California’s getting soaked, but there’s still a wildfire across the Sierra Nevada with mandatory evacuations. My friend’s parents live just off Hwy 395 by Crowley Lake pictured below, right at the fire’s edge. 📸: CalFire

This atmospheric river delivered about a full November’s worth of rain. We were already running well above average for the water year, and today’s totals push Santa Cruz to roughly 257% of normal. A few really high totals at the coastal peaks like Ben Lomond Mountain too. #CAwx #CAwater

Storm clouds gather over Monterey Bay as last night’s stalled atmospheric river loomed offshore, ahead of today’s soaking rain.

Over 5 inches of rain on top of Ben Lomond Mountain in past 24 hours, no doubt getting an assist from the mountain orography, still raining. ☔️🌧️🌧️ #CAwx #AtmosphericRiver

Behold the atmospheric river rolling into California today.. a firehose of moisture wrapped into the rotation of an extratropical cyclone. 🌀🌧️🌧️🌧️

Given that nearly all of Santa Cruz county was covered in dense fog except a few peaks sticking out like islands in the sky, these might be some of the only photos from last night’s aurora storm around here. #auroraborealis

This is what the Eagle Rock camera looks like now. Caught the Aurora only moments before it was eaten by the fog.

Orographic lift is how terrain can cause rainfall in the Santa Cruz Mountains. When moist air rises up a mountain slope, it expands causing it to cool adiabatically. Cool air can’t hold as much moisture, so water vapor condenses, forming clouds, fog, and rain; the reverse of adiabatic compression.🧪
