...RED FLAG WARNING FROM 5AM PDT UNTIL 9PM PDT THURSDAY FOR
SIERRA FIRE ZONE 136 & 139 ELEVATIONS ABOVE 5000 FEET DUE TO
THUNDERSTORMS AND GUSTY OUTFLOW WINDS...
.DISCUSSION...
A Red Flag Warning is in effect from 5 am until 9 pm Thursday for
Sierra locations above 5000 feet south of Interstate 80 as
thunderstorm chances continue around 15-30%. A wet/dry mix of
thunderstorms is the primary risk and gusty outflow winds bringing
the potential for new fire starts. Mountain thunderstorm chances
will continue through Friday afternoon, with chances falling below
10% by the weekend. The Valley and Upper Foothills threat has
lessened but still nonzero given the low confidence nature of the
overall forecast.
