Monday School Closures:
Four school districts in San Diego County were closed Monday because of icy conditions and snow in mountain areas, according to the San Diego County Office of Education.
Julian Union Elementary School District, Julian Union High School District, Spencer Valley Schools District and Warner Unified School District will be closed.
"The safety of students and school staff is of the utmost importance to San Diego County school districts," the Office of Education wrote on its website.
Beach Advisory:
County beachgoers were advised to stay out of all coastal beaches and bays because of the danger of rain bringing water runoff, which can cause bacteria levels to rise significantly, officials said Sunday.
Rainwater coming from storm drains, creeks, rivers and lagoon outlets may cause illness, according to the Department of Environmental Health and Quality.
"Water contact such as swimming, surfing and diving should be avoided during rain for 72 hours following a rain event," the DEHQ said.

Two county roads were closed because of flooding, according to the San Diego County Department of Public Works. Country Club Drive, just south of Harmony Grove Road in Escondido, was barricaded and closed at 1:04 p.m. Sunday due to flooding and will remain closed until the rainstorm is over, the DPW said.
In Spring Valley, Quarry Road was closed at 1:27 p.m. from Elkelton Boulevard to state Route 125 because of flooding.
Most temperatures Sunday were in the 50s, with overnight lows in the 40s. The mountains were expected to be in the mid-40s, dropping into the mid- 30s overnight, and highs in the deserts were forecast in the mid-60s with lows in the mid-40s.
Snow levels fell through Sunday night, bottoming out around 3,500 feet Monday. Driving in these areas was expected to be treacherous due to low visibility in fog, snow, and blowing snow, the NWS said.
Tuesday and Wednesday were expected to be dry and cold followed by minor warming Thursday and Friday.
There was a chance for additional precipitation next weekend.
Rough seas, strong winds and heavy rain leading to reduced visibility may occur through much of Monday. A slight chance of thunderstorms was expected over the coastal waters Monday morning. Conditions were predicted to improve on Tuesday.
A longer-period swell of 7-10 feet at 12-14 second periods on Sunday led to some wave sets of up to 6-7 feet on some of the west-facing beaches on Monday and Tuesday, as well as enhanced risks for rip currents.
