...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHERN
UTAH...NORTHERN ARIZONA...AND FAR SOUTHEAST NEVADA...

An Elevated risk area has been added for portions of the southern
Sierra Nevada and western Transverse Ranges in southern California.
RH is somewhat marginal for the area, with a minimum of 15-25%
expected. However, strong winds (40-50 mph gusts with higher gusts
in mountain gaps), rapid drying of fuels, poor overnight RH
recovery, and observed rapid growth of the Post fire indicate the
threat for additional fire activity in the area. Otherwise, see the
previous discussion for further details.

.PREV DISCUSSION... /ISSUED 0151 AM CDT Sun Jun 16 2024/

...Synopsis...
A deepening western trough will bring an increase in southwesterly
flow across much of the desert Southwest this afternoon. Fuels in
this region have seen significant drying after several days of warm
and dry conditions. Guidance indicates fuels in this region are
critically dry, with recent ERCs data indicating 90th percentile for
dryness across much of northern and central Arizona. This is further
supported by active recent fire activity in this region. Relative
humidity reductions to 5-10 percent will overlap sustained winds
15-20 mph across central/northern Arizona, southern Utah, and far
southeastern Nevada where a Critical delineation was maintained with
this outlook. Outside of this region, a more broad area of Elevated
fire weather conditions will be possible across much of
central/southern Utah into southern Arizona, where there is less
confidence is sustained Critical wind speeds.

Elevated conditions may also extend into portions of western Nevada
in the lee of the Sierras. In this region, afternoon relative
humidity reductions to 15-20 percent will overlap sustained winds
10-15 mph (locally higher) amid modestly receptive fuels.
