Critical to extremely critical fire weather conditions are expected Tuesday morning along the southern California coast. An unseasonably strong surface high across the northern Great Basin will maintain a robust offshore pressure gradient along the southern CA coast for much of Tuesday and into early Wednesday (see the current D1 Fire Outlook for additional details regarding the synoptic regime). Recent guidance continues to suggest that the LAX-DAG gradient should peak sometime during the 12-17 UTC period Tuesday morning at around -9 to -10 mb. A gradient of this magnitude typically supports wind gusts within the coastal terrain between 50-70 mph, though localized stronger gusts appear possible based on some high-res solutions. By early Tuesday morning the offshore flow regime will be well established with 12 hours of preceding downslope warming/drying. Not only will this support more widespread areas of single-digit RH values (and extremely critical fire weather conditions), but should also promote rapid curing/drying of 1 and 10-hour fuels. Consequently, the greatest fire weather threat will likely emerge Tuesday morning. Recent ensemble guidance and high-res deterministic solutions suggests extremely critical conditions will be most widespread across western Los Angeles and eastern Ventura counties within the San Gabriel and Sierra Madre mountains, though localized extremely critical conditions will be possible further south along the southern CA coast. ..Moore.. 12/09/2024 ...Please see www.spc.noaa.gov/fire for graphic product... $$
