HARRISBURG, Pa. (WHTM) -
The entire Midstate region is under a flood watch through Thursday, and some residents are preparing for isolated flooding.
"When you have an inch of rain fall and it saturates the ground, now you've got a sponge that is full," abc27 meteorologist Ryan Coyle said. "And then you get another 2, 3, 4 inches on top of that -- that's the problem."
Coyle said most areas will see 2-4 inches of rain, while some could see up to six inches.
"A lot of people know what that means for their backyard," he said.
Melissa Snyder is one of those people. She has weathered two floods during her 14 years living in Harrisburg's Shipoke neighborhood.
"You move down here knowing, it's not if it floods -- it's when. And once you've been through one, it's easier," she said.
With the river expected to crest between 17 and 19 feet, according to Coyle, Snyder said she only becomes concerned when the levels get closer to 20 feet.
"Because that half a foot makes a difference," she said.
The river has not reached the 17-foot flood stage since 2011, when Tropical Storm Lee caused evacuations throughout many sections of Harrisburg City, as well as several Midstate townships.
