FIRE WEATHER WATCH IN EFFECT FROM WEDNESDAY MORNING THROUGH THURSDAY EVENING FOR THE SAN LUIS OBISPO/SANTA BARBARA INTERIOR MOUNTAINS INCLUDING THE SANTA Lucias AND ADJACENT FOOTHILLS DUE TO GUSTY NORTHEAST WINDS, VERY LOW RELATIVE HUMIDITY, CRITICALLY DRY FUELS, AND HOT TEMPERATURES WITH LARGE VERTICAL PLUME GROWTH POTENTIAL. .A strengthening upper level high pressure system combined with weak offshore flow will bring another heat wave to the region through at least Thursday.

The hot and unstable conditions will bring very high mixing heights (similar to the Bridge Fire event) which will create favorable conditions for large vertical plume growth with any new fires.
