Multiple systems will continue to impact the West into this coming weekend, NWS warns. Heavy lower elevation rain across central and southern California will continue a high risk of flash flooding into tonight with the possibility of mudflows near recent wildfire burn scars. The western mountains will continue to receive heavy snow.
The big thing that will make weather headlines through the end of the week will be the ongoing atmospheric river event affecting California, NWS forecaster Hamrick notes.
A strong storm system approaching the coast will have an anomalous surge of tropical moisture surging inland ahead of the cold front, he added.
There is a high risk of excessive rainfall on Thursday for the southern California mountains, capable of causing flash flooding and mudslides.
Farther to the north, the Siskiyou Mountains and the Sierra Nevada will get hammered with very heavy snow and blizzard conditions, with snowfall totals in excess of 30 cm (3 feet) for the higher mountains. Heavy snow is also in the forecast across the central and northern Rockies.
