Caribou, Maine – Northern Maine will face its first taste of fall chill Monday night as the National Weather Service warns frost could form across much of the region. Overnight lows are expected to dip into the mid-30s, with conditions cold enough to damage unprotected gardens and sensitive plants.
According to the National Weather Service in Caribou, a Frost Advisory is in effect from 11 p.m. Monday through 8 a.m. Tuesday for Aroostook, Penobscot, Piscataquis, and Somerset counties. Communities including Caribou, Presque Isle, Millinocket, Houlton, and Fort Kent are expected to wake up to patchy frost Tuesday morning.
The early-season cold could hit home gardeners hardest. Agricultural officials recommend covering plants with sheets or moving potted flowers and vegetables indoors before sunset. Rural valleys and low-lying areas are most at risk for frost formation, where cold air settles fastest.
Motorists should also prepare for chilly early morning commutes, as frost could reduce visibility on windshields and leave roadways damp in shaded areas.
Temperatures will rebound into the 60s Tuesday afternoon, but forecasters say frost risks will return later this week as another round of overnight lows approach freezing. Residents should expect more advisories if clear, calm nights continue.
