Erin, Puerto Rico and Tropical storm
Digest more
Tropical Storm Erin is approaching 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.
While a Gulf disturbance that moved into Texas on Friday seems to have run its course, Hurricane Erin in the western Atlantic intensifies.
Storms that ramp up so quickly complicate forecasting and make it harder for government agencies to plan for emergencies. Hurricane Erick, a Pacific storm that made landfall June 19 in Oaxaca, Mexico, also strengthened rapidly, doubling in intensity in less than a day.
Erin is forecast to become a major Category 3 storm late this weekend and pass some 200 miles north of Puerto Rico.
