   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHERN CA...

   ...19z Update...
   Confidence continues to increase that strong offshore winds and
   high-end critical fire-weather conditions will be ongoing at the
   start of the period D2/Wed morning. A belt of 25-35 kt mid-level
   east-northeasterly flow, will gradually become more easterly and
   align with a pronounced offshore pressure gradient across southern
   California. This should support sustained 25-35 mph surface winds
   and RH near 10% across the western LA Basin Santa Ana corridors.
   Stronger gusts to 40-50 mph will also be possible across the higher
   terrain. Fire-weather concerns will remain high through the day
   before winds decrease overnight into D3/Thurs. See the prior outlook
   for more info.

   .PREV DISCUSSION... /ISSUED 0208 AM CST Tue Jan 14 2025/

   ...Synopsis...
   A belt of stronger mid-level east-northeasterly flow, along with
   surface high pressure over the Great Basin, will continue to support
   a pronounced pressure gradient across southern California, where dry
   offshore flow will remain a concern for most of the Day 2
   (Wednesday) period. Latest guidance consensus shows at least 25 mph
   sustained winds amid 10-20 percent RH across terrain favoring areas
   from the Ventura Valley to the Laguna Mountains. These conditions
   are most likely during the first half of the period, with Critical
   highlights added to address the wildfire-spread potential.

   Day 3-8 Fire Weather Outlook

   Valid 151200Z - 211200Z

   Widespread and high-end critical fire-weather concerns are expected
   to persist through midweek this week over portions of southern CA. A
   strong upper low and easterly mid-level flow are forecast to develop
   off the Pacific Coast. As the upper low cuts off, mid-level flow
   will align with strong offshore pressure gradients over the western
   LA Basin and mountains through D4/Thur. Winds will then slowly
   weaken through the remainder of the week. High pressure redevelops
   this weekend and additional fire-weather concerns are possible.

   ...Southern CA...
   Strong offshore winds are expected to be ongoing at the start of the
   forecast period D3/Wed morning. Sustained 25-40 mph with gusts of
   45-70 mph and single digit RH will likely support extreme fire
   danger across portions of the western LA Basin and Transverse ranges
   through noon. Critical fire-weather conditions will likely continue
   into D3/Wed afternoon with strong winds and low RH. Offshore
   gradients will gradually weaken into the evening as the upper low
   shifts southeastward. Upper-level flow is also forecast to slowly
   weaken into early D4/Thursday. The winds aloft are forecast to
   become more southeasterly as they weaken. This shift should favor
   less alignment with typical Santa Ana corridors in the LA Basin.
   Still, elevated to critical conditions will likely persist across
   the Santa Monica and Santa Ynez Mountains through D4/Thurs before
   winds weaken below 25 mph.

   Fire-weather concerns will lessen through the remainder of the work
   week as onshore flow returns on the backside of the upper low.
   However, high pressure over the Great Basin is forecast to
   strengthen again this weekend and into week 2, as an arctic air mass
   intrudes the lower 48. This could support another prolonged period
   of offshore flow and heightened fire-weather concerns. However,
   confidence in the strength of any offshore winds later in the period
   is low.
