A winter storm that will hit Newfoundland, beginning this afternoon, is expected to bring a mixed bag of weather to various regions of the province.
The central and western regions of the province are expected to receive the highest accumulations of snowfall today, with the snow this afternoon turning to freezing rain and then rain tonight on the Avalon Peninsula and back to snow Saturday.
Snow, ice pellets, rain, then back to snow for St. John's, Avalon North
The Environment Canada forecast for St. John’s and Avalon Peninsula North is for a wintry mix of weather.
It says snow and strong easterly winds are forecast to spread across the Avalon Peninsula this afternoon resulting in a few hours of reduced visibilities in blowing snow this evening. The snow will then change through ice pellets and freezing rain to rain as temperatures rise well above 0 Celsius tonight.
Environment Canada says current guidance suggests near 10 cm of snow can be expected before the changeover, followed by a “potentially significant period of freezing precipitation.” Rainfall amounts are forecast to range from 15 to 25 mm with the possibility of higher totals in some areas. The rain will ease to showers or periods of drizzle before Saturday morning.
On Saturday, periods of snow, strong winds and blowing snow are forecast to redevelop as temperatures fall to below freezing once again.
Rainfall warning for southern Avalon
A rainfall warning is in effect for the southeast and southwest Avalon Peninsula.
The weather office says snow is forecast to develop on the southern Avalon Peninsula this afternoon, but will change through ice pellets and freezing rain to rain this evening. Current indications suggest total rainfall amounts will exceed 30 mm in some areas.
Environment Canada cautions the frozen ground has a reduced ability to absorb this rainfall. Localized flooding in low-lying areas is possible. The rain is expected to ease to showers or periods of drizzle overnight tonight.
Freezing rain warning for Burin Peninsula after 10-15 cm of snow
The Burin Peninsula is expected to get about 10-15 cm of snow, with blowing snow this afternoon that will spread to the Bonavista Peninsula tonight. A freezing rain warning is in effect for the Burin Peninsula tonight, with a changeover from snow to ice pellets and freeing rain.
Blizzard, freezing rain warnings for Bonavista Peninsula
Environment Canada has issued blizzard, freezing rain and wind warnings for the Bonavista Peninsula. It says snowfall accumulations may exceed 30 cm in some areas on the peninsula by Saturday morning and wind gusts could read 110 lm/h along the coast, creating blizzard conditions.
Blizzard warnings for central and western Newfoundland
Blizzard warnings are also in effect for much of central and western Newfoundland, including Gander, Grand Falls-Windsor, Corner Brook and Channel-Port aux Basques. Environment Canada says up to 30 cm of snow is expected in central regions today into Satruday and 20 to 25 cm of snow in western regions of the province. High wind gusts up to 110 km/h are also in the forecast for these areas.
Environment Canada says travel is expected to be hazardous due to reduced visibility in these areas. Blowing snow advisories have been issued for the Northern Peninsula. Environment Canada says snow and strong winds will develop overnight tonight on the Northern Peninsula, resulting in an extended period of reduced visibilities in blowing snow. Conditions will slowly improve Saturday afternoon as the snow tapers and winds ease.
Travel is expected to be hazardous due to reduced visibility in some locations. Be prepared to adjust your driving with changing road conditions.
