As evening settles over the northern San Joaquin Valley, the National Weather Service’s Sacramento office issues a cautionary note for motorists, as temperature and dew point spreads tighten, leading to the formation of patchy fog in the region.
The focus of concern extends to areas along Highway 99, particularly north of State Route 120 near Manteca. Commuters and travelers traversing this route, especially overnight, are urged to exercise heightened caution due to the potential for reduced visibility caused by locally dense patches of fog.
While the fog is not anticipated to be widespread across the region, the tightening temperature and dew point spreads create favorable conditions for its formation, emphasizing the need for vigilance on the roads. The National Weather Service advises drivers to be prepared for rapidly changing visibility in localized areas, and to adapt their speed and driving habits accordingly.
