Rain, Wind Return to Seattle, Portland

As a bowling ball of low pressure rolls into the Pacific Northwest, rain, thunderstorms and gusty winds will break out along I-5 from Portland to Seattle on Sunday into Sunday night.

On Sunday morning, gusty winds will arrive across northwestern Oregon and eastern Washington along with periods of rain. While winds will not be all that powerful, gusts of 15-30 mph can still blow around unsecured objects such as trash cans and patio furniture.

During the afternoon, widespread showers and thunderstorms across the region will be capable of producing locally heavy rain. Rainfall will average around 0.25 of an inch in most locations, but some spots caught underneath more persistent thunderstorms could approach an inch, resulting in areas of urban and poor drainage flooding.

If you will be driving along I-5 or flying in or out of Sea-Tac Airport, be aware that some delays are possible into Sunday night as the rain and thunderstorms continue.

Those with plans to do any hiking or camping should be aware of the dangers of flash flooding and lightning. If you are close enough to a storm to hear thunder, then you are close enough to be struck by lightning.
