Isaias slams Philadelphia, triggers major flooding along Schuylkill River as barge wedged under bridge

At least 6 people were killed by the storm and millions were left without power

Torrential rainfall spawned by Tropical Storm Isaias has sent the main river in Philadelphia swelling to flood levels not seen in more than a century.

The tropical storm left at least six dead as it moved up the East Coast on Tuesday, downing trees and causing millions to lose power. The storm also triggered "widespread" rainfall amounts between 3 to 6 inches, including isolated amounts of up to 10 inches across the Interstate 95 corridor, according to Fox News Senior Meteorologist Janice Dean

"The storm is well out of the way but we are seeing incredible amounts of damage, including flooding reports," Dean said Wednesday on "Fox & Friends."

The Schuylkill River in the city was projected to crest early Wednesday at 15.4 feet, its highest level in more than 150 years.

The river only got to around 13.5 feet in Philadelphia early Wednesday but left significant flooding behind.

“The worst of this event is yet to come,”  Adam Thiel, Philadelphia’s fire commissioner and director of its Office of Emergency Management, said Tuesday afternoon.

The river topped its banks in low-lying Manayunk, turning bar-lined Main Street into a coffee-colored canal.

Workers were spotted out Wednesday trying to secure the barge, but officials said it was still too dangerous to move it as the river continues to rise.

Dean said that Isaias was "one of the most damaging storms" the Northeast has ever experienced.

"Over 3 million people without power because of this tropical storm, another indication it doesn't take a major hurricane to cause incredible damage," Dean added.

The storm is now well into Canada becoming post-tropical on Tuesday night. Breezy conditions will continue across the Northeast and New England on Wednesday in the storm’s wake.
