One Year Later -- Remembering the Joplin Tornado

May 22, 2012

One year ago, on May 22, 2011, nearly one-third of the city of Joplin, Mo., was lost to an EF-5 tornado.

The tornado seemingly came from nowhere; at least is seemed that way to many in Joplin. There was no tell-tale funnel churning on the western horizon. There were no tornado sirens – at least not this time – and the only tornado warning the public received seemed to indicate the tornado would pass to the north of the city. All those in Joplin saw was a massive black wall descending on the western side of the city. Within that wall was one of the most destructive and deadly tornadoes in this nation’s history.

The particular storm that spawned the Joplin super-tornado was one of many tornado producing cells that day across the Midwest. At 5:32 PM, CDT, the tornado initially touched down on the southwestern edge of the city limits. Damage was sporadic and minor only a few trees were uprooted. But the tornado soon swelled into a monster, the evolution of which was captured by a pair of storm chasers who happened to be in the right place at the right time (video link).   Another pair of chasers recorded their trip into Joplin following the tornado.  They plea with officers to start the sirens which still had not sounded and try reporting it by phone (video link).
 
The storm churned east-northeast, growing in intensity as it moved into more densely populated neighborhoods. It seemed to feed off the structures it was destroying. By 5:41 PM, the storm was well within the city. The storm swelled to nearly a mile in width, packing winds in excess of 200MPH. Some estimates suggest the storm winds topped 250 MPH at its peak.
 
Video evidence from the day suggests many were unaware of what was happening to their city – or what was about to happen to them. One such video shows a van full of storm chasers frantically trying to drive south through the city. The storm is clearly visible on their right and ground-level purple, blue and green flashes suggest power lines are being ripped down. In the background we see people casually going about their business during the dinner hour. Some are trying to get home to their families others are seen pulling into a fast food restaurant drive through. It’s heart wrenching because I’m certain that some of those in the video either perished or were injured.
 
By the time the tornado left the city some estimates say as much as one-third of the city was left in ruins. Approximately 8,000 structures were destroyed including: one of the city’s hospitals, a nursing home, 10 public school buildings, and the commercial center of the city. Major box stores such as Home Depot and Wal-Mart were leveled with customers inside. Some who would not survive. 
 
In total, 161 people were killed, making it the deadliest tornado in 60 years. To date, damage estimates stands around $2.8 million; although some expect that number could climb to and exceed $3.0 million. At $2.8 million, it is the costliest tornado since at least 1950.
 
Despite the carnage and tragedy that the storm left behind there are also stories of hope coming from Joplin. In addition to federal and state disaster aid, donors from across the country and around the world have stepped up for Joplin.
 
Agweb.com’s own Margy Fischer reported that manufacturers Vermeer Corp and Kubota Tractor Corp pitched in to help with stump removal and tree planting. Donations from the United Arab Emirates helped purchase new laptops for school students to replace lost text books. In addition, the United Arab Emirates recently donated $5 million to Mercy Hospital (formerly St. John’s which was destroyed in the storm) to develop a new pediatrics wing and neonatal intensive care unit (NICU).
 
The school district reopened in temporary buildings and Wal-Mart and Home Depot have both returned too. But what has remained through all the blood, sweat and tears is the determination of those who live in Joplin. Their hard work and dedication combined with help from the outside – both financial and physical – have ensured that this city will survive and will be rebuilt better than ever. That is a true testament to the human spirit.
 
(Authors note:  Videos used and mentioned in this article have been attached as link only, not embedded.  I did this so those who lived through that day would not have to relive the nightmare over again.  If you choose to watch the videos, that is up to you.  I'll warn you, there are graphic scenes and language in each one.)

Automated Weather Alerts Roll Out to Cell Phones

May 16, 2012

Starting this month, a new type of text message may be delivered to your phone and it’s not one you want to ignore.

The Wireless Emergency Alerts (WEA) service is free and will be rolled out to more than 97% of wireless users this month.
 
Beginning this month, most cell phone users will begin receiving special text messages warning them of life threatening weather conditions, Amber Alerts, and Presidential Alerts for national emergencies. 
 
Alerts will be issued for life-threatening events such as tornadoes, hurricanes, flash floods, tsunamis, dust storms, high winds, blizzards, and ice storms.
 
The best thing about this service is the text messages are location based – not based on your billing address – so if you’re travelling and a weather threat is imminent, you’ll still receive the warning based on the location of your phone.
 
According to a report from USA Today, a National Weather Service spokesperson described the reports as “very brief, under 90 characters.”   The alerts are “intended to prompt people to immediately seek additional information through the wide range of weather alert communications available to them,” the spokesperson added, “such as the Internet, television, radio, or NOAA Weather Radio.”
 
The alerts will be used specifically for weather warnings, where threatening weather is occurring or imminent. Alerts will not be issued under the WEA service for watches or advisories.
 
WEA can also be used for urgent alerts such as Amber Alerts and Presidential Alerts for national emergencies. 
 
According to USA Today, Amy Storey, spokeswoman for CTIA – The Wireless Associataion, said wireless carriers participating in the program include: AT&T, Cellcom, Cricket, Sprint-NEXTEL, T-Mobile, US Cellular, and Verizon Wireless.
 
According to the CTIA, the WEA service uses a different technology that is not subject to congestion or wireless network delays. Messages are distributed to a targeted, geographic area, which are then transmitted using cellular towers within the targeted area.

Under previously available commercial applications, cell phone users could subscribe to alert notifications; however, they were often subject to pre-determined locations or a billing address.
 
Under the WEA service, a cell phone user from Pennsylvania could receive a tornado warning for Kansas if he or she were in the targeted area.
 
The WEA service is the first national service by the federal government and the wireless industry. The collaboration includes the Federal Communications Commission (FCC), Federal Emergency Management Agency (FEMA), Department of Homeland Security (DHS), National Weather Service (NWS), and other agencies.

Damaging Storms Possible across Midwest; Record-Breaking Heat in the South

May 02, 2012

Damaging severe thunderstorms are expected to strike portions of the Midwest today, with residents in Nebraska and Iowa facing the greatest risk.

This morning’s severe weather outlook by the Storm Prediction Center included a moderate risk for severe thunderstorms from central Nebraska to central Iowa including the cities of Omaha and Des Moines.

The storm system, which brought severe weather to the Midwest Tuesday night into the early hours on Wednesday, is expected to gain strength today as it interacts with warm, moist air surging in from the south.
 
While a widespread severe weather outbreak is not expected, any storms that develop have the risk of damaging winds over 60 MPH, hail in excess of 2 inches in diameter, localized flash flooding, and isolated tornadoes.

Elsewhere, severe thunderstorms are expected to extend in an arch from the Midwest to the Great Lakes and south to the Mid-Atlantic States of Virginia and North Carolina.
 
Storms that do develop from the Great Lakes to the Mid-Atlantic will form ahead of a warm front. While some storms will exhibit severe characteristics, the main threat from these storms will be torrential downpours and gusty winds.
 
Behind the warm front, unseasonable heat will build in across the southeast as much of the region will see July-like temperatures begin today and last through the end of the week. Temperatures are expected to reach near 90 for some locations through the end of the week. Residents across the southeast can expect this to be a record-tying, if not record-breaking, heat wave.
 
southeast dm
US Drought Monitor graphic shows extreme to exceptional drought conditions across the southeast.  Unfortunately, this week's heat wave will do little to relieve the drought situation. 
 
Unfortunately for agricultural interests in the southeast, the heat wave also means little chance for widespread beneficial rain over the next few days. 
 
A dominant area of high pressure off the southeast coast will form a blocking pattern keeping rain away from the areas that need it most in the southeast. According to the US Drought Monitor, much of the southeast is experiencing extreme to exceptional drought conditions with the worst areas in Georgia, Florida, South Carolina, and Alabama.

Preparedness Is Key to Surviving a Severe Weather Event

Apr 27, 2012

One year ago this week, from April 22nd to 28th, one of the largest tornado outbreaks occurred in the United States, spawning more than 300 twisters and killing hundreds.

Dramatic video of last year's violent tornado which struck the heavily populated area of Tuscaloosa, AL. 

 

This year, to mark the one-year anniversary of that deadly week, the National Oceanic and Atmospheric Administration (NOAA) partnered with the Federal Emergency Management Agency (FEMA) to raise awareness and, hopefully, save lives through the first-ever National Severe Weather Awareness Week.
 
The week-long event focuses on what individuals, families, and businesses can do to prepare themselves for severe weather. According to NOAA and FEMA, preparedness can be accomplished by knowing your risks, having a plan, building a kit and staying informed via NOAA Weather Radio. Being prepared for a severe weather event will help you know what to do before, during and after extreme weather. In addition, in the age or mobile technology and social media, severe weather preparedness also means staying connected with friends, family, and neighbors and encouraging them to active proactively toward severe weather threats.
 
Know Your Risk
 
Extreme weather, from tornadoes to ice storms can impact any part of the population at any time.    The first step to severe weather preparedness is to know your risk for severe weather. Check the weather forecasts regularly and sign up for alerts from your local emergency management officials and media. When considering your shelter options, consider the type of extreme weather which may impact you.
 
Have a plan
 
Municipal governments and businesses such as schools, hospitals, nursing homes, and day cares all are encouraged to have an emergency plan in place, but what about you and your family? Each household should have an emergency plan that identifies potential hazards, including man-made and natural disasters. Once hazards are identified, design your plan around them. Review your plan often and practice it. Think like an emergency or risk manager. How will you, your family, or your business react when a disaster occurs? Will they know what to do at a moment’s notice?
 
Once you’ve responded developed a plan, share it.     Collaborate with your friends and co-workers. Your actions may inspire them or you may be able to exchange information.
 
Build a Kit
 
You’ve developed an emergency action plan, but do you have the supplies on-hand ready to go in an emergency? Many emergency and risk managers recommend you have a kit or go-bag ready to take with you at a moment’s notice. 
 
Assembling a kit is easy. All you need are a collection of basic items your household may need in the event of an emergency. You should plan on having enough food, water, and other essential supplies to last 72 hours in case you cannot be reached immediately.   Also remember that basic utilities such as phone, electricity, gas, water, and sewer may be cut. Your kit should include provisions to deal with a loss of such services. Also, be sure to account for prescription medications, this can be an easily over-looked necessity for many. For additional resources on how to assemble an emergency kit, check out this guide from Ready.gov.
 
Be Informed
 
When threatening weather strikes, you need to be sure you are informed of the latest watches and warnings. The best way to ensure you are receiving the information in a timely manner is to purchase a NOAA weather radio. 
 
Weather radios are relatively inexpensive and some even offer features specifically for those who are hearing impaired. Weather radios with SAME alerting offer the ability to only program alerts for your county or parish. However, I recommend programming neighboring counties in to your weather radio as well. That way you could potentially know what is coming your way.
 
Mobile devices such as smart phones and tablets can also receive emergency alerts. There are a number of vendors who provide this service free of charge. However, keep in mind your ability to receive theses alerts in a timely manner is dependent on your signal strength. In addition, constantly checking your phone for weather updates will drain your battery, which you may need to rely on if there is no power to charge your phone.
 
Be an Example
 
I’ll echo the goals of NOAA and FEMA for this week’s awareness event. After you have taken steps to prepare for adverse and threatening weather, be an example to others. Share your knowledge; challenge your friends and family members to do the same. Check with neighbors, members of your church, or at-risk members of the community, such as the elderly and ask them what they would do in the event of an emergency. You can help them by guiding them through making a plan and a kit or even something as simple as helping program their NOAA weather radio
 
The theme of this year's National Severe Weather Awareness Week challenges everyone to be a Force of Nature by taking proactive preparedness measures and inspiring others to do the same.
 
If you have neighbors in your community who can get to your home quickly and safely before an adverse weather event, offer them a place to shelter with you.
 
According to NOAA and FEMA, research shows people are more likely to take preparedness steps if they observe the preparations taken by others. Social media sites such as Facebook, Twitter, and Pinterest are great ways of showing and sharing your preparedness actions with others.
 
Just think, if your preparedness inspires three people to do the same, and those three people each inspire three more people and so on, we could be a Weather Ready Nation in no time!

'Life-Threatening' Weather Possible across Central U.S. Saturday

Apr 13, 2012

A potentially dangerous weather event is gaining strength and is poised to bring severe thunderstorms, damaging hail, and deadly tornadoes to parts of the Central US on Saturday.

The storm will be preceded by a weaker, but still dangerous round of severe weather today across the Central and Southern Plains, bringing with it the threat for flash flooding, dangerous lightning, hail and wind damage, and possibly a few tornadoes.
 
Unfortunately, today’s weather is only the precursor for what appears to be a historic severe weather outbreak on Saturday.
 
In preparation for Saturday’s severe weather, the Storm Prediction Center (SPC) issued a severe weather outlook for Saturday that includes a "High Risk" for severe weather and high likelihood of a tornado outbreak across parts of the Central and Southern Plains.

According to the SPC, an impressive upper-level low will move out across the Southern Rockies during the day on Saturday while a powerful jet stream surges northeastward into the High Risk area of the Central and Southern Plains. At the same time, ahead of the system, an area of strong to moderate instability will form across Northwestern Texas, Central Oklahoma, and East-Central Kansas. 
 
This instability, combined with strong low-level shearing will create an environment that is very favorable for the development of severe thunderstorms. The SPC added "a tornado outbreak will be likely across the Southern and Central Plains from late Saturday afternoon lasting through the evening and into the overnight period."  Tornadoes that occur after dark as more dangerous as they are difficult to see and warnings may not be heard by people who are sleeping.
 
In the outlook for Saturday, the SPC warned that factors appear to be moving into place to create an environment very favorable for the development of supercell thunderstorms and tornadoes. The SPC also cautioned that the environment would be ripe for large hail with hail greater than 2 inches possible in the most intense storms. Due to the nature of the storms, wind damage is also a possibility. The SPC cited an increasing jet stream, dew points in the 60s, and other factors combining together to make "a tornado outbreak appear likely."
 
The SPC collaborated with National Weather Service (NWS) forecast offices in Wichita, KS; Norman, OK; Topeka, KS; Tulsa, OK; and Dodge City, KS and issued the "High Risk" outlook for Saturday, citing "a potential for a high-end life threatening event across the Southern and Central Plains."

As of Friday morning, other areas at risk for severe weather during the day on Saturday include parts of Texas, Missouri, Nebraska, Iowa, Illinois, Minnesota, and South Dakota. According to the SPC forecast, the greatest risk for significant tornadoes will be from Salina, KS south to Oklahoma City, OK – along the I-35/I-135 corridor (see severe weather probability map).  If you live in the Central or Southern Plains, monitor local media and the SPC for the latest forecast as the areas affected or severity of the outbreak can change rapidly.
 
This is a unique situation where the factors for significant severe weather are almost a certainty more than 24 hours ahead of the event. This should give the public plenty of time to prepare themselves, their families, and their businesses for the likelihood of damaging severe weather.
 
This is a potentially life-threatening situation. Please take the appropriate precautions to protect yourselves and your families, businesses, and property.
