Aviation Forecasts Discussions (AFD) INFO


    South-Central Arizona including KPHX, KIWA, and KSDL:
    Southwest winds gusting 20-25 kts will can be expected through at
    least 01Z before slowly weakening and trending toward familiar
    drainage patterns after 06Z. Above the surface, winds will remain
    westerly. Anticipate reduced slant visibilities the rest of the
    afternoon due to lofted dust wafting in from the California
    deserts. Otherwise, over very minor cirrus.
    Southeast California/Southwest Arizona including KIPL and KBLH:
    Very strong westerly winds (gusting 35-45 kts) will continue over
    Imperial County the rest of the afternoon before beginning to
    weaken after 03Z. Expect areas of blowing dust and sand causing
    reduced visibilities below 3SM with brief/localized reductions
    below 1 mile (near open desert). Winds will be lighter over
    Riverside County and southwest AZ. However, blowing dust will
    waft over these areas as well (most notably the Interstate 8
    corridor). Northerly winds at the surface and aloft begin to
    develop toward morning Saturday. Expect some moderate gustiness
    over the Lower Colorado River Valley after 16Z. Otherwise, only
    very minor cirrus.
