Even though the Atlantic hurricane season is certainly not very busy, the impacts from tropical cyclones on people and places within the United States cannot be ignored. We are about to see once again how tropical moisture from an east Pacific system gets pulled northward in to the Desert Southwest and causes all kinds of issues.
In this case, it’s the remnant circulation of once powerful hurricane Odile. So far, we are seeing quite a bit of evidence of damage to parts of the southern Baja peninsula where Odile made landfall as a strong category three hurricane just a couple of nights ago. There are a lot of people who are without fresh water and other basic needs due to the hurricane and its unlikely path right in to Cabo San Lucas. That story will continue to play out over the coming days as rescue and recovery efforts unfold.
Meanwhile, the moisture from what is still tropical storm Odile will continue to move northward towards Arizona and New Mexico. As a result, flash flood watches have been posted for most of Arizona, parts of southeast California and southern Nevada and a good deal of southwest New Mexico. The threat of excessive rainfall across the region is high over the next few days and this could lead to major issues for areas not used to this much rain.
It looks as though the heaviest rain will come tomorrow and in to Thursday when the bulk of the moisture from Odile arrives. The possibility of seeing 3 to 5 inches of rain raises the odds that significant flooding will occur but the exact location of this is impossible to know right now. Being alert for rapidly changing conditions and being ready to move to high ground will be essential to keeping safe. Anyone traveling across the region is advised to keep a close watch on the local weather conditions and do not try to cross any flooded roads, no matter what you’re driving. Swift moving water can overpower your vehicle in a matter of seconds, we saw this during last week’s flash flood along I-15 northeast of Las Vegas. This is a serious flood threat for the region and people need to take it as such.
I am currently in Tuscon working to document and report on the situation over the next few days. My team and I will will make use of some of the same equipment we use in hurricane storm surge with the idea being that we try to capture video of a dangerous flooding situation without having to be there ourselves. There are numerous low spots, washes, dry stream beds, etc that we can place an unmanned camera close enough to capture video of a flash flood. With the amount of heavy rain forecast for the area, I don’t think we will have too much trouble and in fact, will have to make sure we are well away from those areas when the flooding begins.
I will post updates from time to time using Instagram – follow along @hurricanetrack. These posts automatically hit our Twitter feed as well. In addition, I will have longer duration video blogs posted to our app, Hurricane Impact, throughout the next few days. If you know people in the region, let them know that this is a very serious situation. We may think of rain as being a necessary element of survival, especially in the desert, but too much in too short a period of time can bring havoc. I’ll keep you updated from the ground from the Tuscon area up to Phoenix and over towards New Mexico over the next few days.
As for the Atlantic – no worries anytime soon, Edouard will continue to move on out over open water and no other developments are seen within the global models for the time being.
I’ll post more here later tonight from southern Arizona.
