Powerful Santa Ana winds sweep parts of Southern California

December 17, 2019 GMT

LOS ANGELES (AP) — Powerful Santa Ana winds swept mountains and valleys of Southern California on Tuesday, toppling several big rigs and trees.

The National Weather Service issued a high wind warning and said it would be in effect for most of the day.

A predawn gust hit 88 mph (142 kph) in Fremont Canyon in the Santa Ana Mountains of Orange County, the weather service said. Another gust hit 74 mph on Boney Mountain in the Santa Monica range west of Los Angeles.

Trucks ended up on their sides on Interstates 15 and 8 as well as on State Route 118. Dozens of other drivers pulled over and parked alongside highways as winds buffeted their rigs.

Produced by high pressure over the Great Basin, the winds were expected to gradually diminish in the afternoon and evening.
