context_page_description: This is a list of weather records, a list of the most extreme occurrences of weather phenomena for various categories. Many weather records are measured under specific conditions—such as surface temperature and wind speed—to keep consistency among measurements around the Earth. Each of these records is understood to be the record value officially observed, as these records may have been exceeded before modern weather instrumentation was invented, or in remote areas without an official weather station. This list does not include remotely sensed observations such as satellite measurements, since those values are not considered official records.
caption: The Tri-State Tornado holds many records, including the longest known tornado track, fastest speed for a significant tornado, and the deadliest tornado outside of Bangladesh.
