Phoenix Sky Harbor didn’t see any major delays or cancellations. APS and SRP only saw a few thousand customers without power.
A rain gauge near McClintock Drive and McKellips Road saw nearly an inch of rain, while the neighborhood near the Loop 101 and Broadway Road saw nearly 0.80″ of rain.
It has winds of 80 miles an hour, but as it moves north into colder water and begins to move inland on the peninsula, it’s expected to start to weaken. In fact, no hurricane warnings are posted along the coast in Mexico, though Tropical Storm Warnings are up.
As the storm continues toward a possible glancing blow through southeast Arizona, it will only be a tropical depression with winds of 25 mph. There’s never been a hurricane that made landfall in Arizona.
