Weather Alerts
yellow watch - winter storm - in effect
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.
