Question of the Day - 11 October 2021

Q:

We're considering moving to the Las Vegas area from Oregon. We didn't mind the recent heat wave up here, but the wildfires are just too scary. Of course, everywhere has their disasters, but can you tell us what's the worst natural thing that could happen to us there if we moved.

A:

Generally speaking, the worst natural acute event that happens here is flash flooding. At the same time, the worst natural chronic event is drought. Both involve water, of course, but the former is dangerous in the moment, while the latter threatens the long-term prospects of the city. Drought and the lack of water are an issue for another day. Today, we're considering short-term emergencies. 

Even though the average rainfall in Las Vegas is 4.5 inches, the summer monsoon season can often account for a quarter of that in a single storm. Vegas is at the tail end of weather systems that blow in from the south/Gulf of California and the southeast/Gulf of Mexico. And because of the hard-packed desert soil, plus all the pavement in the city, the ground can’t absorb anywhere near that much heavy rainfall, so streets can get flooded very quickly.

It’s not like the flooding you see where rivers overflow and inundate entire towns and cities (which has happened in Reno over the years), but streets with depressions or troughs can accumulate three feet of runoff in places. The flood-control system throughout the valley has come a long way in the past 25 years, but flash floods can still be very dangerous when they hit.

And not just from the water. Due to how dry it is in southern Nevada the rest of the year, the roads absorb a lot of oil and other fluids. When the monsoon rains arrive, the oils separate out, making the roads extremely slick and causing the driving conditions to be a lot more treacherous than from wet roads alone.

Winds can also get fairly extreme in southern Nevada. Ferocious wind storms can achieve speeds of 80 miles per hour and more (hurricane-force winds start at 74 mph), delaying flights in and out, blowing over tractor-trailers, uprooting trees that block streets and knock down power lines, reducing visibility to nearly zero, causing widespread power outages, and destroying casino signs.

But unlike Phoenix, where intense dust storms known as “haboobs” blanket the city, can be 6,000 feet high and 100 miles long, and blot out the sun, Las Vegas is protected from those by the surrounding mountains. 

Las Vegas also sits atop a number fault lines. Earthquakes, which we've covered in previous QoDs, can and do happen, but they’re mild and infrequent.

It snows in the valley on occasion; when it does, driving is fraught with danger, especially since most people aren't accustomed to it. But the snow doesn’t remain on the ground for long.

Tornadoes are rare, but do occur. The last one was on August 6, 2014; the one before that was on April 21, 2001. But they’re short-lived and register the lowest rating on the Enhanced Fujita scale.

Otherwise, temperatures can be extreme. The record high temperature of 117 degrees has been achieved five times; it’s hit 116 on 19 different days and 115 degrees 41 times.

The record coldest temperature is 8 degrees, registered on January 13, 1963. With the record high of 117, that’s a temperature swing of 109 degrees.

Granted, it's not as bad as Minnesota, for example, where swings of 120 degrees aren't uncommon, or Fairbanks, Alaska, where the record high was 99 degrees (2019) and the record low was -66 (1934). That's a swing of 165 degrees! Still, for Las Vegas, which many visitors tend to think never gets cold, 109 degrees of variance is fairly substantial.

    Movin' to Vegas
    Be forewarned.
    Las Vegas is in as severe a drought as Oregon right now.
    However Las Vegas gets 90% of it's water from Lake Mead.
    In 2015 Las Vegas spent $800 Million to build a three mile tunnel to the bottom of Lake Mead in order to get the very last drop of water from the Lake.
    
    Current Lake Mead water level is 1,067 feet.
    At 895 feet, an additional drop of 172 feet, Boulder Dam can no longer produce electricity.
    
    All of this means that moving to Las Vegas will put you under severe water rationing.
    Possibly a higher electricity bill.
    Add to all of this the QOD response to your question.
    
    If you have been to Vegas prepandemic but not since, Vegas is not the same anymore.
    Closed Casinos, crappy service from understaffed casinos, over charged for everything, higher table limits, NO shows, fine dining and shopping disappearing,all a result of Covid-19.
    
    If thinking about a Las Vegas move is about gambling, there are other Nevada cities to move to plus other States.

    Biggest disaster
    The biggest disaster Nevada has suffered is people moving here from "blue" States that have been destroyed by democrat policies and then continue to vote democrat.

    Pros and cons
    About ten years ago I retired and started working on moving to Nevada. I spent winters in Laughlin and looked at rental properties to test drive the area for a year to see how it felt. I felt the summer heat was a fair exchange for Chicago winters. The apartment manager said her only warning were the scorpions in Nevada. You should search Nevada scorpions on line. I never saw one. But there does seem to be a lot of pest control tucks driving around. Water is definitely an upcoming problem. Floods are temporary but the drought is going to be tough to handle. Maybe Nevada will have to start a state tax to keep water and power going. Rent for a year and see how things work out. Good luck.

    My list
    The Joe Biden administration tops my list of the worst disasters to hit, not only Vegas, but the entire world.

  • jpfromla Oct-11-2021
    Wow
    And I thought it was when ElDiablo took over CET, was the worst disaster.

  • Rick Sanchez Oct-11-2021
    Stop it
    Would you people please stop with the Red and Blue BS. It's getting very tiring.
    When are all of you going to realize that we're all American's and all this in fighting is going to kill this nation.
    You can't tell me China and Russia wouldn't love to see us fail.

    Oregon versus Vegas
    If you want to talk about natural disasters--the exposure to them is much greater in Vegas than in Oregon. Oregon (at least the populated areas in the western part of the state) virtually never suffers a weather-related disaster. There are no significant earthquakes. We don't have severe droughts. Because we have lots of trees and favorable topography, flash floods are rare. It's a pretty safe place. And while wildfires are a concern, they rarely happen in populated areas and their duration and impact is limited.
    
    The weather and the people are both far nicer in Oregon, but that's a different question.

    Worst Disater
    The biggest disaster is resort fees.

    To add re: flooding
    As mentioned Las Vegas only gets 4.5 inches of rain per year. When rainfall is that low a city is NOT going to spend its tax dollars on developing a comprehensive storm drain system. So it takes very little rain for streets to flood.
    
    Comparing Oregon (I live in Bend) to Las Vegas in turns of disasters:
    
    - Earthquakes are worse in Oregon because Oregon is located on the ring of fire. There is a lot of seismic activity.
    - Volcanos are everywhere in Oregon and they aren't all dead.
    - Flooding is probably a push as central Oregon is a desert. We only get about 11" of rain a year but where I live there are no sidewalks, gutters, or storm drains so flooding is a thing.
    - Snow is far worse in Central Oregon.
    - Cold is far worse in central Oregon.
    - Heat is far worse in Las Vegas although Bend did hit 107 this summer.
    - Drought is a thing for both but Las Vegas is worse; all of my water comes from a well on my property. If that dries up there is no municipal water supply I can use.

    "Natural" vs "Man-Made"
    Most of the unpleasant things mentioned in the comments are man-made, not natural events like the QOD person asked about. Man-made events can be as unpredictable as human beings are. But what's easily predictable is the natural event of water shortage. That crisis is a certainity when you keep having large population growth in a desert. Maybe there should be a poll just for Vegas residents, asking them if they feel positive or negative about the future of Las Vegas and what things they regret (if any) about moving here.

    Rain
    the heavy rains cause major accidents on the roads as the accumulated oil/tire marks get slick. little or no drainage causes road flooding and eejit drivers will try to navigate those roads. and SO agree with those who commented on leaving the politics out of the posts!! geez...

  • Doc H Oct-11-2021
    What about the man-made?
    Portland.....need we say more? Watch the goings on in that city, especially during 2020 on various media platforms. Homeless problems. Does the state still have one of the highest suicide rates in the nation? And for a place that appears to sell itself as so woke and liberal, why the lack of diversification that this group often obsesses about? Just did a search on Portland Oregon and comes up big time on searches, labeled the "whitest" big city in American. Now I don't care one bit what color one is, I judge people based on their character, but with many liberals obsessed with diversity and talk about the importance of it, how can they allow and stand this? 
    
    My point? Perhaps some people should stop worrying about what they can't control, ie natural "disasters", weather, and start focusing on what they can control in their own backyard and make their own backyard more pleasant and livable to their liking before considering moving elsewhere. Just a thought.

    An excellant point
    Water concerns.
    The greatest harm to Las Vegas water comes from visitors.
    On weekends and Holidays, millions of visitors invade Las Vegas consuming gallons of water.
    Water that would help Las Vegas locals survive the drought.
    However those same invaders supplement the economy so they are welcomed.
    
    In the past casinos were prohibited from serving water to their customers as a drought measure.
    Soon, that will happen again.
    Of course they could buy water, imported water at that, but not imbibe in Las Vegas water.
    
    However taking showers in hotels, flushing toilets, and drinking sink water was not regulated.
    Protesters would leave the water running in their rooms as they left.
    
    Maybe Clark County lawmakers need to implement restrictive devices on hotel water.
    Or at least meter room water usage and charge guests for excess water use at checkout with that fee going toward buying imported bottle water given freely to locals.

  • Doc H Oct-11-2021
    for the "we are going to run out of water!" people....
    Solution: treated waste water, made drinkable via a process using microfilters, RO, ultraviolet light w hydrogen peroxide. Meets or exceeds all state and Federal drinking water standards. In use in Orange County CA for years now. Water "Problem" solved. Look it up, many articles, videos, etc out there on the topic.

    Moving
    Having more Californians move here.  They’re ruining our state!

    What an incredible group of answers
    The class has really gotten off topic (again). Even the answers about water are equivalent to talking about car registration fees, the price of gas, taxes and the above mentioned electric bills, etc. But I think the gist of the question is more like what unexpected and/or unplanned disastrous things can happen. Fires, earthquakes, floods, and the like, and their probabilities and effects are what the questioner wanted. Although he/she surely is getting a taste of what their new neighbors would be like. Give it to 'em straight. The alien invasion would pick out LV because the brightness makes them think it is the center of power. Or maybe it will be attacked by a sharknado.

    Political Nonsense
    You know people have nothing better to do than to make a simple and valid question into a political statement. No one cares what party you belong to when it comes to rationing water, taking care in extreme heat or avoiding other disasters, we're all humans and taking care for one another shouldn't be so difficult.

    "You know people have nothing better to do than to make a simple and valid question into a political statement."
    
    Where have you been? Water, climate, wildfires, green this and that, and far more, have been turned into front and center political matters by a large part of the population and politicians who link and sell such matters in a bundle and whole heartedly believe they are linked. Some of course link for personal gain but that's another story.  The majority of the masses elect reps that make this matter what it is, front and center. And said masses buy into it. Right or wrong, majority rules, it is what it is, so it's not surprising you see what you see here in responses, right? Welcome to the new reality, surprised you haven't noticed it's all one in the same now. 

  • Dave_Miller_DJTB Oct-11-2021
    My two cents 
    Some of these responses have gotten so far off topic that I felt that I should add my 2¢ as well.
    
    That’s all. I’m done. 🤪
