Apocalyptic landscapes were captured by photographers in California, USA, where wildfires raging since last week have created their own weather.
A thunderstorm cell mixed with a pyrocumulus ash column from one of the blazes, bringing erratic winds and lightning before evolving into a hail storm.
This is how the area looked before the storm. The fire has affected more than 23 square kilometres in Lassen County since last Friday, threatening almost 200 households. The mandatory evacuation has been ordered by the authorities.
Two firefighters were injured there while battling another wildfire in the same county - the Gold Fire - at the beginning of the week.
