It’s that time of year again. The province is monitoring the rivers for rising water levels. Officials in New Brunswick say while the day-to-day weather will be the biggest factor, it cannot predict whether flooding will be as bad as it has been in the past.

All of Nova Scotia and most of New Brunswick have been placed under weather warnings as heavy rain is expected to hit the region.

According to Environment Canada, Nova Scotia could see between 25 and 40 millimetres of rainfall through the day Saturday and overnight.

Those near the Atlantic coast could see higher amounts, up to 60 millimetres.

“Showers will become rain at times heavy later this afternoon and evening before tapering to scattered flurries or showers overnight or early Sunday morning,” read the weather warning.

“Localized flooding in low-lying areas is possible,” said the agency, adding that the frozen ground also has a reduced ability to absorb the rainfall.

The province could also see strong southerly wind gusts Saturday evening, reaching between 90 to 110 kilometres per hour.

“The strongest winds are expected to be over exposed areas, especially over eastern areas of the province.”

Brennan Allen, a Nova Scotia-based forecaster with Environment Canada, said the strong winds will be seen around Nova Scotia, but even stronger gusts will hit northern Inverness County — an area of Cape Breton where winds usually are more intense.

Environment Canada said west to northwest winds are expected to pick up Sunday morning, with gusts reaching 80 kilometres per hour.

“Damage to buildings, such as to roof shingles and windows, may occur,” the weather agency said. “Loose objects may be tossed by the wind and cause injury or damage.”

The weather warning said rain should end by the evening and transition to snow overnight.

Northwestern parts of New Brunswick are under a snowfall warning.

According to Environment Canada, snow mixed with rain will change back to snow Saturday evening. “Snow will then taper to flurries by early Sunday morning.”

The weather agency warned of possible low visibility and changing road conditions in both provinces.

In Newfoundland and Labrador, where the strongest winds are expected to intensify on Sunday morning, gusts are predicted to run from 70 kilometres per hour to over 120 kilometres per hour over much of the island and along the coasts of Labrador.

“It’s going to be a fairly prolonged event. These winds will be around for 12 to 24 hours for Newfoundland, and that’s obviously a big concern,” said Mike Vandenberg, a forecast for Environment Canada.

He said it’s more normal for wind storms in the province to last just 12 to 14 hours, but in this instance the winds will pivot from southerlies to westerlies and continue on through Sunday.

Along the south and east coasts of the province there’s potential for gusts as high as 140 kilometres per hour, said Vandenberg.

Meanwhile, Vandenberg said on the west coast of the Newfoundland there’s the potential for cold rain to turn to snow, creating blizzard conditions overnight. Even more powerful winds and heavy snowfall is expected along the Labrador coast on Sunday, he said.
