Rainfall warnings are in effect for the Northern Peninsula and the Straits this weekend, as post-tropical storm Arthur works its way up through Atlantic Canada.

The heaviest local rainfall amounts are set for the Northern Peninsula, the Straits, and southeastern Labrador, where accumulations could hit 50 millimetres.

According to CBC meteorologist Ryan Snoddon, Arthur will be a weaker system by the time it hits the Newfoundland and Labrador region on Saturday.

Rainfall totals in the rest of the province aren't expected to be high, although heavy downpours are possible Saturday night into Sunday, as the storm tracks through.

Winds are expected to pick up into Sunday, with gusts in the 60 to 80 kilometres per hour range on the island, which will be highest along the coasts. 

The Wreckhouse region will likely see gusts of up to 110 kilometres per hour over the weekend.

Arthur knocked out power to more than 120,000 customers in the Maritime provinces on Saturday morning. 

The storm was downgraded from its hurricane status, but homes still sustained damage, as trees came crashing down in the high winds.
