Tropical Storm Nate, already dumping rain on Mexico's Gulf coast, was forecast to come ashore midday on Sunday but was not likely to strengthen into a hurricane. Nate weakened slightly overnight, the Miami-based U.S. National Hurricane Center was quoted as saying by Reuters. "Nate is running out of time to strengthen and it appears highly unlikely that it will reach hurricane strength before landfall, which is expected to occur around midday," the hurricane center said in its 5 a.m. ET (0900 GMT) advisory. The storm had maximum sustained winds of near 60 mph (95 kph) with higher gusts, and little change in strength was expected before landfall, the center added.
