Risk of outages and poor travel as winds and snow pick up on Friday
Southern Ontario experienced rain through Thursday night, with temperatures in the mid to upper single digits. Rain continues across eastern Ontario, including Ottawa, Friday morning before transitioning to mixed precipitation and snow from west to east throughout the day.
Strong winds will intensify as a cold front sweeps through. Widespread gusts of 60-80+ km/h are expected, with shoreline gusts possibly exceeding 90 km/h in the afternoon and evening.
As rain transitions to snow, widespread snow bursts along with blowing and drifting snow could impact southern and central Ontario, especially snowbelt regions.
Communities with existing snow cover are particularly vulnerable.
Lake-enhanced snow squalls are forecast to develop with west-northwesterly winds later in the day, potentially bringing 5-15 cm of new snow by Saturday morning.
Temperatures will drop rapidly from mid-single digits early Friday to wind chills that feel like the minus teens by the evening.
Residents are urged to prepare for hazardous travel conditions, icy surfaces, and potential disruptions due to high winds.
