Forecasters say a storm headed for Western Washington could bring up to an inch of rain to the lowlands and 2½ feet of snow to the mountains.
The National Weather Service has issued a flood watch, winter storm watch and avalanche warning for Pierce, Thurston and King counties, among others.
The flood watch is in effect from today to Tuesday afternoon since recent rains have saturated the ground and increased river levels.
The winter storm watch is set to expire late today for mountain areas above 4,000 feet, including Mount Rainier National Park, Mount Baker Ski Area and Stevens Pass.
More than 2 feet of powder is expected above the snow level, and 2½ inches of rain could pelt the mountains below the snow line.
“We’re still having the effects of La Niña, which means cooler and wetter-than-normal conditions,” NWS meteorologist Johnny Burg said.
Last month, the region saw 6.29 inches of rain, making it the sixthwettest March on record. The wettest March was recorded in 1950 with 8.4 inches of rain.
