The prior forecast remains valid with only minor changes to the Elevated area over parts of the LA Basin. Morning observations show offshore gusts of 30-40 mph are ongoing across terrain-favored areas of the LA Basin. This is expected to gradually diminish through the morning and afternoon as the offshore pressure gradient and easterly flow aloft weaken. Still, low humidity (RH values from 10-20%) and the strong gusts appear likely to support a continued fire-weather threat into this afternoon. The most likely corridor for sustained elevated to near-critical conditions will remain over the terrain-enhanced features of the western LA Basin and farther south into the San Jacinto to Laguna mountain ranges. Fire concerns should then abate overnight as upper-level support and offshore gradients weaken further. See the prior discussion for more information. ..Lyons.. 01/10/2025 .PREV DISCUSSION... /ISSUED 0140 AM CST Fri Jan 10 2025/ ...Synopsis... A series of positively tilted mid-level troughs will progress southeastward across the western and central CONUS today, supporting the maintenance of surface high pressure across the Inter-mountain West. Dry offshore winds should continue off of the southern California coastline through at least the morning hours. However, the pressure gradient should diffuse through the day as the first in a series of mid-level troughs moves away from southern California. Elevated to Critical dry and windy conditions should be most prevalent during the morning, and will wane during the afternoon hours. The best chance for any Critical conditions (i.e. 20+ mph sustained offshore winds with 15 percent or less RH) will be across the San Jacinto to Laguna mountain ranges. ...Please see www.spc.noaa.gov/fire for graphic product... $$
