A Flash Flood Warning is active right now across five eastern Ohio counties, issued by the National Weather Service office in Pittsburgh, PA at 9:50 AM EDT and in effect until 12:00 PM EDT today. Doppler radar shows heavy rain continuing over the warned area, with 2 to 3 inches already on the ground and another half inch to an inch still possible — flash flooding is ongoing or expected to begin shortly. This is the exact interior-flooding scenario that keeps restoration teams busy for days: saturated basements, overwhelmed drains, and water finding every low point in older housing stock.
This is a live snapshot as of 10:00 AM EDT on Sunday, September 20. Conditions change fast — always verify with the National Weather Service for your specific county or ZIP code.
Eastern Ohio — Flash Flood Warning
The warning covers northern Belmont, northeastern Guernsey, southern Harrison, southwestern Jefferson, and southern Tuscarawas counties in Ohio, from 9:50 AM to 12:00 PM EDT. It was issued by NWS Pittsburgh PA as a radar-indicated event — meaning Doppler radar is tracking the heavy rain directly, even if gauges haven’t caught it all.
The NWS alert details:
- Hazard: Flash flooding caused by heavy rain.
- Source: Radar indicated — heavy rain continues across the warned area, mainly in Harrison and Belmont Counties.
- Rainfall so far: 2 to 3 inches have fallen. Additional amounts of 0.5 to 1 inch are possible.
- Impact: Flash flooding of small creeks and streams, urban areas, highways, streets and underpasses, as well as other poor-drainage and low-lying areas.
Locations that will experience flash flooding, per the NWS, include Martins Ferry, St. Clairsville, Freeport, Newcomerstown, Bridgeport, Antrim, Flushing, Adena, Dillonvale, Brookside, Port Washington, Mount Pleasant, Holloway, New Athens, Harrisville, Piedmont, Tippecanoe, and Gilmore.

Stay safe
Turn around, don’t drown. When you encounter a flooded road, do not drive through it — most flood deaths occur in vehicles, and it takes shockingly little water to carry a car away. This is a Sunday morning; roads you drive every day can be under water in minutes.
If water is entering your home:
- Stay out of standing water where electricity may be present — one energized outlet turns a flooded basement into a hazard zone.
- Avoid the basement until water recedes and the power is confirmed off.
- Photograph everything before cleanup. Documentation matters for insurance — adjusters need to see the damage before you start moving things around.
- Call a local restoration contractor. Water left sitting starts a second wave of damage within a day — drywall wicks it upward, and mold gets a foothold within 24 to 48 hours.
What this means for restoration teams
A radar-indicated flash flood warning on a Sunday morning is a specific kind of call volume: homeowners discovering water when they wake up, walk downstairs, or get back from errands. Two to three inches of rain falling fast means the damage profile leans toward interior water intrusion — basement seepage through foundation cracks, window-well overflow, overwhelmed sump pumps, and sheet flow across lots that pools against foundations.
In this corridor of eastern Ohio, a lot of the housing stock is older, which raises the odds on the expensive categories: saturated drywall and insulation, flooring damage that spreads as water migrates, and sewage backup in low-lying neighborhoods where combined systems surcharge. Mold risk clocks in at the standard 24–48 hour window — and the fact that many homeowners will wait until Monday to call means Sunday intake discipline is what separates a clean job from a callback.
The play for crews today:
- Stage equipment now — dehumidifiers, air movers, and extraction gear ready to roll, not still in the shop.
- Pre-position drying assets and keep an on-call rotation through the morning and into the afternoon; the water-intrusion calls typically start within hours of water receding and keep coming for days as people discover damage.
- Capture address, water source, and affected areas on the first call — that triage decides whether a truck rolls today or a ticket lands on Monday’s board.
- Field discipline: photo-document before mitigation starts, moisture-map every affected room, and keep the homeowner’s payment responsibility clear in writing before work begins.
FEMA & federal assistance
If flooding damages your home, help may be available through FEMA: the FEMA Helpline is 1-800-621-3362 (7 a.m.–10 p.m. local, 7 days a week), or apply at DisasterAssistance.gov and through the FEMA app. Recovery centers can be found at fema.gov/drc.
Basic eligibility: U.S. citizenship or qualified non-citizen 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 — don’t wait for the water to be gone before starting the paperwork.
Looking ahead
The warning expires at noon EDT today. What to watch after it lifts: creeks and streams in the warned counties can keep rising for hours after the rain stops — flooding downstream of the heaviest rain is the classic after-effect. Keep an eye on additional rounds; NWS Pittsburgh updates its outlooks regularly, and a follow-up warning is always possible if another cell trains over the same counties.
For restoration operators, the demand window is the real story: calls start within hours of water receding and stretch for days as homeowners find damage they missed on the first walkthrough. Basements checked “fine” on Sunday can show mold smell by Tuesday — a check-back call is cheap and often turns into work.
