In the Pacific, Gilma has strengthened into a category one hurricane. Located about 1,170 km southwest of the southern end Baja California with winds sustained at 130 km/h, the storm has not triggered any coastal warnings. NOAA said Gilma isn't expected to pose a threat to land and will weaken as it moves through cooler waters.
