National Weather Service Wilmington NC
554 PM EDT Fri Aug 21 2026

The National Weather Service in Wilmington has extended the

* Flash Flood Warning for...
  West Central Columbus County in southeastern North Carolina...

* Until 715 PM EDT.

* At 554 PM EDT, Doppler radar indicated thunderstorms producing
  heavy rain across the warned area. Between 2 and 4 inches of rain
  have fallen. Additional rainfall amounts of 0.5 to 1 inch are
  possible in the warned area. Flash flooding is ongoing or expected
  to begin shortly.

  HAZARD...Flash flooding caused by thunderstorms.

  SOURCE...Radar indicated.

  IMPACT...Flash flooding of small creeks and streams, urban areas,
           highways, streets and underpasses as well as other poor
           drainage and low-lying areas.

* Some locations that will experience flash flooding include...
  Whiteville, Chadbourn, Southeastern Community College, Williams,
  Sidney, Clarendon, Redbug, Hallsboro, Brunswick and Cerro Gordo.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Dangerous flooding from heavy rainfall can be expected, especially
near poor drainage areas and other flood prone locations. It is
harder to recognize flood dangers at night, as it will be difficult
to determine the depth of the water. Roads may be damaged or washed
away. Most flood deaths occur in vehicles. If flooding is observed,
then turn around, don't drown.

Area Forecast Discussion
National Weather Service Wilmington NC
301 PM EDT Fri Aug 21 2026

.WHAT HAS CHANGED...
All sections have been updated with no significant changes to the
previous forecast. A Severe Thunderstorm Watch has recently been
issued for all of SE NC and NE SC, with the main hazard being
damaging wind gusts of 58+ mph.

&&

.KEY MESSAGES...
1) Heat Advisory for mainly coastal counties with the expectation
for showers, storms, and/or cloud cover to reduce temperatures by
mid-late afternoon.

2) Isolated severe storms and flash flooding possible today through
tonight.

3) Near-normal temperatures expected in the long-term with low rain
chances for Sunday/Monday before increasing midweek.

&&

.DISCUSSION...
KEY MESSAGE 1...Dangerous heat continues today closer to the coast.

Although increasing showers/storms/clouds will keep temperatures and
heat indices lower in some spots we will keep the Heat Advisory up
for at least a few more hours for heat indices generally in the 105-
109 degree range.

KEY MESSAGE 2...Isolated severe storms and flash flooding possible
into tonight, with a low risk for flash flooding continuing on
Saturday.

A trough in the jet stream and attendant cold front progressing
eastward into the Carolinas will yield scattered to numerous showers
and thunderstorms into this evening. A Severe Thunderstorm Watch has
recently been issued for mainly the risk of damaging wind gusts,
although large hail and a tornado can't completely be ruled out.
Moderate to strong instability, steep low-level lapse rates, and
anomalously high precipitable water values (~2"+) will all
contributing to a wet microburst threat. Frequent lightning and very
heavy rainfall are also expected with isolated flash flooding
possible, especially inland from the coast where storms move over
the same areas for an extended period. A low flood risk will
continue into Saturday, mainly near/east of I-95 and in areas that
pick up a good deal of rain today/tonight.

KEY MESSAGE 3...Near-normal temperatures expected starting this
weekend with low rain chances Sunday/Monday before increasing mid
week.

Scattered showers and thunderstorms will remain possible through
Saturday night as a cold front stalls just west of or over the
forecast area while impulses aloft continue to move through the
broader trough in the jet stream. A period of mostly dry weather
appears likely on Sunday and Monday as the front is shoved offshore.
However, as the flow aloft becomes westerly to northwesterly around
midweek, additional impulses and waves of low pressure are poised to
bring periods of showers and thunderstorms from Tuesday onward, with
the best chances for more widespread rain currently focused on
Thursday. Of course, given this is multiple days away, the chances
for rain will likely fluctuate in the coming days as smaller-scale
details are worked out.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
18Z Fri thru 18Z Sat: A stalling front will bring scattered to
numerous showers/storms across the area into this eve, with some
rain lingering overnight into Sat, mainly near the coast. A severe
wind gust (~50 kts) and hail up to quarter size is possible in the
strongest storms thru early to mid evening. Also, expect a low
to moderate risk for cig/vsby restrictions late tonight into Sat
morning.

18Z Sat thru Tue: Mostly VFR expected outside low to moderate risk
for cig/vsby restrictions late Sat night/early Sun, mainly inland at
KLBT/KFLO. Scattered to numerous showers/thunderstorms will continue
Saturday afternoon/evening, especially near the coast. Low risk for
restrictions from showers/storms Sun/Mon with a bit better risk Tue,
especially near the coast.

&&

.MARINE...
Today through Tuesday... Expect generally south to southwest winds
to prevail through the period as an approaching cold front stalls
near the coast. No headlines are expected as winds peak around 15-20
kts over Saturday night and wave heights stay around 3 ft or less
within 20 nmi and up to 4 ft in the 20-60 nmi zones, highest this
weekend.

The biggest marine impact will likely be from increasing coverage of
showers and thunderstorms beginning this evening and continuing
through the weekend as a front stalls near the coast. There will
likely be several rounds of storms, accompanied by reduced
visibility and possible gusty winds.

&&

.ILM WATCHES/WARNINGS/ADVISORIES...
NC...Heat Advisory until 8 PM EDT this evening for NCZ099-105>110.
SC...Heat Advisory until 8 PM EDT this evening for SCZ054>056-058-
     059.
MARINE...None.
