The warning, as of now
The National Weather Service office in Charleston, West Virginia has issued a Flash Flood Warning for parts of central and western West Virginia, effective until 10:15 AM EDT on Sunday, September 20, 2026. At 7:20 AM EDT, Doppler radar and automated rain gauges indicated thunderstorms producing heavy rain across the warned area — between 1 and 1.5 inches of rain had already fallen, with additional rainfall amounts of up to 1.5 inches possible. Flash flooding is ongoing or expected to begin shortly.
This is the exact kind of event that turns into the interior flooding jobs restoration teams see most: water through finished basements, saturated drywall, overwhelmed sump systems. This is a live snapshot as of 7:35 AM EDT — conditions change fast, so always verify with the National Weather Service for your specific county or ZIP code.

Stay safe tonight
Turn around, don’t drown when encountering flooded roads. Most flood deaths occur in vehicles — never drive through flooded roadways, and never attempt to cross a flooded underpass. Be especially cautious at night, when it is harder to recognize the dangers of flooding.
If water is entering your home: stay out of standing water where electricity may be present, avoid the basement until the water recedes and power is confirmed off, and photograph everything before cleanup begins — that documentation matters for insurance. Then call a local restoration contractor. Water left sitting starts a second wave of damage within a day.
If you can do so safely, report flooding to the National Weather Service toll-free at 800-401-9535 — those reports help forecasters update the warning.
What this means for restoration teams
This is a textbook water-intrusion setup for central West Virginia contractors. Charleston, Huntington, South Charleston, St. Albans, Dunbar, Nitro, and Barboursville all sit in the warned area — dense housing stock, finished basements, and river-adjacent commercial properties. Expect:
- Interior water intrusion from overwhelmed drainage, backed-up sewers in low-lying areas, and seepage through foundation walls as the additional 1.5 inches lands on already-saturated ground.
- Saturated drywall and insulation — wicking up walls within the first hours.
- Mold risk within 24–48 hours if drying doesn’t start promptly — warm late-summer air is a mold accelerator.
- Commercial hits along the highway corridors — flooded underpasses and low spots on I-64, I-77, and the Turnpike mean commercial properties near those interchanges take water first.
The play: stage equipment now, pre-position drying assets where they can reach Charleston and Huntington quickly, and keep an on-call rotation through the morning. On the first call, capture address, water source, and affected areas before you roll — dispatch is only as good as intake. Field discipline stays the same: photo-document before mitigation, moisture-map every affected room, and keep the homeowner’s payment responsibility clear in writing before work starts.
Water-intrusion calls typically start within hours of the water receding and keep coming for days as people discover damage — the demand tail on this one runs well into next week.
Local emergency contacts
The National Weather Service asks anyone who can do so safely to report flooding toll-free at 800-401-9535. For life-threatening emergencies, call 911. We are not listing county emergency-management numbers we cannot verify in real time — if you need them, start with your county’s emergency-management office via the state’s official site.
FEMA & federal assistance
If this event causes damage beyond what insurance covers, help is available through the Federal Emergency Management Agency:
- FEMA Helpline: 1-800-621-3362 (7 a.m.–10 p.m. local time, 7 days a week)
- Apply online 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’s safe to do so.
Looking ahead
The warning runs until 10:15 AM EDT, but the hazard doesn’t end on the clock. With 1–1.5 inches already down and another 1.5 possible, creeks and streams can crest later than the warning window, and additional rounds of thunderstorms can re-trigger flooding in the same drainage areas. Watch for NWS updates as the 10:15 AM expiry approaches — Charleston’s forecasters will extend or let it expire based on gauge readings.
For restoration teams, the real demand window opens as water recedes and homeowners find the damage: Sunday afternoon through midweek. The contractors who are already staged will be the ones answering those first calls.
