Lone Grove Tornado: Blog w/Photos





Wednesday, 11 February 2009

The Lone Grove tornado was classified as an EF-4 following a damage survey conducted by a team from the National Weather Service (NWS) office in Norman on Wednesday, February 11. This means that the tornado winds, based on the observed damage, are estimated to have been in the range of 166-200mph.

>>>"EF" refers to the "Enhanced Fujita" scale. It is named after Ted Fujita, a pioneer in tornado research. His original "F" scale was revamped to better account for the damage sustained at different winds speeds by various types of structures.

>>>It is intended to give  a more accurate estimate of winds. Tornado size and wind speeds are related, as large tornadoes tend to have a more intense circulation. However, one cannot say that a tornado is an EF-4 or EF-5 simply because it is large.  There are numerous cases of a tornado a 1/2 mile wide being only an EF-1 or EF-2.

>>>That's why the damage survey is such an important element in determining actual tornado intensity. The Lone Grove tornado falls in the "severe" tornado category as an EF-4.

>>>The February 10th tornado which devastated parts of Lone Grove is the worst to hit Texoma since 1982 in terms of lives lost.

>>>It is also the first major tornado to strike Carter County since the May 7, 1995 event.

That one heavily damaged the Michelin (then Uniroyal) tire plant.

Please check back on this blog as I'll be posting additional information about the Lone Grove tornado as it becomes available in the next few days.

Take Care,

Steve

    The storm chaser on Hwy. 70 that first announced it was on the ground is our hero. I am sorry to hear he was hit from behind by someone else. Hope he is okay and if it weren't for that man, I don't know what we would have done. 3 seconds after he said "OH MY GOD we have a tornado on the ground one mile south of Lone Grove", our power went out. That put the fear of God in our family and we headed for the storm cellar. We saw the tornado from our back porch but could not tell if it was moving toward us or going north. We just grabbed kids and ran for cover. Thank that storm chaser for everyone I know that was watching and listening to your broadcast during American Idol which was pre-empted and I was recording. I watched the whole weather broadcast today in place of American Idol. I still cry when I watch it and thank God we still have our lives. The loses were devastating to say the least.

    Bryan, I was listening to the scanner and heard the EOC Director contidict the person in charge at Lone Grove's Fire Station (I assume the Fire Chief) I heard the Lone Grove person say " I have got guys confirming a tornado on the ground" but the EOC guy kept saying I hear what you are saying but I just don't see a tornado on my radar. Then I heard the person at Lone Grove Fire say " blow em anyway Lone Grove we got a tornado on the ground". I think Bryan an answer to your question is simple---siren=take immediate precautions for safety. Sometimes also I have heard some towns blow the sirens when there is a tornado warning and no actual tornado. Guess what those people after time start thinking " oh heck there is no tornado they are blowing the sirens again". I remember a story about a boy that called wolf. I think that the decision to sound the sirens is a judgement call.

    I'm not blaming anyone. I was well aware of the storm and was watching the situation 45 mins before the storm. my point is what is the purpose of the sirens? we need to have a direct purpose in using them. When the sirens sounds what does it mean? Is a tornado on the ground, has a warning been issued etc. we need to use every available voice to get the warning out as far ahead of time as possible. the point about having the emergency director at county make that decision is that he is looking at radar is in contact with the NWS and listening to reports from in the field. Let him make the call, it's nothing personal against anyone.

    Just for your information (BRYAN) we have two new sirens because of the had work of the fire chief. If not for his efforts we would have the same 3 that don't work. We would have got 3 new ones but the city manager waited to long after we got the money from a grant and the price had risen to where we could only afford 2 new ones. You should not blame others for lack of time. You are responsible for yourself and should have access to tv, internet, scanner, weather radio, or other things to make you safe. The sirens blowing should not be your indication to run or take cover. You should use your own brain and make your own decisions based on what you see and hear. I don't know about you but I could hear it comming for at least 5 minutes before it hit town. So maybe you need to take the i-pod out of your ears and blame yourself for your lack of time to take shelter.

    Does anyone know what the strength was when it hit Majestic Hills, north of Ardmore?

    I agree with the person who suggested cellars at mobile home parks, they are most at risk in severe weather.

    I agree that kxii was in the lead on this storm. My concern is with local storm warning sirens. I live just south of where the storm crossed 70 and we had approx 4 mins of siren warning befoe the storm hit. It seems the sirens should go off when a tornado warning is issued, not when a tornado is on the ground and bearing down on people. When the sirens sound it changes peoples thinking about the situation and the instinct is to move but it is to late in this situation. The sirens should sound giving people as much time to move as possible before the storm is on them. In this situation in LG the sirens should have blown 10-15 mins before they did. Blow the siren and then it's up to the residents to make their own decisions. There should also be a siren sequence for all clear. The county emergency director should control all siren activity and everyone should know the sequence for the warning and then the all clear.

    I think it should be required in all mobile home parks and apartment complexs to have cellars to house their tennants in this kind of event. Bump the rent up $10-$15 per person and it will pay for it's self very quickly and save many lives. Surely after what has happened no one would complain about the increase that may save the life of someone they love or maybe thier own
