Gig Harbor Forecast: Atmospheric River Brings Flooding Concerns

GIG HARBOR, WA — The wettest weather of the week is forecast to arrive Saturday afternoon, bringing along the potential for widespread river flooding in Western Washington through the weekend.

According to the National Weather Service, moderate to heavy rain may cause sharp rises on several rivers and increase the risk of landslides, while wind gusts could spur localized power outages.

A flood watch will be in effect across the region between Saturday morning and Sunday evening, including in King, Pierce, Snohomish, Lewis, Thurston, Clallam, Grays Habor, Jefferson, Mason, Skagit and Whatcom counties.

The heaviest precipitation is likely between Saturday afternoon and Sunday morning, and warmer air and rising snow levels could significant rain over the mountains. By Sunday morning, areas around Seattle and Tacoma could see 2-3 inches of rain, while portions of the coast and the passes may log up to 6 inches.

As a result of that rain, a flood watch has been issued for Pierce County from Saturday afternoon through early Sunday morning. During a flood watch the National Weather Service recommends that residents stay away from fast-running rivers or risk being swept away.

Forecasters expect a third frontal system to arrive Monday, promising more breezy conditions and another round of rain. Tuesday and Wednesday are poised to welcome back the sunshine, as afternoon temperatures dip back down to the mid-40s.

Here is the 5-day weather outlook in Gig Harbor:

Saturday: 51°/45° (Rain after 2 p.m.)
Sunday: 52°/44° (Rain likely)
Monday: 52°/37° (Rain)
