Update: Dense Fog Advisory for Foothills of the Northern Blue Mountains of Oregon

The National Weather Service has issued an updated dense fog advisory, in effect until 10 a.m., for the Foothills of the Northern Blue Mountains in Oregon. Motorists and residents in the area are urged to take extra precautions when traveling through fog-prone regions.

Visibility as low as 1/4 mile in dense fog.

Low visibility could make driving conditions hazardous. If driving, slow down, use your headlights, and leave plenty of distance ahead of you.

When a dense fog advisory is announced, it indicates the presence of widespread fog that can reduce visibility to a quarter-mile or less. Such conditions increase the risk of accidents and make travel difficult.

Recommended Safety Measures

Reduce speed and allow additional time for travel.
Use low-beam headlights to increase visibility for yourself and others.
Turn on fog lights if your vehicle is equipped with them.
Avoid using high-beam headlights, which can reflect off the fog and worsen visibility.
Maintain a safe following distance to allow time for sudden stops or traffic changes.
Use lane markings as visual guidance to stay in your lane.

Travelers should consider postponing their trips until fog conditions improve to ensure safety.
