Even more hurricanes are rapidly intensifying in the Atlantic as the oceans and atmosphere warm in response to fossil fuel pollution and the global warming it causes.

Hurricane Erin exploded in strength and became a major storm in Atlantic waters just north of the Caribbean on Saturday, rapidly powering up from a tropical storm in a single day.

Erin is expected to produce areas of heavy rainfall through Sunday across the northern Leeward Islands, the Virgin Islands, and Puerto Rico, NHC said.
