MACKINAC ISLAND, MI – A Frost Advisory has been issued for Mackinac Island, Bois Blanc Island, and Beaver Island, with forecasters warning of temperatures dropping to around 33°F overnight into Thursday morning, according to the National Weather Service in Gaylord.
Frost Advisory Details
The advisory is in effect from midnight to 9 a.m. EDT Thursday, as calm winds and clearing skies create ideal conditions for frost to form on exposed surfaces. While these northern Lake Michigan islands typically experience some coastal moderation, even brief dips near freezing could damage tender vegetation if left uncovered.
Precautions for Residents and Visitors
The weather service recommends that residents and visitors:
- Cover outdoor plants and flowers or move them indoors
- Be cautious of frost-covered decks and vehicles, particularly for early ferry operators and marina workers
Taking these precautions can help prevent frost-related damage to gardens and property.
Thursday Weather Outlook
While Thursday morning starts cold, sunshine and light winds will allow temperatures to warm into the upper 50s by afternoon. The overall trend for the weekend is expected to be warmer and mostly dry, as a ridge of high pressure builds over the Great Lakes, bringing more typical mid-October conditions.
