north america
argentina experiences frequent tornadoes each year. tornadoes occur in the south american "tornado alley" ("spanish: pasillo de los tornados"), which includes the provinces of entre ríos, córdoba province, santa fe, la pampa and greater buenos aires. the frequency of tornadoes is similar to the one found in tornado alley in north america. however, there is no exact number of tornado occurrences per year, owing to the lack of data. these regions have the most frequent and intense mesoscale convective systems. tornadoes occur between november and april. in this region, which occupies most of the pampas, cold air from patagonia meets warm, humid air from brazil with dry air coming from the andes. when these air masses collide, they can produce intense storms, frequently becoming supercells that can produce tornadoes. with a larger number of convective storms, there is a higher chance that some of these storms will produce tornadoes. most tornadoes are relatively weak and rarely cause deaths. the strongest tornado recorded in argentina occurred in 1973 when a tornado struck san justo, santa fe. the tornado was an f5 on the fujita scale, with winds up to , making it the worst tornado in latin america and the caribbean.

tornadoes have been documented in every u.s. state (not including the non-state territories of guam, the virgin islands, american samoa, and puerto rico) at least once since 1950, although some regions and states are hit by tornadoes far more than others. for example, the average number of tornadoes to hit the states of alaska, rhode island, and vermont is less than one, while the state of oklahoma receives an average of 52 tornadoes per year, and the state of texas is hit with 126 tornadoes in an average year. the state with the most tornadoes per unit area is florida, though most are weak tornadoes of ef0 or ef1 intensity. a number of florida's tornadoes occur along the edge of hurricanes that strike the state. the state with the highest number of strong tornadoes per unit area is oklahoma. states such as oklahoma and kansas have much lower population densities than florida, so tornadoes may go unreported.
