.DISCUSSION...
KEY MESSAGE 1: Minor coastal flooding is expected along
portions of the South Carolina coast through Saturday.

Astronomical tides will continue to trend lower the rest of
this week as we get further away from the Full Moon and perigee.
Decent tidal anomalies will stay in place the rest of this week
due to persistent and elevated northeast winds. The Friday and
Saturday early afternoon high tides are forecasted to reach
minor coastal flooding thresholds at the Charleston Tide Gauge.
Therefore, Coastal Flood Advisories will be needed. The coastal
flooding threat should finally end early next week.


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

Ongoing elevated winds, seas and tides will support a high risk
for rip currents along the Georgia beaches today, with a
moderate risk expected elsewhere across our South Carolina
beaches.

The rip current risk then 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.

Dry conditions should prevail through Halloween with high
pressure directly overhead the next 48 hours. The main talk will
be the temperatures as highs today should climb into the 80s
inland and upper 70s along the coast. By Saturday the upper
ridge will begin to breakdown as a shortwave trough ejects
across the central US. Weak surface high pressure will wedge
into the Carolinas keeping temperatures in the mid 70s across
the Tri- county area with warmer temperatures south of the
surface wedge front across coastal Georgia.

Our persistent upper pattern will finally switch by Sunday as
the first of a couple systems moves through the area.
Unfortunately for those looking for relief from drought
conditions this system Sunday has continued to trend drier and
most areas will likely see no rain this weekend. The best chance
for rain looks to be across far southern coastal Georgia late
Sunday into Sunday night. Other than that, expect breezy
conditions along the coast as a surface low develops offshore
and lifts northeast into the Atlantic Sunday into Monday. Wind
gusts to around 20 to 25 mph will be possible along the
immediate coastline. After Sunday, attention turns to the middle
part of the week as the second and much stronger system moves
into the eastern US. Guidance appears to be in fairly good
agreement of the system being there, the question is when does
it arrive and how strong will it be. Nonetheless, this system
certainly catches the eye as our next real rain maker and
potentially could bring a rumble of thunder to the middle part
of next week. We will continue to monitor this system in the
coming days as details become clearer.

.AVIATION /13Z FRIDAY THROUGH TUESDAY/...
IFR conditions continue this morning at KCHS and KJZI as fog
and low ceilings have developed across Charleston metro area.
VFR coniditons prevail elsewhere this morning with light north-
northeasterly winds. VFR conditions should return by mid-
morning to the area and persist throughout the day with a light
northeasterly wind prevailing. Winds will relax after sunset to
below 5 knots.

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

&&

.MARINE...
Through Tonight: Seas and winds will slowly diminish through the
day. 6 ft+ seas will linger over the offshore waters into
tonight and the Georgia offshore waters through this afternoon.
Small Craft Advisories remain in effect for the Georgia
nearshore and offshore legs.

Saturday through Tuesday: Restrengthening of the inland wedge
to the north this weekend and then the development of a weak
coastal trough afterwards will drive northeast gusts back up to
25-30 kt and building seas above 6 ft. Another round of Small
Craft Advisories for the nearshore waters could be needed
Saturday afternoon potentially into Tuesday. A Small Craft
Advisory for the Georgia offshore waters will likely continue
through the entire period as 6 ft seas or greater will remain.
