Tropical Storm Nadine holding its own

Tropical Storm Nadine isn't expected to change in intensity too much in the next several days, the National Hurricane Center in Miami said Tuesday. Nadine, with maximum sustained winds of 60 mph, is about 450 miles west-southwest of the Azores Islands, traveling on a northeasterly path at 8 mph, the center said in its 5 a.m. EDT advisory. No coastal watches or warnings were in effect. The storm is expected to stay on a northeastern course though most of the day, then shift to a more northerly path at a lower forward speed Tuesday night into Wednesday, the hurricane center said. Nadine's strength is expected to change little during the next 48 hours. Tropical storm-force winds extended 195 miles from the storm's center.
