Snow up to 15 centimetres is expected for the Gander central areas by tonight, and winds up to 100 km/h expected to develop in the Bonavista and southeast Avalon Peninsula areas this evening.
High waves and pounding surf are also expected to develop along parts of the northeast coast this evening.
It's currently raining in the St. John's area.
Environment Canada reports that a complex low-pressure system developing south of Newfoundland will rapidly deepen this afternoon as it passes near the Avalon Peninsula to lie offshore as an intense low-pressure system by this evening.
Snow ahead of this system has developed over central and western Newfoundland and is expected to spread to the Northern Peninsula this afternoon.
Between 10 to 15 centimetres can be expected for regions along the northeast coast and the northern peninsula east by this evening.
Winds will dramatically increase this evening over much of the island as this low pressure system continues to intensify offshore. Westerly wind gusts are expected to reach 100 km/hour this evening and persist overnight until the low moves further out to sea.
Additionally, this low will generate conditions favourable for the development of sustained snow squalls beginning late this evening and persisting into Friday along the west coast. Local snowfall amounts of 10 centimetres are expected overnight tonight and again into Friday in snowsqualls; however, the potential to exceed this amount exists. Strong westerly winds combined with these accumulations will reduce visibility in blowing snow.
