What’s left of Karen drenches U.S., Atlantic Canada safe
A low pressure system, containing what is left of what once was Tropical Storm Karen, is meandering up the east coast of the United States. It has prompted Gale Warnings up and down the U.S. east coast as well as numerous other advisories, watches and warnings. Areas such as North Carolina’s Outer Banks up to Atlantic City, New Jersey and portions of New York’s Long Island are to be affected by this system.
The bad news for our friends south of the border is that a high pressure system to the north is blocking this storm system from moving anywhere fast so it is an unsettled week ahead for residents of the U.S. east coast. Forecast models are outlining up to 75 mm of rain (3 inches) with locally higher amounts possible in some locations.
Much of the anticipated beach erosion and possible coastal flooding will occur during local high tides. The blocking high pressure system to the north will help increase the pressure gradient with this storm system increasing the winds along the coast. Wind gusts could reach as high as 80 km/h on exposed coastal regions throughout the week.
The good news for us here in Canada, specifically the Atlantic Provinces, is that the high pressure system will keep the low south throughout the week and even for Thanksgiving weekend. It looks as though a stretch of pleasant fall weather is in store for Atlantic Canada right through to the holiday Monday. Temperatures are expected to be in the mid-to-high teens for the Maritimes (with cool overnight lows and the risk of frost due to clear skies).
Temperatures will be slightly on the cooler side for Newfoundland as a separate low moves to the north of the province bringing cooler temperatures and the slight chance of some showers. Only the slightest of chances for a passing shower in the Maritimes to end the week but the majority of the next five days will be dry.
