Meteorologists are tracking another recently formed tropical storm, Danny, which could strengthen into a hurricane and affect Atlantic Canada by the weekend.

The U.S. National Hurricane Center said Wednesday that as of 5 p.m. ET, Danny was 625 kilometres east of Nassau, Bahamas, and about 1,185 kilometres south-southeast of Cape Hatteras, N.C. The storm was reported moving toward the west-northwest at 19 km/h.

Danny had maximum sustained winds of 75 km/h.

Hurricane forecasters characterized Danny as "poorly organized," and said there is still great uncertainty about the storm's possible course. Predictions of the storm's possible path indicate it could eventually touch Cape Cod before reaching Atlantic Canada.

Staff at the Canadian Hurricane Centre said Danny has about a 40 per cent chance of becoming a hurricane, albeit a weak one. Danny is the fourth named Atlantic storm of the 2009 hurricane season.

Hurricane Bill hit Nova Scotia on Aug. 23 with high winds, heavy rain and dangerous surf. The storm knocked out power to thousands of Nova Scotia homes and business. Bill reached Newfoundland late that day, blasting the province's south coast with winds of 70 km/h and gusts to 100 km/h.
