According to the weather service, there is a difference between a watch and an alarm. The watch is issued when conditions are favorable for a specific hazardous weather event. For example, a flood watch is issued when conditions are favorable for flooding. A flood warning is issued when or when floods occur.
According to the Meteorological Service, areas affected by wildfires can be seen flooding.
“Even in Gila County, as we have seen in the last two months, it did not take much rainfall for the areas burned by the wildfires to flood down,” said meteorologist Andrew Deemer.
1 to 2 inches of rainfall was recorded from Flagstaff to the White Mountains along the Mughal Rim. According to the weather report from the National Weather Service in Flagstaff, most counties in Mojave, southern Cocono and most of Apache, Navajo and Gila have recorded the highest rainfall so far.
Although flash flood warnings are still being issued across northern Arizona, some counties may not receive rain.
“Part of your home or valley may be dry, and conditions across the town may be completely different,” Deemer said.
