Thousands of Southern California residents remained without power Thursday as strong winds knocked down power lines and blew blinding dust across desert roadways.
More than 19,000 customers from the Los Angeles Department of Water and Power still were without electricity.
The outrages stretched from the San Fernando Valley to south Los Angeles, said agency spokeswoman Carol Tucker.
The winds should subside by late Thursday after making it a blustery holidays in Southern California.
High winds on Christmas Day blew down power lines and transformers, and utility crews were placed on standby in anticipation for more strong gusts.
The National Weather Service issued high wind warnings for the Antelope Valley and mountain areas of Los Angeles and Ventura counties.
Unlike last month's hot, dry Santa Ana winds, the latest gusts were coming from the north and were cold and moist, weather service meteorologist Jamie Meier said.
Meanwhile, a broken wind sensor in Thousand Oaks misreported gusts were blowing more than 100 mph on Tuesday.
Weather officials didn't notice the error until after the report was on the Internet and in the local newspaper. Winds were actually blowing more in the 50 mph range.
"It was a reasonable speed for the event, just not at that location," Meier said, referring to the erroneous report.
It's not uncommon for wind sensors to break.
When they do, sometimes they transmit wind speeds that are improbably high, sometimes they get stuck at a particular speed, and sometimes they don't transmit at all.
