KMSP - While the Desert Southwest is known for heat & sunshine, they are close to the Pacific Ocean and can occasionally get the remnants of a tropical system. In fact, last year, the remnants of 4 tropical systems pushed into the region dropping some much needed rain and actually helped the area finish above average in rainfall during the summer months for the first time in nearly 20 years. That may seem unusual, but the region averages the remnants of at least one tropical system every year. As often as that occurs, it’s rare that these storms keep their tropical storm or hurricane status all the way into the US. Well, it’s about to happen for the first time since Nora moved in just west of Yuma in 1997.
The current forecast has Newton entering the US just west of Nogales Arizona sometime Wednesday afternoon.
Nogales is about 150 miles southeast of the Phoenix metro. Because of the fast nature of this storm, the rains won’t last particularly long which should keep the flash flood threat to a minimum. That being said, as much as 6 inches of rain could fall on some of the eastern Arizona mountains which would be about 2 months’ worth of rain in roughly 24 hours. While the Tucson area could get 2 to 4 inches of rain, much of Phoenix will likely only end up with some scattered showers.
