Of more concern, though, is a system located 200 miles north of the northern Leeward Islands, 99L, which has a 50 percent chance of developing into a tropical cyclone over the next five days.
99L is now moving northwest and might gather strength as upper-level winds become more favorable for its development over the weekend.
Tropical Depression Eight formed Saturday evening in the Western Atlantic, the National Hurricane Center said.
Gradual strengthening is forecast during the next 48 hours, and the depression is expected to become a Tropical Storm later Sunday.More news: Gold seen topping $US1350 an ounce on US, North Korea tensions
The National Hurricane Center said Tropical Depression Eight would not threaten the USA and stay to the east. If the system goes farther west than expected, some outer rain bands may graze the North Carolina Outer Banks early this week.
The disturbance is forecast to move northwestward through the weekend and to turn northeastward - away from the USA coast - early next week. 300 miles. Increased surf and rip current risks are likely the only impacts we will feel in the East.
The hurricane center expected it to gradually strengthen over the next few days.
