yellow watch - winter storm - in effect

Dec 24, 02:23 AM - Dec 24, 06:23 PM
Severity: Moderate Urgency: Future

A winter storm is likely for Christmas Day into Boxing Day. Location: central, northeastern and eastern Newfoundland, including the Avalon Peninsula. Time span: Early Thursday morning until overnight Thursday night. Projected snowfall: - 15 to 25 cm (southeastern Newfoundland). - 20 to 35 cm (eastern and northeastern Newfoundland). Projected maximum wind gusts: - Southeasterly to northeasterly between 60 and 80 km/h (Thursday). - Northwesterly to southwesterly between 80 and 110 km/h (Thursday night and Friday). Projected rainfall: 5 to 15 mm (mostly just the Avalon Peninsula). Blowing snow: Blowing snow will likely be less significant along the coast, and more significant inland and over higher terrain, especially along the northeast coast. Remarks: Some uncertainty remains on the exact track and strength of this system, which may lead to changes in projected amounts and winds. Travel is likely to be affected. Consider changing travel plans to before or after the storm if possible. Additionally, a second similar system may affect a similar area for Friday night into Saturday. At this time the uncertainty on this system is very high, but the public is advised to monitor future forecasts closely and keep it in mind when planning Holiday travel. ### Roads and walkways may be difficult to navigate. Winter Storm Watches are issued when hazardous winter weather conditions are possible. 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. For more information about the alerting program, please visit: https://www.canada.ca/en/services/environment/weather/severeweather/weather-alerts/colour-coded-alerts.

yellow warning - winter storm - in effect

Dec 24, 08:45 AM - Dec 25, 12:45 AM
Severity: Moderate Urgency: Expected

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. For more information about the alerting program, please visit: https://www.canada.ca/en/services/environment/weather/severeweather/weather-alerts/colour-coded-alerts.

Consider postponing non-essential travel and outdoor activities until conditions improve.
