Mountains and deserts forecast to get 5-7 inches of rain, with winds up to 60 mph

August 17, 2023 (San Diego’s East County) – Hurricane Hilary is barreling toward San DIego County, slated to hit this weekend.

“The storm is going inland, so the strongest winds will be in the mountains,” meteorologist Miguel Miller with the National Weather Service in San Diego told  East County Magazine. “The rainfall, flood potential and winds are actually going to be stronger the more east you go. This will be a really wet and windy storm.”

Currently a category 2 hurricane, Hilary could be upgraded to a category 4 by the time it hits Baja, Mexico, though it will likely be downgraded to a tropical storm once it reaches San Diego County. However, the impacts will still pack a wallop, with thunderstorms, very heavy rains and flooding likely --with the worst in inland areas.

Desert areas are forecast to be soaked with 5-7 inches of rain, with 5-7 inches in the mountains, 2.5 inches in Alpine, and 1.75 inches in El Cajon from Saturday through Monday. The worst of the storm is expected to peak on Sunday.

Wind gusts of 40 to 60 miles per hour are expected in the mountains, with 30 to 50 mph winds on the desert floor. West of the mountains, 30 to 40 mph winds are forecast. High surf will occur along the coast.

This isn’t the first time a hurricane has hit our region.

Back in September 1976,  Hurricane Kathleen had a similar trajectory. Designate a tropical cyclone by the time it reached our region, it as ECM previously reported on an anniversary of that storm, it caused massive flooding and destruction.

July 12, 2023 (San Diego’s East County) – The National Weather Service predicts a long-duration heat wave will impact San Diego’s inland areas through next week, potentially breaking records. Triple digit temperatures will bring extreme heat risk in desert areas, with the highest temperatures Saturday through Monday, along with elevated fire weather conditions each afternoon and evening.

High temperatures are expected to reach 115-121 degrees in low desert areas such as Anza-Borrego and 105-112 degrees  in high desert areas. Mountains should reach 95-105,with San Diego’s valleys reaching 92-103 degrees. Temperatures are expected to stay warm even overnight, with lows temperatures of 80-90 degrees in low desert areas and lows in the 70s in the mountains and high desert communities.

June 1,2023 (San Diego) -- With summer just around the corner, the County of San Diego opened its annual Cool Zones program Thursday to give people free, safe, air-conditioned sanctuaries to escape extreme heat.

The County created the Cool Zone Program two decades ago to give older adults, people with disabilities and those with health concerns that could be complicated by the effects of extreme heat.

The program will run from June 1 through Oct. 31; sites include the County’s 33 branch libraries, community centers and other locations across the county.

A complete list of Cool Zone sites, their hours and locations is located online. The site includes a map feature where people can type in their address to find locations near them. People can also call 2-1-1 to find a location, or, if they cannot get to a Cool Zone, ask for help with free transportation.

March 27, 2023 (Potrero) – A 300-year-old old oak tree toppled onto the porch of the former Potrero Café, next door to the historic Potrero Store, which was built in 1883 and first operated by Joseph and Damond Thing. The store remains open.

“The restaurant’s been closed for six years,” Michael Streenan, owner of the property, told East County Magazine. The tree damaged two exterior porches and an asphalt parking lot, but fortunately the buildings on the property are intact, he said.

“No one was injured when the tree fell. “Nobody even heard it come down. We just came out and saw it,” says Ryan Streenan, Michael’s son.  Neither of the Streenans knows how old the café building is, though Ryan said it may have been a house for former owners of the store.

The most likely cause of the massive tree’s collapse is the recent heavy rainfalls that have left the ground saturated.  “I guarantee you we’ve had 10 inches here,” says Jan Hedlun, a member of the Potrero community planning group. “I’ve been stranded three times on my own driveway because the water’s been 15 inches deep.  I had one oak tree branch break and fall; another tree had a branch come down.”

March 3, 2023 (San Diego) – The National Weather Service has released precipitation totals for the three days ending March 2.  Residents have been left snowed in at some San Bernadino mountain towns, with Bear Mountain receiving nearly 5 feet of snow and snow resorts such as Big Bear and Snow Valley around 40 inches.  Here in San Diego County, Palomar Mountain got another 20 inches of snow and Mount Laguna another 10 inches, atop multiple feet of snow already on the ground, while Julian got 4 more inches.

Across the country, storms the past three days also brought substantial rain. Lake Henshaw had 3.85 inches and Santa Ysabel had 2.21 inches. El Cajon, La Mesa, and Santee had between 1 and 2 inches, while Borrego’s Palm Canyon in the desert got .84 of an inch.

The storm also brought hail to much of the region, from coastal areas such as Encinitas, El Cajon and La Mesa.

Extreme weather also caused some power outages, with some Borrego Springs residents left in the dark for nearly a full day.

February 27, 2023 (Santa Ysabel)-- The weekend storm brough snow to unusually low levels in San Diego County's mountains. With  popular destinations such as Julian, Cuyamaca and Mount Laguna blocked except to residents and chains required in the morning, followed by traffic jams when some highways later opened, ECM's editor and photographer headed to Santa Ysabel instead.

Visitors pulled off alongside the highway were enjoying building a snowman and tossing snowballs, with dogs frolicking in the snow. Several motorists paused to pose for pictures with horses standing just behind a barbed wire fence.

Blue skies,puffy clouds and sunbeams warming the terrain completed this idyllic scene.

February 23, 2023 (San Diego’s East County) – Treacherous. Severe. Really dangerous conditions. Those are terms used by National Weather Service meteorologist Alex Tardy in a webinar today to describe  a slow-moving atmospheric river, coupled with high winds and frigid temperatures from an arctic jet stream, swooping into San Diego County Friday and Saturday.

The storm could dump a potentially unprecedented three to five feet of snow at elevations above 4,000 feet in some parts of Southern California, with another foot and a half forecast on Mt. Laguna atop considerable snow that's already fallen.  Also forecast are debris flows in areas not normally subject to them as snow melts. Blowing and drifting snow will impact major southern California highways, including highway 78 and the eastern portions of Interstate-8 in San Diego County.
