Alerts for: Avalon Peninsula North
5:26 AM NDT Saturday 01 November 2014
Special weather statement in effect for:
- Avalon Peninsula North
A variety of weather across Newfoundland over the next couple of days.
Forecast guidance indicates that an area of low pressure now forming off the Carolinas will intensify and as it moves northward to lie over the Gulf of St. Lawrence or Western Newfoundland on Monday. While there remains considerable uncertainty with respect to the low's track and intensity, there is more consensus with a leading system approaching late today into tonight.
Precipitation associated with this leading system will gradually spread northward across most of Newfoundland later today into tonight, reaching northernmost areas on Sunday morning. Precipitation will fall as rain over southern and eastern parts of the island, while further west and north a period of snow or ice pellets may precede the rain, especially over higher elevations. Current guidance suggests parts of the Northern Peninsula may receive snowfall amounts near 5 centimetres before the changeover, while lesser amounts are likely elsewhere.
As the main system approaches, precipitation is forecast to fall as rain over all areas on Sunday night, then taper to showers or end as the low moves northward on Monday. Total precipitation amounts are expected to be highest over southern parts of the island where current indications suggest between 30 and 50 millimetres will likely fall by Monday morning with locally higher amounts possible.
Gusty winds are also forecast to accompany the main system, starting with easterlies giving coastal gusts to 80 km/h spreading up the west coast ahead of the low on Sunday. As the low departs, a strong southwesterly flow will spread across Central and Eastern Newfoundland on Monday.
Environment Canada will continue to monitor this complex weather pattern and provide additional information as it becomes available.
