Last Updated Oct 12, 2017 2:45 PM EDT

Friends and family are rushing to find out whether loved ones are at hospitals or shelters as deadly fires sweep across wide swaths of California and authorities announced new evacuation orders and new figures on homes and businesses that were loss.

Officials report that thousands of firefighters are battling nearly two dozen blazes in Northern California's wine country -- with additional help on the way.

As firefighters struggle to gain control of any of the fires, Gov. Jerry Brown held a press conference Wednesday and released the latest figures on the fight and response to the fires.

"We have had big fires in the past. This is one of the biggest, most serious, and it's not over," Brown said. 

CBS News has compiled some of the key numbers about the fires. All statistics are courtesy of Brown's office, unless otherwise noted.

California National Guard response:

  • 700 soldiers and airmen supporting firefighting and evacuation efforts Wednesday
  • Mobilized 1,800 more soldiers and airmen, including 49th Military Brigade

Meanwhile, cooler weather and moist ocean air has helped the fire fight in Southern California, CBS Los Angeles reports.

The Associated Press reports that the blaze in the Anaheim Hills in Orange County was nearly halfway surrounded and full containment was expected by Saturday, but another round of gusty winds and low humidity levels could arrive late Thursday.
