Tropical Storm Newton, which downgraded from hurricanes status on Wednesday, has already slammed Mexico, and it's set to hit Arizona on Wednesday.

What it means for the US
Newton isn't officially a hurricane anymore, but the real danger might come from floods, rockslides and mudslides in mountainous areas. AccuWeather reports some areas may see two months' worth of rain in a few hours.
In Arizona, Tucson is right in the heart of the storm's path, and Phoenix is just on the edge of the forecasted path.
After Wednesday, the storm is expected to turn northeast from Arizona into New Mexico.
Here's AccuWeather's forecast track for the storm.
