.DISCUSSION...

Surface conditions remain too moist to prompt any critical fire 
weather conditions through the work week. Wednesday will see 
isolated to scattered thunderstorms which may create gusty outflow
winds, produce localized heavy rainfall capable of creating burn 
scar flash flooding and debris flows, and ignite new wildfires. 
Early next week as conditions dry out, a few isolated critical 
fire weather areas may develop, but there is no imminent risk of 
widespread red flag conditions.
