Puget Sound Snowstorm Upgraded: Winter Storm Warning Issued

SEATTLE, WA - The National Weather Service in Seattle has upgraded its warning about a snowstorm headed to Puget Sound. Snow totals have been increased from a few inches to 3 to 6 inches in the central Puget Sound area from Tacoma to Everett and east to North Bend.

But some forecasts were pointing to more snow - as much as 8 inches in some areas.

The weather service had issued a winter weather advisory, but upgraded it on Sunday afternoon to a winter storm warning. A winter storm warning means that severe winter weather is either expected or already in progress.

The weather service warned that travel might get dangerous over the next 24 hours.

"Significant amounts of snow are forecast that will make travel dangerous. Only travel in an emergency. If you must travel, keep an extra flashlight, food, and water in your vehicle in case of emergency," the warning said.

King County Metro issued a travel advisory on Sunday stating that transit may be delayed Monday morning.

The winter storm warning is in effect from 6 p.m. Sunday until 4 p.m. Monday.

Although the warning affects the entire Puget Sound region from Everett to the Oregon border, the weather service highlighted that the storm will especially impact the areas south of Seattle.

The snow should begin to fall around 10 p.m. Sunday, the weather service says. Snow will fall through Monday morning, which could have a major affect on the morning commute. Snow will fall off-and-on throughout the day Monday.

Some areas were already seeing snow on Sunday afternoon. Grassy areas in Enumclaw had up to an inch of snow, and there was a visible rain-snow falling mix in the Seattle area.
