Ivo on the loose!

In our last discussion on Sunday, we mentioned that there was a possibility of a tropical system off the coast of Mexico making its way north and perhaps bringing us a significant surge of moisture for late this weekend / early next week.  Sure enough, that situation is coming to fruition in the name of Tropical Storm Ivo.  Ivo’s not overly strong and won’t hold together for long once he hits land, but his decaying remnants are going to bring plenty of rain to Arizona, as well as Southern and Eastern Utah.  Check out this model-derived precipitation forecast for the next 5 days:

Notice the massive area of 1-2 inches of rainfall.  The big question is how much, if any, of this will make it up to SLC and surrounding areas.  My guess is we’ll get something, but it might not be much.  As for flooding potential, it’s there, but not as much as you might think.  This rain looks like it will be drawn out over a couple days and won’t fall as your typical summer downpours, so flash flooding isn’t as much of a concern as it might appear just by glancing at this map.  Still, slot canyons and burn scars should be avoided on Sunday and Monday.

Summer is still going strong, but this is at least an interesting weather event to break up the monotony of the hot, mostly dry weather we’ve been having.  Fingers crossed we get a good soaking all way up in Northern Utah!
