What the National Weather Service wrote

There were three incidents reported in the Butte Fire area. Mud and debris covered Hawver Rd. at Jesus Maria Road in Mokelumne Hill along Calaveras River. Road was closed until the debris was cleared. That intersection has a small makeshift bridge over the creek that is made of concrete over about 8 six inch pipes that lie in the river bed. The pipes clogged and the creek overflowed the small bridge. There were also a few small rock slides and mud slides along some of the highways. Highway 26 and Woodhouse Mine Road in West Point had a mud slide, but this did not close the road. The road is open however. There was also a small rock slide on Mountain Ranch Road at Rocky Road.

The wider storm

A wet storm brought heavy rain and heavy high mountain snow, along with strong winds. The heavy rain caused some debris and mud flows in recently burned areas.

Began near Mokelumne Hill (38.2800, -120.6700).
