This page serves as a holding tank for the maps and other materials discussed in our Southwest Drought Learning Network's Drought Discussion Podcast. Scroll down to the bottom of the page to find PDFs of the maps described in each podcast.
Episode 4 was recorded on August 12th 2022. Curtis Riganti from the National Drought Mitigation Center gives an overview of the National Weather Service's Climate Prediction Center's temperature and precipitation outlooks for the months of July, August and September over Arizona, New Mexico and the Southern High Plains. And Julie Elliott from the Natural Resources Conservation Service describes the Grass-Cast maps made on August 9th. Episode 5 for the August 23rd Grasscast maps is coming soon!

CoCoRaHS Precipitation Mapping
CoCoRaHS is a network of citizen precipitation observers. The CoCoRaHS website has a really useful map that is very handy for visualizing how much rain fell during a certain period of time at observer locations. Knowing how much rain has fallen at your location is very helpful for interpreting Grass-Cast predictions. If there is no gauge near your location, please reach out to the SW Hub to become an observer. We can supply a gauge.
