A winter storm with heavy snowfall and blowing snow is expected for Christmas Day. Location: the Avalon Peninsula. Total snowfall: 15 to 25 cm, with locally higher amounts possible. Maximum wind gusts: northeasterly 80 to 100 km/h shifting to northwesterly 80 km/h. Time span: early Thursday morning to Thursday afternoon. Remarks: Strong winds accompanying the snow will reduce visibility at times in blowing snow. Several hours of snow and blowing snow are expected before precipitation eventually transitions to rain or drizzle Thursday afternoon. However, some areas of the western Avalon Peninsula may not change over to rain and precipitation may remain as snow for the whole day before tapering to flurries in the evening. Additionally, a second similar system may affect a similar area for Friday night into Saturday. At this time the uncertainty on this system is moderate, but the public is advised to monitor future forecasts closely and keep it in mind when planning Holiday travel. ### Travel will likely be challenging. Winter Storm Warnings are issued when multiple types of severe winter weather (such as snow, freezing rain, wind and rain) are expected or occurring. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to NLstorm@ec.gc.ca or post reports on X using #NLwx.
