San Diego weather

East County News Service

Last week’s storms brought 6-10 inches of snow to our mountains with up to 1.5 inches in urban portions of our county.  Now, multiple new storms are moving into the area, with rain now falling across the region and multiple atmospheric rivers soon to drench  our region, with the heaviest rains Thursday, the National Weather Service predicts.   A flood watch has been issued now through Thursday afternoon for San Diego’s inland and coastal areas, including cities such as La Mesa, Santee, Poway, and Escondido as well as San Diego.  Excessive runoff may result in flooding of rivers,  streams, and other low-lying and flood-prone locations.

Wednesday night through Thursday afternoon could bring rainfall rates of .5 to 0.75 inches per hour, with up to an inch per hour possible in lower mountain areas, along with thunderstorms.  Two to three inches of snow are forecast at higher elevations locally. A winter storm warning will remain in effect from Wednesday afternoon through Friday morning.

Travel could be very difficult to impossible. The   hazardous conditions could impact the Tuesday morning and evening   commutes. Very strong winds could cause extensive tree damage.   Roads, and especially bridges and overpasses, will likely become   slick and hazardous. Visibilities may drop below 1/4 mile due to   falling and blowing snow.

Yet another storm is possible Sunday and Monday, with continued colder than normal temperatures.

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.

Inland valleys and lowlands may also see gusts over 40mph.  A second round of Santa Ana winds is expected Thursday.

There is a chance of patchy fog that may reduce visibility in the early morning, resulting in hazardous conditions for travel.

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

“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.

Over 30,000 residences have been evacuated in cities including Santa Monita, Topanga, Malibu, and Pacific Palisades.
