Storm Expected to Slide Along Eastern Seaboard
THUNDER BAY – Weather along the Eastern Seaboard of the United States is going to be impacted by Tropical Storm Arthur the first named storm of the season. By the weekend, the storm, according to the latest tracking model may be impacting Nova Scotia and then by late Sunday into Newfoundland.
Environment Canada reports, “Tropical storm Arthur east of Florida forecast to parallel the U.S. East Coast as a hurricane this week – may play a role in Atlantic Canada weather this weekend”.
The Weather Service states, “We are analysing the development of tropical storm Arthur and latest computer model forecasts to gain an early indication of how the storm may affect weather in Atlantic Canada this weekend. The tropical storm is expected to intensify to hurricane strength tonight as it moves slowly northeastward not far off the U.S. East Coast. A trough of low pressure will be moving eastward from the Great Lakes, guiding Arthur toward Atlantic Canada. The nature of the trough approaching from the Great Lakes will make all the difference in Arthur’s intensity, track and structure as it moves toward our region. Scenarios range from a direct effect with wind and rain to a well-offshore track with perhaps just rain from the trough, drawing moisture from the tropical system”.

Arthur gains strength, likely to become season’s first hurricane
