Update: warning extended to 9:45 AM EDT — new 5:43 AM EDT warning
Issued 5:43 AM EDT by the National Weather Service in Charleston, WV, until 9:45 AM EDT. The earlier 4:40 AM warning for central West Virginia (until 8:45 AM EDT) has been superseded by this updated warning for a reshaped polygon: southwestern Clay, Pocahontas, southwestern Randolph, Webster, and Nicholas counties. The flood threat is carrying forward into the morning commute.
Doppler radar indicated thunderstorms producing heavy rain across the warned area. Between 0.5 and 1.5 inches of rain have fallen, with additional rainfall amounts of 1 to 1.5 inches possible. Flash flooding is ongoing or expected to begin shortly. Hazard: flash flooding caused by thunderstorms. Impact per the alert: flash flooding of small creeks and streams, urban areas, highways, streets and underpasses, and other poor-drainage and low-lying areas. This includes Route 19 between mile markers 35 and 49.
Turn around, don’t drown when encountering flooded roads — most flood deaths occur in vehicles. If you see flooding, report it to the National Weather Service when you can do so safely: 1-800-401-9535 (toll-free).
What this means for restoration teams: the mountain-county polygon (Pocahontas, Webster, Randolph, Nicholas) means remote, limited-access communities along Route 19 and the small-creek drainages — the jobs will be interior water intrusion in homes with limited cell reach and longer dry-out equipment runs. Urban-underpass and street flooding means commercial water-intrusion work too. With up to 3 inches total possible before 9:45 AM EDT, calls will start as water recedes this morning and continue for days. Stage drying assets before the first call and moisture-map every affected room.

The National Weather Service in Charleston, WV has issued a Flash Flood Warning for central West Virginia — Braxton, Calhoun, Clay, Gilmer, Lewis, Nicholas, Roane, and Webster counties — effective until 8:45 AM EDT, Sunday, September 20, 2026. Doppler radar indicated thunderstorms producing heavy rain across the warned area, with between 0.5 and 1.5 inches already fallen and another 1 to 1.5 inches possible. Flash flooding is ongoing or expected to begin shortly.
For restoration teams, this is the exact interior-flooding scenario you see most often: water pushing into homes through low-lying entry points, saturated drywall and insulation, and the first wave of water-intrusion calls once the rain lets up. This is a live snapshot as of 5:00 AM EDT. Conditions change fast — always verify with the National Weather Service for your specific county or ZIP code.

Stay Safe This Morning
Turn around, don’t drown. When you encounter a flooded road, turn around and find another route. Most flood deaths occur in vehicles — it takes very little moving water to sweep a car off the road. Never drive through flooded roadways, and never walk through moving water.
If water enters your home:
- Stay out of standing water where electricity may be present — assume any water in the home could be energized until power is confirmed off.
- Avoid the basement until water recedes and the power is confirmed off.
- Photograph everything before cleanup begins — room by room, wide shots and close-ups. Documentation matters for insurance.
- Call a local restoration contractor early — water left sitting starts a second wave of damage (mold, warping, bacterial growth) within a day or two.
What This Means for Restoration Teams
This is the bread-and-butter water-intrusion call: flash flooding of small creeks and streams and poor-drainage areas pushes water into basements, crawl spaces, and slab foundations across Sutton, Gassaway, Flatwoods, and the surrounding towns. Expect the call pattern contractors in central WV know well:
- Interior water intrusion — ground-level entry through doors, window wells, and foundation cracks, plus water backing up through floor drains in low-lying streets.
- Saturated drywall and insulation — anything wet past the paper backing is a tear-out, not a dry-out.
- Mold risk within 24–48 hours — with temperatures mild and humidity high after a morning storm, microbial growth starts fast. Drying equipment needs to be on-site same-day.
- Low-lying commercial along Route 19 and I-79 corridors — watch for retail and storage facilities near mile markers 47–61 and 64–68 that sit in drainage paths.
The play: stage equipment now, not when the phone rings. Pre-position air movers and dehumidifiers, keep an on-call rotation through the morning, and capture address + water source + affected areas on the first call — it decides the whole job scope. On-site: photo-document before mitigation, moisture-map every affected room, and keep the homeowner’s payment responsibility clear in writing before work starts.
FEMA & Federal Assistance
If flooding damages your home or business, the FEMA Helpline is 1-800-621-3362 (7 a.m.–10 p.m. local time, 7 days a week). You can also apply at DisasterAssistance.gov, through the FEMA app, or find a recovery center at fema.gov/drc.
Basic eligibility: U.S. citizenship or qualified status, identity verification, proof of occupancy or ownership, and unmet needs not covered by insurance. Apply as soon as it is safe to do so — documentation you capture today (photos, receipts, the warning itself) supports your claim.
Looking Ahead
This warning runs until 8:45 AM EDT Sunday. When it expires, that does not mean the water is gone — small creeks and streams in these counties can crest after the rain stops, and a second round of storms over already-saturated ground would re-trigger flooding fast. Watch NWS Charleston (weather.gov/rlx) for extensions or new warnings through the morning.
Demand window note for contractors: water-intrusion calls typically start within hours of water receding and keep coming for days as people discover damage — warped flooring, musty odors, wicking up drywall. Today’s Sutton/Gassaway/Flatwoods corridor is the call map for the next 72 hours.
