PITTSBURGH - A total of 2.1 inches of rain fell in an hour Friday during the evening rush in Pittsburgh, said Rihaan Gangat, a meteorologist for the National Weather Service. But an earlier storm meant the region was drenched by three to four inches of rain overall, causing flash floods that killed four people.
Kimberly Griffith, 45, of Plum, and her daughters, Brenna, 12, and Mikaela, 8, were trapped in their vehicle and drowned in water that rose as high as nine feet on Washington Boulevard, which runs between Highland Park and Lincoln/Lemington. They were pronounced dead inside their car at 6:10 p.m. Friday, according to the Allegheny County Medical Examiner's Office.
