Monsoon

We are in the midst of our monsoon season. It is a wet monsoon because a shift in our winds brings moisture from the Gulf of Mexico to our region. The pattern of our storms is for them to develop in the late afternoon and to dump heavy rainfall, accompanied by high winds over a relatively short period of time. Our monsoon season lasts from early July into September. We get more than half our annual rainfall during this period.

Our monsoon storms are hit and miss. Some areas of town are hard hit and others, even those nearby, get missed. More rain falls closer to the mountains than down in our valley.

We had the first big storm of the year in our part of town last night. It started at about 7 pm and lasted a couple of hours. I think we got around an inch and a half of rain.

Heavy rainfall here in the desert fill the natural drainage ways quickly. They can create dangerous situations.












In fact, we have a law called the Stupid Motorist Law, that was named for the boneheads who try to drive through the flooded washes.



The owner of this car was caught in the Alamo Wash last evening. I don't know if this car was pulled out or made it this far before dying. I parked my truck, seen in the background, at the bottom of the wash. You can see how deep the water can get at this crossing.




Trees are among the casualties of the high winds. Non-native trees, like this California Pepper tree are more susceptible to wind damage than native plants.

People here plant the California Pepper tree because it tolerates drought and poor soil. The tree does well here, right up to the time that they succumb to the high winds. Then it becomes clear that planting this tree wasn't a great idea.

The tree has two big problems. First, its roots are shallow, because it has adapted to catch water quickly. Secondly, it doesn't drop its leaves in drought conditions. Instead its branches hollow out to minimize the need for water. Both adaptations contribute to the plant falling victim to the wind.

You can see the shallow roots in the picture. This tree snapped off at ground level.

The forecast was for more rain this afternoon, but it didn't materialize, at least in our neighborhood.

It is cool that you got out of your truck and walked around taking pics. Getting in the habit of taking your camera everywhere?

Very floody outside here today, summer can be so unpredictable--or it just seems more unpredictable than the other seasons. Yesterday I was watering my roses & herbs because it seemed they were sitting in dust, and today there are pools of water around them, and the rain continues.
the weatherpeople aren't that helpful.

Interesting! I had no idea you all EVER have rain!

I'm conflicted about Tammy Faye. Sure, she was a master manipulator, but I also think she got smarter as she got older. I don't love her, but I don't dislike her nearly as much as I used to.

You grew up in Nebraska? That seems like it is worth a post or two. Weren't a lot of magician/ talk show guys from Neb? Carson? Cavett?

I drove thru once. It's a long way from one end of neb to the other in 90 degree weather.
