Fog Affecting Parts of Oregon and Washington
Special Weather Statements are highlighting areas of fog across portions of Oregon and Washington on October 5, 2026.
Fog is affecting several distinct areas, including the Pacific coast and inland valleys. Visibility can change quickly, particularly during the morning hours and around waterways and low-lying locations.
The affected regions include:
- 🌊 Oregon and Washington coasts
- 🌫️ Southern Willamette Valley
- 🌫️ Northern and Central Willamette Valley
- 🌫️ Lower Columbia Valley
- 🌫️ Cowlitz Valley
🌊 Fog Along the Oregon and Washington Coasts
Areas of fog are developing along portions of the Oregon and Washington coastline.
Coastal fog can produce sudden reductions in visibility for drivers traveling along coastal highways and local roads. Visibility may vary significantly over short distances as vehicles move in and out of fog banks.
Drivers should use low-beam headlights and allow additional following distance when visibility decreases.
🌫️ Fog in the Willamette Valley
Special Weather Statements are also highlighting areas of fog across the southern Willamette Valley as well as the northern and central Willamette Valley.
Fog can become especially persistent in valley locations where cool, moist air settles near the surface.
Morning commuters should be prepared for:
- Reduced visibility
- Slower travel speeds
- Wet or damp pavement
- Sudden changes in visibility
- Increased stopping distances
🌫️ Lower Columbia and Cowlitz Valleys
Additional fog is affecting the Lower Columbia and Cowlitz valleys.
Low visibility may create challenging driving conditions along major roads and highways, particularly near rivers and other low-lying areas.
Motorists should avoid using high beams in fog because reflected light can make visibility worse.
🚗 Fog Safety for Drivers
When driving through fog:
💡 Use low-beam headlights: Make your vehicle easier to see without creating excessive glare.
🚗 Slow down: Drive at a speed appropriate for the visibility you actually have.
↔️ Increase following distance: Give yourself more time to react to stopped or slowing vehicles.
⚠️ Watch for sudden visibility changes: Fog can become thicker within seconds.
🛑 Avoid unnecessary stops on roadways: If you must pull over, move completely off the roadway whenever possible.
⚠️ Essentials
🌫️ Expect reduced visibility in affected coastal and valley locations.
🚗 Slow down and increase following distance when driving through fog.
💡 Use low-beam headlights rather than high beams.
🌊 Watch for localized fog near rivers and low-lying areas.
📱 Monitor updated weather statements as conditions evolve.
Bottom Line
🌫️ Areas of fog are affecting portions of Oregon and Washington on October 5, 2026.
The fog is impacting the Oregon and Washington coasts, the southern, northern and central Willamette Valley, and the Lower Columbia and Cowlitz valleys.
The primary concern is reduced visibility, especially for motorists. Drivers should slow down, use low-beam headlights and allow extra space between vehicles until visibility improves.
