Duluth, Minnesota – A frost advisory has been issued for parts of Minnesota, including South Itasca, Northern Aitkin, Carlton, South St. Louis, and Pine counties. The weather conditions are expected to begin at midnight on Sunday, September 13, 2026, and will remain in effect until 8:00 AM CDT on Monday, September 14, 2026. Residents in communities such as Grand Rapids, Duluth, Hinckley, Pine City, and Hill City should prepare for chilly conditions overnight.
According to the National Weather Service in Duluth, the cooling trend is expected to bring temperatures as low as 35 degrees during the advisory period. The combination of these low temperatures and local atmospheric conditions will result in frost formation across the impacted counties. The National Weather Service emphasizes that this cooling is significant enough to warrant public notice due to potential damage to local greenery.
The primary concern regarding this weather event is the impact on sensitive outdoor vegetation. Agricultural interests and home gardeners are advised that tender plants may be harmed or killed if they are left uncovered during the frost. The advisory serves as a precautionary measure to help residents mitigate potential losses in their gardens and outdoor landscape projects.
In response to these conditions, officials are recommending that community members take proactive steps now to protect any vulnerable plants from the cold. Covering sensitive vegetation is one of the most effective ways to prevent frost damage during these overnight hours. By acting before the onset of the cold temperatures at midnight, residents can help ensure their outdoor plants remain safe throughout the duration of the advisory period.
