Area Forecast Discussion
National Weather Service Melbourne FL
340 PM EDT Mon Oct 23 2023
...New DISCUSSION, MARINE, AVIATION, HYDROLOGY...
.DISCUSSION...
Tonight-Tuesday...The area of surface high pressure will remain in
place along the Atlantic seaboard just north of the peninsula
tonight into tomorrow, keeping conditions mostly dry. Amplification
aloft of the mid-level ridge will lead to strengthening of the high
at the surface, resulting in a tighter pressure gradient locally,
leading to increasing easterly winds. As a result, moisture will
continue to be advected toward east central Florida tonight into
tomorrow, resulting in the development of scattered cloud coverage
tonight into Tuesday. Models continue to remain dry, but cannot rule
out a stray shower or two developing across the local Atlantic
waters. Overall though, the forecast remains dry through Tuesday.
Temperatures will remain seasonable, with afternoon highs in the low
80s and overnight lows in the mid 60s across the interior to the low
70s along the coast.
Wednesday...Stout ridging persists over the eastern US, with
surface high pressure meandering around the Mid-Atlantic, mid-
level high pressure over the northern Gulf Coast, and upper level
ridging over the GOMEX. Thus, breezy to windy onshore flow will
continue, as the pressure gradient remains tight, with ESE winds
around 15mph and gusts to around 25mph. Though rainfall is not
expected, with PoPs around 5-10%, a few isolated light showers
cannot be ruled out in the marine stratocu. Any accumulations will
be minimal.
Onshore flow will keep temperatures near-normal, with highs in the
lower 80s. However, overnight lows will be slightly above normal, in
the upper 60s inland and lower 70s along the coast.
Thu-Mon (modified previous)...The mid/upper level ridging will
weaken slightly into the extended with center of mid-level high
pressure sinking slowly into the eastern Gulf. While the pressure
gradient does gradually weaken during this time (into late work-
week), the fairly deep onshore flow will continue across the region.
Will keep conditions mostly dry thru Sat night (still cannot rule
out an isolated sprinkle/shower, especially along the Treasure
Coast), but may see a 20-30pct chance for shower activity as we head
thru the weekend and into early next week, as moisture increases
slightly. Though most locations will still remain dry and any QPF
will be light. High temps continue in the L-M80s, but could see some
U80s later in the period. Lows continue in the M-U60s to L70s
(toward coast).

.MARINE...
Issued at 331 PM EDT Mon Oct 23 2023
Tonight-Tuesday...Boating conditions are forecast to deteriorate
starting tonight and continuing through the next couple of days. ENE
winds between 15 to 20 knots will develop as a result of a
tightening pressure gradient across the Florida peninsula and the
local Atlantic waters, with gusts up to 30 knots possible. As a
result of this increasing onshore flow, seas are also forecast to
build to 4 to 8 feet tonight into tomorrow. As a result of the winds
and seas, Small Craft Advisories have been issued for the offshore
waters and nearshore Treasure Coast waters starting tonight.
Elsewhere, small craft should exercise caution. Dry conditions will
persist as the surface high remains in place just north of the area.
Cannot fully rule out some stray to isolated shower development as a
result of the onshore flow, but confidence is too low to include in
the forecast at this time.
Wednesday-Friday...High pressure over the area will maintain
breezy to windy conditions over the local Atlantic waters. Current
Small Craft Advisories in effect through Thursday morning will
likely need to be expanded and extended, as hazardous boating
conditions persist into the weekend. Onshore winds 20-25kts at
times, with seas up to 8-10ft, likely through the period. Though
will start to see winds decrease on Friday as the high pressure
begins to weaken. Isolated, light showers cannot be ruled out,
especially later in the week.

A Moderate Risk of dangerous rip currents continues at all central Florida Atlantic beaches. Always swim near a lifeguard, and never enter the ocean alone. .WIND AND SEA IMPACT... Onshore flow will steadily increase across the local Atlantic waters today becoming 15-20 kts after sunset. Small Craft should exercise caution tonight. .RIVER FLOOD IMPACT... The Saint Johns River at Astor will remain in Minor Flood Stage for the foreseeable future. There is a chance the river level at Astor may creep upward once again this week as breezy E/NE winds develop. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY. A large and strong high pressure ridge centered well north of Florida will produce breezy to windy conditions across east central Florida and the adjacent Atlantic waters. Boating and beach conditions will become hazardous early Tuesday, with building seas over the open ocean, choppy surf, moderate to large breaking waves, and a Moderate to High risk of rip currents in the surf zone. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed today and tonight. Law
