Erin has strengthened into a hurricane as it approaches Puerto Rico and the Virgin Islands, bringing heavy rains that could cause flooding and landslides.

The storm will remain a major hurricane through the middle of the week, according to the National Hurricane Center.

Storms that ramp up so quickly complicate forecasting and make it harder for government agencies to plan for emergencies.

U.S. shores are unlikely to see a direct hit, but a strong offshore hurricane can produce massive and dangerous waves well away from its center.
