Day 1 Fire Weather Outlook

Valid 151700Z - 161200Z

Occasional critical conditions have been observed at the highest
terrain (3-5 kft) sites in southern California. At lower elevations,
elevated conditions are present at a few locations. Given these
current observations and improving conditions expected during the
day, no changes have been made to the ongoing elevated area.

An upper-level ridge and associated surface thermal trough will be
in place across California at the start of the period, with the
trough breaking down to a more quasi-zonal flow pattern, with weak
west-northwesterly flow expected. 

...Southern California...
A weak surface pressure gradient will be in place across California,
mainly during the morning hours. 15-20 mph east-northeasterly
offshore winds are expected, along with critically low RH. With very
dry fuels receptive to fire spread present across the area, an
elevated delineation was continued for the morning hours. Critically
strong winds (20+ mph) may briefly occur along the higher terrain of
the southern California foothills, but the spatially/temporally
constricted nature of these stronger winds precludes a critical
delineation. From the afternoon to the end of the period, surface
conditions will become less favorable for fire spread.
