FILE - In this July 25, 2017, file photo, rafters float down the Colorado River near Moab, Utah. Rivers are drying up, popular mountain recreation spots are closing and water restrictions are in full swing as a persistent drought intensifies its grip on pockets of the American Southwest. Climatologists and other experts are scheduled Wednesday, May 23, 2018, to provide an update on the situation in the Four Corners region - where Arizona, New Mexico, Colorado and Utah meet.
