New Zealand native Brendan Gully recently went on vacation in the US with three of his friends in search of extreme storms.

The group travelled through part of America’s famous Tornado Alley and braved the elements to witness these storms at first hand. Brendan created this time-lapse of the extreme weather they encountered across Colorado, Wyoming, Nebraska, Kansas, Oklahoma, Texas, and New Mexico. Credit: Brendan Gully via Storyful
