Miami (CNN) -- Tropical Storm Philippe churned in the eastern Atlantic early Monday, posing no immediate threat to land, the National Hurricane Center reported.
The storm with its 60 mph winds was located about 545 miles (875 kilometers) west of the southernmost Cape Verde Islands and more than 1,800 miles east from the nearest Caribbean islands. No coastal watches or warnings have been posted.
The storm grew in strength over the weekend and "some strengthening is forecast through Monday before Philippe is affected by stronger upper-level winds and moves over cooler water," forecasters said.
Tropical storm-force winds of 40 mph or more extend out 70 miles from its center.
The storm is now heading northwest at around 12 mph, with a gradual turn more northward -- and a slight slowdown -- expected through Tuesday, according to the center.
