A small tornado given a rating of F2 hit a mobile home park in the Houston suburb of Deer Park during the afternoon time of July 29, 1971.
The path length was only 1/2 mile. It struck the Stewart subdivision in the SW edge of town. 10 homes were destroyed, 7 damaged. The tornado skipped to the downtown area causing damage to several buildings.
At 1145 EST, a quick-hitting F3 hit parts of Montgomery County, PA. The official path is only 2 miles. The tornado paralleled Limerick Road on its western side and moved right over a housing development called “The Hamlet”. It was a newer development. Per Storm Data, “Of the 27 inhabited houses, 4 were leveled, 16 were damaged beyond repair, 1 under construction was destroyed and only 7 remained liveable. Damage in this development alone was $2 million.”
This tornado made a quick jaunt of nearly 4 miles just north of Scottsbluff, NE on July 26, 1993. It was the strongest tornado of 6 that were confirmed on this day.
Per the NWS Storm Data entry, most of the damage in Granite Falls was caused by F2 and F3 winds speeds. It was officially classified as minimal F4 based on the twisted wreckage of an overturned railroad car.
This tornado not only has the longest path on record for the state of New Hampshire BUT also has the longest path on record for New England.
Fujita researched this tornado family and the influence that microbursts may have had on them. Per Grazulis, “Professor Fujita’s mapping of the Canton tornado family shows how microbursts and/or other downburst-type winds move the tornado from side to side and may influence its intensity. Microburst m2 might have caused the break in the path. Otherwise the event might have been a single tornado. Microburst m6 might have caused the tornado to intensify. Both deaths were in that area.” (Grazulis, 1178)
A significant tornado crossed through parts of Stearns and Sherburne Counties in Minnesota on July 22, 1967. This tornado is officially listed in the SPC Tornado Database with a rating of F2. Grazulis has a rating of F3.
Nine tornadoes are found in the SPC Database for July 21, 1983. The strongest was rated F3 in Ocean County, NJ. The deadliest though was an F2 that briefly hit the northern parts of Hartly in Kent County, DE.
It was called the most damaging Minnesota tornado to date, but Thomas Grazulis in Significant Tornadoes questions that statement. He believes this was a “complex combination of tornadoes and microbursts” and that much of the damage was due to the strong microbursts.
