(KTXL) — California is bracing for a new atmospheric river that will bring rain, winds and the threat of flooding, all while many communities dig themselves out of several feet of snow from earlier storms.
The new atmospheric river is described as a “warm” one, with the potential to melt freshly fallen snow in the foothill regions, sending dangerous quantities of snowmelt and rain down the creeks and rivers that traverse the state.
