The National Weather Service just released the preliminary 2013 statistics for weather related fatalities.  As you can see in the graph, it compares 2013 fatalities to the 10 year and 30 year annual average.  It breaks it down by 9 different weather hazards.  

The U.S. Natural Hazard Statistics provide statistical information on fatalities, injuries and damages caused by weather related hazards. These statistics are compiled by the Office of Services and the National Climatic Data Center from information contained in Storm Data, a report comprising data from NWS forecast offices in the 50 states, Puerto Rico, Guam and the Virgin Islands.

This is a great reminder to stay aware & cool during the heat of the summer and to check on your neighbors.

To keep your family safe from tornadoes, now is the time to get your shelter.  Our Summer Savings Sale is through July 31.  You have one more week to get the best price of the year.  Check out our different sizes and Summer Savings Sale on our website here

While Tornado Season for Oklahoma is typically March through late August, once we get past May the possibility of tornadoes seem to wane in our minds.  Just this year alone, there were 109 tornadoes in June in the United States, according to the National Weather Service, and five of them were rated EF4.  So far, there have been 17 tornadoes in July.  Three of the June tornadoes were in the Oklahoma panhandle.  As most of us know, tornadoes can form and cause damage any day of the year and any time of the day.

If you do not yet have a storm shelter to protect your family from a tornado, just because May has passed, does not mean you can “wait until next year.”  Now is the time to get the protection your family needs and take advantage of our SUMMER SAVINGS SALE, which is only through the end of the month.

Right now we are scheduling installations of our underground storm shelters about 3 weeks out.  Check out our different sizes and Summer Savings Sale on our website here

Inside or outside.  It’s a hot topic, when deciding on a storm shelter for your family.  Many have strong opinions for both. Here is a list of factors and concerns to consider for each type of tornado shelter.

Inside the Garage

·Concern: “What if we get trapped by debris on the door?”  All storm shelters should be registered with your county.  If a tornado hits your area, the officials will know exactly where to find you.  Even when the EF5 tornado hit Moore, OK in 2013, everyone was helped out (whether from inside a shelter or trapped in debris) within 12-15 hours.         

**A large tree, vehicle or other debris could just as easily block the door of an outside shelter.**

·You don’t have to go outside.  Usually, when you have to take cover in your storm shelter, it is already raining and probably hailing. 

·No eye-sore.  Our storm shelters are underground, with a flush lid design.  Most garages allow for most vehicles to be parked over the shelter and still have access to get inside.

Here in “Tornado Alley” we are all somewhat familiar with tornadoes.  They are fascinating.  Many like to chase them.  And they are each unique.    When it comes to measuring their size and strength, we rely on the Enhanced Fujita (EF) Scale that has ratings from EF0 to EF5.  But which ones hold the records?  Which ones have been the biggest, strongest, and deadliest?  For your inquisitive minds, here are the numbers.

                Highest winds recorded in a tornado: 318 MPH, May 3, 1999, Moore, OK

                Widest tornado on record: 2.6 miles, May 31, 2013, El Reno, OK

                Longest path length recorded: 219 miles, March 18, 1925, the “Tri-State” tornado that traveled through Missouri, Illinois, & Indiana               

                Deadliest tornado: 695 deaths, March 18, 1925, the “Tri-State” tornado

                Deadliest of the modern era (since 1950): 158 fatalities, May 22, 2011, Joplin, MO

                Largest “Tornado Outbreak”: 175...

As we all know, today is the one year anniversary of the horrible EF5 tornado that tore through the community of Moore, OK.  A year later, our hearts still ache for those who lost their loved ones.  Twenty-four people died that day from this terrible event.  And the day before an EF4 tornado killed two people in Shawnee, OK. 

A year later, you can see the people still rebuilding their homes, their businesses, and their lives.  The town is still in recovery mode.  New schools are replacing the two the tornado demolished and are projected to be finished by August.  Many are pushing legislators to have storm shelters added to all new and existing schools.

Here at Thunderground Storm Shelters, we have been honored to be a small part of helping families who were affected by the tornadoes.  We have installed a shelter into the homes of dozens of families that had received damage from the May 20, 2013 tornado. 

Tornado shelters saved the lives of many those two days.

No one can predict the...

While cars can be used to get out of the path of a tornado, they are not necessarily safe havens within one.  The more violent the tornado, the worse damage it can do to automobiles.  The most intense tornadoes can fling vehicles for hundreds of yards and, as in this example, mangle them into nearly unrecognizable heaps and wrap them around trees.  If this car in the picture had contained a driver or passengers, they likely would have perished. 

The NWS recommends that if you are being overtaken in your car by a tornado, then you should get out of the car and into a nearby building or ditch. The new American Red Cross recommendation is that if no building is available, stay in the car - get out of the car and into a ditch only as a last resort. Crouch down with your seat belt on and your head below the windshield level.

It is best to find safer shelter in a permanent building first, or if the tornado is visible and far away, drive at right angles and out of the way of the tornado.  Overpasses offer no extra protection and have proved to be deadly in tornadoes.

Living in Oklahoma, most are familiar with the Fujita & Enhanced Fujita damage scales for rating tornadoes.  The strongest tornadoes with the most intense damage receive the top rating, an F5, or now an EF5.  This is the size that struck our state last May and claimed so many lives.  This is the power that we are all intrigued by and/or fearful of. 

This is the very reason every family needs an underground storm shelter.

We are thankful the first Oklahoma tornado (Stephens County) of the this season was much smaller and no one died.

This is a map of tornadoes since 1950 which the National Weather Service has rated F5 (before 2007) or EF5 (equivalent, 2007 onward.)  The tornadoes are numbered in the order they happened since 1950; so the numbers run from the bottom up. NOTE: Since the (E)F-scale is a subjective damage assessment tool, official NWS ratings may differ on occasion from those of other tornado databases.

April Showers bring May flowers…and can produce tornadoes!  If you have been waiting for the Spring “tornado season” to begin to get your storm shelter, now is the time.  With tornado warnings across much of OK already one day this month, the season has begun.

Need another reason to order your storm shelter?  Here you go – we are offering $150 off your deposit, when you get a free no-obligation quote by May 1st.   You have less than 4 weeks to call and take advantage of our Spring Special.  As always, the deposits ARE refundable, and we usually require a $300 deposit.  OF COURSE, the deposit applies to the price of your shelter, so it is equivilant to getting $150 off of the cost of the shelter.

Once you have made your $150 deposit, you will have until your shelter is installed to pay the balance.  That means more time to save up or get a low interest loan.
