Southern California is bracing for a significant rainstorm expected to begin Wednesday, marking what meteorologists predict could be a very wet March. After a slow start to the rainy season, this storm is anticipated to bring much-needed moisture to the region, which has been facing one of its driest starts in recorded history.
Rain is expected to start around noon in Los Angeles County, moving down from the Central Coast. The heaviest rainfall is predicted to occur late Wednesday and continue through early Friday. Robbie Munroe, a meteorologist with the National Weather Service in Oxnard, indicates that more rain will likely follow next week, further aiding the parched landscape.
As of now, downtown Los Angeles has received only 5.58 inches of rain since the water year began on October 1, falling short of the average of 11.08 inches for this time of year. The annual average stands at 14.25 inches. Munroe noted that while February provided some relief, it still left the area behind in terms of rainfall.
This week’s storm is expected to deliver between one-tenth to one inch of rain along the coast and between one to two inches in the foothills and mountains. Higher elevations above 4,500 feet could see two to five inches of snow. The weather service has also issued warnings for strong winds, with gusts reaching between 30 and 50 mph on Thursday.
Thunderstorms may develop, particularly from Wednesday night into Thursday, bringing heavy downpours along with gusty winds and possibly small hail. There is a 10% to 20% chance of weak tornadoes during this period. While the rain is generally welcome, experts warn that rapid rainfall could lead to debris flows, especially in areas affected by recent wildfires.
Angela George-Moody, chief deputy director of L.A. County’s Department of Public Works, emphasized that preparations are in place. Crews have cleared flood control facilities to handle runoff, and residents are urged to take precautions by clearing drainage paths and using sandbags to protect their homes.
The upcoming storms could help bolster California’s snowpack, which is crucial for the state’s water supply. As of Tuesday, the snowpack was at 83% of average for this time of year. A wet March could also delay the onset of the high fire season, providing some relief to the region.
After this storm, there may be a brief dry spell before another system arrives Sunday night, bringing more light to moderate rain into early next week. Meteorologists are keeping a close eye on these developments, as the exact amounts and impacts of the upcoming storms remain uncertain.
