Using the word "hurricane" in Arizona seems like an oxymoron!

OK thanks. Since I boycott the local news (sick and tired of the murder and mayhem stories and negativity) I had no idea.

Does anyone here have any insight as to what causes this monsoon in the desert? I think it is incredible that places in the desert can get more frequent rainfall, on average, than inland parts of Texas, which are more humid and closer to the Gulf. In fact, go up the mountains down in Mexico, and you will see rainfall frequency averages in July/August that rival the deep tropics.

Inland Texas is a rip-off compared to the desert Southwest; heat and humidity, but with no benefit.

The Gulf of California and the eastern Pacific of the coast of central and southern Mexico is where most of the monsoon moisture comes from. A little bit of the moisture also comes from the Gulf of Mexico. If there is a tropical system at the mouth of the Gulf of California moisture funnels right into Arizona due to the high and continuous mountains on both sides of the gulf.

Interesting. I notice that the DSW has very hot, dry Junes, which give way to much cooler (relatively) Julys. This makes me suspect some sort of "wind reversal" or "atmospheric change" that occurs during this time.

What happens is we have westerlies from October-June, but then July-Sep, the Subtropical Ridge moves north of us, and our winds come from the south, straight out of the Gulf of California, which has 85-90° shoreline temps in summer

Here is a pretty good link on it.

Like what Firebird mentioned, you get these domes of high pressure (rotates clockwise in the northern hemisphere) stuck over the four corners area in the summer, and it will start pulling in moisture from the south or southeast directly into Arizona. And if there is any tropical storm/depression/hurricane coming up the Sea of Cortez or west coast of Mexico, it will most likely be pulled into Arizona from the high pressure north of it.
