Update: Spring Begins With An Atmospheric River
An “Atmospheric River” is taking aim at California.
The National Weather Service has issued a Winter Storm Warning for the Sierra Nevada until 11 PM Thursday.
Snow levels remain mostly above 8,000 feet, but will lower to 6,500 feet by tonight.
Additional snow accumulations will range from half-a-foot to four feet above the 6,500 foot elevation.
Plan on difficult travel conditions. Damage to trees and power lines is possible. Significant reductions in visibility is likely.
Additionally, a Flash Flood Watch has been issued for the Sierra Nevada, from noon today through Thursday evening.
The Atmospheric River will bring substantial rain to the foothills and mountains below 8,000 feet.
Heavy rainfall, in addition to snow melt, will create excess runoff and bring a threat of localized flash flooding, mud slides, rock slides and debris flows, particularly in the vicinity of the Detwiler Fire burn scar.
Some roads may become impassable or become washed out. Residents should be alert for rising waters on area streams with the possibility of flooding.
A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a VERY DANGEROUS SITUATION. You should be prepared to take action should Flash Flood Warnings be issued.
A Winter Storm Warning for snow means severe winter weather conditions will make travel very hazardous or impossible. If you must travel, keep an extra flashlight, food and water in your vehicle in case of an emergency.
