Event narrative

Visibility below a quarter mile was reported in Hanford.

Wider weather episode

As high pressure strengthened over the area on November 25, stronger radiational cooling took place on the morning for November 26 allowing for widespread dense fog to form in the San Joaquin Valley and prompted the first Dense Fog Advisory issuance of the season as travel on State Route 99 was adversely impacted by the fog. Fog reducing visibility from 1/16 to 1/8 of a mile was widespread by sunrise. The fog slowly burned off during the late morning hours and had completely dissipated by noon.
