Hurricane Blanca nears Mexico's Baja California peninsula

Hurricane Blanca was weakening even as it roared toward Mexico's Baja California Peninsula on Sunday, and authorities put thousands of troops on alert and businesses boarded over windows ahead of its arrival.

The unpredictable storm had strengthened rapidly to a Category 4 storm on Saturday before weakening to Category 2 by early Sunday, and forecasters said it should weaken to a Category 1 hurricane later in the day as it nears Mexico's coast.

It is expected to make landfall on Baja California's southwestern coastline Monday as a tropical storm. But the director of Mexico's National Water Commission, Roberto Ramirez, said he was concerned about Blanca's "erratic" behavior and warned residents along the coast to be prepared for intense rains.

In Baja California, 2,000 army troops and 1,321 marines have been put on alert, as well as emergency responders and power line technicians, said Civil Protection director Luis Felipe Puente.

He said there is currently a 70 percent hotel occupancy rate in Los Cabos and warned tourists to be attentive to any advisories issued by authorities

Some businesses and banks were seen hammering boards over their windows in preparation for Blanca's arrival. People began forming lineups at gas stations to stock up on fuel.

Blanca's maximum sustained winds had decreased Sunday morning to near 105 mph, according to the U.S. National Hurricane Center. The hurricane is centered about 200 miles south-southwest of Cabo San Lucas and is moving north-northwest near 12 mph.

A hurricane watch is in effect for an area from Cabo San Lucas to Santa Fe. A tropical storm warning is in effect from Loreto to Punta Abreojos, including Cabo San Lucas.

Puente said he saw no reason to suspend local elections scheduled to be held on Sunday.
