FIRE WEATHER PLANNING FORECAST FOR NORTHWEST CALIFORNIA
NATIONAL WEATHER SERVICE Eureka CA
334 AM PDT Fri Oct 18 2024

...RED FLAG WARNING IN EFFECT UNTIL 5 PM PDT SATURDAY...

...RED FLAG WARNING IN EFFECT FROM 11 PM THURSDAY TO 5 PM PDT
SATURDAY FOR GUSTY NORTHEAST WINDS AND LOW RH FOR ZONE 264...

...ELEVATED CONDITIONS FOR THE REMAINDER OF THE AREA DUE TO
GUSTY OFFSHORE WINDS AND LOW RH LATE TONIGHT THROUGH FRIDAY...

.DISCUSSION...Breezy northerly to northwesterly winds will
redeveloped along the coast this afternoon, while offshore winds
diminish slightly across the interior. Minimum RH will drop into
the low teens today and remain low through weekend. RH recoveries
at mid elevations will become poorer each night into the weekend
as low as 20 percent in Lake County. Northeast winds are expected
to restrengthen later this evening, concentrated around the rim
of the Sacramento Valley and in well oriented terrain such as the
Russian River Valley and around Clear Lake. Winds will be
strongest at night with peak wind gusts tonight and early Friday
of 25 to 35 mph. Strong winds combined with very low RH will lead
to critical fire weather conditions in southern Lake County. Conditions
will greatly ease again through the weekend and into early next
week with higher RH and much calmer winds.
