Tropical storm Arthur is expected to intensify into a hurricane tonight as it moves northeastward, prompting Environment Canada to issue a special weather statement for most of Nova Scotia
Tropical storm Arthur is expected to intensify into a hurricane tonight as it moves northeastward, prompting Environment Canada to issue a special weather statement for most of Nova Scotia.
Waters are currently warm enough to allow Arthur to intensify into a hurricane. The storm is currently located about 225 kilometres east-northeast of Orlando, Florida, and is moving northward at a speed of 11 kilometres per hour and wind speeds of about 90 km/h.
Land-based radar over Florida also shows the storm core becoming more organized with a nearly-closed eyewall.
It’s expected the first named storm of the season will merge with a cold front late this week while moving towards Atlantic Canada. The trough of low pressure from the Great Lakes will have the biggest impact on Arthur’s intensity, track and structure. Scenarios range from a direct effect on Nova Scotia, with wind and rain, to a well-offshore track with just rain from the trough, drawing moisture from the tropical system.

“With a trough of low pressure expected to eventually merge with Arthur this weekend, we expect the storm to be in a "hybrid state" when it moves through or tracks offshore,” the Canadian Hurricane Centre’s Chris Fogarty said in a technical information statement on the Environment Canada website.
The latest forecast has wind strengths the highest on July 4 at 3 p.m. By July 6, it’s expected it will be a post-tropical storm.
The warning says it’s too soon for details on wind strength, rainfall or a possible storm surge or waves.
Mariners are encouraged to remain on alert and watch for forecast updates.
