Sept. 3, 2004 Tropical Depression 9 was upgraded to Tropical Storm Ivan at 5 a.m. Friday, making it the ninth named storm of the 2004 hurricane season.
While forecasters on Thursday predicted it would track well south of the Virgin Islands, by Friday they changed their tune.
"We're in the cone of error," said Brian Seeley, a meteorologist at the National Weather Service in San Juan.
Tropical Storm Ivan is still far out in the Atlantic, which means forecasters can't say for certain who, if anyone, will get hit. However, Seeley said the storm is predicted to take a west to west-northwest track.
Seeley said that when storms form as far south as this one, they need watching because their track often takes them over or near the Virgin Islands.
He expects Tropical Storm Ivan to become a hurricane by Monday.
He urged Virgin Islands residents to watch this one closely, particularly since they may be focused on things other than the weather during the long Labor Day holiday.
"People could be waking up on Tuesday to see a hurricane coming their way," Seeley said.
As of 5 a.m. Friday, Tropical Storm Ivan is centered at 10 degrees north latitude and 30.7 degrees west longitude, putting it about 610 miles southwest of the Cape Verde Islands. Winds are 40 mph with gusts to 50 mph. The storm is moving west at 16 mph.
The pressure stands at 1005 millibars or 29.67 inches. Winds extend outward 60 miles from the storm's center.
