Some 153,000 residents are under mandatory evacuation orders and another 166,000 have been warned they may have to flee, too.

The political repercussions have begun.

On Friday, Governor Gavin Newsom, a Democrat with rumored White House aspirations, ordered an investigation into why a key reservoir was out of service and some fire hydrants ran dry.

Los Angeles Fire Chief Kristin Crowley complained about the shortage.

“When a firefighter comes up to a hydrant, we expect there’s going to be water,” she said.

Chief Crowley has also attacked city leadership for cutting her department’s budget and eliminating mechanic positions, which she said had resulted in more than 100 fire apparatuses being out of service.
