(CNN) -- A tropical depression moving through the Atlantic Ocean will likely become a hurricane, the National Hurricane Center said Saturday, though the storm is not expected to make landfall.
The storm was relatively weak Saturday, with maximum sustained winds of 30 miles per hour, but "all reliable guidance makes the depression a hurricane within a few days," the National Hurricane Center said in a Saturday evening advisory.
Conditions ahead of the storm, known as Tropical Depression 6, are favorable for strengthening, which means it is likely to become Tropical Storm Danielle as soon as early Sunday.
"All model guidance has this as a large hurricane in the middle of the Atlantic for the middle of next week," CNN meteorologist Jacqui Jeras said. "The current forecast track has the storm staying clear of land through mid-late week."
There are no coastal watches or warnings in effect for the storm, the National Hurricane Center said Saturday.
It is too early, however, to say that the storm will definitely steer clear of the United States, forecasters said, because of possible changes in the long-range forecast.
On Saturday, the tropical depression was 580 miles southwest of the Cape Verde Islands, off the west African coast.
If the depression builds into a hurricane, it would be the second of the season. Hurricane Alex left thousands in northeastern Mexico in shelters in late June and early July.
