.KEY MESSAGES...
Issued at 215 AM EDT Thu Oct 29 2026

- Another cycle of minor to moderate coastal flooding is expected
  this morning. Do not drive your vehicle into salt water. Follow
  local officials` advice to avoid flooded areas.

- Dangerous conditions will persist at our beaches through the
  weekend. Rough surf and numerous rip currents exist along our
  entire shoreline, and significant erosion has occurred. Stay out
  of the ocean. Mariners should reconsider Atlantic boating due to
  gusty winds and 5 to 10 ft seas.

- Onshore flow continues through the weekend. Scattered showers
  and gusty winds of 20 to 30 mph are forecast. The threat of
  locally excessive rain may increase from late Saturday into
  Sunday.

.DISCUSSION...
Issued at 215 AM EDT Thu Oct 29 2026


             -----------Synoptic Overview-----------

Flat mid-level ridging continues to extend from the Gulf into the
Southeast U.S. this morning. A quasi-zonal polar jet extends over
the northern U.S. A weak area of low pressure sits over the Bahamas,
to the south of a sprawling surface high over the Appalachians. A
persistent pressure gradient, responsible for the long duration
of fresh northeasterly flow over the Florida Peninsula, remains
in place. PWAT (moisture) values are still slightly above normal
for late October.

A weak mid-level ridge axis is forecast to move over Florida
late this week, nudging the low farther east and away from
the Bahamas. Behind a jet streak passing over the Great Lakes,
another impressive continental high should be summoned from the
Northern Plains, reaching the Mid-Atlantic states by Saturday
night. This will keep a pressure gradient over Florida through at
least early Monday.

Associated with the subtropical jet, a disorganized pocket of
vorticity currently sits over northern Mexico. Ensemble guidance
suggests this energy will move toward the east, reaching Florida by
Sunday. Expect some interaction with the persistent onshore flow
and moisture; nearly half of the 28/12Z grand ensemble suggests
this outcome.

Mid-level heights are forecast to rise through the middle
of next week, with onshore surface flow continuing but slowly
relaxing. Attention then turns to another disturbance within the
subtropical jet late next week. The latest ensemble clusters show
a trough reaching the Southeast by around next Thursday. Its cold
front may reach the state just beyond the 7-day forecast period,
with unsettled conditions potentially returning at that time.

             -------Sensible Weather & Impacts-------

Today - Saturday...

Persistence has been the key to the forecast, and we don`t see
any wholesale changes as we end the week. We will continue to have
coastal and marine hazards, along with breezy to windy conditions
and periodic showers coming off of the Atlantic.

The highest water levels of this prolonged event appear to be behind
us. This month`s king tides begin to diminish as we move past the
full moon. While still gusty, the wind-driven surge lessens a bit
as well. However, minor to moderate coastal flooding remains likely
today, with gradual improvement expected over the next several
high-tide cycles. Peak water levels are anticipated from mid to
late morning before decreasing through the afternoon. Our Coastal
Flood Warning is set to be replaced by a Coastal Flood Advisory
at 2 PM today.

We will keep the High Surf Advisory through this evening as
breakers up to 7 feet remain possible. With numerous rip currents,
interrupted sand bars, erosion, and rough surf, we strongly
recommend that residents and visitors stay out of the ocean and be
very careful if venturing to our beaches!

Scattered showers remain in the forecast, with a low chance (<25%)
for lightning. A few gusts of 30-35 mph may accompany the heavier
showers. Shower coverage is expected to ramp up on Saturday, and
we will need to monitor for any bands of heavy rain that develop,
especially south of Melbourne.

Outside of any rain, we still forecast occasional wind gusts of
20-30 mph. More breaks of sun are expected, so high temps will
warm back into the low/mid 80s.

Sunday - Monday...

The setup appears favorable for an uptick in rain and even isolated
(20%) lightning coverage. Statistical guidance has already increased
rain chances to 60-80% on Sunday. The deep onshore flow combined
with modest upper jet diffluence is at least somewhat concerning
for the potential of locally heavy rain. This may lead to flooding
of poorly drained areas, especially along the coast on Sunday.

The slow-moving feature begins to exit into the Atlantic on
Monday, but the onshore flow and lingering moisture should provide
above-normal coverage of showers.

Meanwhile, beach conditions are likely to remain hazardous. A
slight uptick in onshore flow may be enough for us to need
another High Surf Advisory for a portion of this period. Either
way, life-threatening rip currents and rough surf are expected
to persist.

Tuesday - next Thursday...

Onshore flow should begin to relax as high pressure nudges over
the peninsula. This allows rain chances to decrease to 20-30% for
the middle of next week. As mentioned in the overview, the next
signal is a subtropical jet stream disturbance that reaches the
Southeast U.S. by around next Thursday. Its front may approach the
area by late next Thursday or Friday (11/6), giving us our next
chance for at least scattered showers and storms. High temps
should remain warm, in the low/mid 80s.

It`s far too early to tell whether the front late next week poses
a threat for strong to severe storms. However, the overall pattern
suggests an enhanced subtropical jet developing as we head deeper
into November. This is in line with expectations from a strong El
Nino, and it is a key component to the periods of active weather
we expect to see this upcoming winter.

.MARINE...
Issued at 215 AM EDT Thu Oct 29 2026

Poor to hazardous boating conditions will persist over the local
Atlantic waters of Central Florida through at least the upcoming
weekend. A weak low will move away from the Bahamas over the next
couple of days. However, another strong area of high pressure
will drift toward the Mid-Atlantic this weekend. This will keep
moderate to fresh onshore winds in place. Scattered to, at times,
numerous showers are forecast.

NE winds 15-20 kt through Friday, with seas 5-10 ft. Winds turn
ENE on Saturday, then ESE on Sunday, 20-25 kt both days. Seas 6-10
ft this weekend. Intracoastal and inshore waterways very choppy
to rough.

.AVIATION...
(06Z TAFs)
Issued at 138 AM EDT Thu Oct 29 2026

Primarily VFR conditions are forecast outside of showers. Expect off
and on showers through the TAF period with ENE flow in place. TAFs begin
with ENE winds at 8kts-12kts with gusts up to 15kts-18kts before increasing
after 14Z with gusts up to 18kts-25kts. TEMPO and PROB30 groups exist
for MVFR CIGs/VIS between 15Z-19Z at the TAF sites except KLEE and
KISM, as well as at KFPR between 06Z-07Z.
