Over 100 PG&E customers are without power and Columbia College was closed Thursday morning after a powerful overnight storm dumped approximately 1 inch of rain on Tuolumne and Calaveras counties.

PG&E spokesperson Brandi Merlo said outages in areas near Groveland, Sonora, San Andreas and Valley Springs appeared to be related to weather.

She said 99 customers were affected in Groveland, six customers were affected near Sonora, eight near San Andreas and 14 near Valley Springs.

According to a PG&E online outage map, the Groveland outage was located on Merrell Road and Harper Road, south of Highway 120. A preliminary determination on the post said the outage was caused by scheduled maintenance work.

The outage near Sonora was shown to be on the Columbia College campus. Tuolumne County Superintendent of Schools Cathy Parker said she was informed Columbia College was closed due to the overnight storms.

According to the Columbia College website, classes before 1 p.m. on Thursday were canceled due to a power outage. The website said online and offsite classes were still scheduled.

Parker said no other schools in Tuolumne County were closed Thursday.

The PG&E online map also showed an outage south of Highway 26 and Highway 12 junction, just adjacent to the Calaveras Unified School District Office.

Calaveras Unified School District Superintendent Mark Campbell said in an email all district schools were closed Thursday and Friday for the Calaveras County Fair.

Merlo estimated power would be restored before 3:30 p.m.

He said less than an inch of rain and possible thunderstorms was expected through the next 24 hours period. About three-quarters of an inch was expected through Thursday night, with a tenth of an inch on early Friday.
