Tule Fog

Tule fog ( /ˈtuːliː/) is a thick ground fog that settles in the San Joaquin Valley and Sacramento Valley areas of California's Great Central Valley. Tule fog forms during the winter and early spring (California's rainy season) after the first significant rainfall. The official time frame for tule fog to form is from November 1 to March 31. This phenomenon is named after the tule grass wetlands (tulares) of the Central Valley. Motor vehicle accidents caused by the tule fog are the leading cause of weather-related casualties in California.

Famous quotes containing the word fog:

    The brown waves of fog toss up to me
    Twisted faces from the bottom of the street,
    And tear from a passer-by with muddy skirts
    An aimless smile that hovers in the air
    And vanishes along the level of the roofs.
    —T.S. (Thomas Stearns)
