An area of low pressure out in the Atlantic shows a strong chance of developing into a tropical cyclone in the next two to five days, the National Hurricane Center says.

The system being watched is about 800 miles west-southwest of the Cabo Verde Islands.

Environmental conditions are still favorable for a tropical cyclone to form within the next day or two while the low moves westward or west-northwestward at 10 to 15 mph across the tropical Atlantic, the center said.

* Formation chance through 48 hours was 70 percent.

* Formation chance through 5 days was 80 percent.

After that time, the system is expected to encounter a dryer and more stable air mass, which should be less favorable for development, forecasters said.
