All three of the main systems moving into the West Coast this weekend and early next week are expected to bring periods of heavy rain to coastal Southern California.
AccuWeather Global Weather Center – January 11, 2019 – Dry weather will be rare in California in the coming days, with an onslaught of storms expected to keep rain and mountain snow around through at least the middle of next week.
"The cumulative nature of the storms has the potential to bring well over a foot of rain to the west- and southwest-facing slopes of the Coast Ranges and at least a couple of yards of snow to the high country of the central and southern Sierra Nevada into next Friday," according to AccuWeather Senior Meteorologist Alex Sosnowski.
"As the pattern evolves and the storms hit with additional moisture, dangerous, damaging and life-threatening situations may arise due to the magnitude of flooding and mudslides unleashed," Sosnowski said. "The situation could escalate quickly."
One storm, perhaps the more mild-mannered of the bunch, is expected to impact coastal areas of Southern and Central California into Saturday afternoon.
While Los Angeles will likely receive nearly 0.5 of an inch of rain from this storm, it is not expected to be the heaviest rainfall of the week. All three of the main systems moving into the West Coast this weekend and early next week are expected to bring periods of heavy rain to coastal Southern California.
Conditions should be free of rain around Los Angeles as the Rams take on the Cowboys in the NFL playoff game during Saturday evening.
As with recent storms, flash flooding, mudslides and resulting travel delays can be expected. While a strong wind event is not in the works, periods of gusty winds could lead to downed trees and some property damage.
By Sunday night, a second system is on track to move into the state. This one will follow a similar track, mainly impacting central and southern portions of the state.
While the first storm will have a tough time moving far enough inland to reach the higher terrain of the Sierra, "the storm on Sunday through Tuesday will be strong enough to bring heavy snowfall into the Sierra Mountains," according to AccuWeather Meteorologist Brett Edwards.
