CABO SAN LUCAS, MEXICO -- v>

Hurricane Hilary roared toward Mexico's Baja California peninsula late Saturday as a downgraded but still dangerous Category 2 hurricane likely to bring "catastrophic" flooding to the region and cross into the southwestern U.S. as a tropical storm.

Meteorologists warned that despite weakening, the storm remained treacherous.

One person drowned Saturday in the Mexican town of Santa Rosalia, on the peninsula's eastern coast, when a vehicle was swept away in an overflowing stream. Rescue workers managed to save four other people, said Edith Aguilar Villavicencio, the mayor of Mulege township.
