Erin became a Category 5 hurricane as of Saturday morning, packing winds over 160 miles per hour, and is passing north of the Leeward Islands and Puerto Rico Saturday evening.

Hurricane Erin is rapidly intensifying as it tracks above the northeastern Caribbean Saturday, churning up rough surf and sending rain and gusty winds to islands south of its path.

Erin has also raised concerns about wildfire risks if human-caused sparks ignite parched vegetation and strong dry winds fan the flames.
