RESIDENTS piled into cars and fled downtown Santa Barbara, as surging winds drove one of the biggest fires in California’s history toward the city and the nearby wealthy enclave of Montecito.

The mandatory evacuations around Montecito and neighbouring Summerland came as winds that had eased on Friday roared back the next day at around 30mph, with gusts to about 60mph.

The 404-square-mile Thomas Fire was moving rapidly westward and crested Montecito Peak, just north of Montecito. Known for its star power, the enclave boasts the mansions of Oprah Winfrey, Ellen DeGeneres and many others.

Firefighters drove to the historic San Ysidro Ranch in yellow fire trucks as heavy smoke rose from the coastal hills.

A portion of Santa Barbara was under mandatory evacuation at the weekend, and at the city’s zoo, workers began putting some animals into crates and kennels, to ready them for possible evacuation.

There was better news down the coast, as emergency officials announced that the same fire that was burning about 25 miles south-east of Montecito was 40 per cent contained.

Since the fire began on December 4, about 95,000 people have been placed under mandatory evacuation. The evacuation zone near Santa Barbara on Saturday was 17 miles long and up to five miles wide and the new expansion encompassed about 3300 people.
