.KEY MESSAGES...
Issued at 235 PM EDT Sat Oct 3 2026

- A wet, unsettled pattern is forecast to persist across east
  central Florida through this weekend and next week. Minor
  flooding, lightning, and gusty winds will be possible with
  activity.

- A high risk of rip currents continues through the remainder of
  today and is expected to persist through the rest of the weekend
  at all east central Florida beaches. Entering the surf is not
  advised!

- Near to slightly above normal temperatures continue through
  early next week across east central Florida. Peak heat indices
  of 100F and greater in some spots cannot be ruled out. Remain
  adequately hydrated!

.DISCUSSION...
Issued at 235 PM EDT Sat Oct 3 2026

Through Tonight...A slower start to shower and storm development
today, with higher coverage of clouds this morning helping to
limit daytime heating slightly. However, as clouds have cleared a
bit into this afternoon and an outflow boundary from activity
earlier near the Treasure Coast has pushed northward, isolated
showers and storms have started to develop. Increasing coverage of
activity is anticipated over the next several hours, with the
best chances focused primarily across the interior (40-50%).
Persistent 10 to 15 mph steering flow will help keep showers and
storms moving, with less of a concern for flooding through the
remainder of today. Instability from daytime heating will support
isolated storm development, with occasional lightning strikes and
wind gusts of 45 to 50 mph possible. General storm motion will be
to the north-northwest. Hi-res guidance favors activity
diminishing into the late evening and overnight hours, with mostly
dry conditions anticipated across the peninsula. Isolated showers
cannot be ruled out across the local Atlantic waters, but there
is low confidence in this. Overnight temperatures fall into the
70s, warmest along the coast. A high risk of rip currents
continues overnight at all east central Florida beaches and will
likely be extended into tomorrow. Entering the surf is not
advised.

Sunday-Monday...Mid-level ridging situated across the Florida
peninsula slowly weakens through Sunday, with a broad trough
extending southward towards Florida into Monday. At the surface,
high pressure across the Atlantic gets kicked farther offshore on
Sunday as a front slowly pushes across the southeastern US, where
it is then anticipated to push into north Florida on Monday. A
moist air mass will remain in place across the Florida peninsula
thanks to both south to southeasterly flow at the surface
continuing to advect moisture towards the area and the frontal
boundary pushing moisture out ahead of itself towards Florida.
While PoPs on Sunday are forecast to remain fairly similar to
today (30-50%), there is an uptick in chances on Monday (50-70%)
as the frontal boundary approaches. Rain chances will follow a
fairly diurnal pattern on Sunday, with the sea breeze assisting in
development as it pushes inland. Monday, the pattern is driven
more by the frontal boundary, though additional support by the sea
breeze will also help. Given the multiple prior days of rainfall,
minor flooding is expected to be a concern through the remainder
of the weekend and into early next week, especially as model
guidance indicates the potential for some weaker steering flow.
Isolated to scattered storm activity will also be possible each
afternoon, though modest instability could be a limiting factor to
more robust development. Lightning strikes and wind gusts of 45
to 50 mph will be possible with any activity that does develop.
While showers and storms are forecast to slowly diminish into the
overnight hours on Sunday, lingering activity across the peninsula
on Monday cannot be ruled out given the front to the north.
Scattered shower and even storm development across the local
Atlantic waters will be possible each night.

Given the moist air mass and the predominant south to southeast
flow, temperatures are anticipated to remain warm across east
central Florida, staying near to slightly above normal. Highs
reach the upper 80s to low 90s each afternoon, combining with the
humidity to produce peak heat indices of 100F and greater nearly
areawide. Hydration will be key for those spending extended
periods of time outdoors. Overnight, temperatures remain near to
slightly above normal in the low to mid 70s.

Tuesday-Friday...Through the remainder of the upcoming week, an
unsettled pattern is anticipated to persist across east central
Florida. The aforementioned broad mid-level trough situated across
the southeastern US is forecast to remain in place, with some
indication of shortwaves moving along it throughout the week. At
the surface, the frontal boundary approaching from the north is
forecast to stall across the peninsula, generally meandering
across central Florida. There are some indications for the
development of a low along the stationary boundary off the
northeast Florida coast towards the middle of the week, which
would have implications on beach and boating conditions. There is
some uncertainty relative to timing of development and strength of
the low. This will continue to be closely monitored and
confidence in the outcome will increase as model guidance comes
into better agreement on a solution. Overall, a plume of moisture
along the boundary will support continued higher coverage of
showers through next week, with PoPs staying elevated (60-80%).
Flooding will remain the primary concern locally, especially given
the multiple days of rainfall and saturated soils. Isolated to
scattered storm development will be possible with activity, with
lightning and gusty winds anticipated to be the primary storm-
related hazards. Current guidance trends follow a somewhat diurnal
pattern with afternoon and early evening forecast to be the peak
coverage of showers and storms, though lingering activity across
the peninsula and ongoing development across the local Atlantic
waters through the nighttime hours cannot be ruled out. Outside of
showers and storms, northerly flow is forecast to develop through
the middle of next week, with winds gradually becoming more
onshore later. Temperatures are forecast to remain generally near
normal values, though the moist air mass will cause peak heat
indices to continue creeping towards 100F in some spots,
especially across the Treasure Coast.

.MARINE...
Issued at 235 PM EDT Sat Oct 3 2026

Broad high pressure across the Atlantic is shoved farther east as
a frontal boundary drifts southward across the southeastern US,
with the boundary becoming stationary across the Florida peninsula
next week. While boating conditions are anticipated to remain
generally favorable through at least Tuesday, there is indication
that conditions could deteriorate and become poor to hazardous mid
to late week as a low develops along the stationary boundary just
north of the local waters. There remains some uncertainty
relative to the strength of the low, but confidence in evolution
should increase as time moves forward.

Seas are forecast to remain generally between 2 to 4 feet tonight
through Tuesday, with wind speed staying below 15 knots.
Southeasterly winds tonight through Sunday become more southerly
into Monday, with a shift more onshore each day as the sea breeze
develops. By Tuesday, winds become more variable with the
potential for the developing low north of the waters. Wednesday,
northerly winds of 10-15 knots support building seas of 3 to 6
feet, highest across the Gulf Stream waters. Brief periods of 7
foot seas cannot be ruled out. A wet pattern will also persist
across the local Atlantic waters through this weekend and into
next week, with scattered to numerous showers and isolated to
scattered storms possible. Storm hazards will include lightning
strikes, wind gusts in excess of 30 knots, heavy downpours, and
locally higher seas.

.AVIATION...
(06Z TAFs)
Issued at 141 AM EDT Sun Oct 4 2026

Rounds of isolated onshore-moving showers continue along the coast
early this morning, primarily south of the Cape. Looking toward
the afternoon, guidance points toward scattered showers and
storms developing across the interior, and VCTS is mentioned at
the inland terminals. Some of this activity may pushback eastward
this evening, potentially lingering a few hours beyond sunset
across the interior and spreading towards DAB. East-southeast
winds increase up to 10-12 kts into the afternoon.
