At around noon today, the following report popped up on WatchDuty, labeled as the Inciweb morning report.
Seems like the spot fire was dealt with and while the fire is expanding they are handling areas with "slopover":
"Morning Update from InciWeb:
Size: 2354 acres
Containment: 0%
Total Personnel: 406
Structures Threatened: 149
The Vista Fire experienced significant growth overnight. A heat advisory is in effect until 9:00 pm Thursday night which will cause hot and dry conditions across the fire area. The weather, deep terrain and very dry fuels will contribute to an anticipated increase in fire behavior this afternoon. Crews will focus on establishing an anchor point on the NW side of the Vista Fire to begin laying containment lines. Air resources are being used to slow the growth of the fire.
Last night, quick reaction forces (QRF) consisting of two heavy helicopters dropped 60,000 gallons of water, cooling the fire area and aiding fire fighters in holding the fire’s edge.
Along the northwest flank, the fire is holding in Stockton Flats. Slopover did occur on the western flank but was easily contained as the fire is moving through a sparsely fueled area. The eastern flank skirted the 2023 Nob Fire scar which has kept eastern spread to a minimum. Last yesterday afternoon, one spot fire occurred about a mile east from the fire’s edge. It was quickly addressed with water drops, and ground crews will hike into the area during today’s operations. The majority of growth occurred along the south, southeast edge of the fire with an increase of 1200 acres toward Coldwater Canyon.
Today, firefighters will continue suppression efforts from the air and ground looking for opportunities to create containment lines in the rugged, steep terrain. More fire resources are arriving and will increase the capacity to contain the Vista Fire.
