As west of the rockies turns into more of a desert than it already was, east of the rockies will likely flood more with hurricanes. Why?

This is one of the features of Global warming as things change in fits and spurts from extreme heat in summers to winter cold in places like Texas and even northern Mexico that were not like this before. I feel very lucky indeed at this point to live somewhere on the northern California Coast that is known for temperatures 60 to 70 degrees most of the summer along the coast because of the heat inland drawing the fog and evaporation off the ocean onto land to at least 5 to 10 miles (if not more inland) more the hotter it gets often to places like Hollister and Morgan Hill and sometimes further inland than that.

So, as the rest of the western United States bakes we still don't have air conditioners mostly where I live. Like maybe on a fluke you might get one day per year in the 90s Fahrenheit or even on even rarer exceptions during a Santa Ana Wind condition we might get one day every few years of 100 degrees. But, most of the summer it is always 60 to. 70 degrees as the high even in June, July and August of most years.

But, in some ways no matter where you live on earth now you could (if you are not prepared) die of extreme heat or extreme cold where it wasn't that way before in previous years. One of the reasons is heat waves used to only be around 2 times a year in the 1960s. However, now there are at least 6 heatwaves a year which means people without air conditioning are more likely to die in these heat waves worldwide now than before. 

But, I think it's very important for people on the east coast to also understand that the heat out here in the west is usually not humid unless a thunderstorm is going by dropping rain and lightning. IT is very very dry summers from the Rockies westward. 

Because of this people can actually survive (without air conditioning for awhile) in temperatures up to 120, 125 to 130 degrees if they are young healthy and very careful of what they are doing. You can get places so dry (the air) that we get (especially in the deserts) humidity readings of 5, 10 or 20%. 

However, the problem becomes the fires in winds at these humidity readings because weeds and shubbery and trees are so dry at these humidity readings (especially in these constant temperatures above 90 or 100 that trees can just literally explode like Eucalyptus trees from Australia often do wherever they are planted in drier areas during a fire here in the U.S.

It's one of the reasons fighting fires is so very dangerous in Australia is when fire hits Eucalyptus forests the trees start exploding and can injure or kill firefighters unless they are trained to deal with this problem.
