WESTON, W.Va. — July 22, 2026. More than 7 inches of rain fell in about 6 hours across parts of north-central West Virginia Tuesday afternoon and evening, triggering a rare Flash Flood Emergency that the National Weather Service designated as a Particularly Dangerous Situation (PDS) — a label reserved for the most extreme and life-threatening flash flood events. Governor Patrick Morrisey declared a state of emergency across all 55 counties Tuesday night and deployed 300 National Guard soldiers to the hardest-hit areas.
The Sand Run stream in West Virginia crested at 10.63 feet, breaking the 8.3-foot record set during the 1985 floods. Interstate 79 was closed near Weston. Hundreds of calls for water rescues came in from Lewis, Randolph, and Upshur counties as homes and businesses inundated within an hour of the first rain bands arriving.
And West Virginia isn't the only front. As emergency crews work sunrise-to-sunrise in the mountains, Tropical Storm Bertha is crawling along the Gulf Coast toward a Louisiana landfall tonight, and the flash flood threat that hammered West Virginia is now sagging south into Virginia, the Carolinas, and Georgia — where the WPC is warning of 8-inch rainfall totals through Friday.
A single weather system, three simultaneous disasters
The West Virginia emergency was one piece of a much larger severe weather event. According to the New York Times, a vast weather pattern triggered flash flood warnings and tornado alerts from Kentucky all the way to New England Tuesday. The same system:
- Spawned multiple confirmed tornadoes in New Jersey — the NWS is confident one touched down near I-80 and Route 206 in Stanhope. Cincinnati to New Jersey saw a continuous line of severe storms.
- Flooded the Bronx River Parkway in Westchester County, New York, where two vehicles were submerged so deep only the roofs were visible. This was the second major flood event in the New York metro in less than a week.
- Triggered flash flood rescues across Middle Tennessee — Nashville firefighters pulled seven people from rising floodwaters overnight, and Mt. Juliet police responded to 15 flooding calls.
- Now threatens Norfolk, Virginia Beach, and eastern North Carolina with 2-inch-per-hour rainfall rates and 8-inch totals through Friday — a Level 3 of 4 High Risk for excessive rainfall from the Weather Prediction Center.
Bertha adds a second front on the Gulf Coast
While the East Coast fights flooding, Tropical Storm Bertha — the second named Atlantic storm of the 2026 season — is expected to make landfall Wednesday evening on the sparsely-populated Louisiana coast southeast of New Orleans, per the National Hurricane Center's 4 AM CDT advisory. Tropical Storm Warnings stretch from the Florida Panhandle west to Morgan City, Louisiana, including metropolitan New Orleans and Lake Pontchartrain.
Bertha's rainfall totals are more modest than the WV event — the NHC forecasts 1 to 4 inches of rain along the central to western Gulf Coast through Thursday, with isolated 6-inch amounts. But coastal flooding is the bigger concern. Storm surge warnings call for 2 to 4 feet above ground from the mouth of the Mississippi River to the Mississippi/Alabama border, and 1 to 3 feet elsewhere across the northern Gulf. Pensacola Bay already reported 2 feet of storm surge inundation Wednesday morning.
Coastal Flood Warnings are in effect for the Mississippi and Louisiana coastlines. Communities from the Florida Panhandle through Louisiana distributed sandbags Tuesday and closed beaches ahead of Bertha's arrival.
Why the Mid-Atlantic is next — and where preparation matters most
The same cold front and Gulf moisture combination that produced West Virginia's PDS event is sagging slowly south through the week, according to USA Today's briefing with NOAA WPC meteorologist Bryan Jackson. Jackson called it "quite a rainfall event for the mid-Atlantic and the Carolinas over the next few days."
Where the risk peaks over the next 72 hours:
- Hampton Roads, Virginia (Norfolk, Virginia Beach) — Wednesday into Thursday. Localized 8-inch totals possible.
- Eastern North Carolina — Wednesday through Friday, especially Roanoke Rapids and areas along the Virginia border. Level 3 of 4 High Risk zone.
- Central and eastern Georgia, Alabama, Mississippi — Thursday and Friday as the front settles further south.
- Philadelphia region — added to Flood Watch this morning in anticipation of additional heavy rainfall.
What "Flash Flood Emergency (PDS)" actually means
West Virginia's Tuesday-night warning is the highest-severity flash flood designation the NWS issues. It requires life-threatening flooding already occurring — not forecast, but observed — combined with a threat to a densely populated area or critical infrastructure. The NWS in Charleston warned: "SEEK HIGHER GROUND NOW!"
PDS Flash Flood Emergencies are extremely rare — a few times per year nationally, on average. When one is issued for your county, the safe response is to get to the highest floor of the sturdiest available structure, do not attempt to drive, and stay put until the water recedes. Most flash flood deaths happen inside vehicles.
The prep window is now — not when the water is at your door
The lesson from every event this month — the June Arthur Level 4 event on the Gulf Coast, the North American Monsoon burst last week, and now the West Virginia PDS event and Bertha's Gulf landfall — is the same: the useful preparation window is measured in hours, not minutes. West Virginia residents in Upshur County went from a routine summer afternoon to homes flooding above windowsills in the span of a few hours.
For homeowners and business owners anywhere from the Mid-Atlantic to the Gulf Coast this week:
- Check the active NWS alerts for your county right now. Our free Flood Watch tool pulls live NWS data and shows every active watch, warning, and advisory in your area.
- Stage flood barriers at every ground-level entry. StormBags store flat and dry until you need them, then hydrate with fresh water to full expansion in about 5 minutes. That deployment speed matters when a flash flood warning gives you 30 minutes of lead time.
- Move vehicles to higher ground before the storm arrives. If you live near any creek, drainage canal, or low-lying road, don't wait. Water damage to vehicles is one of the largest single categories of flash flood loss.
- Never drive through flooded roadways. Turn around, don't drown. Six inches of moving water can knock down an adult. Two feet will carry away most vehicles.
- Charge phones and battery banks now. Power outages are almost universal in PDS-level events.
