451 FNUS56 KEKA 022151 FWFEKA FIRE WEATHER PLANNING FORECAST FOR NORTHWEST CALIFORNIA NATIONAL WEATHER SERVICE Eureka CA 251 PM PDT Tue Jul 2 2024 ...RED FLAG WARNING IN EFFECT UNTIL 8 PM PDT WEDNESDAY FOR ZONE 264... ...HOT TEMPERATURES AND EXTREMELY LOW RH WILL INCREASE FIRE DANGER FOR ALL INTERIOR ZONES THROUGH THE WEEK... .DISCUSSION...A building heatwave will begin to reach full strength today with highs climbing above 100 in the interior. By Wednesday, highs will be solidly around 110 for valleys away from marine influence. Extremely dry RH will accompany the heat with minimum RH below 10 percent. Overnight conditions are already showing little relief with poor recoveries through the week of 30 to 40 percent. Strong northeast winds gusting up to 25 mph along the rim of the Sacramento Valley will continue to bring critical fire weather conditions to southeast Lake County over the next 48 hours. Similar though more isolated northeast winds can be expected each night by Wednesday morning across high terrain, especially in the the Klamath Mountains. With such dry conditions, even gentle terrain winds will promote periods of critical fire weather each afternoon, especially within wind channeled valleys.
