.KEY MESSAGES, Issued 1044 PM MDT Sun Aug 9 2026...

  of Utah through the next five days. Expect an increased threat
  of flash flooding, primarily across slot canyons, normally dry
  washes, slick rock areas, and recent burn scars.

.DISCUSSION, Issued 1044 PM MDT Sun Aug 9 2026...
High pressure will remain in a favorable location to
continue the ongoing monsoon surge through at least the next seven
days across the Beehive State. First though, all remaining heat
headlines were allowed to expire earlier this evening.

Another round of showers and thunderstorms with the threat of
heavy rainfall will develop Monday afternoon across much of the
region. Again, like previous days, the most flood prone locations
will continue to be slot canyons, normally dry washes, slick rock
areas as well as recent burn scars.

Looking ahead, the Weather Prediction Center has Utah outlooked in
a marginal risk for flash flooding through the next 5 days...and
guidance suggests this monsoon surge should continue into at
least next weekend if not early next week.

.AVIATION...KSLC...The SLC terminal will see VFR conditions
throughout the day with some scattered clouds. Southerly winds are
expected to shift to the northwest between 19Z and 21Z. There is a
30 percent chance that showers in the vicinity of the terminal will
bring periods of gusty and erratic winds, with this most likely to
occur during the late afternoon and early evening.

REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions are expected
across the airspace throughout the day. Scattered showers and
thunderstorms will develop again later today, with the greatest
coverage in the late afternoon and early evening Pockets of heavy
rain and gusty winds may bring brief temporary MVFR visibilities and
ceilings that could result in temporary mountain obscurations.
Outside of showers and thunderstorms, generally light diurnal winds
can be expected. Locally reduced visibility in smoke will occur near
several large wildfires including near Richfield, near Cedar City,
near Morgan, and between Ephraim and Huntington.

&&

.FIRE WEATHER, Issued 439 AM MDT Mon Aug 10 2026...
High pressure will remain parked over the Four
Corners region through Wednesday. The resultant southerly flow
over Utah will continue to draw deep monsoon moisture northward.
This will result in showers and thunderstorms developing each
afternoon, focused primarily over the higher terrain, with the
storms becoming wetter as the moisture continues to move into the
lower levels. This pattern will bring improvement in relative
humidity values and an increasing chance of wetting rainfall,
though any storms that develop will be capable of producing gusty
and erratic thunderstorm winds as well as lightning. The ridge is
expected to move east for the latter half of the week, though a
relatively moist and unstable pattern is expected to remain over
the area for at least much of the remainder of the week.

.SLC WATCHES/WARNINGS/ADVISORIES...
