Seattle weather: Rainy, breezy storms brewing on Sunday

SEATTLE - Pockets of heavy rain, isolated thunderstorms, higher elevation mountain snow and breezy weather are possible across Western Washington on Sunday.

Earlier this morning, Bellingham received more than two inches of rain. Starting just before 5 a.m., a landslide covered the northbound lanes of I-5 in Bellingham just north of Iowa Street.

Gusty winds also ripped through the region. This morning, gusts peaked at 40 mph in Everett, 48 mph in Hoquiam and 36 mph in Seattle. While it’ll be breezy this afternoon, winds aren’t expected to be as strong. Mostly likely, gusts will fluctuate between 20-30 mph this afternoon. 

There will be rounds of heavy downpours, potentially making driving difficult. Water levels will be rising over local rivers, but we’re not predicting river flooding right now. If any storm drains around Western Washington get clogged with leaves and heavy rain develops, there may be hyper-localized street flooding. Remember: never drive into flooded waters!

This afternoon, there could be isolated lightning strikes (especially along the coast), small hail and graupel. There will be a lesser chance for lightning in Seattle during the Hawks game, but the chance isn’t non-zero - so we need to watch conditions closely.

We hit our high temperatures before 7 a.m. today. This afternoon, temperatures will range in the mid 50s.

Late tonight to Monday, snow levels could cool down to 4,000 feet in elevation. This could trigger snowflakes falling over White and Stevens Passes, but snow totals seem unlikely in those areas (of course, that could change so stick with us). Right now, we’re forecasting between 5-10 inches of snow accumulating over the North Cascades above 4,000 feet starting tonight.

A Winter Weather Advisory is in place for the North Cascades late Sunday to Monday. (FOX 13 Seattle)

We have another chance for spotty lightning strikes on Monday (primarily over the South Sound and the coast). There could be a few cases of heavy rain as well. 

Tuesday looks mostly dry with increasing sunshine.

Hit-or-miss rain lingers for Wednesday, Thursday (Halloween!) and Friday. Saturday could offer less rain. Stay tuned! Here’s a look at your seven day forecast.
