MIAMI (AP) - Growing slightly stronger with top sustained winds of 140 mph, Hurricane Gert spun in the Atlantic Friday on a track forecasters said could take it toward Bermuda early next week - but away from the East Coast. Gert - which became the fourth Category 4 hurricane of the Atlantic season with 145 mph winds on Thursday - was about 1,040 miles south-southeast of Bermuda at 5 a.m. ET Friday. Gert could pose a threat to Bermuda by late Sunday or Monday, Brown said. The hurricane was about 400 miles wide with a distinct eye and could widen as the storm enters the same atmospheric conditions of weak upper-level winds and warm ocean temperatures that produced Hurricane Floyd.
