Erick/Mangum, OK Tornadoes, 31 May 1999

  1. Double-Tailed Wall Cloud---Initially the storm had virtually a flat rain free base, but not long afterward, this massive wall cloud formed. The Weather Service confirmed a touchdown out of this feature, there may have been a weak multi-vortex tornado beneath it.
  2. Wall Cloud---Same wall cloud a few minutes later. The base of it has lifted somewhat, but it remains intense.
  3. Needle Tornado---Formed from a second wall cloud to the south of the large one from the previous images. This one only lasted a little under a minute.
  4. Tornado?---You tell me... The NWS didn't count this as a tornado, but it sure looks like one. This formed from the same wall cloud as the needle tornado of image 3, but rapidly became wrapped in rain.
  5. Tornado? part 2---Seconds later, same feature. It looks a little wider and hasn't moved like a rain shaft would. As I said... you tell me whether or not there's a tornado in there. (One of these days I may make an MPEG movie of this feature and if I do... I'll post it on this page.)
  6. Original Wall Cloud---The rain-wrapped circulation from images 4 and 5 is to the left. This is the original wall cloud. It's not at strong as before, the other circulation is starving it.
  7. Small Funnel---A little while later, this small funnel tried to spin up, but had no luck.
  8. Mangum/Brinkman Tornado---The image formerly on my front page, this tornado formed unexpectedly to our west as we drove towards other storms west of Altus. It lasted approximately 4 minutes. The next 5 images are of this tornado.
  9. Pic 2---The tornado assumes a more stovepipe-like shape.
  10. Pic 3---It lifts a bit, and appears to not be on the ground, but just wait....
  11. Pic 4---The funnel lowers again, and kicks up some dust to its north.
  12. Suction Vortex---Although the funnel has lifted somewhat, a small suction vortex (just underneath the funnel to the right) shows that it's still on the ground.
  13. Occluding Out---Now the tornado has lifted, but forms into some interesting shapes before it dissipates (note the upward curl at the bottom of the dissipating funnel).
