Current indications are that areas east of the Capital region are most likely to get more than 10 cm of snow and areas west of the region will get just less than 10 cm. There is still uncertainty in the strength and track of this system and areas in and west of the Capital region could still potentially see localized amounts greater than 10 cm. Also due to the uncertainty in system track, the area of freezing rain that is forecast south of the Capital region could shift northward.
On the positive side, if the freezing rain shifts northward, the threat of significant snow accumulations decreases in the Capital region.
Winter storm warnings are in effect for:
Leduc – Camrose – Wetaskiwin – Tofield – Lloydminster – Wainwright – Vermilion – and Provost with hazardous winter conditions expected.
A moisture laden low pressure system will cross into Alberta from BC late overnight. With this system snow, freezing and ice pellets can be expected as it pushes through central Alberta. The worst conditions can be expected Friday morning. Current indications are that the freezing rain and ice pellets will be south of the Yellowhead highway with heavy snow to the north. Total snowfall amounts will be in the 10 to 15 cm range.
Consider postponing non-essential travel until conditions improve. Prepare for quickly changing and deteriorating travel conditions. Surfaces such as highways, roads, walkways and parking lots will become icy, slippery and hazardous.
Snowfall warnings are in effect for:
Banff National Park – Bonnyville – St. Paul – Cold Lake – Lac La Biche – Fort Saskatchewan – Vegreville – Redwater – and Smoky Lake with total amounts of 10 to 15 cm’s expected.
An area of heavy snow is expected to move through east central Alberta on Friday. The heaviest snow fall is expected to be in and around Smoky Lake and in the southern portion of the Cold Lake forecast region. Heavy snow is expected to end by Friday afternoon. Storm total snowfall accumulations will be in the 10 to 15 cm range.
Be prepared to adjust your driving with changing road conditions. Rapidly accumulating snow could make travel difficult over some locations. Visibility may be suddenly reduced at times in heavy snow. If visibility is reduced while driving, slow down, watch for tail lights ahead and be prepared to stop.
Freezing rain warnings are in effect for:
Airdrie – Cochrane – Olds – Sundre – Drayton Valley – Devon – Rimbey – Pigeon Lake – Drumheller – Three Hills – Hanna – Coronation – Oyen – Red Deer – Ponoka – Innisfail – Stettler – Rocky Mountain House – and Caroline.
An area of freezing rain is expected to pass through central Alberta overnight and into Friday morning. The main band of freezing rain is forecast to form Friday morning near Rocky Mountain House and move eastwards affecting Wainwright by Friday afternoon. There is still some uncertainty as to where this line will form and it could shift 50 km either north or south. Some areas could potentially see up to 5 mm of ice accumulation causing significant threat to transportation corridors. Freezing rain will end from west to east by Friday afternoon.
Surfaces such as highways, roads, walkways and parking lots may become icy and slippery. Take extra care when walking or driving in affected areas. Be prepared to adjust your driving with changing road conditions. (efmb/td)
