The region is predicted to have above 30-year normal temperatures this summer; the precipitation outlook is mostly neutral but a bit unfavorable in the corner closest to Texas. Of course this is an area that is normally dry and has very sporadic rainfall.

UPDATE: All-time heat records are at risk in Arizona, Nevada and the California desert region over the next week.

  2. They are okay. But I venture most of the map should be green. Yellow is dry enough that campfires are forbidden.

    The formal definition of "extreme" fire danger boils down to "if a fire gets started it will be too hot to put out"

    Extreme (E):
    Fires start quickly, spread furiously, and burn intensely. All fires are
    potentially serious. Development into high intensity burning will usually
    be faster and occur from smaller fires than in the very high fire danger
    class. Direct attack is rarely possible and may be dangerous except
    immediately after ignition. Fires that develop headway in heavy slash or
    conifer stands may be unmanageable while the extreme burning
    conditions last. Under these circumstances the only effective and safe
    control actions are on the flanks until the weather changes or the fuel
    loading decreases.

    "Extreme" should be very rare, don't you think?
