...FIRE WEATHER WATCH IS CANCELLED FOR DRY THUNDERSTORMS AND
GUSTY OUTFLOW WINDS FOR FIRE WEATHER ZONES 469 AND 470...

The National Weather Service in Elko has cancelled the Fire
Weather Watch.

Isolated dry thunderstorms are expected to reach into southern 
469 and 470 and will still pose a hazard. However, the amount and
coverage of these thunderstorms is not sufficient to warrant any 
further headline products. Thus the Fire Weather Watch is 
cancelled and is no longer in effect for these zones.
