New tropical depression forms in the Caribbean

Posted at 12:47 PM, Oct 22, 2012

Tropical Depression 18 has formed in the Caribbean Sea.

The storm is about 300 miles South-Southwest of Jamaica and moving slowly southwest.

TD 18 will start moving west tonight and turn north tomorrow.

This system could strengthen to a hurricane by Wednesday. We on the East Coast need to keep a very close eye on this system.
