Hurricane Erin grows into Category 4

Forecasters said Erin should begin to slowly weaken as it increased wind shear. However, it's predicted to remain a major hurricane until late next week.
Additional strengthening is expected as the storm is forecast to “remain a large and dangerous major hurricane through the middle of this week,” the National Hurricane Center said.
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 was a Category 3 hurricane Sunday morning, the National Hurricane Center said in its 8 a.m. update, with sustained winds of 125 mph, with tropical storm-force winds reaching out 205 miles.
