Storms sweeping across most of Washington state this weekend could bring record-breaking rainfall and possible flooding, the National Weather Service said Friday.
Forecasters issued a special weather statement Friday warning that power outages might occur because of high winds. The rain could push some rivers to flood stage by early next week.
Heavy rains could dump 4 to 8 inches in the mountains and up to 3 inches elsewhere by Monday.
At Sea-Tac Airport, forecasters said, 1.5 inches could fall Saturday. Sunday will bring just under 1 inch. Saturday’s daily record of 0.83 inches was set in 1988. Sunday’s daily record was set in 1951 at 0.92 inches.
“It’s likely we’ll break Saturday’s record,” Weather Service meteorologist John Smith said. “Sunday will be close.”
Although it has been a rainier-than-usual September, the Weather Service said it’s unlikely to be the wettest September on record, but it could rank as high as third.
By midnight Thursday, just over 3 inches of rain had accumulated this month. September’s monthly record is 5.96 inches, set in 1978.
“It’s 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 tonight. Daytime temperatures there will be in the low 40s this weekend.Stacia Glenn: 253-597-8653 stacia.glenn@ thenewstribune.com
