Autumn only began a few days ago but it is already feeling fall-like and a frost advisory has been issued for most of New Brunswick.
Environment Canada says a cold air mass will remain over the province with overnight low temperatures approaching zero in some areas.
Frost is expected to be more significant in low lying areas away from coastal waters.
Incidentally, the average first frost date in the fall is 27 September.
The low in Greater Moncton this morning was 2.8 C with patchy frost reported.
UPDATE: On Sunday morning, the temperature fell to 1.8 C.
