MIAMI — Hurricane Irene maintained its strength Monday as it spun eastward into colder waters of the open northern Atlantic, forecasters said.
The Category 1 hurricane, with top sustained winds of 90 mph, was moving east at 14 mph, according to the National Hurricane Center in Miami. Weakening was expected to begin by late Tuesday, with a return to an east-northeast track, forecasters said.
Irene reached hurricane strength Sunday but turned away from the U.S. mainland, a threat only to marine interests. At 11 p.m. ET, Irene was about 910 miles southwest of Cape Race, Newfoundland.
Only two or three named storms normally develop by this time in the Atlantic hurricane season, which began June 1 and ends Nov. 30. Irene, the ninth of the 2005 season, developed Aug. 7, weakened to a tropical depression and then regained tropical storm strength Wednesday.
