Dense Fog in San Joaquin Confluence, California

Webcams showed very low visibility in Los Banos. Several school districts either opened late or delayed bus service.

An upper level ridge prevailed over the area January 6 and 7. Dense fog formed parts of the San Joaquin Valley during the evening of January 6 and expanded throughout much of overnight as light winds and inversion conditions in the valley were favorable for dense fog which resulted in traffic being paced by law enforcement and several school districts either opening late or delaying bus service. The fog lifted into a low cloud deck by early afternoon, but many areas did not clear out until the following day.
