Tropical Storm Gordon came ashore along the central Gulf Coast on the night of September 4th.  The tropical cyclone dissipated over Missouri by the night of September 7th. Moisture from the decaying tropical system interacted with a surface low and frontal boundary, spreading widespread heavy rainfall across the region over a 3 day period and creating widespread flooding. 72 hour totals across southwest Pennsylvania from 2 inches to a little over 7 inches. Storm rainfall total for Pittsburgh ranks #2 for tropical remnants at 5.64 inches (Hurricane Ivan in 2004 still remains #1 at 5.94 inches).  Disaster declarations were made in Allegheny County (where five municipalities had already done so) and in Westmoreland County.
The U.S Small Business Administration awarded low-interest loans to qualifying victims of flooding. The money follows Governor Tom Wolf's request to SBA to declare a disaster in Westmoreland County. The disaster declaration also makes homeowners, renters, and businesses eligible for the loans in Washington, Fayette, Allegheny, and Indiana County. Low-interest loans of up to $200,000 are available to homeowners to repair or replace damaged or destroyed real estate, Wolf���s office said. Regulations permit loans of up to $40,000 to repair or replace personal property. Businesses and nonprofits can borrow up to $2 million to restore damaged or destroyed buildings, inventory, equipment and assets.
