Dramatic footage shows the moment Tropical Storm Rosa hits the town of Yuma in Arizona with powerful winds and rain.
Meteorologist Matthew Strauser filmed a video of the tropical storm, formerly a hurricane before it weakened over the weekend, as it hit his location.
Posting the video to Twitter, Strauser said: “Video showing the moment the suspected microburst in Yuma hits.”
The video shows winds getting progressively stronger over the length of a minute in a storm that has uprooted trees.
A microburst is an intense downward burst of wind and rain from the base of a thunderstorm, that last for seconds to minutes and can be extremely dangerous due to their force.
Hurricane Rosa has affected south western America including California since 30 September; the storm is likely to continue until 2 October.
