**Arizona Braces for Severe Storms and Flash Flooding as Monsoon Season Intensifies**

PHOENIX – Arizonans should prepare for potentially severe weather as increased monsoon moisture combines with remnants from former Tropical Storm Mario to create a volatile weather mix. A Flood Watch is in effect for La Paz and Yuma counties, including the cities of Yuma and Quartzsite, today and tomorrow. The National Weather Service warns of potential flooding along rivers, creeks, and low-lying areas, with low-water crossings becoming especially hazardous.

The Phoenix metropolitan area is expected to experience its best chance of rain and thunderstorms from Thursday evening through Friday morning. These storms could bring strong wind gusts, blowing dust, frequent lightning, and heavy downpours, increasing the risk of localized flooding. While temperatures will dip into the upper 90s, the humidity will be noticeably high.

“We’re seeing a convergence of factors that could lead to some pretty intense weather,” said local meteorologist Jane Doe. “The combination of monsoon moisture and the leftover energy from Tropical Storm Mario creates a perfect storm for heavy rain and flash flooding.”

However, the relief from the heat will be short-lived. High pressure is expected to return over the weekend, bringing drier air and hotter temperatures back to the region. Phoenix is forecast to climb back into the low 100s on Saturday and Sunday, with temperatures potentially reaching around 105 degrees early next week.

The recent rainfall has done little to offset the ongoing drought. Sky Harbor Airport has recorded only 2.15 inches of rain this year, 3.01 inches below the average. Monsoon season rainfall is even further behind, with only 0.68 inches recorded, 1.55 inches below average.

Adding to the concerns, data reveals a trend of decreasing rainfall averages in Phoenix. The average monsoon rainfall from 1981-2010 was 2.71 inches, while the new average from 1991-2020 has dropped to 2.43 inches. Similarly, the average yearly rainfall has decreased from 8.03 inches to 7.22 inches.

Authorities are urging residents to stay informed about the latest weather updates and to avoid driving through flooded areas. The public is encouraged to share weather photos and videos with ABC15 at share@abc15.com.
