...SCATTERED THUNDERSTORMS CONTAINING LOCALLY GUSTY WINDS 
POSSIBLE THROUGH THIS AFTERNOON MAINLY IN TRINITY COUNTY... 

...ANOTHER ROUND OF SCATTERED THUNDERSTORMS LATE TONIGHT THROUGH 
SUNDAY MORNING FOR PORTIONS OF MENDOCINO, LAKE, AND SOUTHERN 
TRINITY COUNTIES....

.While there continue to be some showers around with perhaps a
stray rumble of thunder, the bulk of the lightning activity has
either diminished or shifted to our south and east. That said,
there still may be some new thunderstorm development this
afternoon around in and around Trinity County, and Red Flag
Warnings will continue for those areas. Any storms will be fast-
moving, with only light rainfall, and contain locally gusty
outflow winds. 

Another round of scattered showers and thunderstorms will push
northward tonight into Monday morning, and impact similar areas 
as we saw this morning and last night, mainly in and around
interior Mendocino and Lake Counties, and portions of southeastern
Trinity County. Thus, another Red Flag Warning has been issued for
those zones for late tonight through late Monday morning. These
thunderstorms will once again be capable of causing new fire
starts due to their relatively dry nature and fast-movement, along
with the continued dry fuels and low humidity conditions in place.

...ANOTHER ROUND OF THUNDERSTORMS EXPECTED TODAY FOR PORTIONS OF 
MENDOCINO, LAKE, AND TRINITY COUNTIES....

Another round of abundant lightning activity will develop this 
morning across Lake and Mendocino Counties and then spread 
northward into Trinity County by afternoon. These thunderstorms 
will be dry and capable of causing new fire starts due to their 
fast movement, coupled with very dry fuels and low humidities. 
Gusty and erratic winds may also accompany some storms as rain 
evaporates before reaching the ground.
