Moisture-amplified storm to blast the East Coast with rain, winds

An expansive spring storm will churn its way across Eastern Canada this week, with effects sweeping across Atlantic Canada Tuesday and Wednesday. The region will be dealing with rain as it is on the warm side of the storm, with lots of it expected -- anywhere from 30-60 mm, depending on locale. The rain may lead to localized flooding, and with the expected intense wind gusts up to 100 km/h in some areas, power outages are also possible. More on what you can expect heading into the new week, below.

TUESDAY: MARITIMES DEAL WITH HEAVY RAIN AND A WINTRY MIX

Precipitation will begin to push into the Maritimes early Tuesday morning, leading to a soggy morning commute for southern sections of Nova Scotia and New Brunswick. Colder air up north will allow much of the precipitation to fall as snow or a wintry mix across northern New Brunswick and the Gaspesie into the day on Tuesday.

Heavy rain will continue to spread over the Maritimes through the day on Tuesday. Tropical moisture pumped north by an atmospheric river will help to juice rainfall totals across the region, with the potential for 30-50 mm of rain across southern Nova Scotia and southwestern New Brunswick by the end of the storm.

The slug of precipitation will be accompanied by strong winds as the system moves through the region. Gusts of 60-100 km/h will be common across the Maritimes, especially for coastal areas. Given the combination of gusty winds and rain loosening the soil, watch out for the potential for downed trees and power lines during the strongest winds. There is also the risk of localized flooding.

Environment and Climate Change Canada (ECCC) issued special weather statements and wind warnings for the southern halves of Nova Scotia and New Brunswick, as well as Newfoundland, ahead of the rain and wind.

Thankfully, this soggy system won’t stick around for too long. The precipitation will clear away from the Maritimes Tuesday overnight, with only some scattered showers lingering across eastern Nova Scotia and P.E.I. on Wednesday morning.

There will also be large waves and pounding surf along the Atlantic Coast Tuesday overnight accompanying the strong southeasterly winds.

WEDNESDAY: RAIN TARGETS NEWFOUNDLAND NEXT

Our dynamic low-pressure system will pull to the north into the day on Wednesday, affording Newfoundland the opportunity to get in on the action.

Precipitation will push in Tuesday overnight, with a chance of it starting out as freezing rain and ice pellets for western regions before changing to rain Wednesday morning.

A period of rain and gusty winds will then sweep farther across the island during the day on Wednesday, making the day more useful for curling up with a good book than traveling anywhere farther than to take out the trash.

Rainfall amounts could hit 40-60 mm for southwestern Newfoundland, with 30-50 mm in surrounding regions. Considerably less for inland, northern and southern areas.

THROUGH THE WEEKEND: CALMER AND SEASONABLE

Calmer conditions will prevail behind the system. Seasonable temperatures and fair conditions should reign across the Maritimes through the end of the week. We’ll watch the potential for some unsettled weather to return in time for the weekend.
