Spotty Lowland Snow Creates Isolated Slick Road Hazards on Whidbey Island

Spotty lowland snow created isolated slick roads around Whidbey Island during the morning commute on Feb. 18, 2026, as a regionwide system produced mixed precipitation across parts of the Puget Sound region. Rain fell before 4 a.m. around the waters of Puget Sound near Whidbey Island and in Snohomish County, mixing with snow over colder inland areas and leaving patchy, slick surfaces on local roads.

Port Townsend, Snohomish County, and eastern King County all reported snow falling before 4 a.m., producing the spotty accumulations that complicated morning travel. Where flakes hit colder pavement, drivers encountered isolated slick spots rather than a uniform coating, increasing the risk for sudden braking or loss of traction on familiar commuter routes to and from Whidbey Island ferry terminals.

The mixed precipitation prompted local impacts: Granite Falls canceled classes because of snow, and isolated travel hazards were reported during the morning of Feb. 18. "Where snow does fall Wednesday morning, spotty accumulations and slick roads are possible, so we'll trigger a KOMO Weather Warn Day for the outside risk of hazardous driving," KOMO Meteorologist George Waldenberger wrote as the outlet activated a KOMO Weather Warn Day to highlight the driving risk.

KOMO singled out specific counties for extra caution: "Eastern King County, Snohomish, Skagit, Whatcom, and Jefferson County should be ready for slippery roads just in case." The outlet added a note of perspective: "This is the exception, however, and not the rule, as roads in many more areas will be fine to drive to work on." The original report also preserved an advisory fragment: "The advisory urged drivers to expect mixed r" which underscored the mixed nature of the precipitation that complicated early-morning conditions.

Forecasters emphasized the brief nature of the event and the need for readiness later in the day. "Despite all of this, most of the day in most spots will be on the dry side. Still, be ready Wednesday afternoon or evening for a brief bout of rain/snow/sleet. Sunbreaks will be limited," KOMO advised, signaling that evening commutes could see another short window of mixed precipitation across parts of the region.

The system was forecast to shift southward the following day. "Thursday morning, there will again be spotty lowland snow/sleet but it's most likely over Lewis and Pacific counties southward as the system producing it all passes to the south," KOMO noted. Forecasters added meteorological context: "Flow around this passing system is counterclockwise, drawing a cold batch of air in behind it on Thursday afternoon. Winds will pick up, and wind chills may drop to the 20s and teens Thursday night. It's also a dry air mass, so it should clear out the skies and brighten up the sun on an otherwise cold day."

KOMO's current conditions snapshot on its webpage showed "Cloudy" and "Now 38°" with highs later in the week of "Fri 44°" and "Sat 47°." For Whidbey Island drivers and Puget Sound commuters, the immediate takeaway was practical: expect mostly dry roads in many places but be prepared for sudden, isolated slick spots during the Feb. 18 morning commute and for colder, windier conditions with wind chills in the 20s and teens by Thursday night.
