The Afternoon Deluge

Monsoon thunderstorms developed over the Salt Lake Valley this afternoon and brought heavy rainfall to the northeast corner of the Salt Lake Valley, especially the University of Utah. 

The event started with the development of a cell over or just downstream of the Salt Lake International Airport.  This one moved off over North Salt Lake.  Shortly therafter, two cells formed just to the south of the track of the first cell and pounded the Avenues and Avenues Foothills.  

Then things got interesting as a cell exploded west of Murray and moved northeastward to the University of Utah.  This was the beginning of a series of training storms that pounded the area around the U before things settled down.  The full sequence is below.  I'm hoping the video will upload properly as I'm working with some limitations currently.  

Storm total Radar precipitation estimates through 2200 UTC (1600 MDT), which does not quite capture the entire storm period so expect these to go up a bit show more than an inch of rain in a SW to NE oriented band from just north of Taylorsville to the foothills above the University of Utah.

Maximum accumulations of > 2" were centered on Dry Creek Canyon and Mt. Van Cott, pretty much over and just north of the burn scar above the U hospital.

Some transport of falling rain can occur below beam elevation, so exactly where this rain fell on very small scales is hard to say, but this does appear to have been a significant stress test for flash flooding in the burn scar area.  

As I type this, I don't have access to estimates through the end of the storm or information on the burn scar.  Hopefully it held up as that would be a significant victory.
