A near-hurricane is set to hit the Southwestern United States, in an anomaly so unheard of, one might wonder if we aren’t headed toward some apocalyptic new paradigm of bad weather.
Millions of people who have no idea how to deal with heavy rain at all, in the middle of the desert will get blasted by this Tropical Depression on Tuesday.
Right now it is dumping what is referred to as torrential rainfall on the Mexican state of Baja California. The storm is expected to leave 6 to 10 inches of rain there, as reported by the National Hurricane Center.
Baja California is a thin peninsula that probably won’t affect the motion of the tropical depression much, as by just Tuesday afternoon Rosa will be headed for Arizona: the middle of the American desert in the Southwest.
“Rainfall will be heaviest today and tonight into Arizona,” meteorologist Dave Hennen said. “Flash flood watches cover nearly 9 million, including Phoenix north to Salt Lake City.”
According to CNN, “As Rosa trudges northeast, the storm will dump 2 to 4 inches of rain on much of Arizona and up to 6 inches in the mountains. And given Arizona’s terrain, heavy rainfall poses an unusual set of problems. The National Weather Service’s office in Flagstaff warned residents to avoid the state’s famous slot canyons and any campsite near creeks. Forecasters there stressed that ‘just because it’s not raining where you are doesn’t mean it won’t flood.’”

The terrain of Arizona is basically untouched by heavy water, which would make a ton of water brought by a storm like this devastating. The canyons, creeks, and other features of the area aren’t prepared for this. In Flagstaff, Arizona the National Weather Service’s office warned residents to avoid the famous slot canyons of Arizona and campsites located near creeks.
It was noted that the deluge resulting from this storm could produce “life threatening flash flooding,” as reported by a weather authority people cite. “Dangerous debris flows and landslides are also possible in mountainous terrain,” the authority continued.
It’s beyond unusual for the Southwestern United States to get hit by a hurricane or tropical storm, to say the least.
Unusual tropical storms and hurricanes are reported in the mainstream to be a result of global warming or climate change. Other theories about the anomalous weather exist. A CNN meteorologist named Gene Norman was cited as saying “these events have begun to increase in recent years.”
A federally funded agency known as the National Center for Atmospheric Research had an expert say something about global warming contributing to tropical storms. Their senior scientist Kevin Trenberth said research indicates global warming is contributing to tropical storms becoming “more intense, bigger and longer-lasting, thereby increasing their potential for damage.”
With the chance of thunderstorms and heavy rain this afternoon, our Flash Flood Watch continues through Wednesday morning. If you encounter a flooded roadway remember to turn around, don’t drown. #azwx pic.twitter.com/sF3dADq5EX

The meteorologist said there wasn’t exactly solid evidence to suggest global warming, but “it is possible that this could be a side effect of climate change.”
“Warmer oceans are allowing eastern Pacific storms to reach higher latitudes,” Norman continued.
“This was not the case earlier. It was quite rare for an eastern Pacific storm to even reach Baja California, and this is now becoming more common.”
