While a Gulf disturbance that moved into Texas on Friday seems to have run its course, Hurricane Erin in the western Atlantic intensifies.

At 11 a.m., the center of Hurricane Erin was located about 235 miles east-northeast of San Juan, Puerto Rico, traveling west at 17 mph. Forecasters said Erin is undergoing rapid intensification and is expected to strengthen further in the coming hours.

Weather experts on the Leeward Islands, including Puerto Rico, are keeping close watch as Erin lurches toward the Caribbean and is on track to become a major hurricane.
