As Hurricane Cristobal aims for Bermuda, hurricane forecasters are watching two other possible trouble spots in tropical waters.
At 2 p.m. EDT, the National Hurricane Center said an Air Force Reserve Hurricane Hunter airplane found that a weak area of low pressure over the northwestern Gulf of Mexico does not have a well-defined circulation.
"The associated thunderstorm activity has also diminished some since this morning. However, some limited development of this system is still possible before it moves inland over south Texas and northern Mexico on Thursday."
The chance of development within the next two to five days was listed at 20 percent.
A tropical wave located several hundred miles east of the Lesser Antilles was given even less of a chance of development as it produces disorganized cloudiness and showers.
There was no chance of development within the next 48 hours, and 10 percent chance within the next five days.
"However, environmental conditions could become favorable for some development by early next week in the western Caribbean Sea or southern Gulf of Mexico," the Hurricane Center said.
The Hurricane Center also said a tropical wave is forecast to move off the west coast of Africa on Friday, and "conditions appear favorable for some development thereafter while the system moves westward at 10 to 15 mph across the eastern Atlantic. Forecasters said there is a 40 percent chance of development within the next five days.
