There are no active tropical cyclones Atlantic Ocean: 2.) Showers and thunderstorms have increased and become a little better organized in association with a low pressure system located about midway between the west coast of Africa and the Lesser Antilles. Environmental conditions are expected to be somewhat conducive for development, and a tropical depression could form during the next couple of days while the low moves westward at around 10 mph over the tropical Atlantic. By the weekend, however, less favorable conditions should limit additional development. * Formation chance through 48 hours…medium…40 percent * Formation chance through 5 days…medium…40 percent  Here’s a satellite image of the Atlantic Ocean   Caribbean Sea: 1.)
