Heavy rain and thunderstorms are forecast over the mountains Thursday, prompting a flash flood watch in the Cascades.

Burn scars Bolt Creek, Goat Rocks, Sourdough, Easy, Chilliwack, and Suiattle-Boulder-Toketie could also see floods, according to the National Weather Service (NWS) in Seattle.

“Potentially see some rain rates up to an inch an hour, and so that may bring some risk of debris flow on any of the burn scars that we’ve seen on our fires from the last couple years,” Samantha Borth, meteorologist with the NWS in Seattle, explained.

That flash flood watch will run until 5 a.m. Friday.

No flash floods expected in foothills

No major impact is expected in the foothills, but they could still see some showers and thunderstorms.

“We might see some showers and thunderstorms move over the area, but we’re not expecting to have, like, any flash flooding right now for those areas,” Borth said.
