The Guissona wildfire interacted with nearby storms, causing it to grow significantly and generating big vertical development of the plume. It was started by a harvesting machine. In the early stages, it spread rapidly across unharvested agricultural fields in a northerly direction until it reached a small forested area, whereupon it intensified. In just over half an hour, it had travelled 1,500 metres. At this point, due to the influence of the storms, the direction of spread changed by 90 degrees towards the west, generating a 1.5-kilometre-wide head (the left flank). This enabled the fire to spread at speeds of up to 12 km/h, consuming more than 6,000 hectares per hour, until the storm discharged, causing a change in spread direction towards the south.
