...RED FLAG WARNING IS CANCELLED...

The National Weather Service in Eureka has cancelled the Red Flag
Warning. 

The Red Flag Warning for the Upper Smith-Lower Klamath Zones has
been cancelled as relative humidity has been high and wind speeds
have been low. Northeast winds are still locally gusty at 
elevations above 4500 ft but can be better handled by a headline.

A drier airmass will move over the region beginning Tuesday but 
wind speeds should remain below Red Flag Criteria.
