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

Hurricane Erin will continue to strengthen as it approaches the Leeward Island and Puerto Rico, where it will threaten with tropical downpours, pounding surf and strong winds.

The rain and winds from the outer bands of the storm left about 147,000 customers without power Sunday morning in Puerto Rico, according to Luma Energy, a private company that oversees the transmission and distribution of power on the island. The weather canceled more than 20 flights, officials said.

Erin is forecast to become a major Category 3 storm late this weekend and pass some 200 miles north of Puerto Rico.
