The National Hurricane Center says there is a 70 percent chance that a an area of low pressure in the Atlantic Ocean could develop into a tropical storm or hurricane by the end of this week.
"Satellite images indicate that showers and thunderstorms associated with an area of low pressure located about 1,450 miles east of the southern Windward Islands are currently limited," the Hurricane Center said just before 2 p.m. EDT Tuesday.
"This system remains well organized, however, and it could develop into a tropical depression later today or tomorrow while it moves westward or west-northwestward near 15 mph.
There is a 70 percent chance of development within the next 48 hours, and a 80 percent chance within the next five days, the Hurricane Center said.
If it becomes a tropical storm or hurricane, the system will be named Bertha.
