Tropical Storm Nate was meandering Thursday in the Bay of Campeche off Mexico's coast, where it was expected to bring rain and higher tides.
Meanwhile, 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.
Nate had maximum sustained winds near 45 mph (75 kph) with some strengthening forecast, according to the U.S. National Hurricane Center in Miami. A tropical storm warning was in effect for Mexico's coast from Chilitepec to Celestun.
As of 8 a.m. EDT Thursday, Nate was centered about 125 miles (200 kilometers) west of Campeche, Mexico, and was drifting southeast near 1 mph (2 kph). The hurricane center predicted an erratic eastward or northeastward motion for Nate though the day.
Farther out, Tropical Storm Maria was swirling across the Atlantic with winds near 50 mph (85 kph). A tropical storm watch was in effect for the Leeward Islands of Antigua, Barbuda, Montserrat, Nevis and St. Kitts.
