MIAMI (AP) – Isaac strengthened into the fifth hurricane of the Atlantic season Saturday, and its winds could reach Canada early next week, forecasters said.

At 11 p.m. EDT, Isaac had top sustained winds near 80 mph, above the 74 mph threshold to become a hurricane, the National Hurricane Center in Miami said. The storm was not expected to strengthen in the next 24 hours.

Isaac should stay east of Bermuda, but Nova Scotia and Newfoundland could feel the outer edges of the storm by Monday or Tuesday, forecasters said.

The ninth named storm of the Atlantic hurricane season was centered about 285 miles east of Bermuda and moving north-northwest near 10 mph. A turn to the north was expected in the next 24 hours.

Hurricane-force winds extend 15 miles from the center, while tropical storm-force winds of at least 39 mph extended up to 105 miles from Isaac’s center.

The Atlantic hurricane season began June 1 and ends Nov. 30.
