FIRE WEATHER PLANNING FORECAST FOR NORTHWEST CALIFORNIA
NATIONAL WEATHER SERVICE Eureka CA
308 AM PDT Sun Sep 22 2024

...ENHANCED FIRE WEATHER RISK ON HIGH RIDGES DUE TO POOR RH
RECOVERY AND GUSTY NORTHEAST FLOW OVERNIGHT FOCUSED IN THE
WESTERN KLAMATH MOUNTAINS...

...ELEVATED FIRE DANGER MONDAY AND TUESDAY FOR ALL INTERIOR AREAS
DUE TO HOT AND DRY CONDITIONS...

.DISCUSSION...Strong thermal belts have allowed for another night
of poor RH recovery across mid and upper slopes. Hot and dry
weather will continue to build today. By Monday, interior valleys
will most likely see highs above 100 with minimum RH in the
teens. While valleys will maintain good RH recovery around 80
percent, enhanced thermal belts will continue to generate poor RH
recovery along mid and high slopes of 20 to 40 percent. Aside
from moderate north wind right along shore and along the Eel River
Valley today, daytime wind will be generally gentle and terrain
driven. High elevation areas will experience enhanced, northeast
diurnal flow at night with isolated gusts up to 25 mph. More
moderate conditions will return later in the week.
