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

   ...Synopsis...
   An amplifying mid-level trough will graze the West Coast today,
   resulting in a tightening of the surface pressure gradient across
   southern California, where dry offshore flow will continue to
   support favorable wildfire-spread conditions. By late afternoon,
   widespread 20+ mph sustained winds overlapping with 10-15 percent RH
   will be likely across much of the southern California coastline.
   Across terrain-favoring areas, localized instances of sustained 40
   mph winds (perhaps with higher gusts) and near-single-digit RH are
   possible, warranting the maintenance of Critical highlights this
   outlook.
