Seattle’s signature drizzle is about to turn into a full-fledged downpour as a series of storm systems approach the Pacific Northwest. The forecast for the next few days will be dominated by relentless rain, cold temperatures, and overcast skies, making it one of the season’s soggiest weeks.
This stormy stretch is bringing the lingering effects of La Niña back to the Emerald City, so don’t expect spring to arrive anytime soon.
Rain is expected almost every day, so residents should plan for wet commutes, slick roads, and chilly winds. Sunday appears to be the wettest day of the week, so don’t expect much relief until then. If you were hoping for a break from the rain, you might have to wait a while.
What’s Causing This Wet and Cold Weather?
A series of low-pressure systems moving in from the Pacific Ocean are expected to keep Seattle in a cycle of clouds, rain, and cool breezes.
La Niña has cooled Pacific waters and caused storms in the Pacific Northwest, contributing to the extended wet pattern. As a result, Seattle is receiving more rain than usual in March, with only brief dry spells between showers.
Those hoping for spring sunshine may need to be patient. Until these storm systems weaken, Seattle will remain cool, damp, and overcast.
