Since officially kicking off on Sunday, the weather has been less than cooperative for the VORTEX2 tornado field study teams. From their starting point in Oklahoma, there simply has not been severe weather worthy of them chasing. That is changing right at this moment as the team is on the road and headed to western Texas.
VORTEX2 (Verification of Origin of Rotation in Tornadoes EXperiment2) is nothing short of the most ambitious field study of tornadoes ever launched. Comprising a team of more than 80 scientists utilizing 40 vehicles, 10 mobile radar units and an Unmanned Aerial Vehicle (UAV) from the United States, Canada, Australia and Finland, the study hopes to answer many of the questions about twisters that we do not have answers to.
How do tornadoes form? What exactly causes the wind to spin into a concentrated funnel? How can we tell exactly when a tornado will form and when it will die, or how long it will last? Why do some thunderstorms produce tornadoes and others do not? What is the structure of tornadoes? What is the relationship of tornadic winds to damage?
The American Red Cross has updated its tornado safety guidelines, modifying longstanding recommendations putting them in conflict with those provided by NOAA and the National Weather Service. The new guidelines no longer recommend evacuating a car if a tornado is about to strike and finding a low-lying ditch to hide in. Instead, the Red Cross is now recommending remaining in the vehicle.
Until now, all tornado safety guidelines were consistent in saying that remaining in a car during a tornado, just like a mobile home, is one of the worst possible places to be. The vehicle stands a great chance of being picked up and thrown and destroyed with its occupants trapped inside.
The National Weather Service, and the Red Cross until now, believes that lying flat in a ditch provides a greater chance of survival. Your body provides a smaller target for winds and by being in a ditch, debris and winds have a better chance of passing over you.
If you are caught outdoors, seek shelter in a basement, shelter, or sturdy building. If you cannot get to shelter, a recent study* suggests doing the following:
Get into a vehicle, buckle your seat belt, and try to drive at right angles to the storm movement and out of the path.
If strong winds and flying debris occur while you are driving, pull over and park, keeping seat belts on and the engine running. Put your head down below the windows, covering with your hands and a blanket if possible.
Vehicles are extremely dangerous in a tornado. If the tornado is visible, far away, and the traffic is light, you may be able to drive out of its path by moving at right angles to the tornado. Otherwise, park the car as quickly and safely as possible — out of the traffic lanes. [It is safer to get the car out of mud later if necessary than to cause a crash.] Get out and seek shelter in a sturdy building. If in the open country, run to low ground away from any cars (which may roll over on you). Lie flat and face-down, protecting the back of your head with your arms.
Researchers for the Red Cross cited studies from historical tornado damage, injuries and deaths. Rick Bissell of the University of Maryland-Baltimore County was head of the committee that wrote the new recommendations and had posted to his blog, “We found no evidence to support the NWS suggestion that people should lie in a ditch during a tornado if they cannot find solid shelter.”
It should be noted that the “recent study” the commendations cite is actually an older one from 2002. Further, Mr. Bissell’s blog comments have since been removed from the website.
Now Americans are faced with two competing recommendations which could make the difference between life or death. Many believe the Red Cross’ issuing of these new recommendations without collaboration with the weather experts at the National Weather Service is irresponsible. However, there are no hard rules when dealing with Mother Nature and what works in one situation, may not work in a comparable one at a different time.
When driving in open country and you see a tornado, simply drive away from the path of the tornado – usually at a 90 degree angle to the path is best. While we all have seen video of people doing it, do not seek shelter beneath a highway underpass as these act like wind tunnels and actually serve to increase the wind speed and collect flying debris. In the extreme situation that you simply cannot get away from a tornado, abandon your vehicle immediately. Lie down in a ditch or culvert and cover your head. This isn’t a particularly good option, but it is safer than remaining in a vehicle.
If you are caught outside with no place to seek shelter, crawl into a ditch or culvert and cover your head. Getting as low as possible will decrease the odds of you being struck by flying debris. This is not ideal, but it is your best course of action.
Ideally you would of course escape the tornado by outrunning it as outlined above or seek shelter in a sturdy building – knock on doors if you have to.
If you are that close to a tornado, pray! If the option to drive the other way is not available… it is luck of the draw. I used to tell my students to get out and curl down in a low ditch by the road with their heads covered – to protect from flying debris. Honestly, who is going to think of getting outside when it gets worse? The car may provide some protection from flying debris. Which in a tornado, could be another car. I can see the fault in getting out of your car, only to get hit by another. The myth of hiding under a highway overpass has been proven wrong. So, drive away or pray!
As is customary, the governor has declared this week Severe Weather Awareness Week. This is an opportunity for the public to get reacquanted with the dangers severe weather presents in Colorado.
Tornadoes, lightning, hail, severe wind and flooding are very real hazards that Coloradoans face every year during severe weather season. It is important that you know what to do to protect you and your family.
In conjunction with the National Weather Service, Examiner.com will be publishing our Severe Weather 101 series. Each day this week a weather hazard will be discussed in depth and we will outline protective measures you can take to keep yourself and your family safe. Please be sure to check back every day to read these important message.
Thunderstorm hazards around the corner…are you prepared?
Severe thunderstorm season will be soon upon us. Do you know how to stay safe around tornadoes, flash floods, lightning, hail, and damaging winds? This is the week to learn. This week, April 19th to 25th, is Colorado severe weather awareness week. This is the time to learn more about severe weather in Colorado, develop severe weather preparedness plans, and test vital communications.
Can we learn lessons from the past severe weather events? Just last year on may 22nd an EF3 tornado raced north through Weld and Larimer counties resulting in one fatality. Several injuries and destroyed or heavily damaged hundreds of homes. Two years ago, on March 28, 2007 the town of Holly was heavily damaged by another EF3 tornado that resulted in two fatalities. Twelve years ago on July 28, 1997 a devastating flash flood occurred in Fort Collins resulting in 5 fatalities and millions of dollars in damage.
Each year for the past 20 years there have been an average of 50 tornadoes in Colorado, 3 people killed by lightning and another 15 injured by lightning.
The National Weather Service offices which cover Colorado will issue a series of public information statements during the week covering the following topics:
Monday…Watches and warnings
Tuesday… Tornadoes and tornado safety
Wednesday…Flash floods and flash flood safety
Thursday…Downburst wind and hail
Friday…Lightning and lightning safety
Saturday…A review of the week
A time to test your warning reception and communications systems is planned. Each national weather service office serving Colorado will send test tornado warnings on Tuesday April 21 between the hours of 8 am MDT and 11 am MDT. These test warnings will be sent to the emergency alert system, the internet, NOAA weather radio and law enforcement communications systems.
Safety information, watches, warnings, forecasts, past weather and much more information is available at your local National Weather Service web sites:
The single largest and most ambitious field study to increase our understanding of tornadoes is set to kick off next month. The Verification of Origin of Rotation in Tornadoes EXperiment2 (VORTEX2 or V2) will feature more than 50 scientists utilizing 40 vehicles, 10 mobile radar units and an Unmanned Aerial Vehicle (UAV).
The study which will run from May 10 to June 13 will become the largest mobile in-field laboratory ever assembled to study tornadoes. In a statement Louis Wicker, research meteorologist with NOAA’s National Severe Storms Laboratory and V2 co-principal investigator said, “Data collected from V2 will help researchers understand how tornadoes form and how the large-scale environment of thunderstorms is related to tornado formation.”
Operations will be controlled at the National Weather Center in Norman, Oklahoma while the mobile units chase tornadoes across Tornado Alley and the central Great Plains. The target area for the study ranges from southern South Dakota through Nebraska, Kansas, Oklahoma and the Texas Panhandle. Eastern Colorado, home of many tornadoes, is included in the study.
This unprecedented gathering of scientists and technology hold incredible promise for the research that will be gathered. The original VORTEX program which happened from 1994 to 1995 documented the entire life cycle of a tornado from start to finish, the first time that had ever been done. That research greatly enhanced our understanding of twisters and led to much improved tornado warnings that help to save lives today.
VORTEX2 seeks to build on that research and the research that has taken place since. According to the project website it will seek to answer such important questions as: How do tornadoes form? What exactly causes the wind to spin into a concentrated funnel? How can we tell exactly when a tornado will form and when it will die, or how long it will last? Why do some thunderstorms produce tornadoes and others do not? What is the structure of tornadoes? What is the relationship of tornadic winds to damage?
An important finding from the original VORTEX experiment was that the factors responsible for causing tornadoes happen on smaller time and space scales than scientists had thought. New advances will allow for a more detailed sampling of a storm’s wind, temperature and moisture environment and lead to a better understanding of why tornadoes form – and how they can be more accurately predicted.
– Stephan Nelson, NSF program director for physical and dynamic meteorology.
VORTEX2 features scientists and students from the United States, Canada and Australia in collaboration with government agencies, private industry and educational institutions. Many luminaries within the storm chasing and severe weather research community will participate including Dr. Josh Wurman of the Discovery Channel’s Storm Chasers TV show. Some of the notable participating organizations include Center for Severe Weather Research, Rasmussen Systems, NOAA National Severe Storms Laboratory, OU/NOAA Cooperative Institute for Mesoscale Meteorological Studies, NSF-sponsored National Centers for Atmospheric Research, Penn State University, University of Oklahoma, Texas Tech University, Lyndon State College, University of Colorado, Purdue University, North Carolina State University, University of Illinois, University of Massachusetts, University of Nebraska, Environment Canada, and the Australian Bureau of Meteorology.
The end of the week saw severe weather claim the lives of seven people across the nation on Thursday and Friday.
Mena, Arkansas Tornado Claims Three Lives
Daylight Friday in the western Arkansas town of Mena brought a devastating sight after a tornado tore through the town killing three people and injuring at least 24. Reports are that hundreds of homes and businesses have been destroyed in the town of 5,000.
Tornado sirens blared yesterday evening in the town warning of the coming danger. At about 8:30pm local time the twister struck. Two women and one man lost their lives in the storm. One victim died in a collapsed house, another in a front yard and the third in a Masonic Lodge.
Wildfires in Texas and Oklahoma Wildfires Claim Two Lives, Injure Dozens
Wind-driven wildfires in Texas And Oklahoma proved deadly Thursday afternoon as a Texas couple was killed in the blazes and dozens more injured. The fires in western and central Oklahoma injured at least 34 people and burned over 100 homes. In Texas, a former television reporter and his wife were killed.
High winds, low humidity and an abundance of dry fuels sparked the wildfires and made for prime conditions for them to quickly burn out of control. In Oklahoma the fires started along I-35 and forced its closure for a time although it is now open. Entire towns were evacuated including Healdton, Sparks, Velma, Wellston and Midwest City.
Mother and child killed by tornado in Murfreesboro, Tennessee
A mother and her three month old baby were killed in Murfreesboro, Tennessee today when a tornado went through the central part of the state Friday. The Tennessee Emergency Management Agency reports that 30 were also injured by the twister as a line of storms stretching from Alabama, across Tennessee and into Kentucky wreaked havoc. The deadly twister comes on the heels of one that killed three people in Arkansas Thursday.
The mother and child whose lives were lost were taken to Middle Tennessee Medical center but were dead when they arrived. The city of 105,000 saw roofs ripped from homes and trees downed as the twister struck the northern and western parts of the city.
Researchers at Florida State University announced that global hurricane activity continues to decrease and is now at levels not seen since 1977. The researchers say that, “Tropical cyclone (TC) activity worldwide has completely and utterly collapsed during the past 2 to 3 years.”
Using a measurement called the Accumulated Cyclone Energy index (ACE), researchers see a tremendous drop in cyclone energy for the globe as a whole. While the north Atlantic saw above normal levels of ACE in 2008, it represents a relatively small amount of the global hurricane energy and as such cannot compensate for the much reduced levels elsewhere on Earth.
Just as there are active periods of hurricane activity around the globe, there are inactive periods, and we are currently experiencing one of the most impressive inactive periods, now for almost 3 years.

We have written before about the great opportunity the National Weather Service provides by giving storm spotter training during the start of the severe weather season. That time is now here and training sessions start in the coming week and new sessions have been added since we last reported on the topic.
The storm spotter program is a nationwide program with more than 280,000 trained spotters. These volunteers report weather hazards to their local National Weather Service office providing vital information when severe strikes. Data from spotters include severe wind, rain, snow measurements, thunderstorms and hail and of course tornadoes.
Storm spotters are part of the ranks of citizens who form the Nation’s first line of defense against severe weather. There can be no finer reward than to know that their efforts have given communities the precious gift of time–seconds and minutes that can help save lives.
By completing one of these training classes you can become an official storm spotter. When severe weather strikes, you can report it by calling a special toll free number or submit your report via the National Weather Service’s website.
These are great sessions for anyone wanting to learn more about the severe weather we experience in Colorado, whether you want to be an official spotter or not. All training is free. Topics include:
This Sunday, February 22nd at 6:00pm MST, the Weather Channel will premiere the new season of its series Storm Stories. Most notably, the first episode will highlight a weather event from last year that struck very close to home – the May 22nd Windsor Tornado.
For those that haven’t seen Storm Stories, it is an exciting, sometimes scary and sad series discussing significant weather events as seen through the eyes of those that experienced it firsthand. For the Sunday episode, renowned storm tracker Jim Cantore from the Weather Channel will tell the story of the twister using footage from a variety of sources, including the video most have seen from KUSA (see below).
The kickoff of the new season of Storm Stories is actually the beginning as well of the Weather Channel’s ‘Tornado Week’ in which twisters are front and center. Other episodes of note during the week:
Monday – the “Parkersburg, IA, Tornado” on May 25, 2008, killed seven people and demolished the southern half of the town; first-hand accounts are given by residents.
Tuesday – the “Greensburg, KS, Tornado” on May 5, 2008, wiped out the entire town. The story is told through the experiences of next-door neighbors who saved a mother and her baby from the rubble.
Wednesday – “Super Tuesday” tornadoes cut a swath over a wide area Feb. 5, 2008; touching stories come from people that were affected in Arkansas, Kentucky and Tennessee.
Thursday – the “Boy Scouts Tornado” hit the Little Sioux Scout Ranch in western Iowa last June, catching everyone off guard. The surviving scouts are forced to put their training to use in the midst of a terrifying situation to help keep injured scouts alive in the aftermath.
The 11th annual National Storm Chaser Convention hits town this weekend as some of the nation’s premier storm chasers converge on Denver. Whether you are a seasoned chaser or just someone with an interest in the weather, this is an extraordinary opportunity to mingle with and hear from some of the biggest names in severe weather. The event is organized every year by two of the biggest names in storm chasing – Roger Hill and Tim Samaras.
Held at the Red Lion Inn in Parker, the event kicks off Friday night with an ice-breaker and a chance to mingle with other weather enthusiasts. Saturday morning the event starts in earnest with an extraordinary slate of speakers covering an array of topics. Saturday night is the infamous video night where videos and photos from last year’s record setting year of tornadoes are sure to play a big part and Sunday the convention continues with additional speakers.
The biggest sporting event of the year is of course the Super Bowl and no doubt this year’s matchup between the Pittsburgh Steelers and the Arizona Cardinals is sure to be no different. Super Bowl XLIII will be held in Tampa Bay, Florida and the weather forecast is looking to be just about perfect – see our game day forecast below.
What about Super Bowl’s in the past? Was there ever any notable weather during the big game? You bet there was. Here are some fun facts (courtesy wx-man.com):
17 of 42 Super Bowls played indoors
16 of 42 Super Bowls had a trace or more of rain nearby
2 Super Bowls had snow on game day (1982,2006)
1 Super Bowl played during an ice storm (2000)
Warmest high temperature of 82° (1973,2003)
Coldest high temp for dome game 16° (1982)
Coldest high temp for non-dome game 49° (1985)
Wettest Super Bowl .92 inches (2007)
Outside games with high wind gust (1980, 1984, 1989,2007)
You will notice there isn’t really any mention of severe weather in those statistics. The NFL has been pretty fortunate on that front with nothing particularly notable – rain always seems to be the biggest threat.
