* WHAT...Thunderstorms will initially develop over the Mogollon Rim and other sky islands of Southeast Arizona during the early afternoon hours, then track southwest into the valleys of Southeast Arizona and become widespread during the late afternoon and early evening. The stronger storms will produce organized thunderstorm outflow winds between 40-50 mph, resulting in dense blowing dust with visibility between one-half and one mile and possibly a haboob with near-zero visibility. For the Extreme Heat Warning, dangerously hot conditions with temperatures 101 to 106 in Santa Cruz and Cochise counties and 107 to 112 elsewhere. Major to Extreme HeatRisk is expected. * WHERE...Eastern Cochise County below 5000 feet, Tucson Metro Area, Upper Gila River Valley, Upper San Pedro River Valley, and Upper Santa Cruz River Valley/Altar Valley. * WHEN...For the Extreme Heat Warning, until 8 PM MST Monday. For the Blowing Dust Advisory, from 2 PM to 8 PM MST Monday. * IMPACTS...Hazardous driving conditions due to reduced visibility. Heat related illnesses increase significantly during extreme heat events. * ADDITIONAL DETAILS...Warm overnight low temperatures of 84 to 90 degrees in the deserts will provide little to no relief from heat overnight. Warmest overnight low temperatures expected in the Western Deserts.

* WHAT...Thunderstorms will initially develop over the Mogollon Rim and other sky islands of Southeast Arizona during the early afternoon, track southwest into the valleys of Southeast Arizona and become widespread during the late afternoon, then move across the lower deserts of Southeast Arizona through the evening. The stronger storms will produce organized thunderstorm outflow winds between 45-55 mph, resulting in dense blowing dust with visibility between one-quarter and one-half mile and possibly a haboob with near-zero visibility. For the Extreme Heat Warning, dangerously hot conditions with temperatures 107 to 112. Major to Extreme HeatRisk is expected. * WHERE...South Central Pinal County, Southeast Pinal County, Tohono O'odham Nation, and Western Pima County. * WHEN...For the Extreme Heat Warning, until 8 PM MST Monday. For the Blowing Dust Advisory, from 4 PM to 10 PM MST Monday. * IMPACTS...Hazardous driving conditions due to reduced visibility. Heat related illnesses increase significantly during extreme heat events. * ADDITIONAL DETAILS...Warm overnight low temperatures of 84 to 90 degrees in the deserts will provide little to no relief from heat overnight.

* WHAT...Flash flooding caused by excessive rainfall is possible. * WHERE...A portion of south-central Arizona, including Santa Cruz, southwest Cochise and south-central and southeast Pima counties. * WHEN...From 2 pm MST Monday afternoon through 10 pm MST Monday evening. * IMPACTS...Excessive rainfall runoff may result in flash flooding of normally dry washes, roadway dips and other low-lying areas. * ADDITIONAL DETAILS... - The combination of an increase in lower-level moisture and an favorable weather pattern will result in widespread strong thunderstorms with heavy rain across portions of south- central Arizona. Although thunderstorms will initially develop over the higher terrain during the early afternoon, coverage is expected to become more widespread in the late afternoon and evening hours. Although most areas impacted by thunderstorms will receive only between one half to one inch of rain, isolated locations may receive between 1 and 3 inches. Excessive rainfall runoff will result in flash flooding. - Http://www.weather.gov/safety/flood
