Despite changes in intensity, Erin’s size will drive dangerous surf and massive seas along much of the United States East Coast, as well as Atlantic Canada and Bermuda waters.

Hurricane Erin could 'at least double or triple in size' next week and the track has shifted south, but remains likely to turn away from the East Coast.

Hurricane Erin weakened overnight but remains a major hurricane, according to the latest advisory from the National Hurricane Center. A major hurricane is one that's a Category 3 or higher, with maximum sustained winds of at least 111 mph.
