National Weather Service is reporting a record-breaking 2.16 inches of rainfall in the last 24 hours, and has issued winter storm advisories and flood warnings for parts of the Puget Sound region. Heavy rains in the area are posing a number of potential hazards, from mudslides to highway closures.
Commuters are being urged to check their routes as rain continues to fall. Sound Transit's northbound Sounder service from Seattle to Everett has been canceled for Monday evening. North Cascades Highway is temporarily closed due to heavy snow and avalanche danger.
Deborah Wang spoke Sarah Miller with Seattle Public Utilities on Monday afternoon about the emerging problem of standing drainage water.
"With 80,000 drains in the city of Seattle, we can't be everywhere. We do clean the drains regularly," Miller explained. "However, when the trees drop their leaves, that happens in a relatively compressed period of time. Much as we get out there to clean the drains throughout the year this problem is exacerbated because the leaves drop at the beginning of November and then plug those drainage outlets."
Miller has been urging Seattle residents to adopt their local drains, to clear them of leaves and debris.
UPDATE at 5:00 p.m. on November 19:
Amtrak's Cascades passenger train service between Seattle and Vancouver, British Columbia, has been temporarily canceled. A 48-hour moratorium due to mudslide danger was issued Monday afternoon and may be lifted by Wednesday. Amtrak Cascades announces cancelations and disruptions through their Twitter feed.
