Fire Weather Planning Forecast for Southwest and South-Central
Arizona and Southeast California
National Weather Service Phoenix AZ
227 PM MST Thu Apr 27 2017

...RED FLAG WARNING IN EFFECT FRIDAY DUE TO STRONG WINDS...LOW
RELATIVE HUMIDITY AND HIGH TO VERY HIGH FIRE DANGER...

.DISCUSSION...
Very dangerous critical fire weather conditions will exist Friday
for most districts as strong gusty west winds develop over the
area. This will be in concert with humidity levels below 15% by
late afternoon. In addition, scattered thunderstorms are possible
over southern Gila County where wetting rain could be very
limited. Therefore, a few lightning strikes could conceivably
initiate new fire starts if rainfall is minimal.

...Thunderstorms imply gusty winds...

Note...Additional Fire Weather Forecast information can be found
in the Area Forecast Discussion. See product PHXAFDPSR.
