SOUTHWESTERN U.S. & MEXICO - More rain for the southwestern U.S. into Wednesday, forecasters say, with showers and thunderstorms venturing into California, Arizona, Northern Mexico, and even further east into Texas.

"The storm system over the southwestern U.S. is pulling moisture from more humid areas and into the region, resulting in a significant increase in activity," AccuWeather Meteorologist Evan Duffey said. "Showers and thunderstorms across the area will be scattered but some could produce rainfall rates of 1 inch or more per hour.” 

Thunderstorms will be spotty throughout the Southwest, but the slow moving nature of the system may lead to rounds of thunderstorms hitting the same areas for multiple days, AccuWeather reports. Residents and growers in the regions should also keep an eye out for potential flash flooding, Duffey continued. 

While the showers and thunderstorms will mainly be concentrated in the four corner states, this storm system will produce spotty showers across the southeastern portion of the state California as well, leaving the potential for some flooding and muddy terrain.

Duffey also expects the system to collide with a tropical system as it moves into the western Gulf of Mexico.

"The combination of the energy of the Southwest system, with the large swath of moisture moving inland from the Gulf, should lead to widespread heavy rainfall over New Mexico, Texas and the surrounding region,” he continued.

While this specific storm will not put significant dent in the drought, as we’ve previously reported, California and its surrounding states are expecting significant precipitation through winter due to El Niño.
