Another few inches of rain fell in San Luis Obispo County on Wednesday as the multi-day storm continued to move through the region.

Rocky Butte, a mountain northeast of Cambria, again saw the most rain, measuring 3.51 inches in the past 24 hours as of 9 a.m. Thursday, according to the National Weather Service.

Most other areas of the county saw between an inch and 3 inches of rain during the same period, the Weather Service’s data show.

Periods of heavy rainfall caused minor flooding in some areas of the county and led to roadway closures and mudslides.
