Thank you Valentine Weather
Good report. Surprised Phoenix Monsoon is under 3".
I was in Arizona when the tornado outbreak happened back in Oct. 2010. That was one of the more unusual weather events with 9 tornados tracking south to north across the mountains.
Yes I remember that year too, a strong cut low dived down into Arizona and interacted with residual Monsoon Moisture and we had a severe outbreak of thunderstorms over Phoenix on Oct 5th, 2010 this led to super-cell thunderstorms that dropped up to golf ball size hail on parts of Phoenix and the next day Oct 6th the headed north in Northern Arizona and lead to the Tornado outbreak.
Late September early October can bring interesting Weather to the Southwest as we transition from the Monsoon season pattern to a fall winter pattern if the elements set-up right storms from the Pacific interact with the remaining Monsoon Moisture and we get severe weather.
Hurricane Rosa fell on an interesting anniversary the flood of 1983 in Southern Arizona when I lived in Tucson. A low pressure in-acted with the remnants of Tropical Storm Octave which led to flooding rains across Southeastern Arizona. It had been a very active Monsoon and then
I received 6.25 inches on Oct 1st and 1.50 inches on Oct 2nd several rivers jump their banks and flooded the small mining towns of Duncan and Clifton and Morrenci in SE Arizona and a bridge on I-19 south of Tucson was almost taken out that was a quite a storm.
These events are not uncommon this time of year and once about every 5 years we get hit hopefully it is a good sign of the expected " El Nino" these events tend to happen during those years and we badly needed the rain as we just offically finished the last water year ending Sept 30th with only
3.63 inches about (4.40) below normal.
