MIAMI - Tropical Storm Nate added muscle Thursday as it hovered almost stationary in the Bay of Campeche off Mexico’s Gulf coast, where it was expected to bring rain and higher tides, according to The Associated Press.

Nate was one of three tropical systems churning in the Gulf and Atlantic far from U.S. shores as the remnants of Tropical Storm Lee flooded roads and highways from Maryland to New England, adding to the misery of areas still recovering from Hurricane Irene.

The U.S. National Hurricane Center in Miami said Nate had maximum sustained winds approaching 70 mph and was expected to become a hurricane by Friday. The storm was centered about 110 miles west of Campeche, Mexico, and little motion was expected overnight. But forecasters said Nate was expected to begin a slow crawl in a northerly or north-northwest direction later Friday.
