You know how monsoon storms will usually be intense for, say, 15 minutes, before calming down and, after a few fits and spurts, going away? Well, today's storm was intense, for say, 15 minutes, before getting more intense, and then adding some hail, and later calming down to merely intense.
That cycle continued for about three hours.
And the result, according to the National Weather Service, was a record. Forgive the all-caps; that's how the NWS rolls:
AS OF 430 PM...2.84 INCHES OF RAIN HAVE FALLEN AT THE TUCSON INTERNATIONAL AIRPORT TODAY. THIS IS A RECORD AMOUNT OF RAIN FOR SEPTEMBER 15TH.
THIS IS ALSO THE SECOND WETTEST SEPTEMBER DAY ON RECORD. THE WETTEST SEPTEMBER DAY ON RECORD WAS SEPTEMBER 10TH 1964 WHEN 2.85 INCHES OF RAIN FELL.
THIS IS THE FIFTH WETTEST DAY OF ALL TIME IN TUCSON.
HERE ARE THE TOP FIVE...
1. 3.93 INCHES JULY 29TH 1958
