Tropical Storm Isaac is gaining strength and organization just south of the Dominican Republic as of Friday morning, and forecasters are still expecting it to follow a northwestern path into the Gulf of Mexico.
The storm had maximum sustained winds of 60 mph as of 11 a.m.
The latest track takes it over eastern Haiti and across Cuba as it heads toward making landfall in the U.S. somewhere between New Orleans and southern Florida.

The storm is expected to pass by the Tampa Bay area, site of the Republican National Convention, early Tuesday, but the current forecast has it a few hundred miles off the coast.
AccuWeather.com's Henry Margusity is standing by predictions he has held for days that the storm will make a turn more to the north and come up the Atlantic Coast, though he recognized that is against what most models are saying at this point, writing in a blog post this morning.
Margusity's colleague, Dan Kottlowski, head of the AccuWeather.com hurricane center, agrees with the models that Isaac is much more likely to move through the Gulf of Mexico.
