CAWFE simulations of the winds in the vicinity of the ignition of
the Napa wildfires (Atlas Fire, Partrick Fire, Nuns Fire, Tubbs
Fire, and Pocket Fire) at 8 PM ( ~ 1-2 hr before several ignitions
were reported). The underlay shows the first higher resolution map
of fire extent at ~ 3 AM from the Visible and Infrared Imaging
Radiometer satellite (courtesy of University of Maryland and USDA
Forest Service Remote Sensing Applications Center). The
upwind edge of the fires lie near locations with ~70-90 mph
near-surface winds. (All times local).
These CAWFE simulations use 4 nested domains. The innermost
domain, domain 4, - shown above - has 370 m horizontal grid
spacing.
