A spring-like storm system passing through Utah brought gusty winds ahead of and just behind the cold front on March 22.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.

Area Forecast Discussion
National Weather Service Salt Lake City UT
930 AM MDT Thu Mar 22 2018
.SYNOPSIS...An increasingly moist southwest flow aloft will spread
northeast across much of Utah through tonight. A weak disturbance
embedded in this moist southwest flow will cross Utah tonight
through early Friday. A second cold upper level trough off the
Pacific Northwest coast will move east and impact mainly northern
and western Utah and southwest Wyoming this weekend.
&&
.DISCUSSION...Southwesterly flow prevails across the Interior
West this morning. The remnants of an embedded Atmospheric River
(AR) within this flow continue to slowly spread eastward across
the Great Basin, with associated moisture advection coupled with
orographic forcing allowing for periods of rain and high
elevation snow (above 9500 feet) across both northern and
southwest Utah. As large scale ascent increases this afternoon
through this evening in response to an approaching shortwave
trough, should see precipitation expand in coverage and intensity
across much of the forecast area.
Strengthening flow aloft coupled with a tightening pressure
gradient today should also allow winds across western Utah as
well as the higher terrain to increase. Gusts into the 40 mph
range have already been observed across the Dugway Mesonet and
will likely continue to increase into the afternoon hours. Going
High Wind Warning for the western valleys still looks on track.
The cold front associated with the approaching shortwave is
forecast to push into northern Utah after midnight serving as a
focus for heavy precipitation, and lowering the snow levels below
7000 feet. This front will quickly sweep out of the area Friday
morning allowing for a quick drying trend by afternoon. May need
to consider Winter Weather Headlines for the northern mountains
for tonight given heavy snow potential.
&&
.AVIATION...Gusty winds will continue to increase at the SLC
terminal through the morning. By afternoon, wind gusts in excess
of 40kts are possible. Ceilings are expected to fall to near 7000
feet after 17-18Z.
&&
.SLC WATCHES/WARNINGS/ADVISORIES...
UT...High Wind Warning until 9 PM MDT this evening for UTZ003-005-015-
016.
WY...None.

Gusts approaching 60 mph are possible across western Utah beginning late this morning and continuing through the first half of this evening. Scattered light showers across northern Utah and southwest Wyoming this morning will expand across the north during the day. Most of the precipitation will focus on the higher terrain today. Valley rain and mountain snow will increase across the northern portion of the outlook along a cold front moving slowly east across the area tonight. Significant amounts of rain are possible across the valleys of northwest Utah, with several inches of snow accumulating at the adjacent higher elevations overnight. Across southern Utah light rain will develop across southwest Utah later this morning, then becoming widespread and locally heavy across the southern third of the state this afternoon through the overnight hours. Snow will exist at the highest elevations of the southern mountains. Accumulating snows are expected, though mainly above 9000 feet. Areas rivers in southern Utah will see significant rises due to the expected moderate to heavy rainfall. River flooding is not expected at this time. Flash flood prone areas of southern Utah could see localized flash flooding late this afternoon through the overnight hours. .DAYS TWO THROUGH SEVEN...Friday through Wednesday Moderate to locally heavy valley rain and mountain snow will continue along the cold front over northern Utah early Friday. Widespread showers will also continue across southern Utah, with the heaviest precipitation heading into the Lake Powell area during the morning. The areal extent of precipitation will decrease during the day with only a few light showers remaining by early Friday evening. The main storm system off the Pacific Northwest coast will turn east and impact the northern half of the outlook area over the weekend. The colder air associated with this feature will bring lower snow levels to the north, with a few of the higher valleys and mountains receiving accumulating snows. Precipitation will shift south into southern and central Utah early next week, then end across the entire outlook area by Wednesday. .SPOTTER INFORMATION STATEMENT... Weather spotters are encouraged to report significant weather conditions according to standard operating procedures.
