Area Forecast Discussion
National Weather Service Charleston SC
520 PM EDT Mon Apr 27 2026

.WHAT HAS CHANGED...
Minor change made to the Marine Section to remove Small Craft
Advisories across nearshore Georgia and southern nearshore South
Carolina waters.

&&

.KEY MESSAGES...
- 1) High pressure will settle over the region and yield breezy,
  dry conditions.

- 2) Minor coastal flooding likely with the evening high tide along
  the southeast South Carolina coastline.

- 3) Rain chances will increase from mid-week through the
  weekend, though no significant impacts are expected at this
  time.

&&

.DISCUSSION...
KEY MESSAGE 1: High pressure will settle over the region and yield
breezy, dry conditions.

As high pressure continues to build into the region, expect breezy
northeasterly flow to persist into the afternoon, before gradually
diminishing this evening as the pressure gradient relaxes.
The overcast clouds have been stubborn to erode today, and will
continue to anticipate some sunshine later this afternoon/evening.
Temperatures have been nudged down given the lack of diurnal
heating we`ve seen, and therefore, expect highs in the low 70s
across southeast South Carolina and mid to upper 70s across
southeast Georgia. PWAT values will drop near 0.5 inches this
afternoon as dry air continues to filter into the region. The
SCFC Burn Ban remains in effect and the minimum RH values will
dip into the 30 to 40% range (away from the coastline) this
afternoon with the lowest values across far interior southeast
Georgia.

KEY MESSAGE 2: Minor coastal flooding likely with the evening high
tide along the southeast South Carolina coastline.

As astronomical tide levels are beginning to rise as we move closer
to he upcoming (5/1) full moon, strong northeasterly winds combined
with the current tide departure of 1.46 ft will likely cause
for minor coastal flooding along the southeast South Carolina
coastline with this evening`s high tide (~6:15pm). For the
evening high tide cycle, the astronomical tide is 5.59 ft MLLW
meaning we would need a departure of 1.41 ft the minor coastal
flood threshold of 7 ft MLLW. Therefore, with the aforementioned
current tide departure, this would mean we will likely see a
high tide a little above 7 ft MLLW this evening. Hence, a
Coastal Flood Advisory has been issued for Charleston and
Coastal Colleton counties until 8PM EDT this evening.

KEY MESSAGE 3: Rain chances will increase from mid-week through
the weekend, though no significant impacts are expected at this
time.

A surface low tracking across portions of Tennessee and the Ohio
River Valley could bring periods of scattered showers and isolated
thunderstorms Wednesday into Thursday morning. Instability remains
limited, so any thunderstorms that develop are expected to be weak
and non-severe, with low potential for significant impacts.

Another system could affect the region early this weekend, bringing
another round of rain chances. Similarly, the risk of hazardous
weather remains low at this time.

&&

.AVIATION /21Z MONDAY THROUGH SATURDAY/...
18Z TAFs: As the clouds are slow to erode across the region, MVFR
cigs in place at KCHS/KJZI/KSAV terminals for a couple more hours.
Model guidance continues to suggest conditions returning to VFR
somewhere between 20-21Z time period. Breezy northeasterly winds
have diminished, and beginning to turn more easterly as we head into
the evening.

Extended Aviation Outlook: Showers and isolated thunderstorms
associated with a cold front could bring flight restrictions
Wednesday into Thursday morning.

&&

.MARINE...
Through tonight: Northeasterly winds continue to range from 15 to 20
kt with gusts up to 25 kt across a portion of local waters. Expect
seas to range from 4 to 6 ft across nearshore waters (largest
off the Charleston County Coast and 5-7 ft across outer waters.
Small Craft Advisories remain in effect for northern nearshore
South Carolina waters and outer Georgia waters as a result, but
conditions will continue to improve during the evening and
overnight. Given the trend, the northern nearshore South
Carolina waters are expected to see conditions drop below Small
Craft Advisory levels this evening, followed by outer Georgia
waters later tonight.

Heading into Tuesday, the pressure gradient will weaken over the
local waters as the high pressure shifts offshore. Marine conditions
are expected to deteriorate Wednesday as a cold front approaches the
region, and thus Small Craft Advisories could be needed once again.
Winds could gust near 25 knots, with seas building to 3 to 5 ft.
Another system this weekend could bring another period of elevated
winds and seas, potentially leading to additional Small Craft
Advisories.

Rip Currents: A Moderate Risk of rip currents continues at all
beaches through the rest of the afternoon given the ongoing strong
northeasterly winds and elevated seas.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...None.
SC...Coastal Flood Advisory until 8 PM EDT this evening for SCZ149-
     150.
MARINE...Small Craft Advisory until 8 PM EDT this evening for AMZ360.
     Small Craft Advisory until 5 AM EDT Tuesday for AMZ384.
