January 19, 2025 (San Diego) – January’s freakish weather continues with both fire danger and frost forecast for this week.  The weather hazards line up for a potentially “worse case” scenario, the National Weather Service predicts.

A red flag warning has been issued for San Diego County’s inland mountains and valleys Monday and Tuesday due to low humidity and strong winds forecast.

Cold mornings will also bring frost in sheltered inland valleys west of the mountains.

Widespread wind gusts over 35 miles per hour are expected, with a high potential for gusts up to 60 miles per hour in the mountain areas Monday and Tuesday.

January 8, 2025 (San Diego's East County) -- The National Weather Service has issued a red flag warning for San Diego County mountains and valleys today and tomorrow due to high winds and extreme fire danger. The strong winds that have fueled two large wildfires decimating Los Angeles County are forecast to move into San Diego County next.

This is the driest winter period measured from October 1 through January 8 since 1850, according to the National Weather Service, increasing fire danger.

Due to high winds and potential power outages, schools in six local districts will be closed today. The San Diego County Office of Education announced the closures for:

• Julian Union Elementary School District
• Julian Union High School District
• Mountain Empire Unified School District
• Ramona Unified School District
• Spencer Valley School District
• Warner Unified School District

“The safety of students and school staff is of the utmost importance to San Diego County school districts,” officials said in a news release.

In Los Angeles County, devastating fires have collectively destroyed over 1,000 homes and two people have died, the Los Angeles Times reports.
