The extraordinary plume of subtropical moisture that moved ashore Monday was continuing to drench San Diego County Tuesday morning in what could turn out to be nearly a week’s worth of messy weather.
A flood watch will be in effect for all of San Diego County from Thursday evening through Friday evening as a slow-moving storm travels through Southern California.
The National Weather Service said rainfall over the next two days is expected to total .75 to 1.5 inches for the coast and valleys, 1 to 2 inches for the mountains, and up to an inch in the deserts.
An atmospheric river will continue to impact the West Coast over the next 24 hours.
A record amount of moisture is hitting the Pacific Northwest as the powerful system continues to bring heavy rainfall to the region.
A Pacific storm that was expected to drench San Diego County late Friday and early Saturday is turning away from the region and won’t deliver rain that’s needed to help reduce the risk of wildfires ahead of Santa Ana winds next week, the National Weather Service said.
Forecasters originally thought the system would drop about 0.70 inches of rain west of Interstate 15 and as much as an inch in the valleys, foothills and mountains to the east.
Tropical Storm Hilary drenched Southern California from the coast to the desert resort city of Palm Springs and inland mountains, forcing rescuers to pull several people from swollen rivers.
By early Monday, remnants of the storm that first brought soaking rains to Mexico’s arid Baja California peninsula and the border city of Tijuana, threatened Nevada and as far north as Oregon and Idaho with flooding.
Southern Californians were battling flooded roads, mudslides and downed trees.
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
A close examination of nearly 2,000 of the world’s largest lakes found they are losing about 5.7 trillion gallons (21.5 trillion liters) a year. That means from 1992 to 2020, the world lost the equivalent of 17 Lake Meads, America’s largest reservoir, in Nevada. It’s also roughly equal to how much water the United States used in an entire year in 2015.
Here’s how much rain fell across San Diego County during the five day period ending at 1 a.m on Sunday, according to the National Weather Service.
Although the number wasn’t huge for San Diego, the city has now received 9.57 inches of rain since the rainy season began on October 1. That’s only 0.20 inches below what the city averages from October 1 to September 30.
After the driest three years in the state’s modern history, California suddenly has a different problem on its hands: too much water.
An ongoing series of storms drenching the state has forced officials to take measures unfathomable just a month ago, like releasing excess water from reservoirs and pumping surging river flows into storage.
Good news has surfaced in Los Angeles County’s ongoing battle with water scarcity.
The Los Angeles County Public Works Department announced Monday that more than 33 billion gallons of stormwater have been captured in the early months of the California winter storm season.
It will be used as drinking water and is enough to supply 816,000 people with enough water for an entire year, according to Los Angeles County Public Works Director Mark Pestrella.
