F4 Tornado
Year: 1995
Day: June 8
Country: USA
State: Texas
Area: Pampa
Fatalities: 0
| Reason 1 for being in nearly certainly | Listed as a possible F6 by Thomas P. Grazulis |
Notes:
On June 8, 1995
a violent tornado hit the industrial section on the west side of Pampa
destroying or damaging about 250 businesses and homes.
It resulted in $30 million in damage and was the costliest and the most destructive tornado on record for this town.
It had a three-mile path and was two hundred yards wide.
At its peak
it was rated an F4 on the Fujita Scale.
Out of all the videos taken of this tornado
the most famous came from a local sheriff, Randy Stubblefield
who used his dashboard camera to videotape the twister.
At one point in the video
the tornado lifted and hurled a van and a couple of flattened pick-up trucks into the air.
In spite of the tornado’s intensity
there were no deaths.
Winds of around 250 to 300 MPH were measured using photogrammetry.
F4+ Tornado
Year: 1995
Day: June 8
Country: USA
State: Texas
Area: Kellerville
Highest winds: 201+ mph(Damage)
Fatalities: 0
Injuries: 0
Damage: $50K-500K
Significant Tornado Parameter: 0.5-3
| Reason 1 for being in nearly certainly | Listed as a F5 by Project VORTEX and Thomas P. Grazulis. |
Notes:
Project VORTEX assessed tornado to be F5
one home was so obliterated that the National Weather Service survey likely missed it.
Intense pavement and ground scouring occurred
with only bare soil left in some areas.
F4+ Tornado
Year: 1995
Day: June 8
Country: USA
State: Texas
Area: Allison
Fatalities: 0
Note likely to Upgrade on my tier list
| Reason 1 for being in nearly certainly | Listed as a possible F5 by VORTEX |
Notes:
Because of the personal injuries in Pampa and the unknown extent of these tornadoes a National Weather Service survey was not done.
VORTEX reports from experienced spotters indicated the Allison tornado was one of the biggest and meanest appearing tornadoes they had ever seen.
All sighting reports would place this as an F5 tornado
but due to little interaction with man made structures
the heavy rains and lapsed time to see the site
F4 was as high a rating as could be awarded.
F4+ Tornado
# 36 TVS: Delta V: 189.4 knots (Vrot = 94.7 knots)
#33 Gate-to-gate: Delta V: 176.6 knots (Vrot = 88.3 knots)
Year: 1999
Day: May 3
Country: USA
State: Oklahoma
Area: Cimarron City–Mulhall–Perry
Fatalities: 2
| Reason 1 for being in nearly certainly | DOW recorded maximum wind speeds at 280+ mph. |
| Reason 2 for being in nearly certainly | Well-built homes were swept away and one had a portion of its foundation scoured from the ground. |
Notes:
Officially rated high-end F4.
Tornado reached its greatest intensity while over mostly open terrain and the strongest winds may not have impacted structures.
Town of Mulhall was impacted by only the outer edge of the circulation but still sustained F4 damage.
Well-built homes were swept away and one had a portion of its foundation scoured from the ground.
Storm chasers suggested that the tornado may have been as strong as
or stronger than
the Bridge Creek–Moore tornado.
F4 Tornado
Year: 1999
Day: May 11
Country: USA
State: Texas
Area: Loyal Valley
Fatalities: 1
Note likely to Upgrade on my tier list
| Reason 1 for being in nearly certainly | Body deformation on animals |
Notes:
Officially rated high-end F4
though one survey revealed potential F5 damage.
Two homes were completely swept away
with the debris strewn long distances.
Large pieces of a pickup truck were found 3/4 of a mile away from the residence where it originated
and a 720-foot long stretch of pavement was scoured from a road.
Ground scouring occurred
and numerous mesquite trees were completely denuded and debarked.
A reporter who also witnessed the destruction at Jarrell said “I hadn’t seen anything like that. I couldn’t believe what it did to animals, This was wiped clean, too, but the cattle – their hides had been ripped right off of them. Some of them were missing heads, and some were caught up and entwined in barbed wire.”
Had this tornado touched down in an urban area, the devastation likely would have rivaled that from Oklahoma City or the storm that leveled a subdivision in Jarrell in 1997.
