MIAMI (CBSMiami) – Karen is barely a tropical storm with an uncertain future.

At 11 p.m., the center of the storm was about 445 miles north-northeast of San Juan, Puerto Rico. It was moving to the north at 15 mph with 40 mph winds.

Tropical-storm-force winds extend outward up to 45 miles from the center.

A north- northeastward to northeastward motion with a decrease in forward speed is expected through early Friday.

Karen or its remnants are then expected to slow down and make a clockwise loop over the southwestern Atlantic into the weekend.

Little change in strength is forecast during the next several days.

There are no coastal watches or warnings in effect.

Karen is expected to produce additional rainfall amounts of 1 to 2 inches across the Virgin Islands, with isolated storm totals of 5 inches.

These rains may cause flash flooding and mudslides, especially in mountainous areas.
