California snow advisory for Sierra Nevada is earliest in 20 years



People traveling through the Sierra Nevada should make alternate route in case there are road closures, according to the National Weather Service.

California issued its earliest snow advisory in the past 20 years with an alert early this week for residents in the Sierra Nevada, according to the National Weather Service.

From Sunday to Monday, areas of the Sierra Nevada above 8,000 feet can expect some snow as a trough, a region of low atmospheric pressure, brings between a 35% to 65% probability of 2 inches of snow or more.

“We have a very cold draft moving into the area this afternoon and evening, and [it] will move through on Monday,” JP Kalb, a forecaster with weather service, told USA TODAY.

The trough will also bring rain to the San Joaquin Valley.

The winter advisory will remain in effect from 11 p.m. local time Sunday night to 5 p.m. Monday.

Slick roads

California’s State Road 120 passes through the Tioga Pass, an area near Yosemite National Park that is expected to receive more snow than other areas, according to the weather service. It is one of the main roads that leads to the park.

There is a 40% chance it will receive 3 inches of snow or more.

The pass, which is 231 miles east of San Francisco, is at an elevation of 9,943 feet in the Sierra Nevada and usually closes in the winter due to snowfall.

Visitors in areas of Yosemite National Park could experience snow as well.

Those traveling through the Sierra Nevada this week should have alternate plans in case of closures. People driving through the Valley should watch for slick roads.

Yosemite National Park will make the decision on whether to close SR 120, David Spector, a weather service meteorologist, told USA TODAY.

Second chance of snow later this week

There is another 40% chance the Tioga Pass will see 3 inches or more of snow from Wednesday to Thursday as a second trough moves into the area.

California Wildfires won’t be affected

Southern California is coping with several wildfires. However, they will not be impacted or lessened by the rain.

“Most of the wildfires are well South of where we have the advisory,” said Kalb.

The weather service forecasts the precipitation will be 33% to 40% below average. Last year was slightly below average.

Despite the early snow advisory, the weather service forecasts that the Missouri River Basin Drought, which is affecting areas of northern and southern California, could continue to worsen through September.

WOW Carwash touts year-round water conservation with recycling tech in Southern Nevada

WOW Carwash touts year-round water conservation with recycling tech in Southern Nevada


In the desert climate of Southern Nevada, WOW Carwash says it is working year-round to conserve water and reduce its environmental impact, using a combination of water-reclamation technology, biodegradable soaps and energy-efficient equipment.

The Las Vegas-born company says washing a car at home uses roughly 100 gallons of water. By comparison, WOW says it uses about 30 gallons per vehicle and reclaims up to 80% of the water.

WOW says its water-reclamation system exceeds typical local requirements. While local car washes are only required to have one sand and oil separator, WOW says it has four, along with a mud tank and UV filters designed to recycle water, reduce daily water use and ensure no solids are sent to the sewer system.

The company says all water from a WOW Carwash enters a 1,500-gallon mud tank underground at each location to begin separating soils from the water. From there, WOW says the water passes through a series of four sand and oil separators, where oils float to the surface, and soils sink to the bottom. WOW says the cleaned water is then pumped through UV and micron filters to remove remaining contaminants so it can be recycled and reused in the car wash.

WOW also says it repurposes the dirt washed off vehicles. The company says its water-reclamation tanks are pumped regularly by licensed vacuum trucks to maintain efficiency, and what is pumped out is then utilized as fertilizer.

WOW says all cleaning agents used in its tunnel wash process are environmentally safe and biodegradable, and that the soaps are safe to the human touch and for a vehicle’s paint while still being tough on dirt. The company says the cleaning agents break down naturally, reducing harmful runoff that could otherwise flow into storm drains and local waterways.

To reduce its carbon footprint, WOW says it uses energy-efficient equipment, including Variable Frequency Drives that allow electric motors to “ramp down” when demand is low to reduce electricity use during operations.
