On the map of the Burro Fire, above, the red and brown squares on the north and southeast sides indicate new growth Tuesday and Tuesday night. The red line was the perimeter early Tuesday morning. The white line shows where it was early Monday morning.

Firefighters battling the Burro Fire northeast of Tucson, Arizona were also fighting extreme heat again Tuesday. On the southeast side of the fire they successfully kept the fire north of Redington Pass Road and protected ranch buildings in the area.
On the northeast side steep, rugged terrain and a lack of roads means directly confronting the fire will be very difficult, at best. For now they will rely mainly on air resources to slow the fire’s progress in this area. Contingency plans are in place, should fire activity become a threat to infrastructure or other resources.
The Incident Management Team said Wednesday morning the fire had been mapped at 23,238 acres, growth of more than 4,000 acres from the day before.
Resources assigned to the fire include 594 total personal, 14 hand crews, 33 engines, 19 water tenders and 7 helicopters. The number of air tankers varies throughout the day.
Evacuations are still in effect along the Catalina Highway from Mile Marker 0, north including Summerhaven.
The weather forecast for Wednesday at the 4,000-foot level on the Redington Pass Road where firefighters are presently working predicts 102 degrees, 12 percent relative humidity, and northwest winds at 12 mph gusting to 17.

In the video below, I don’t know about a “storm”, but the Burro Fire, like many rapidly spreading intense fires, did create a pyrocumulus cloud (in the left part of the image).
