Bermuda prepared for what officials said could be a \"historic storm\" Friday as Tropical Storm Leslie spun its wheels in the Atlantic. At 11 a.m. EDT, Leslie was 410 miles south-southeast of Bermuda with no forward motion, the National Hurricane Center in Miami reported. The maximum sustained winds were 70 mph, making Leslie a strong tropical storm, but forecasters said the storm was expected to resume moving forward Saturday and to regain hurricane strength during the weekend. Public schools in Bermuda were closed Friday and government buildings were to close early, with Leslie predicted to reach the British territory Sunday, CNN reported. \"Leslie could be a historic storm for Bermuda as it is very large and forecast to intensify rapidly as it approaches,\" Bermuda\'s Emergency Measures Organization said in a statement this week. \"The island could experience hurricane-force winds for a sustained period of time, possibly up to two days.\" Officials in Newfoundland were preparing for the possibility Leslie could hit Wednesday, the Canadian Broadcasting Corp. said. Hurricane Igor caused extensive flooding and knocked out power for days in September 2010. Forecasters said Leslie\'s predicted track could change in the next five days, with the storm remaining out to sea and bypassing Newfoundland, but NHC forecasters said residents should not bet on that.
