1991-04-26: Andover, Kansas F5 tornado

[Cody Taylor]

This storm is the reason i became interested in meteorology. At the time i lived 3 miles due east of Mcconnell air force base. I was able to view the tornado throughout much of its lifetime. I watched it as it tracked northeast missing my house by about 2 miles. I have about 30 pictures i took from that day, they can be viewed here.http://s924.photobucket.com/albums/ad87/svtc03bra/Andover Tornado/

A couple of things about the Andover tornado, as there's not much written about its impact in between McConnell AFB and Andover. There were a couple of areas impacted - one was the neighborhood known as Greenwich Heights, along Greenwich Road in between Pawnee and Harry streets. Another was a neighborhood known as Springdale, along 143rd street between U.S. 54 (Kellogg) and Harry Street. Some maps I have seen (like the one here: http://www.tornadohistoryproject.com/outbreaks/the-andover-kansas-outbreak-1991) erroneously show a straight line path between the AFB and Andover, so show it crossing 143rd street north of U.S. 54. In fact, it crossed 143rd steet SOUTH of U.S. 54. I know this because I grew up in Springdale and still had friends of family there at the time of the event and some houses were destroyed. I even visited there a few years later and you could clearly see the path because of the stunted trees. Anyway, it went on to completely destroy the church I attended as a kid, St. Vincent de Paul, located right across Andover Road from the Golden Spur mobile home park, which has long since been beautifully rebuilt. As a matter of fact, the town of Andover is now a very attractive, vibrant and fast-growing community.

I remember being fascinated with the footage from McConnell AFB.

Looking back through the data on this event, I discovered that this was the day which started my fascination with weather. I was living in Coffeyville, KS just east of where the Tornado hit in Montgomery County. I can remember the sirens going on and off every few minutes that evening pretty vividly to this day.

I remember this day like it was yesterday. I was a senior in high school, and I had known 3 days out that that particular Friday was going to be huge. A few random memories from that day:

- I set my alarm extra early that morning to watch the PBS aviation weather show, which showed the SPC (back then, NSSFC) convective outlooks. Even though I had never seen a high risk day personally, I really thought that day was going to be one. Sure enough, it was.

- I told my friends in school who knew I was a weather geek that it was going to be a huge day. They were pretty flippant. Monday when I came back to school, they thought I was a god, even though I was just relaying info that I had heard and seen all week.

- I still have cassette tapes of the infamous KFDI mobile units chasing this tornado and calling weatern Butler county a "Purple Hell" during the event.

- I lived in Newton at the time and we had baseball sized hail around 5pm with the tornado sirens blasting (a different tornado than the one that hit Andover).

Overall, this day, along with the Hesston tornado March 13, 1990, were two of the most memorable weather days growing up in Newton, and really contributed to my passion for the field.

I REMEMBER SEEING A FIRE HYDRANT RIPPED FROM THE GROUND ON TWC. HAVE YOU HEARD OF THAT?

To mark the 25th anniversary of this event, the Wichita Eagle has several write-ups from several who were there. IMHO, the most incredible footage of any tornado EVER has to be the Earl "Duke" Evans video taken from a nearby country club just as the tornado approaches and hits Andover at full-on F5 ferocity. The rotation and multiple vortexes in this sequence is still the most violent I have seen even all these years later. Video and interview with Mr: Evans: http://www.kansas.com/news/weather/article73540802.html You may need a membership to view.

Ya, this is my standard for 'violent tornado appearance'. Incredible horizontal and vertical motion. Years ago when I first saw the video, I thought the tape had been sped up.

Today is the 30th Anniversary of the April 26, 1991 tornado outbreak. Red Rock was @Warren Faidley 's first tornado as well as a watershed moment in tornado research; and Andover stood as the most destructive and tragic tornado of the decade until 5/3/99.

I just saw the posting below. The reference was to nuclear-loaded B1B bombers at McConnell AFB a couple of hundred yards north of the tornado. They were there 24/7/365. The base commander was given the opportunity to evacuate them several hours before but he decided it would be "too risky."

If anyone is interested, here is what it was like to work the first tornado of the Doppler era: https://www.kansas.com/news/weather/article250506624.html

Here is more about the technology in April 1991, Today: The 30th Anniversary of the Wichita-Andover Tornado Part II

The storm warning system saved 82% of the potential deaths (per CDC). Horrible day but a proud accomplishment for weather science.

I attended a conference for educators at which the guy who worked at Witchita NWS in 1991 spoke. He talked about "storage for nuclear bombs" if I remember right (it was a long time ago, though). According to him the only time it was rated at F5 was when it hit the trailer park. Maybe one of the flaws in the old system, I don't know.

Hard to forget that day. Scary that it seems like only yesterday. I remember every detail. Time goes flying by when you are doing something you love.

B-1 bombers loaded with nuclear weapons ?

This video ends with the statement;

" . . . mission-essential facilities were spared, as was a flight-line packed with over 80 military aircraft, including a pair of B-1 bombers loaded with nuclear weapons."

Can the nuclear weapon statement be verified? My imagination runs wild with the thought of tornado lofted nuclear weapons being tossed about. I thought tornado forecasting was essentially invented by Air Force meteorologists presumably to deal with a vulnerability such as this.

.

I'm dredging up an ancient thread here I know, but at the time the Air Force's official line was, "We can neither confirm nor deny the presence of nuclear weapons on this facility," Truth is if there were B1's on the alert pad on the North end, they were loaded with nukes.

The weapons Storage Area (WSA) was a bunkered facility on the South end of the base. Of all the places to be during a tornado at McConnell the safest would have been in the WSA with the canned sunshine.

If you look at the tornado's path and a map of the base at the time, it hit McConnell in about the best place it could have. Gone North and it could have torn up the alert facility, including nuke loaded B1's. South it would have gone through the dormitories, which had little or no shelter, just after shift change.
