Interactive Display For ALERT Data


Nice sunrise this morning, after a mostly suppressed and dry day yesterday.

Many thanks to Jeff Beamish for sending me the following info yesterday.

Good morning Bob!

Just read your blog post this morning & noticed the rainfall map from yesterday. Not sure if you’re aware, but the county did a major upgrade to its rain gauge map. Here’s the link: http://alertmap.rfcd.pima.gov/gmap/gmap.html

Enjoy!

I had not been aware of this upgrade since I usually click directly to the precipitation page. The new, interactive display appears very versatile. Specific details can be found at the Pima County Flood Control District page -



Yesterday's thunderstorm activity, as indicated by detected CG flashes, is shown above (from Atmo and Vaisala) for 24-hours ending at midnight last night. Storms were much more restricted to higher elevations than they were on Wednesday.

Below is new ALERT display showing precipitation during 24-hours ending at 7:00 am MST this morning. I had been hoping for a display such as this for a number of years. One can quickly determine that only 15 of the 93 sites had rainfall yesterday and that these were at higher elevations. The Tucson metro area basically had 0% coverage - the first dry day here at the house since the 25th of July.

Two other display options are shown below - very nice upgrade!

The ALERT data provide an excellent means for the NWS to evaluate and verify it's grid box precipitation forecasts and also for model verification.
