Hurricane Erin was downgraded overnight, although it is growing in size after it spent Friday night and Saturday transforming from a tropical storm into a Category 5 hurricane, the National Hurricane Center (NHC) said in updates.

Late Saturday into early Sunday, Erin’s wind speeds were reported to have eased, leading to the downgrade to a Category 4 and then Category 3 storm, as the system passed over the northern Leeward Islands, the Virgin Islands, and Puerto Rico, according to a 2 a.m. ET update.
