Hurricane Blanca intensified off the Pacific Coast of Mexico on Saturday and has been upgraded to a Category 4 hurricane packing 130 mph winds, forecasters said.
A new Tropical Storm Warning was issued for the coast from La Paz to Santa Fe, including Cabo San Lucas, and a Hurricane Watch is in effect from Cabo San Lucas to Santa Fe, the National Hurricane Center said in an overnight update.
An earlier update said Blanca had become a "major hurricane" again.
The severe storm is expected to dump 6 to 10 inches of rain on much of Baja California Sur and the southern portion of Baja California when it hits late Sunday or early Monday, the NHC said.
Hurricane Blanca is expected to maintain its strength before a weakening trend begins late Saturday or early Sunday, The Weather Channel said.
The resort zone of Cabo San Lucas is still recovering from Category 3 Hurricane Odile which ravaged the area in September and was the strongest storm there in 25 years.
