With ferocious winds driving multiple wildfires through bone-dry vegetation and nearly 200,000 people ordered to leave their homes, California's governor declared a statewide emergency Sunday. Meanwhile, millions of residents remained without power after the state's largest utility cut electricity as a precaution to prevent more areas from igniting.

Governor Gavin Newsom said in a statement that officials were deploying "every resource available" to respond to the wildfires, including a large blaze in northern California's wine country powered by gusts that reached more than 102 mph (164 kph). California Fire officials said Sunday that the fire had grown to burn over 85 square miles, and officials reported containment had dropped to 5 percent. At least 94 structures have been destroyed.

In the San Francisco Bay Area, two grass fires briefly halted traffic on an Interstate bridge. The flames came dangerously close to homes in Vallejo. Another grass fire closed a stretch of interstate that cut through the state capital as smoke obstructed drivers.

In the south, a wildfire in the Santa Clarita area near Los Angeles destroyed 18 structures. As of Sunday night, the Tick Fire was 70 percent contained.

The biggest evacuation was in Northern California's Sonoma County where 180,000 people were told to pack up and leave, many in the middle of the night.

To prevent its power lines from sparking in the high winds and setting off more blazes, Pacific Gas & Electric said Sunday that preventative shut-offs impacted 965,000 customers and another 100,000 lost electricity because of strong gusts, bringing the number of residents impacted by blackouts to nearly 2.7 million people.

PG&E officials say they are expecting strong winds to whip up again Tuesday and that they have notified 500,000 customers – or more than 1 million people – that they are likely to have their power turned off for the third time in a week. Some of those people might not have their power restored from the current outage before the next major shutdown, which would leave them without electricity for five days or longer, said Mark Quinlan, PG&E's emergency preparedness and response director.

The fear that the winds could blow embers and spread fire across a major highway prompted authorities to expand evacuation orders that covered parts of Santa Rosa, a city of 175,000 that was devastated by a wildfire two years ago.
