A series of storms will sweep across most of Washington this weekend and could bring record-breaking rainfall and possible flooding, according to the National Weather Service.
Forecasters issued a special weather statement this morning also warning that power outages might occur due to high winds.
Heavy rains could dump 4 to 8 inches in the mountains and up to 3 inches elsewhere by Monday. The rain could push some rivers to flood stage by early next week.
Record rainfall could drop Saturday at Seattle-Tacoma International Airport.
Saturdays daily record of 0.83 inches was set in 1988. Sundays daily record was set in 1951 at 0.92 inches.
"I think its likely well break Saturdays record, Weather Service meteorologist John Smith said. "Sunday will be close."
Forecasters said 1½ inches could fall in the lowlands Saturday. Sunday will bring just under an inch.
Although it has been a rainier than usual September, the Weather Service said its unlikely to be the wettest September on record. It could rank as high as the third.
By midnight Thursday, just over 3 inches of rain had accumulated this month. Septembers monthly record is 5.96 inches, set in 1978.
"Its definitely way above average," Smith said.
Temperatures in Tacoma this weekend will remain in the low 60s.
In the Paradise area of Mount Rainier National Park, rain is expected to turn to snow to night. Daytime temperatures there will be in the low 40s this weekend.
