Wednesday, October 27th 2021, 9:15 pm - After a powerful hit on the U.S. East Coast, a nor'easter moving off the North American coast is delivering a glancing blow to Nova Scotia.
Just days after a record-setting 'bomb cyclone' slammed the B.C. coast, Canada's Atlantic provinces are in line for their own weather bomb, in the form of a classic nor'easter that's already slammed the U.S. Eastern Seaboard. It'll only deliver a glancing blow to Canada, but that will still mean howling winds and drenching rains for southern sections, chiefly Nova Scotia. For timing on the storm, and how much rain and wind to expect, read below.
THROUGH THURSDAY: INTENSE NOR'EASTER SET TO BRUSH MARITIMES WITH BLUSTERY WINDS AND SOAKING RAIN
This system, a nor'easter, had increased potency as it moved up the U.S. Eastern Seaboard due to its status as a 'weather bomb,' meaning it experienced a drop in pressure of at least 24 millibars in 24 hours.
That typically means strong winds, and coupled with heavy rains, it had a serious impact on parts of New York and New England, with localized flooding and strong storm surge.
Fortunately for Canada, high pressure is dug in over Quebec, nudging the nor'easter's path more to the south, so a direct hit on Atlantic Canada wasn't in the cards, but it's still been bringing a fair bit of rain and strong winds, largely to Nova Scotia.
"If it is safe to do so, clear catch basins of leaves and debris to help with drainage," Environment and Climate Change Canada urges in a rainfall warning, adding that power outages are also possible at times.
Heavy downpours can also cause flash floods and water pooling on roads and localized flooding in low-lying areas is possible.
By Thursday morning, the heaviest rains will be over, with a few drops lingering as the system slowly exits the Maritimes.

BEYOND: MORE UNSETTLED WEATHER, BUT A WARM HALLOWEEN ON TAP
As this system gradually departs, the next system is set to track in for the weekend, with widespread wet and windy weather expected.
Well above seasonal temperatures will dominate, however, with a very warm Halloween expected for the Maritimes. Despite the threat for showers, daytime highs in a few spots could reach 20°C on Sunday afternoon.
Cooler temperatures will return for next week, though staying mostly near or above seasonal.
