The U.S. National Hurricane Center said that Hurricane Hillary has grown into a category 4 storm with sustained winds of 145 mph. The latest forecast track shows that it could hit southern California Sunday. Currently the center of the hurricane is about 400 miles south of Los Cabos, Mexico, which is on the southern tip of the Baja Peninsula. Although the storm is expected to weaken, it is still forecast to hit Baja California as a hurricane, and as a tropical storm as it moves north into California. Heavy rainfall is expected, with 3-6 inches in most areas but up to 10 inches in isolated areas of California and Nevada. Flash floods are possible in the area from San Diego to Las Vegas. If the storm reaches California, the National Weather Service says it will be the first since 1939.
