As the Bay Area welcomes the early signs of fall with a camaraderie of crisp air and turning leaves, the National Weather Service has issued a Dense Fog Advisory effective until 10 AM PDT Saturday. Commuters should anticipate reduced visibility this morning with patches of dense fog affecting major roadways and pose potential hazards for the early weekend hustle.
Particularly, areas most affected include the Willamette Valley, Greater Portland and Vancouver Metro, and the Lower Columbia and Cowlitz River Valleys. Dense fog descending upon these locales typically mean visibility is reduced to a quarter mile or less, making the morning drive feel like navigating through a swath of cotton. Fog will be most prevalent along rivers and lakes, and "visibility one quarter mile or less in areas of dense fog," has been reported by the NWS.
For those making their way outside, the NWS advises caution—slow down, allow for greater distances between vehicles, and remain vigilant of your surroundings. The forecast suggests partly sunny skies following the fog's lift, with the day reaching a comfortable high near 70 degrees.
Looking ahead into the night, expect mostly clear skies and a low around 49. The NWS points out that the northwest wind will slow to a whisper after midnight, giving way to a serene, if not eerily still, evening. For outdoors enthusiasts, the outlook is promising following the fog's retreat, with sunshine dominating the weekend forecast.
Despite these tranquil conditions, the presence of such heavy fog carries implications for those making their morning journeys. The NWS recommends, "If driving, slow down and leave plenty of distance ahead of you." In the spirit of safety, pedestrians and cyclists should not forsake visibility for style, donning bright or reflective clothing in efforts to catch the eye of motorists. It's not just a style choice; it's a beacon of precaution in the waning visibility.
Clearer skies are expected to persist deep into next week, with temperatures maintaining the gentle embrace of early fall. Yet, Tuesday might see a slight turn as chances of rain enter the forecast, however, with just a 20 percent possibility. Whether or not these rains come to pass, the climate of the Pacific Northwest continues to bear witness to the shifting paradigms of the season—each day a testament to the region's generous range of elemental expression.
