There is a "high" chance that a broad area of low pressure off the coast of Africa will develop this week into a tropical storm or hurricane, according to the National Hurricane Center.
Located a few hundred miles south-southeast of the Cape Verde Islands, it is producing a large area of cloudiness and disorganized thunderstorms, the Hurricane Center said at 2. p.m. EDT.
"Environmental conditions are forecast to be conducive for gradual development of this disturbance during the next several days while it moves west-northwestward at about 15 mph," the Hurricane Center said.
The chance of formation through the next 48 hours was listed as "medium," or 30 percent.
