Grand Forks, ND – Patchy fog with visibility under a half mile is creating hazardous driving conditions across northwestern Minnesota early Thursday, slowing down morning commutes and increasing the risk of accidents.
According to the National Weather Service in Grand Forks, dense fog will persist through 9 a.m. across counties including Polk, Red Lake, Marshall, and Pennington. Visibility may drop suddenly over short distances, making it difficult for drivers to react in time.
Cities like Thief River Falls, Crookston, and East Grand Forks are experiencing the worst of the fog. Motorists are advised to reduce speed, use low-beam headlights, and allow extra time for travel. Officials warn that patchy fog can be especially dangerous on rural roads and open highways where visibility changes rapidly.
This morning’s fog follows a week of fluctuating temperatures and calm winds, which are common contributors to rapid fog development in spring. While no additional weather alerts are in effect beyond 9 a.m., visibility may remain variable into the mid-morning hours.
Drivers should check local traffic apps or 511 services for the latest updates. Another advisory could be issued if conditions fail to improve.
