Tropical Depression 6 to bypass eastern US, strike Canada with rain, gusty winds by late week

By Brett Rathbun, AccuWeather meteorologist

While the East Coast will see minimal impacts from Tropical DepressionSix, the same cannot be promised for parts of southeastern Canada by the end of the week.

The tropical feature AccuWeather meteorologists were tracking for several days across the southeastern United States became Tropical Depression Six across the open waters of the western Atlantic Ocean on Monday.

Further strengthening to Tropical Storm Erin is expected and can occur at any time through the middle of this week.

A general north to northeastward track will keep this system and its rainfall away from most of the Eastern Seaboard through midweek.

However, rough surf and rip currents will continue to batter coastal communities from Cape Hatteras, North Carolina, to Atlantic City, New Jersey.

"Minor coastal flooding and/or beach erosion can occur as well," AccuWeather Meteorologist Ryan Adamson said.

These coastal issues will creep northward to parts of the Northeast and Atlantic Canada from mid- to late week.

Cruise and shipping interests along the East coast will want to monitor the path of this system and consider finding an alternate route, if able.

A non-tropical storm system pushing across the Northeast on Wednesdaywill aid in this system not making a direct landfall to the United States.

"However, rain from the tropical system could be drawn northward and into the non-tropical storm across part of New England," according to AccuWeather Senior Meteorologist Alex Sosnowski.

"The extent of which this happens is debatable, but there may be a brief period of gusty winds on Cap Cod, Massachusetts and the nearby islands that is more related to the tropical system," Sosnowski said.

Expect rip currents and rough seas to spread northward across New England during the middle of this week and Atlantic Canada during the latter part of this week.

The tropical storm is forecast to approach the Maritime Provinces of Canada, as well as Newfoundland during Thursday and Friday.

Rainfall amounts can average 0.50 to 1.50 inches (12-38 mm) from Nova Scotia to Prince Edward Island and Newfoundland, with locally higher amounts. In addition to rain, wind gusts can approach 50 mph (80 km/h), especially along coastal locations and in the higher elevations.

The combination of rain and wind can lead to minor delays on the road and in the air from Halifax, Nova Scotia, to Charlottetown, Prince Edward Island and Stephenville, Newfoundland.

With the fast movement of this feature, impacts will be limited to 24 hours or less in most locations.

"By Friday night, any rain or wind from this system will come to an end as it moves eastward over the open waters of the North Atlantic," Adamson said.

Because no widespread flooding or property damage is expected across Canada or the U.S., this system has been designated a <1 on the AccuWeather RealImpact™ Scale for Hurricanes.

This system will depart in time for a generally dry Labor Day weekend from New England to southeastern Canada. The same cannot be said for the southeastern United States, pending the future track of Tropical Storm Dorian.
