Gov. Gavin Newsom has ordered an independent investigation into how the loss of water left dry fire hydrants and hindered firefighting efforts in Los Angeles.

Water experts dismissed Trump’s claims that California water policy is to blame for dry hydrants. But Los Angeles is also unprepared for the age of urban wildfires.

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

Though wildfires have always happened, warming global temperatures are making them more frequent and severe. For instance, scientists calculated last year that our overheating planet has contributed to a 172% increase in areas burned by wildfires in California since the 1970s.

Reports of fire hydrants running dry as crews battled the Palisades Fire has raised questions among residents and fire officials in San Diego County whether it is something that could happen here when the region gets next major wildfire — and what can be done about it.

Fire hydrants ran dry in Los Angeles just when they were needed most to fight one of the most destructive fires in the city's history.

We had tremendous demand on our systems in the Palisades,” Quiñones said. “We pushed the system to the extreme. Four times the normal demand was seen for 15 hours straight.”
