"Strong westerly winds push into Newfoundland Thursday," said Weather Network meteorologist Tyler Hamilton. "It's somewhat unusual to see a wind warning for portions of Newfoundland associated with a high pressure system rather than a low." 

"Damage to buildings, such as to roof shingles and windows, may occur. Loose objects may be tossed by the wind and cause injury or damage," said Environment Canada (EC) in a wind warning issued Thursday morning. 

Winds will ease in the evening, as a weak trough moves in bringing increased cloud cover to the province.
