Heavy rainfall continues as remnants of Ida soak Maritimes

Heavy rain from the remnants of Hurricane Ida made its way over Atlantic Canada Thursday evening.

Rainfall warnings remained in place late in the afternoon for Nova Scotia and Prince Edward Island, as well as parts of New Brunswick, Newfoundland and Quebec.There have been some power outages across the region.

Environment Canada said it expected a total rainfall of 40 to 60 millimetres throughout most of P.E.I. and Nova Scotia. Some locations in Nova Scotia could reach 100 millimetres.

But rainfall totals in P.E.I. have so far greatly exceeded expectations. CBC P.E.I. meteorologist Jay Scotland said that as of 5 p.m. AT, rain totals throughout the Island have ranged from 40 to over 90 millimetres.

Wow! Mother Nature delivering more than expected as remnant moisture from <a href="https://twitter.com/hashtag/Ida?src=hash&ref_src=twsrc%5Etfw">#Ida</a> falls over Maritimes. Unofficial rain totals in the 40-90+ mm range as of 5 p.m. ADT with more this evening before tapering off to showers overnight. Local flooding + washed out roads are big concerns. <a href="https://t.co/VbU0rkkvZ1">pic.twitter.com/VbU0rkkvZ1</a>

As per Dr. Sills thread, Nova Scotia is looking at a "non-zero tornado risk today"... meaning a tornado can't be ruled out in this environment. Stay tuned any potential updates this afternoon.<a href="https://twitter.com/hashtag/nsstorm?src=hash&ref_src=twsrc%5Etfw">#nsstorm</a> <a href="https://twitter.com/hashtag/nswx?src=hash&ref_src=twsrc%5Etfw">#nswx</a> <a href="https://t.co/yt5H0OY4Gk">https://t.co/yt5H0OY4Gk</a>

In southeastern New Brunswick, rainfall is expected to range from 40 to 70 millimetres. Western and southwestern Newfoundland can expect 30 to 60 millimetres, with the heaviest rains occurring Thursday night.

Heavy downpours could cause flash floods and water pooling on roads, and localized flooding in low-lying areas is possible. Visibility could also be an issue for drivers in the heaviest rain.

P.E.I. RCMP warned drivers to adjust their speed to the dangerous road conditions caused by the rainfall, and to turn on their headlights so they can be better seen.

Rain is coming down heavy at this hour as hurricane <a href="https://twitter.com/hashtag/Ida?src=hash&ref_src=twsrc%5Etfw">#Ida</a> moves through the region. Adjust your speeds to avoid hydroplaning and maintain safe following distance. You should also turn on your headlights so others can see you better. Cst.

The potential for hydroplaning is high because of the amount of water on roads across the region. When cars speed over rain-soaked road surfaces, the tire treads can stop displacing the water and start to slide across the surface instead.

"Prevent hydroplaning by scanning ahead for large puddles and reducing your speed, especially during heavy rain," the Insurance Bureau of Canada advises on its website. "If hydroplaning happens, don't brake â€" decelerate and drive straight."
