MIAMI Two weather systems are brewing in the Atlantic and the Caribbean, just in time for the most active part of the hurricane season: Mid-August to October.
Tropical Storm Erin is moving away from the Cape Verde Islands in the far eastern Atlantic, and it's expected to strengthen over the next two days.
The National Hurricane Center in Miami said Thursday afternoon that the storm's maximum sustained winds are near 40 mph.
There are no watches or warnings in effect. An earlier warning for the Cape Verde Islands has been canceled.
The storm is centered about 245 miles west-southwest of the islands and is moving west-northwest at 14 mph. CBS News meteorologist David Bernard forecasted that the system will be east of Puerto Rico by Tuesday.
The second weather system is closer to home, by the Yucaton Penninsula and Belize. Bernard forecasts it could become a tropical depression the in the next 48 hours. The National Hurricane Center said there is a 60 percent chance the system will develop into a tropical cyclone in the next five days.
