Monsoon Storms Producing Heavy Rain in the West
The monsoon season is well underway in the West and a strong push of moisture will deepen across the region today, bringing the potential for very heavy rainfall. This will create an
environment supportive of flash flooding during the afternoon and evening. On Sunday, several storms produced heavy rain, especially in Arizona.
Flash Flood Watches continue in portions of California, Nevada, Utah, Arizona and Colorado. Heavy rainfall can lead to rapid onset of flooding, with some of the most prone areas being slot canyons, burn scars, normally dry washes, and low water crossings. Water can rise quickly downstream of heavy rain, even when the actual thunderstorm is many miles away. Rock and mud slides, as well as water flowing across roadways, will be possible and could locally impact travel.
Rainfall totals of over an inch are possible in the heaviest thunderstorms into this evening. Storms will remain robust most of the night, diminish overnight.
