Odile leaves trail of destruction along Baja, heavy rain poised to inundate parts of Southwest

Tropical storm Odile continues to churn away over the Baja peninsula and the Gulf of California

Tropical storm Odile continues to churn away over the Baja peninsula and the Gulf of California

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.

Edouard on its way to becoming a major hurricane but the major news story is Odile

Hurricane Edouard is the strongest hurricane in the Atlantic Basin in over two years. We have to go back to Sandy in late October of 2012 to find a stronger hurricane than Edouard – that’s how slack the Atlantic has been as of late. Never the less, the NHC is forecasting Edouard to become a major hurricane with winds peaking at 120 mph. I suspect it will be stronger given the nature of intensity forecasting. This will help to boost the ACE score for the Atlantic which is now in the mid-20s and climbing. The only issue from Edouard will be swells that eventually reach Bermuda and parts of the East Coast and of course shipping interests in the open Atlantic.

The remainder of the Atlantic, Caribbean and Gulf are free of any areas of concern for the time being.

In the east Pacific, the mega-season continues. Hurricane Odile made landfall last night near Cabo San Lucas as a strong category three causing significant damage to the region. It will be some time before we get a full picture of what happened but rest assured, the region took a hit last night and it’s still going on as Odile tracks up the spine of the Baja peninsula today.

The NHC forecast track keeps the hurricane over the peninsula and then turns it northeast across the northern portion of the Gulf of California. With most of the circulation of Odile over water, it may not weaken as much thus the risk of hurricane conditions spreading northward over the next day or so is high.

As Odile makes its way northward, deep tropical moisture will spread in to parts of the southwest United States. This will lead to an increase in rain chances as the week progresses and may result in significant rain fall for some locations. It is impossible to know which areas will receive the most rain but it is not out of the realm of possibility that we could see 3 to 5 inches. Flooding will once again be a big concern, especially in Arizona and New Mexico where it looks like a bulk of the moisture is headed. It is important for people in the region to pay close attention to NWS watch, warning and other info this week. Tropical cyclone impacts to the Southwest are rare but when they do happen, the results are often dramatic and dangerous.

I am going to be traveling out to Arizona later today – arriving in Phoenix this evening. I will have a full crew to work with utilizing two vehicles and plenty of equipment to document this potentially extraordinary event as it unfolds.

Our goal is to capture a flash flood as it happens using some of the same unmanned camera systems that we use in deadly hurricane storm surge. We can also provide on-site reports to our followers via Twitter, Instagram and of course, our app, Hurricane Impact. In addition, I will be providing The Weather Channel with several reports and live video throughout the field work over the coming days. We will go where the weather takes us, it’s not like a hurricane landfall where we need to be where the eye crosses the coast. The Desert Southwest is vast and often harsh, I have last week as somewhat of a guide to know what to expect but each trip is different and Odile is likely to bring an entirely new set of problems to the region. I cannot stress enough how important it will be for people in the area to keep up to date on the ever-changing situation.

I will post another update here late tonight, probably past Midnight ET and then more tomorrow morning.
