Tropical Storm Isaias Rains Die Down, Heavy Winds Continue In PA

PENNSYLVANIA — Tropical Storm Isaias brought torrential rains and severe flooding to southeastern Pennsylvania Tuesday morning and into the early afternoon, leaving hundreds of thousands without power and countless roads impassable.

However, the rain began to slow and taper off in much of the region in the early afternoon, with the brunt of the storm hitting the greater Philadelphia region before noon before moving on.

According to the latest briefing from the National Weather Service, the rains will continue to taper off until they cease altogether this afternoon. The flash flood warning will expire for the region at 2:15 p.m., with a flash flood watch continuing until midnight.

Heavy winds, however, remain a threat. Tornadoes are possible for the rest of the day, and heavy, damaging gusts could continue to hit southeastern Pennsylvania into the evening.

The threat of "isolated tornadoes" is strongest during the daytime hours, the NWS said. Potential exists for wind gusts from 58 to 73 miles per hour, officials said.

The region has already seen some damage from wind alone, as a roof was ripped off a building at Doylestown Hospital Tuesday morning. More than 303,000 were without power as of 2:20 p.m.

Other potential wind impacts include sidings, windows, sheds, and garage door damages, as well as unanchored mobile home damages. Lightweight objects can become "dangerous projectiles" when gusts pick up, forecasters warn.

That's in addition to downed trees and downed wires, which can cause major power outages and block roadways, as well as be dangerous falling objects themselves.
