The Pima County Regional Flood Control District is advising the public to use extreme caution when traveling through the region, as strong storms are expected throughout southern Arizona.
Forecasts from the National Weather Service show an increased chance of strong thunderstorm development and heavy rainfall beginning Thursday, July 22.
Weather predictions are difficult to make with certainty, however, the current information available indicates that a significant low-pressure disturbance could move slowly across the state, from east to west, bringing with it chances of multiple days of heavy rain and flash flooding through Saturday night.
This storm system is a nearly identical weather pattern to the powerful storm system from the 2006 monsoon.
