Lots of activity in the tropics Friday morning, although nothing, as yet, that qualifies as a tropical storm or even a significant threat to the U.S. mainland.

Topping the list is a strengthening storm system off the Cape Verde Islands (circled in red) in the far eastern tropical Atlantic. This region has been the nursery for many of the major storms that have eventually visited the U.S., so it gets lots of attention from forecasters.

The storm brewing there now is becoming increasingly well-organized, and is given a "high" chance - better-than-50 percent - of becoming a tropical storm in the next two days. Here is the latest on this system.   

Just to the west of that storm are the remnants of Tropical Depression 2, (circled in orange) which we have noted in earlier posts. It has degenerated, but forecasters say there remains some chance it could pull itself together in the coming days. The likelihood of that, however, is put at less than 50 percent.

Last on the list is a tropical wave between the Dominican Republic and the Bahamas that is producing lots of thunderstorms in the region, but shows little sign of getting organized. It is drifting to the west or northwest - toward Florida - but is given less than a 30-percent chance of becoming a tropical storm in the next two days.
