A late-winter storm doused the San Diego area with rain and mountain snow for second day Thursday, but a dry spell lies ahead.
Though the showers generated by the unsettled atmospheric system out of the Gulf of Alaska were more scattered and short-lived than Wednesday’s storms, they added to some significant moisture amounts across the county, according to the National Weather Service.
A cold, late-winter Pacific storm brought rain and snow to California on Tuesday. Winter storm warnings were posted or scheduled to take effect during the day in mountains from the Oregon border south to the U.S-Mexico border. Mountain travel was discouraged due to the potential for major delays, chain controls and near-whiteout conditions, the National Weather Service said. The San Francisco Bay Area weather office warned of possible hail, thunderstorms and downpours that could make driving risky.
As the planet warms, scientists expect that mountain snowpack should melt progressively earlier in the year. However, observations in the U.S. show that as temperatures have risen, snowpack melt is relatively unaffected in some regions while others can experience snowpack melt a month earlier in the year.
The winter storms that dumped heavy snow and rain across California early in 2021 are likely not enough to negate what will be a critically dry year, state water officials believe.
California’s Department of Water Resources on Tuesday recorded a snow depth of 56 inches and water content of 21 inches at Phillips Station in the Sierra Nevada. The water content of the overall snowpack was 61% of the average for March 2 and 54% of the average for April 1, when it is historically at its maximum.
Anyone who has hosted a good dinner party knows that the guest list, table setting and topic of conversation play a big role in determining whether the night is a hit or the guests leave angry and unsatisfied.
That concept is about to get a true test on the Colorado River, where chairs are being pulled up to a negotiating table to start a new round of talks that could define how the river system adapts to a changing climate for the next generation.
San Francisco’s rain total for February — typically the heart of the rainy season along with December and January — was just 1.71 inches, compared to the 4.46 inches that’s considered normal, National Weather Service Bay Area officials said. A year ago it was even worse: February 2020 brought no rain to San Francisco.
It’s time to hope for a “March miracle.” We badly need rain and won’t get much — if any — over the next week.
An enormous ocean current that flows between continents in a worldwide circuit that can take centuries to complete is slowing down, scientists say. And climate change may be partly to blame.
New research finds that the Atlantic Meridional Overturning Circulation, or AMOC — a major ocean system that ferries water and heat between the equator and the poles — is at its weakest point in more than a thousand years.
West Side farmers using the federal Central Valley Project can expect 5% to 75% of their contracted supply this year.
Two straight dry winters brought that announcement Tuesday from the U.S. Bureau of Reclamation. It involves water pumped from the Sacramento-San Joaquin Delta to as far south as Kern County.
