Half the state remains locked in drought with impending fire risk and a dwindling rainy season while NorCal is set to see a verdant spring.

SOUTHERN CALIFORNIA — While Northern California is basking in a verdant spring following an exceptionally wet winter, the Southland is in the midst of a severe drought following a bone-dry rainy season.
In January, weather experts told Patch that Southern California had slipped back into a drought after experiencing the driest start to its normal rainy season on record. Despite recent storms, most of the region has since slipped into extreme drought conditions, priming the Southland as a tinderbox as the weather heats up.
Southern California had a few solid storms, namely atmospheric rivers, in February and March, but the region is still in a rainfall deficit, says Jayme Laber, a hydrologist with the National Oceanic and Atmospheric Administration. What's more, the storms didn’t appear to make a dent in the moderate to severe — and in some cases, “exceptional” — drought conditions plaguing parts of the region.
According to the U.S. Drought Monitor, Santa Barbara, Ventura and Los Angeles counties are all in severe drought. Parts of Riverside, San Diego, Imperial and San Bernardino counties are under extreme drought. Exceptional drought conditions — the most extreme level is beginning to spread in the most inland regions of the Southland, according to weather experts.
“Because it was so dry in December and January, we dug ourselves in a pretty big hole, deficit-wise for rainfall,” Laber said. “So even though we had the rainfall in February and March, we're still behind… We're lower than normal.”

Downtown Los Angeles is currently at about 60% of its average rainfall for this time of year, he said. At the start of the year, Laber noted, that percentage was much lower — low enough to contribute to extremely dry conditions that weather officials warned of just before the devastating Los Angeles fires ignited in January.
The rainy season itself played out unusually in Southern California specifically, Laber said.“February and March were pretty typical… but December and January being as dry as they were… we got ourselves into a pretty big precipitation deficit,” he said.
The good news is Laber says the rainstorms over the past two months did help to quell a lingering fire season, fueled by bone-dry landscapes.
“We did have enough rain in February and March that it has reduced the fire concern for now,” he said.

“The situation was looking worse at that time, but February and March have helped,” Laber said. “But again… we're still 60% of normal… which still has us talking about being in drier than normal, like drought conditions."
Meanwhile, NOAA reported on March 20 that Northern California enjoyed a "wetter than average precipitation pattern."
Despite a lackluster rainy season and half a state steeped in drought, Laber said that water supplies are still in robust supply thanks to very wet winters in 2022 and 2023.
“Our reservoirs and our groundwater, we're still in pretty good shape… One year where we're below normal isn't going to have a super amount of impact,” he said. “The reservoirs and the water supply system in California is made to be able to withstand several years in a row that are dry.”
He emphasized that while Southern California is struggling with dryness, “Northern California and Central California have done pretty good… normal to above normal.”
Still, Laber said it’s never a bad time to conserve.
“There's a lot of desert areas around here, and we could almost consider ourselves like a coastal desert… It's always a good practice to maintain,” he said. “We should never lose sight that when… times are good, that the next year might be really dry.”
As spring begins, Laber said that the state is at the tail end of its rainy season.
“Those three wettest months are generally January, February, March… We still might get a little bit of rain in April, May. But… it's not those big storms,” he said. “The Drought Monitor maps are going to become static through the… summer and into fall and into next winter.”
"This winter, we were… under the influence of La Niña,” he said, adding that “sea surface temperatures… are starting to slightly warm up… trending towards more of a neutral condition.”
But arid times are just waiting around the corner again.
But he warned that recent warm temperatures could quickly shift the risk again.
"Where I live, my house was 92 degrees yesterday, so we're back in some warmer times," he said. "That can dry that vegetation out fairly quickly, and so it wouldn't it won't take long...to get back into a situation where we are going to be back into a high fire danger."
Despite the Southland's stable water supply, Laber urged that it's never a good idea for residents to drop their guard. That's because SoCal is something of a "coastal desert," he explained.
"We should never lose sight when times are good," he said. "The next year might be really dry again and we don't want to be wasting water."
