Seattle wakes up under another blanket of low clouds and mid-40s temperatures Friday morning, with a wet Pacific system locked in to keep things damp through Feb. 13. Steady light rain is expected to develop by late morning and continue into Friday night, with highs near 48°F and light south winds. Plan on slower commutes and slick streets through the evening before the precipitation eases and tapers off by around midday Saturday, Feb. 14.
Afternoon Rain and How Much to Expect
Rain becomes increasingly likely as the day wears on Friday, with hourly chances climbing above 70% by midday and forecasters putting the overall shot at about 90%. New rainfall totals around the lowland neighborhoods should stay on the lighter side, in the roughly tenth- to quarter-inch range, but a persistent drizzle will keep roads wet and visibility reduced. South winds are expected to remain modest, so the main headache will be slick surfaces and soggy outdoor plans, according to NWS Seattle.
Commute And Local Impacts
Drivers should budget extra time for both the morning and evening runs, with slower trips and standing water in the usual low spots during Friday's commute. Patchy fog may add to the slowdown by trimming visibility at times. Transit riders should also allow some wiggle room; buses and light rail can be delayed when wet roads and cautious driving stack up. Anyone parking or walking close to the water should watch for puddling and splashover along the edges. For a bit more context on how this system set up, see our Feb. 12 preview.
Mountains And Passes
Snow levels drop to around 1,000–1,500 feet tonight into early next week, setting up fresh snow across the Cascades. Initial totals of 3–6 inches are possible at Snoqualmie and Stevens passes, with locally higher amounts around Mount Baker. If you are heading over the passes, expect slower conditions, possible chain requirements, and brief delays while crews plow and treat roadways. Check WSDOT advisories and cameras before you go, and carry traction devices if they will be needed.
Boaters And Marine Conditions
Boaters are urged to steer clear of exposed waters, with seas holding in the 10–16 foot range into the early weekend and Small Craft Advisories in effect for parts of the coastal and northern inland waters through tonight. Offshore swells may briefly ease Sunday into Monday before building again around midweek, so coastal outings are best timed for those calmer windows. For marine or pass planning, check the latest updates before heading out.
