Hurricane Erin rapidly strengthened into a Category 5 storm. It is not expected to make a direct hit on the U.S. but will create dangerous surf.

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.
