Environment Canada has now issued a wind warning for the entire Niagara Region.
The weather office says strong winds that may cause damage are expected or already occurring.
A deepening low pressure system will move rapidly eastward just north of the regions overnight.
Southwest wind gusts of 90 km/h are expected for a period between about 1:00 AM and 6:00 AM early New Years morning.
Winds will shift to northwest and rapidly diminish after daybreak.
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.
