Caltrans crews put sand on highways to stop black ice. The extra coat of dirt prevents skidding and is especially important on bridges.

Workers are on standby in case snow dumps on the foothills overnight. If wintery weather makes it down to the Valley floor they will hit busy freeways.
"If it does happen to snow they are going to saturate 99 first because a lot of people on the freeway are not prepared on how to drive in the snow whereas people in the foothills are prepared for snow conditions,"

"We have a lot of calls on heaters - mainly heaters breaking down," Alex Nguyen with Vern's plumbing and heating said.

Their utility crews are on standby for another potential problem.
"Our biggest concern right now is preparing for outages that come from the storm," Boyles said.
