Tropical Storm Oscar continues to swirl in the Atlantic, but does not pose a threat to land.
Forecasters expect Oscar to transition to a tropical storm by early next week.
Forecasters at the Miami-based hurricane center say Oscar "is expected to accelerate quickly toward the northeast through the middle of the week".
A Small Craft Warning was expected to remain in effect through Tuesday night.
Oscar, the 15th named storm this season, was about 815 miles east-southeast of Bermuda and 780 miles northeast of the Northern Leeward Islands, the National Hurricane Center said in its 5 a.m. advisory. Additional strengthening is possible as well due to the warm waters and low wind shear directly above the storm.
At 500 a.m. AST (0900 UTC), the center of Hurricane Oscar was located near latitude 28.6 north, longitude 58.2 west. Oscar is moving toward the north near 13 miles per hour (20 km/h).
The Atlantic hurricane season runs from June 1 to November 30 each year, while the Eastern Pacific hurricane season runs from May 15 to November 30, the center said.
The storm had top sustained winds of 65 miles per hour.
