The National Hurricane Center is monitoring an area in the Gulf of Mexico and two other areas in the tropical Atlantic.

The center said a broad area of low pressure could form in the Gulf by the beginning of next week.

“Some slow development of this system is possible thereafter as it moves generally westward, potentially nearing the western Gulf of Mexico coastline in about a week,” the center said.

After that, forecasters said the system could develop slowly as it moves toward the western Gulf’s coastline.

The system has a 20 percent chance of further formation in the next week, forecasters said.

In the central Atlantic, showers and thunderstorms associated with a trough of low pressure were about 750 miles west-southwest of the Cabo Verde Islands. The system is moving about 10 mph.

Another system was near the Cabo Verde Islands Wednesday afternoon. The tropical wave was generating a large area of disorganized showers and thunderstorms and is likely to move west-northwest at about 15 mph.
