Winter Storm Warning Announced as 28 Inches of Snow, Dangerous 40 mph Winds Approach

The National Weather Service issued a new winter storm warning as parts of California are set to be hit with heavy rain and snow in the coming days.

"A lead mid to upper level trof will move into central California Thursday, followed by a much stronger system strengthening off the northern California/Pacific Northwest coast Friday and Saturday," the National Weather Service said, while revealing the potential for "heavy rains" along the California Coast Ranges and through the Sierra Thursday.

Those rains pose the risks of flooding across areas that have already seen much above average precipitation over the past few weeks.

Southern California Set to Receive Heavy Rain and Snow

The National Weather Service revealed Southern California will see the greatest risk of flooding.

"There will be a brief respite to heavy rains across California early Friday before the strengthening storm off the Northern California/Pacific Northwest coast sends additional heavy precipitation into Central to Northern California and southwest Oregon late Friday into early Saturday, with an increasing flood risk for northwest California at this time," the NWS said.

While heavy rains are expected, the NWS is also calling for up to 28 inches of snow and 40 mph winds in the Sierra Nevada Mountains near Yosemite National Park.

The cities of cities of Shaver Lake, Devils Postpile, Wawona, Tuolumne Meadows, Florence Lake, Huntington Lake, Cedar Grove, Lake Thomas Edison, and Lake Wishon were all hit with a weather warning ahead of the storm, which is expected to hit from early Saturday morning into Sunday.

The National Weather Service warned that "travel could be very difficult to impossible" and drivers should "slow down and use caution while traveling."
