The atmospheric river storm hitting California this week presents a test for an experimental waste-capturing system that’s intended to keep plastic bottles, diapers and other trash from flowing into the Pacific. It has even captured a couch. The solar-powered system, designed to work mostly autonomously, was introduced in October at the mouth of Ballona Creek near Playa del Rey.
Wyoming, the Cowboy State, is at the other end of the Colorado River from the Imperial Valley. Its Green River starts high on the western slopes of the Wind River Mountains, and as the largest tributary to the Colorado River, plays a major role in sending us water 1400 miles away.
In a world getting used to extreme weather, 2023 is starting out more bonkers than ever and meteorologists are saying it’s natural weather weirdness with a bit of help from human-caused climate change. Much of what’s causing problems worldwide is coming out of a roiling Pacific Ocean, transported by a wavy jet stream, experts said.
A successive series of powerful atmospheric river storms poses a growing threat to California as the ground becomes more saturated, river levels rise and heavy winds threaten the power infrastructure. This week’s storms are expected to dump intense levels of rain in a fairly short period of time. The greatest potential for disaster is in Northern California, which has already been battered by several destructive storms — including one this weekend that caused a deadly levee breach.
Snowpack levels crucial to water supplies in the Colorado River basin have been rising over the past week as storms hit the Rocky Mountains. Dec. 27 measurements of 102% snowpack in the region — just above normal — had risen to 142% as of today in the Upper Colorado River Basin. That week-to-week change is good news but demonstrates the volatility of snowpack levels.
After three years of drought, California is beginning 2023 with more snow on the ground than at any start to a year in a decade. State water officials trekked into the Sierra Nevada to conduct the first snow survey of the winter season on Tuesday, reporting 174% of average statewide snowpack for the date.
Drenching rains forecast to pummel California on Wednesday and again over the weekend are poised to be the third and fourth major storms to march through in less than two weeks, raising the prospect of more misery in a season that has already brought flooding, debris flows and power outages to parts of the state. Over the weekend, rescuers scoured rural areas of Sacramento County looking for people trapped in homes or cars.
The cost of delivering safe, clean tap water to every household and business in a community is massive. In fact, it may be among the most expensive of all human undertakings. That is why only the wealthiest countries have achieved it at high rates and why 2 billion people on our planet still lack it.
More moisture-packed storms are expected to pay a visit to California during the first week of 2023 following an atmospheric river that dropped a historic amount of rain on the San Francisco Bay area as well as heavy snow in higher elevations on New Year’s Eve. Because of the saturated state of the ground, another atmospheric river during the middle and latter part of the week will lead to more flooding and mudslides in the Golden State, AccuWeather meteorologists warn.
As California enters what is expected to be a fourth year of drought, the State Water Resources Control Board is reviewing a request from environmentalists to suspend Los Angeles Department of Water and Power diversions from Mono Lake in the Eastern Sierra Nevada. In its request, the nonprofit Mono Lake Committee argues that the combination of drought and diversions from streams that feed the lake are exposing the lake bottom near islands that host one of the world’s largest nesting gull populations.
