It might be July but a frost warning has been issued for parts of northwestern New Brunswick.

Environment Canada says temperatures will drop to 7 C but will dip to 2 C in low lying areas.

Those areas include the regions of Edmundston and Madawaska County, Campbellton and Restigouche County, Grand Falls and Victoria County, and Mount Carleton - Renous Highway.

"Frost may damage some crops in frost-prone areas," the national weather service said in a statement.

Environment Canada advises people to cover up plants, especially those in frost-prone areas.
