“There was a fire in Napa a couple of months ago now that was about 5000 acres, and the firefighting operations basically stopped, At 7:30 or eight PM. Maybe they didn't stop entirely, but most of them stopped. And the fire grew from like a thousand acres to a bit over 3000 acres overnight.”

The claim, plainly

During a roughly 5,000-acre wildfire in Napa around August 2025, most firefighting operations stopped around 7:30 or 8:00 PM, and the fire grew from approximately 1,000 acres to over 3,000 acres overnight.

Assessment

Stuart Landesberg correctly identifies the general timing, location, and approximate scale of the Pickett Fire in Napa County (which ignited August 21, 2025, and burned 6,819 acres, roughly matching his 5,000-acre estimate). However, two specific legs of the claim are inaccurate. First, the fire did not reach 'over 3,000 acres overnight'; it was mapped at approximately 1,045 to 1,200 acres on the evening of August 21 and stood at 2,133 acres at the end of the overnight operational period on the morning of August 22, only crossing 3,000 acres (3,235 acres) late the following afternoon at 4:07 PM PDT. Second, while daytime fixed-wing aircraft stood down around nightfall (released at 8:21 PM PDT), firefighting operations did not mostly cease: 350 ground personnel actively constructed containment lines through the overnight shift, supported by three night-vision-equipped helicopters conducting water drops until roughly 2:00 AM PDT.

CAL FIRE Incident Archive records confirm the Pickett Fire ignited August 21, 2025, in Napa County and burned an official total of 6,819 acres.
FIRIS Intel 12 and CAL FIRE mapped the fire at 1,045 acres at 5:58 PM PDT on August 21, 2025, and at 2,133 acres at 7:32 AM / 9:26 AM PDT on August 22, 2025, showing overnight growth reached ~2,100 acres rather than over 3,000 acres.
CAL FIRE incident updates confirmed the fire reached 3,235 acres late the following afternoon at 4:07 PM PDT on August 22, 2025, after daytime burning.
CAL FIRE dispatch and briefing logs show fixed-wing air tankers were released at 8:21 PM PDT, but 350 personnel remained active overnight on ground lines, alongside three night-flying helicopters operating until 1:59 AM PDT.
