Yesterday Morning's Heavy Rain Event

First - regarding the post just below. I have taken a close look at the webcam views to the north. The fast-running loop from Atmo made it appear that a construction crane collapsed. However, the crane is back this morning, so it was apparently rapidly lowered by folks at construction site as the storm front approached.

The heavy rain event unfolded yesterday morning as storms developed northward over the metro area. The ALERT Network map above is for the 24-hour period ending at 7:00 am MST this morning. Areal coverage is 87 sites of 93 with rainfall.I count 22 sites with greater than an inch.

Here at the house we received 2.84 inches of rain, most of which fell from 8:30 to 9:30 am. This was the heaviest rainfall in a day or less since I started records here in 1999. There have been 5 other days during the years with amounts of 2.00 inches or more - heaviest of those was 2.32" on August 13th 2008.

There were six high-water rescues in the City but apparently no injuries or deaths.

The new version of Pima County's ALERT Network precipitation maps appears not to allow the user to examine the past 12-hours, nor to select specific periods of data. I show below the metro west sector of the network for the period 7:00 pm through 7:00 am this morning. The event was well over by evening. This is also illustrated by the plot of detected CG flashes at bottom (from Atmo and Vaisala) for 24-hour period ending at 1:00 am this morning. The green tones indicate flashes that occurred during the morning yesterday.

I am hopeful that some of the key aspects of the new ALERT display can be upgraded so that the data base can be easily accessed for past periods in support of research efforts. If I have missed these capabilities in the new system, someone please send me a heads up.
