Wider weather episode

Following the departure of the winter storm which brought moderate to heavy precipitation and strong winds on February 4 and 5, a large upper trough moved into California during the morning of February 6 bringing with it another round of precipitation and gusty winds which continued until the morning of February 8. This system brought another half inch to an inch of rain to the San Joaquin Valley and 0.75 to 1.5 inches of liquid precipitation with 8 to 15 inchers of additional snowfall above 6000 feet in the Sierra Nevada. There were several reports of nuisance flooding as the ground was saturated by the previous storm at the onset of this storm. A fatal accident took place on SR 99 during the morning of February 6 as a result of the flooding. While winds were not as strong as with the previous system, several stations reported gusts exceeding 45 mph. The trough finally moved to the east of the area on February 8.
