Hurricane Gil weakened into a tropical storm in the eastern Pacific Ocean on Saturday, according to the U.S. National Hurricane Center. It was not forecast to threaten land. The Miami-based U.S. National Hurricane Center said the storm’s maximum sustained winds dropped to 65 mph.

A tropical wave was forecast to move off the west coast of Africa in the next day or two. Thereafter, some gradual development of the wave is possible during the middle to latter part of next week while it moves generally west-northwestward across the central tropical Atlantic.
