Cooler, Wetter Weather Expected to Displace Warming Trend By Mid-Week
San Diego County is experiencing mild and dry weather, but rain is likely on the way later in the week, forecasters said.
San Diego County is experiencing mild and dry weather, but rain is likely on the way later in the week, forecasters said.
Monday is expected to be much drier than the weekend but there is a chance for showers overnight, the National Weather Service said. The next storm system is expected to approach next weekend.
The violent second wave of a massive Pacific storm lashed San Diego County on Tuesday, bringing enough rain to flood the San Diego River and thunderstorms that led to a brief — and rare — tornado warning.
The pump is primed for another stretch of very stormy weather next week and into early February. What forecasters have yet to fully determine is where the next fire hose of moisture will be aimed: at San Diego again, at points to the north or even at the entire state of California.
Increased rainfall, with a growing chance for heavy precipitation over Christmas, is expected across much of California, beginning next week and lasting through the rest of December.
El Niño has arrived, and the climate pattern is likely to bring above-average moisture to the southern U.S. this winter.
El Niño is one of two climate patterns that greatly impact Earth’s weather. La Niña recently culminated in the spring, ending a multiyear period in which the pattern influenced the weather. El Niño started in June, and the National Oceanic and Atmospheric Administration’s (NOAA) most recent update has identified El Niño as having high odds of being historically strong.
That means parts of California could see another wet winter, a welcome weather pattern as many of the state’s lakes and reservoirs continue to recover from a years-long drought. But an El Niño year doesn’t guarantee excess moisture in Southern California.
Record rain totals were reported in Alpine in San Diego County Monday, according to the National Weather Service.
There was 0.13 inches of rain reported in Alpine on Sunday, breaking the record for the day of 0.03 inches recorded in 1963.
The highest rain total recorded over the past two days in San Diego County was 0.70 inches in Lower Oat Flats. There was 0.47 inches reported in Palomar and 0.40 inches in La Jolla
El Niño conditions — the warming of ocean waters off South America that can alter weather across the globe, including California’s summer temperatures and the amount of rain it might receive next winter — are emerging in the Pacific Ocean for the first time in 4 years.
While El Niños do not automatically guarantee wet weather for California, historically, the stronger they are, the more likely it is that the state will have a rainy winter season. And after the dramatic series of storms this past winter that ended the drought and filled nearly empty reservoirs, another one back-to-back could increase flood risks.
The deserts of San Diego County are alit with wildflowers.
Record rains have fallen over most of San Diego County, and as of recently, the same is true of the desert.
It’s been an unusual bloom in the Anza-Borrego Desert State Park. Why? Uncommon summer monsoons in September of last year triggered the first fall blooms, pulling blankets of violet sand verbena up over the desert dunes, according to Jim Dice, Reserve Manager at the University of California, Irvine’s Steele/Burnand Anza-Borrego Desert Research Center in Borrego Springs.
Flowers are blooming in the desert. Flooding and sewage spills have largely receded. Dams continue to collect runoff. But the drought is still far from over.
San Diego recently weathered a monthlong series of storms that also blanketed much of the West with badly needed snow. Still, the possibility of state-mandated water restrictions looms over the region this year, especially if dry conditions return to the Sierra Nevada.
Residents and local officials in San Diego are now taking stock of the situation as the deluges appear to be giving way to sunnier skies. While urban areas are still riddled with potholes and beach closures, rains have revived parched natural landscapes.
