Residents of northern Minnesota woke up to a cold surprise as temperatures dipped into the mid-30s. The National Weather Service in Duluth issued a frost advisory that stayed in effect until 9 a.m. Tuesday, warning gardeners and campers to protect sensitive plants and prepare for icy conditions outdoors.
Areas Under Frost Advisory
The advisory was mainly focused on parts of St. Louis, Cook, and Lake counties. Some of the key locations included:
Central and North St. Louis County, including Hibbing and Ely
Isabella in Lake County
Voyageurs National Park
Boundary Waters Canoe Area Wilderness
Tribal lands of the Bois Forte Band at Lake Vermilion and Nett Lake
These areas were expected to see frost, especially in low-lying and open spaces where temperatures fall more quickly overnight.
Impact on Gardeners and Campers
For gardeners, the advisory meant a serious risk of damage to plants. Sensitive flowers, vegetables, and crops can easily be harmed when frost forms. The weather service urged people to cover their plants or move them indoors to keep them safe.
Campers in the Boundary Waters and Voyageurs National Park also faced the cold. Frost was likely to coat tents, sleeping bags, and gear, making for a chilly morning start.
When Will the Chill Ease?
The frost was expected to lift after sunrise as temperatures gradually warmed through the day. However, forecasters warned that this might not be the last frost of the week. If the skies clear and winds calm again, more frost advisories could be issued.
Preparing for Cold Nights Ahead
With fall temperatures arriving earlier than some expected, residents and visitors are being reminded to stay ready for more chilly nights. Some simple tips include:
Cover or bring in plants during the night
Use extra blankets or warm sleeping bags when camping
Keep an eye on updated weather forecasts
Avoid leaving sensitive items outside overnight
Northern Minnesota’s early frost advisory is a reminder that cooler weather is setting in, even before the official arrival of autumn. Gardeners need to take precautions to protect their plants, while campers should gear up for frosty mornings in the wilderness.
Although the chill may ease after sunrise, more advisories could follow, making it important to stay alert and prepared for cold nights throughout the week.
