Tornado Warning Hits Philly Area In Midst Of Storm

SOUTHEASTERN PA — A tornado warning was issued in parts of the greater Philadelphia region on Friday afternoon, with forecasters warning of the potential for extensive damage.

The warning was in place in Montgomery, Delaware, and Chester counties until noon, when it expired as the storm weakened. Residents had been urged to take cover and shelter immediately.

"Flying debris will be dangerous to those caught without shelter. Mobile homes will be damaged or destroyed," the National Weather Service said. "Damage to roofs, windows, and vehicles will occur. Tree damage is likely."

Just before noon, officials said the storm had weakened, and "no longer appears capable of producing a tornado."

"However small hail and gusty winds are still possible with this thunderstorm," the National Weather Service said. A severe thunderstorm warning remains in place for Montgomery Chester, Delaware, and Berks counties until 12:45 p.m., and a severe thunderstorm watch is in place for the whole region until 6 p.m.

The full extent of the damage from the potential tornado and straight line winds is not yet clear. Extensive straight line wind damage was seen over West Chester at 11:32 a.m., officials said. The storm was moving steadily east at 40 miles per hour that time.

Nearly half an hour later, at 11:57 a.m., severe thunderstorms were located from Green Lane to Conshohocken, heading towards Penns Grove at 45 miles per hour. At 12:19 p.m., they were moving from Dublin to Willow Grove to Paulsboro in New Jersey.

Hail of up to one inch was predicted.

During a tornado or severe thunderstorm warning warning, officials urge residents to move to the basement or an interior floor on the lowest floor of a sturdy building.

"Avoid windows. If you are outdoors, in a mobile home, or in a vehicle, move to the closest substantial shelter and protect yourself from flying debris," the National Weather Service said.
