Seattle, Washington – Wet highways and reduced visibility could impact drivers along I-5 and I-90 before 8 a.m. Thursday as a series of Pacific systems moves into Washington, bringing widespread rain and high-elevation snow through early next week.
According to the National Weather Service Climate Prediction Center, Washington now sits in a 60 to 70 percent above-normal precipitation zone through Tuesday, signaling a notably active stretch for the Pacific Northwest. The same 8-to-14-day outlook favors below-normal temperatures across much of the West Coast, reinforcing a cooler, unsettled pattern.
In Seattle, where average highs this time of year sit in the upper 40s, temperatures may trend several degrees cooler during passing systems, with highs in the low to mid-40s. Periods of steady rain could create ponding along I-5, Highway 99 and surface streets during heavier bursts. Tacoma and Everett are likely to see similar conditions, especially during the morning commute.
In the Cascades, snow levels are expected to hover near or above 7,000 feet during warmer periods, keeping most pass-level precipitation as rain or a rain-snow mix initially. However, accumulating snow remains likely at higher elevations, including Mount Rainier and areas above Stevens Pass, particularly overnight when temperatures dip. Gusty winds may accompany stronger fronts, reducing visibility in exposed areas along I-90.
Residents should prepare for travel delays in the mountains, secure outdoor items and monitor WSDOT updates for pass conditions. The active storm track continues into early next week, and additional advisories remain possible. Winter is not fully over in Washington, especially at elevation, as February comes to a close.
