From the initial National Weather Service alert: > IMPACTS...If fire ignition occurs, conditions are favorable for very rapid fire spread and extreme fire behavior, including long range spotting, which would threaten life and property. There will be a high risk for widespread downed trees and powerlines, as well as widespread power outages. A Red Flag Warning means that critical fire weather conditions are either occurring now, or will shortly. Use extreme caution with anything that can spark a wildfire. So seems the combination of the wind + fire makes for easy and fast fire propagation. The alert/warning in full is a pretty interesting read: https://alerts-v2.weather.gov/search?id=urn%3Aoid%3A2.49.0.1.840.0.3de04a4244a2c6f949edf5cb2902d59f6697b5b1.001.2 https://alerts-v2.weather.gov/search?id=urn%3Aoid%3A2.49.0.1...
