As low pressure intensified over western Utah, easterly canyon winds developed along the Wasatch Front, with severe winds and some property damage reported in the northern Wasatch Front.
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.
The episode as NWS SLC wrote it up.

NWS Salt Lake City, UT wrote its last area forecast discussion before the first event at Jun 12, 2:45 AM MST, 6 hours 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SALT LAKE CITY UT 345 AM MDT SAT JUN 12 2010 .SYNOPSIS...A COOL AND MOIST PACIFIC SYSTEM WILL CONTINUE TO SLOWLY CROSS THE WESTERN UNITED STATES THIS WEEKEND. WEAK HIGH PRESSURE WILL BUILD INTO THE AREA EARLY NEXT WEEK. && .DISCUSSION...A LARGE SCALE TROUGH WITH ATTENDANT LOW OVER THE FOUR CORNERS AREA WILL GRADUALLY SHIFT EASTWARD THROUGH THE WEEKEND. COPIOUS AMOUNTS OF MOISTURE PRESENT WITHIN THIS SYSTEM WILL BRING WIDESPREAD PRECIPITATION TO THE AREA TODAY INTO TONIGHT. EASTERLY FLOW ACROSS THE WASATCH MOUNTAINS WILL CAUSE GUSTY WINDS NEAR CANYON MOUTHS OF THE WASATCH FRONT AND THE CACHE VALLEY THIS MORNING. GUSTY WINDS ARE ALSO EXPECTED THIS MORNING ACROSS THE WASHINGTON COUNTY CANYONS. SEVERAL QUESTIONS LINGER WITH THIS FORECAST. FIRST AND FOREMOST...WILL FLOODING BE AN ISSUE ACROSS SEVERAL OF THE DRAINAGES OF NORTHERN UTAH. CURRENT RFC FORECASTS PUT BOTH CHALK CREEK ABOVE COALVILLE AND THE WEBER RIVER FROM THE UINTA MOUNTAINS TO ROCKPORT RESERVOIR NEAR FLOOD FLOW TONIGHT. FLOOD WATCHES ARE IN EFFECT FOR BOTH OF THESE WATERWAYS AS THE AMOUNT OF PRECIPITATION THAT FALLS ON THESE DRAINAGES WILL LARGELY IMPACT THE ACTUAL FLOW. PERSONS AND PROPERTY ALONG THESE DRAINAGES SHOULD BE PREPARED FOR POSSIBLE FLOOD FLOWS THROUGH SUNDAY. THE SECOND QUESTION IS THE TIMING OF PRECIPITATION TODAY AND TOMORROW. THERE IS NO SPECIFIC FEATURE TO FOCUS ON THIS MORNING INTO THIS AFTERNOON TO AID IN TRYING TO TIME PRECIPITATION OVER A PARTICULAR POINT. PREVIOUS SHIFT INCLUDED WIDESPREAD PRECIPITATION OVER JUST ABOUT THE ENTIRE CWA THROUGHOUT THE DAY AND INTO THE NIGHT. THIS TREND CONTINUED WITH THIS MORNINGS PACKAGE. AN UNSEASONABLY COOL AND MOIST DAY WILL BE THE RULE FOR TODAY ACROSS THE STATE. THE THIRD QUESTION INVOLVES A TROUGH MOVING ACROSS THE WEST THURSDAY INTO FRIDAY NEXT WEEK. MODELS HAVE BEEN RELATIVELY INCONSISTENT BOTH RUN TO RUN AND MODEL TO MODEL WITH THIS SYSTEM. THE 00Z EC KEEPS A RELATIVELY WEAK TROUGH AS ALMOST A BRUSH BY FOR THE CWA...WHILE THE GFS DEVELOPS A STRONG...DIGGING TROUGH ACROSS THE WESTERN UNITED STATES. THE RAMIFICATIONS TO THE FORECAST OF THE GFS SOLUTION VERSUS THE EC SOLUTION WOULD BE MASSIVE...WITH TEMPERATURE SIGNIFICANTLY BELOW NORMAL IF THE GFS WERE TO BE ACCURATE. DECIDED TO MODIFY THE CURRENT FORECAST VERY LITTLE AS THERE IS LITTLE CONFIDENCE IN EITHER SOLUTION AT THIS TIME. && .AVIATION...LIGHT WEST TO NORTHWEST WINDS ARE EXPECTED AT THE SLC TERMINAL THROUGH THE EARLY MORNING HOURS...WITH STRONGER NORTHWEST WINDS DEVELOPING AFTER 18-19Z. RAIN SHOWERS ARE EXPECTED TO END OR DECREASE SIGNIFICANTLY BEGINNING AROUND 11 OR 12Z...WITH CIGS LIKELY RISING ABOVE 6000FT AGL. SHOWERS ARE EXPECTED TO INCREASE AGAIN BY 17-19Z WITH CIGS LOWERING BELOW 6000FT...WITH A 10 PERCENT CHANCE OF MVFR CONDITIONS IN THE HEAVIER SHOWERS. && .FIRE WEATHER...A MOIST AIRMASS WILL SETTLE INTO THE AREA THROUGH THE WEEKEND AS A STORM SYSTEM CONTINUES TO IMPACT THE GREAT BASIN. THE STORM SYSTEM WILL FINALLY EXIT THE AREA ON MONDAY...MARKING THE BEGINNING OF A WARMING AND DRYING TREND. SOUTHERLY WINDS ARE EXPECTED TO INCREASE LATE TUESDAY INTO WEDNESDAY AS THE NEXT STORM SYSTEM APPROACHES THE AREA. && .SLC WATCHES/WARNINGS/ADVISORIES...
