Stage 1 (≈28 h): wind directions highly variable, causing the fire to constantly shift its head-fire section, growing mainly to south/south-east until it reached Leiteijo stream, increasing its speed. Day 18 at ≈15 h the fire reached location 1. Day 18 at ≈23 h the fire had 4 active fronts, two fronts standing out—one heading east towards location 2, and the other heading south towards locations 3 and 4 Two fire occurrences in a contiguous municipality, day 19 ≈13 h and 14 h were reported. All areal resources that were slowing fire progression towards south were displaced to contain these fires
  19 17 h
Stage 2 (≈7 h): fire reached Odeleite Stream and turned into a major conflagration. Wind speed increased and led to a fast and intense growth towards south with a 10 km fire front and two advanced sections, one heading west towards locations 5 and 6 and the other heading east to location 7. Around 18h30 m the fire was close to location 7. In approximately 3-5 h the fire burned an area greater than the previously consumed in 28 h, traveling a distance of ≈6 km in the west part and 7.5 km in the southeast part. The fire reached its extremities in approximately 7 h Fire reaches Odeleite Stream

Day 20 at ≈2 h the fire was reported at location 8, 15 km distance from the beginning of stage 2 (2 km/h). At ≈2 h 30, the fire front from the west side was heading in direction of location 9. This fire front was being contained with bulldozers, areal and terrestrial resources. Fire was globally controlled in the other fronts. More resources became available from the other fire occurrence. By the end of the day, the highest fire activity was observed at locations 10 and 11, with the remaining sectors consolidated or with favourable evolution. Meteorological conditions became less severe during the night (higher relative humidity and lower temperature) Day 20 at ≈6 h the fire in the contiguous municipality was controlled
   Day 21 at ≈6 h, bulldozers started working between locations 12 and 13, and locations 14 and 13 (fire control line with 14 km length and 20 m wide, in 48 h) preventing fire spreading to location 15, increasing its severity to great extent Wind direction change forecast to north-west, with possible spread towards location 15
