occurring.

Excessive rainfall over the burn scar will result in debris flow 
moving through City Creek Canyon. The debris flow can consist of 
rock, mud, vegetation and other loose materials.

         Cottonwood Burn Scar in Piute County.

SOURCE...Law enforcement reported.

.KEY MESSAGES...

- High temperatures trend a few degrees cooler today, but
  overnight temperatures remain elevated across the region,
  yielding continued heat health impacts through Tuesday morning.

- A monsoonal surge has brought deep moisture across central and
  southern Utah today, and will become widespread across the
  region by Tuesday.

- Temperatures will gradually become cooler through the week with
  a daily threat for showers and thunderstorms capable of
  producing locally heavy rainfall through the remainder of the
  week.

.DISCUSSION...The strong ridge that brought us anomalously hot
temperatures across the region yesterday has shifted east and is
currently centered across the Dakotas. Southerly flow on the
western periphery of this ridge has brought an influx of deep
monsoonal moisture, especially across central and southern Utah
this afternoon. This increasing moisture and attendant
overspreading of clouds across the region has resulted in
temperatures cooling a few degrees for most of the area this
afternoon. A hot day is still in store for many across northern
Utah and southwest Wyoming with highs 100-105 degrees for many
lower valley locations and 95-100 across higher valley locations.
This increased cloud cover will also result in very warm overnight
lows across the region, which will exacerbate heat impacts through
at least Tuesday morning, especially for those without adequate
cooling or hydration.

Afternoon convective development will kick off this afternoon
across portions of central and southern Utah as PWATs rise to
0.8-1.2 inches across the area from the monsoon surge. Initiation
of storms is favored along the high terrain of the central and
southern Utah mountains, with coverage gradually expanding
northwest through the evening. Storms taper off by the late
evening. Any cells that develop through this evening will be
capable of producing locally heavy rainfall capable of producing
isolated flash flooding. Areas of highest concern include recent
burn scars (including the Cottonwood Fire), normally dry washes,
slot canyons, and steep terrain. Those outdoors this afternoon
across the area should have multiple ways to receive warnings in
case a flash flood threatens your area.

Deep monsoon moisture becomes widespread across the entirety of
Utah and southwest Wyoming on Tuesday, which will result in even
more widespread coverage of showers and thunderstorms. Again,
storms will be capable of producing locally heavy rainfall. This
deep moisture will linger across the region into at least this
weekend as the ridge remains stoutly in place through the period.
As such, expect continued chances for widely scattered showers and
thunderstorms with an increased risk for flash flooding each day
through this week areawide.

.AVIATION...

KSLC...VFR conditions are expected throughout the TAF period,
although visibility may be occasionally reduced slightly due to
smoke from nearby wildfires. West to northwest winds will return to
southeast around 03Z. There is a 20% chance outflow winds gusting to
25 kts push into the terminal from the south during the 00-03Z
timeframe.

REST OF UTAH AND SOUTHWEST WYOMING...Scattered afternoon showers and
thunderstorms will develop across southwest Wyoming as well as
areas south of I-80 this afternoon, developing across high terrain
areas and then drifting off to the northwest. Showers and
thunderstorms will be accompanied by gusty outflow winds and
lightning. Aside from this, winds will largely follow a typically
diurnal pattern at area terminals. Conditions expected to remain VFR
through the period, though any stronger storm directly atop a
terminal may result in brief reductions to CIGS/VIS. Smoke from
nearby wildfires will result in a hazy sky across northern Utah, and
occasional, slight reductions in visibility.

&&

.FIRE WEATHER...Hot and overall dry conditions prevail across most
of northern Utah today, though humidity will trend upward as
monsoon moisture continues to spread northward. Deep monsoonal
moisture is already in place across central and southern Utah,
which will allow for widely scattered showers and thunderstorms to
develop this afternoon. Convective development favors the central
and southern mountains, with coverage gradually expanding
northwest through the evening. Localized flash flooding will be
the main threat from any storms that develop today, with main
areas of concern being recent burn scars, normally dry washes, and
steep terrain. As deep monsoon moisture becomes widespread across
the state on Tuesday, daily chances for widely scattered storms
capable of producing localized flash flooding will continue each
afternoon and evening through the remainder of the week.
