A flood watch was in effect July 7 for several states, including Virginia, Maryland, Delaware, New Jersey and Pennsylvania. "Storm total rainfall of 2 to 4 inches, with local amounts up to 6 inches, is expected," the Weather Prediction Center said in a 5 a.m. ET update. "An elevated risk for flash flooding will continue."

As the remnants of Tropical Storm Chantal stream northward into the Tri-State Area, major weather changes are in store after a near-perfect Fourth of July weekend in New York, New Jersey and Connecticut.

Tropical cyclones typically drop large amounts of rain along and near the storm's path. The slower and more significant the storm’s size, the higher the likelihood of higher rainfall totals. Some storms can drop well over 30 inches of rainfall, like when Hurricane Harvey dropped over 60 inches near Nederland, Texas, in 2017.
