Tropical Depression 12 Becomes Tropical Storm Karen



At 5:00 a.m., EDT Tropical Depression 12 was named Tropical Storm Karen. Located 1,565 miles east of the Windward Islands, Karen is moving west-northwest at 16 mph and is expected to continue on this trajectory for the next 24 hours.

Computer forecasts show this system moving west-northwest during the next several days over very warm water and low shear, so there is a good chance this system could become a hurricane. Given the size of the cloud mass and the rich moisture surrounding the system, there is a concern this could become a very powerful tropical system by Thursday or Friday.

"If it stays north, Karen could affect shipping routes but it should not affect oil interests unless it takes a turn further west," said AccuWeather.com Expert Senior Meteorologist Dale Mohler.
