AS SUCH, RED FLAG WARNINGS HAVE BEEN ISSUED FOR DRY CONDITIONS, CRITICAL LOW RELATIVE HUMIDITY, AND STRONG WINDS TONIGHT THROUGH SATURDAY EVENING...

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. ##################################################################### ## ## ## Complete a discussion for each ECCDA segment below ## ## When done click transmit, product sent as KMTRFWLMTR ## ## ## ##################################################################### ECC010-182330- St Helena ECC Dispatch- DISCUSSION FOR Marin and Sonoma and Napa Counties 420 AM PDT Fri Oct 18 2024 Dry and gusty offshore winds will lead to rapid drying, compressional warming, and poor relative humidity recovery and retention through Saturday with some locations seeing as low as 10%.
