.DISCUSSION...
KEY MESSAGE 1: Minor coastal flooding is possible along
portions of the South Carolina coast early Saturday afternoon.

Water levels in Charleston Harbor could approach minor flood
stage early Saturday afternoon. One last Coastal Flood Advisory
could be needed for Charleston and Coastal Colleton Counties.

KEY MESSAGE 2: Continued risk for rip currents through the
weekend.

The rip current risk increases to high for all beaches by
Saturday, as increased northeasterly winds and seas become more
widespread.

Reminder: The local rip current program will end Saturday,
October 31 with the afternoon Surf Zone Forecast.

KEY MESSAGE 3: Quiet conditions through Saturday with somewhat
unsettled and breezy conditions Sunday into Monday.

Saturday: The ridge aloft begins to break down as a wedge of
high pressure meanders towards the northeast coast, setting up a
coastal trough just offshore. Expect winds to become gusty
inland to breezy along the coast throughout the day, with areas
along the coast likely seeing gusts of 25 to 30 mph during the
afternoon, possibly as high as 35 mph down near Darien. While
temperatures will be a touch cooler than today, normal to above
normal temperatures remain expected with highs in the mid 70s to
lower 80s, warmest across southeast Georgia. With low to mid
level moisture increasing throughout the day, partly cloudy
skies will become mostly cloudy. Can`t rule out some scattered
light showers near Darien, GA Saturday afternoon into the early
evening hours, though the rest of the area looks to remain dry
for any outdoor activities.

Lake Moultrie: As breezy winds develop Saturday morning, there
is a brief window shortly after sunrise where winds on Lake
Moultrie may briefly gust to near 25 knot. Confidence is not
high enough for a Lake Wind Advisory, but something to keep an
eye on.

Sunday: As the surface high begins to slowly decrease in
strength, gusty to breezy conditions remain across the area for
Sunday, with highs in the mid 70s. Models continue to show
mostly dry conditions for Sunday as the shortwaves look very
weak and isolated, with the coastal trough likely keeping
rainfall chances just offshore. The exception remains for areas
near Darien, GA as the coastal trough extends onto land, though
amounts look to remain light under a quarter of an inch.

Monday and Tuesday: The center of the surface high pressure to
our north begins to shift out into the Atlantic, with the
coastal trough remaining just offshore of our local waters.
Combined with increasing low-level moisture and a weak slow
moving shortwave, chances for light scattered showers will build
across the region Monday morning into the early overnight hours
on Tuesday. Otherwise, expect similar conditions to continue,
with gusty northeast winds and afternoon highs in the mid 70s
for Monday, rising into the upper 70s to lower 80s on Tuesday.
The forecast is currently calling for low chances for light rain
on Tuesday, though that is a bit uncertain as forecast
solutions begin to diverge on Tuesday.

Wednesday and Thursday: Forecast guidance is handling the
longwave trough and associated surface low pressure that they
have moving towards the eastwards from the central CONUS with
various solutions, leading to lowered confidence in the
forecast. General consensus is for the longwave trough to
continue shifting eastwards Wednesday into Thursday, though some
models have it becoming a closed off low and others are more
progressive, which should bring some chances for rain. The track
of the surface low looks to remain north of the area, with the
associated cold front aiding rainfall chances.

.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
VFR conditions are expected to prevail at KCHS, KJZI, and KSAV
through 00z Sunday. Currently, there are no concerns for early
morning fog and stratus like the last few mornings. There will
be more cloud cover than the last several days, mostly mid and
high level clouds. Northeast winds will strengthen and gust
frequently up to around 18-22 knots for much of Saturday.

Extended Aviation Outlook: Gusty northeast winds are possible
this weekend into Monday with an increased risk for rain impacts
Sunday into Monday.

&&

.MARINE...
Restrengthening of the inland wedge to the north overnight with
the development of a weak coastal trough will drive northeast
wind gusts back up to 25-30 kt, with building seas above 6 ft.
Small Craft Advisories have been issued for the Charleston
Harbor and all near-shore (out to 20nm) zones, starting Saturday
morning. The offshore (20-60nm) waters from Savannah to
Altamaha sound will continue their advisories. Wave heights will
build overnight to become 7 to 9 ft in the offshore (20-60nm
out) zones, and into the 5 to 8 ft range in the nearshore zones.
With high pressure lingering into the mid-week, northeast winds
will remain breezy during the day and gusty overnight, keeping
wave heights in the 5 to 8 ft range into Wednesday morning.
