Decisions based on Forecasts?

Stein Fire - morning of August 30 8:30 - crews to fire 9:30 - crews ordered evacuated from the fire - aircraft ordered to land and hold 10:30 - all crews in safe areas and aircraft on the ground 11:00 - frontal passage 11:30 - crews and aircraft operational

An observer near the fire reported the frontal passage at approximately 11:00 am. His report of conditions with and following the front were very close to forecast conditions. Increasing Southwesterly winds at 30 to 40 km/h shifted to North with the front and increased to 40 to 60 km/h with gusts to 80 km/h. The winds tapered off to 20 to 30 km/h approximately 1/2 hour after the frontal passage and shifted to the Southwest. Thunderstorms accompanied the front.

Conditions on the fire were chaotic with the Frontal passage Conditions on the fire were chaotic with the Frontal passage. Strong winds created fire whirls, flying debris and blew down several trees. Two crews would have been in imminent danger had they remained on the fire.
