 PM EDT Sun Sep 28 2025

Elevated winds over the local waters as Tropical Storm Imelda is 
expected to begin a shift northeast and then east away from the 
SE CONUS after passing across the Bahamas late Monday into 
Tuesday. Tropical Storm Watches remain in effect across the local 
waters beginning Monday morning. With elevated winds over the 
waters, coastal and beach hazards are expected through the day on 
Monday and into Tuesday, with High risk for life-threatening rip 
currents and High surf likely with larger waves further offshore. 
Additionally showers from the outer bands of the tropical system 
will look to push along coastal locations and some activity 
possibly making their way towards inland locations past the I-95 
corridor. 

Tuesday, Hazards along the local waters and coastal locations will
continue as winds will remain elevated as Tropical Storm Imelda 
will be moving away from the coast and the reinforced ridge over 
the area will persist breezy conditions. Drier air filtering into 
the area from the north-northwest will work to limit the chances 
of precipitation along inland locations, but coastal locations 
will likely still see some showers and occasional thunderstorms 
with the north-northeasterly flow along the coast.

Monday/Tuesday...Daytime highs in the 80s, upper 80s for inland
locations of NE FL. Overnight Lows in upper 60s over SE GA and
Suwannee Valley region, with the remainder of locations in the
lower 70s. 

&&

.LONG TERM...
(Wednesday through next Sunday)
Issued at 209 PM EDT Sun Sep 28 2025

Drier air will continue to settle into the region midweek as
Tropical Storm Imelda continues to move away from the CONUS.
Scattered chances of showers and isolated storms along the coast
as north-northeasterly onshore flow will continue to bring in
moisture from the Atlantic through the remainder of the week. With
the continuing northeasterly onshore flow, we could still see
impacts to the coast and local waters during the later half of the
upcoming week. Temperature highs will trend down to the upper 70s
and lower 80s by midweek, but begin to tick upward by the weekend
with most locations in the 80s.

.AVIATION...
(18Z TAFS)
Issued at 209 PM EDT Sun Sep 28 2025

Occasional MVFR cigs along the TAF sites with chances of showers 
increasing for coastal TAFs. The chance of MVFR cigs will continue
tonight, so kept the mention of prevailing MVFR. Inland sites may
see IFR possibility with scattered decks below 1 kft and lower
vsby as Fog develops during the overnight hours. Winds ease a bit
overnight but will likely pick up once again by the early daytime
hours on Monday.

&&

.MARINE...
Issued at 209 PM EDT Sun Sep 28 2025

A frontal zone will be located across the waters through Tonight 
into Monday. Northward moving Tropical depression number 9 will be 
east of Cape Canaveral Monday evening. The depression will then 
begin to track to the northeast, then east Tuesday into Tuesday 
night. Elevated winds and seas are expected as the system passes by.

Interests should continue to monitor the latest forecasts from the 
National Hurricane Center.

High pressure will strengthen to the north northeast later in the 
week, leading to a period of elevated conditions in what will become
a persistent onshore flow.

Rip currents: Increasing onshore flow and building surf will lead
to higher rip current risk today and continuing into next week as
surf continues to build. There is a good chance of high surf for 
area beaches sometime on Monday which will likely continue into at
least mid week. Surf builds up to the 7-10 ft range and could be 
higher in some spots. Peak wave heights generally occur in the 
Monday night through Tuesday evening time frame.

.HYDROLOGY/COASTAL FLOODING POTENTIAL... 
Issued at 225 AM EDT Sun Sep 28 2025

Mostly a marginal risk of excessive rainfall for the coastal areas
through Tuesday. Highest rainfall amounts of 1-3 inches are 
possible for the coast with locally higher of about 4 inches. 

Coastal flooding potential: Coastal water levels will be rising 
Monday through Wednesday. PETSS mean water level guidance 
generically shows only minor tidal flooding concerns while 
localized spots could see slightly higher potential. Current 
forecasts show up to about 2 ft MHHW at the coast and 1-2 ft MHHW 
for the St Johns River Basin and Intracoastal Waterway.
