From John Lindsay:   “1,007 millibar low-pressure system off the Northern California coastline will move southward. This system will produce moderate to fresh (13 to 24 mph) southerly winds, increasing clouds and periods of rain starting Tuesday afternoon, which will continue  through Thursday morning as this storm moves over San Luis Obispo  and Santa Barbara counties.  A few rain showers will linger into Thursday afternoon.   This system will also bring a chance of isolated thunderstorms capable of heavy rainfall, gusty winds, hail, and lightning. At this time, between 0.75 and 1.75 inches of precipitation is expected from this system. This tempest will bring the coolest temperatures on Tuesday and Wednesday, with highs only reaching the mid-50s as a cold and unstable air mass moves into Central California. Snow elevations are expected to drop to 2,500 and 3,000 feet and may fall even farther at times, especially overnight Tuesday and Wednesday.”

Per Santa Cruz County: “Rainfall from this system is expected to approach but not exceed thresholds for debris flow evacuations in the #CZULightningComplex burn scar. Prepare a go bag in case conditions change. Protect yourself, protect your family. Text SCR911 to 99411 to sign up for emergency alerts.“

From NOAA: “The Santa Lucia and S Gabilan Range could see 5-10″ [of snow];
