Rain also expected across the island
Environment Canada says rainfall accumulations of 25 millimetres are expected by Wednesday morning for southwestern Newfoundland from Channel-Port aux Basques to Corner Brook.
Rain is expected to begin Tuesday night and continue into Wednesday.
The rain is the result of a low pressure system over Northern Ontario that will track northeastward across Quebec on Tuesday. A warm frontal trough associated with this low will approach southwestern Newfoundland Tuesday afternoon, bringing warming temperatures and rain to most of Newfoundland on Tuesday night.
