World's Wildest Weather

Tornado Terror (1x4)

:

A storm chaser finds himself caught up in the eye of the widest tornado in recorded history, as he and his crew narrowly escape with their lives, whilst the county sheriff recalls how he and his colleagues followed the tornado's path in order to help its victims. Also: Hurricane Katrina through the eyes of experts; and shocked locals wake up to snow instead of sun on the beaches of Spain and Italy.
