With up to a foot of rain possibly falling in the Mount Rainier area this weekend, the National Weather Service issued a flood watch Thursday.
The watch covers Pierce, King and Thurston counties, among others, and is in place from Friday through Sunday afternoon.
Heavy rainfall is on the way and Weather Service forecasters were concerned about rising river flows.
Some forecast models predicted four to eight inches of rainfall in the mountains within a 48-hour period ending Saturday, the Weather Service said.
“These amounts could cause more serious flooding for rivers flowing off Mount Rainier,” according to the flood watch.
In November, flooding near Kautz Creek forced Mount Rainier National Park to close the Nisqually entrance and remove staff members and guests at Longmire National Park Inn.
The Paradise area of Mount Rainier gets an average of 126 inches of rain annually.
High temperatures Friday and Saturday were expected to be 55 to 60 degrees with winds gusting up to 21 mph.
Friday could bring a quarter- to a half-inch of rain. Saturday was expected to see one-half inch to three-quarters of an inch of precipitation.
The forecast was more severe for higher-elevation places such as Paradise in the national park.
Daytime highs were forecast to be in the mid-40s with winds up to 45 mph and several inches of rain possible, according to the Weather Service.
