Red Flag Warning


URGENT - FIRE WEATHER MESSAGE
National Weather Service San Francisco Bay Area
907 AM PDT Wed Sep 30 2020

.Critical fire weather conditions are expected in the coming days
over the Dolan and Glass Fires. Periods of moderate northerly
winds will develop as early as Wednesday evening and last through
Friday. This will combine with very low afternoon humidity and
little or no nighttime recovery along with critically dry fuels.
This wind event will NOT be as strong as the weekend event for
the Glass Fire. However gusty winds and low humidity will create
potentially dangerous fire weather conditions for the Dolan Fire,
especially during the overnight hours when humidity tends to drop
and ridge top winds can be strongest over the Los Padres National
Forest.
