Here are some 'tornado rarities' with brief descriptions and footage (You might notice a pattern with these...)
As Tropical Storm Harvey made landfall in Belize on August 20, 2011, a tornado spawned in its outer bands would cause severe damage in the town of Crooked Tree. Trees were uprooted and snapped, power lines were downed and zinc roofing was ripped apart. A few small wooden homes were destroyed, including this one where Edward Westby and his wife miraculously escaped injury:
Tree damage
No published rating information is available, but this tornado may have been an F1.
Video of the tornado:
A landspout tornado touching down in a mountainous area in Bolivia in August 2011. The tornado reportedly damaged or destroyed some structures, although little information is available beyond this footage.
On November 16 of the same year, another tornado caused damage in Cochabamba. At least 20 homes were heavily damaged, some of which lost roofs and sustained partial collapse of exterior walls. The tornado was rated F0 due to the homes being poorly constructed, although an F1 rating was likely more appropriate.
Video:
This F1 tornado touched down in Lincoln, Argentina on March 7, 2011, becoming the second tornado to affect the city during its history (the other being another F1 in October 1986). 25 homes sustained partial to complete roof loss, but fortunately there were no casualties.
On another note, La Plata (the one near Buenos Aires) has narrowly missed being hit multiple times, including on July 25, 2011 and April 2, 2013.
