Funnel cloud over Lake Tahoe 🙀#tahoe

A waterspout, which is a tornado that touches down on water, hit Lake Tahoe Wednesday amid some severe thunderstorm conditions, prompting a tornado warning for the whole lake. Multiple pictures of it like the one above appeared on social media, and the National Weather Service confirmed that it did touch down on the lake, but not on land.

This all happened around 4 p.m. Wednesday, and the tornado warning expired at 4:45, as CBS 5 reports.

The waterspout was just one of many weird, unstable weather conditions this week in Northern California, which included downpours of hail Monday and Wednesday, and a dramatic, hours-long thunderstorm over the Bay Area Monday night.
