As wildfires roar into residential neighborhoods, firefighters in California and elsewhere are finding that water systems can’t keep up with the demand.

Firefighters are making progress slowing the major fires in the Los Angeles area that have killed five people, ravaged communities from the Pacific Coast to Pasadena and caused thousands of people to flee their homes.

Los Angeles County fires have raged across communities and destroyed more than 27,000 acres and 2,000 homes, businesses and other structures. The fires have displaced thousands of people as they escape the blazes for safety.
