The National Hurricane Center is monitoring two disturbances in the Atlantic—the first poised to approach the northern Leeward Islands later this week and the second near the Cabo Verde Islands—while Hurricane Erin, now a Category 3, heads away from the Caribbean.

Hurricane Erin weakened to a Category 3 hurricane on Sunday, its outer bands lashing the Virgin Islands and Puerto Rico, as forecasters warned the storm was rapidly growing in size and would gain new strength.
