As the Valley dries out from a round of intense storms, agencies across the region are keeping a close eye on the sky.
"This is definitely what we'd call a significant event...widespread rain, flooding," said Meteorologist Daniel Henz with the Flood Control District of Maricopa County.
The Flood Control District of Maricopa County keeps tabs on flooding-related issues. During Monday's storms, they saw hundreds of rain gauges across the Valley begin to fill up. Some areas saw more than an inch, or even more than two inches of rain.
"Municipalities then start getting notified, all their local emergency managers, fire, police chiefs, we're giving them the information about where the flooding is going so then they can help protect the public," Henz said.
Henz says while Monday's storm wasn't a surprise, it did present a challenge.
"We knew Central Arizona was at risk for severe weather and flooding -- it's just who's going to get hit the hardest?" he said.
Henz told ABC15 the agency collects data, which can be useful to local municipalities in deciding future projects.
"Sometimes it takes really big rain and flooding events to really know and characterize what actually may need to get done or where there may be some problem areas," he said.
"So events like what we saw in 2014, 2016 and even this event yesterday may end up helping shed some light to local municipalities on some areas they may want to work on."
More rainfall is expected on Wednesday and Thursday, so flooding continues to be a concern with ground already saturated.
