What forecasters said that day

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Charleston, SC wrote its last area forecast discussion before this flash flood warning went out at Jul 14, 4:22 PM EDT, 33 minutes earlier. Its key messages:

1) Rounds of showers/thunderstorms expected today with heavy rain and isolated flash flooding possible. A few thunderstorms could also become strong with damaging wind gusts.
2) Minor to moderate coastal flooding remains possible during the evening high tide cycles along the Charleston to Colleton county coast through Wednesday.
3) Hot and humid conditions are expected to return to the area late this week through early next week. Heat Advisories could be needed.

Area forecast discussion, Jul 14, 4:22 PM EDT, 33 minutes before

Area Forecast Discussion
National Weather Service Charleston SC
422 PM EDT Tue Jul 14 2026

.WHAT HAS CHANGED...
A Coastal Flood Advisory has been issued for the SE GA coastline
and southern SC coastline for Minor Flooding forecast at the
Fort Pulaski Tide Gage.

&&

.KEY MESSAGES...
- 1) Rounds of showers/thunderstorms expected today with heavy
  rain and isolated flash flooding possible. A few
  thunderstorms could also become strong with damaging wind
  gusts.

- 2) Minor to moderate coastal flooding remains possible during
  the evening high tide cycles along the Charleston to Colleton
  county coast through Wednesday.

- 3) Hot and humid conditions are expected to return to the
  area late this week through early next week. Heat Advisories
  could be needed.

&&

.DISCUSSION...
KEY MESSAGE 1: Rounds of showers/thunderstorms expected today
with heavy rain and isolated flash flooding possible. A few
thunderstorms could also become strong with damaging wind gusts.

A stalled boundary remains positioned off the southeast coastline
this afternoon, which will be the synoptic driver of afternoon
showers and thunderstorms today. The PWAT value with this
morning's 12Z KCHS RAOB Sounding was 2.25", which is above the
90th percentile of 2.11" according to SPC climatology. SPC
Mesoanalysis at 1730Z shows almost the entire forecast area
within the 2.3" PWAT contour. This moist environment will set
the stage for a wet afternoon. Activity observed this morning
across the Charleston Metro area has likely all but ended the
heavy rain threat, with this afternoon's activity focusing more
on SE GA. This is supported by the 12Z HREF probabilities, which
show a 50% contour for >3" in 3 hours across our SE GA
counties. Given these high probabilities, the Weather Prediction
Center has upgraded a portion of the forecast area to a Slight
Risk of Excessive Rainfall today. The KCLX Radar has started to
detect showers south of I-16 in SE GA exhibiting little to no
movement. This is likely indicative of whats to come through the
afternoon as storms show little to no storm motion. While the
severe threat this afternoon is low, given forecast DCAPE values
of only around 300 J/kg, a strong to marginally severe storm
cannot be ruled out.

KEY MESSAGE 2: Minor to moderate coastal flooding remains possible
during the evening high tide cycles along the Charleston to Colleton
county coast through Wednesday.

High astronomical tides associated with Monday's lunar perigee and
today's New Moon will continue, with a 6.57 ft MLLW tonight and a
6.46 ft MLLW Wednesday evening in the Charleston Harbor. We will
likely see water levels peak in the 7.5-7.7 ft MLLW range this
evening with a weak northeasterly wind aiding the increasing tidal
departures. Peak water levels of 7.4-7.6 ft MLLW are forecast for
Wednesday evening's high tide. At Fort Pulaski the high tide is
forecast to peak right at 9.5 ft MLLW (Minor Flooding). A
Coastal Flood Advisory is in effect for this evening's high tide
for the entire coastline. Another Coastal Flood Advisory is
expected Wednesday evening as well. If heavy rainfall were to
occur near or during the time of the evening high tide cycles,
flooding concerns would increase as total water levels would
similarly increase.

In the absence of strong tidal departures on Thursday, coastal flood
issues are not anticipated.

KEY MESSAGE 3: Hot and humid conditions are expected to return to
the area late this week through early next week. Heat Advisories
could be needed.

Mid and upper level ridging is expected to build back across the
Southeast later this week and persist through the weekend.
Widespread low to mid 90s return to the forecast starting Thursday
and extend through the weekend and into early next week. The low-
level flow pattern around the subtropical high will help to drive
elevated dewpoints across the region as well. This combination of
highs in the low to mid 90s and dewpoints in the mid to upper 70s
will yield elevated heat indices each day, especially along the
coastal corridor. Heat index values of 105-110 degrees will be
possible along the coast each day, and Heat Advisories could be
needed.

&&

.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
KCHS/KJZI: Showers will likely linger in the vicinity of the
terminals through the afternoon, however the probability of direct
impacts to the terminals is low. A brief moment of MVFR cigs cannot
be ruled out, but overall conditions are expected to remain VFR
through the 18Z TAF period.

KSAV: Showers and thunderstorms are expected to impact the terminal
this afternoon and the 18Z TAF features a TEMPO group from 21 to 24
Z tonight to account for this. Thereafter, prevailing VFR through
the remainder of the 18Z TAF period.

Extended Aviation Outlook: Shower and thunderstorm coverage is
expected to diminish across the region beginning Wednesday evening.
Low chances of thunderstorm impacts are expected through the
weekend.

&&

.MARINE...
Tonight through Sunday: Quiet conditions with relatively light flow
and seas around 2 feet will prevail across the local waters through
Wednesday night as a weak boundary sits in the vicinity. By
Thursday, this boundary will wash out and the subtropical high to
the east will increasingly take control. This change will bring
southwest flow to the region, turning more southerly each afternoon
and evening with the sea breeze. Winds will be stronger during this
time, with 10-15 knots and gusts up to 20 knots along the land/sea
interface. Over the weekend, the gradient is expected to strengthen
between an inland trough and the high to the east. This will produce
stronger southwest to south flow, with speeds getting more into the
15-20 knot range and an increasing chance of gusts up to 25 knots,
mainly for the SC coast and Charleston Harbor. We could even need
some short duration Small Craft Advisories over the weekend.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...Coastal Flood Advisory until 11 PM EDT this evening for GAZ217-
     219-239-241.
SC...Coastal Flood Advisory until 11 PM EDT this evening for
