Winter Storm Warning in effect – Welcome to San Bernardino County

Moderate to heavy rain and mountain snow are expected through Friday.

Heavy rain and measurable snowfall are expected in San Bernardino County today, March 6, and perhaps tomorrow, with more on the way next week. The National Weather Service has issued a Winter Storm Warning and stated today’s storm poses a threat to those living downstream of the areas burned by September’s Line and Bridge wildfires.

Residents are urged to prepare and sign up for emergency phone and text alerts. Motorists are advised to use caution and, as always, no snow play in the roadways!

Preparedness is a shared responsibility, and the strongest link in the disaster-ready chain are county residents and the measures they take to prepare. San Bernardino County created Preparedness Starts Here, a campaign and website giving residents the tips and tools they need to prepare for and survive floods and mudslides, wildfires, earthquakes, extreme cold, extreme heat, power outages and more.

San Bernardino County emergency responders are working around the clock, monitoring the rainfall and the effect it is having on our roads and scorched watersheds, and are poised to take action if the need arises.

The San Bernardino County Fire Protection District is fully staffed with all equipment operational. This includes snow cats, which are strategically located throughout County Fire’s mountain division to ensure response capability in all weather conditions. All fire stations maintain a cache of sandbags with sand being available at most stations on a first-come, first-served basis.

The San Bernardino County Sheriff’s Department’s Aviation Division has swift water and air rescue resources available and on standby.

County Public Works Operations crews began 24-hour coverage at 6 a.m. on Wednesday, March 5 and will remain activated until the end of the storm. The operations team covers 14 road yards and six Flood Control zones spread out across the county. All road culverts, drains, debris basins and channels have been cleaned out and are expected to function with no issues. K-rail has been installed at strategic locations to protect private properties and businesses. Crews installed 980 feet of K-rail and crash sled in Mt. Baldy, 300 feet in Wrightwood, and 1,340 feet along Flood Control District facilities in the Highland area.

Public Works has more than 100 pieces of equipment pre-staged in all yards, including loaders, motor graders, plow trucks, skid steers, blowers, dozers and backhoes. Road Operations crews will start snow plowing once snow has stopped falling and will focus on plowing primary roads first to keep access for emergency services and then move to secondary roads. All county-maintained roads will be plowed within 36 hours from when the storm ends.

Crews began evacuating people experiencing homelessness from county flood control facilities Wednesday morning and storm patrols will remain activated for the duration of the storm.
