Hurricane Erin now a Category 4 storm
Digest more
Tropical Storm Erin continues to move quickly to the west and is expected to begin strengthening and become a hurricane Aug. 14 or 15.
While Hurricane Erin will pass to the east of the U.S., we could still see impacts. Tropical storm force winds extend 200 miles from the center of the storm, as Erin continues to grow in size.
Erin has strengthened into a hurricane as it approaches Puerto Rico and the Virgin Islands, bringing heavy rains that could cause flooding and landslides.
