Hurricane Jimena Bearing Down on Baja, California

MIAMI, Florida (CNN) -- With winds of 135 mph, Hurricane Jimena was approaching Mexico's Baja California peninsula on Sunday as a Category 4 storm, forecasters said. "There's a good chance this system could be a Category 5 in the next 24 hours," said Dave Roberts, a hurricane specialist with the National Hurricane Center.
As of midday Sunday, Jimena was located about 285 miles (458 km) south of Cabo Correintes, Mexico, or about 500 miles (804 km) south-southeast of the southern tip of Baja California, Roberts said. The storm is expected to continue in a north-northwest motion and approach the southwestern tip of Baja California sometime early Tuesday, he said.
Jimena is the 10th named storm of the Pacific season.
"It started out kind of slow for the Pacific," said Robbie Berg, another specialist at the hurricane center. "But actually August, now we've had seven named storms form, and that's pretty busy for August. We haven't seen that -- I think it's been a couple decades since we've seen that many storms in August."
There's no reason for people in that area to panic, but they should keep an eye on Jimena, Berg said.
"There's no watches or warnings in effect, but we would like residents and tourists in the area to monitor the progress of the storm," Berg said. "We do expect it to maintain its major hurricane strength as it heads up into that area."
Tropical Storm Kevin has also emerged in the middle of the Pacific Ocean. However, Berg says it is weak -- with winds at 50 mph -- and is not expected to pose a serious threat.
