When any district's 0-6 am average PM2.5 is >= 27 ug/m
increasing concentrations will result in a reduction in allocation acres (e.g. 27-28 : 20%, 29-30 : 40%, 31-32 : 60%, 33-34 : 80%) |

Cautionary Comments: | ||||||||||||||||||
*** Permissive Burn Day *** No significant changes to the pattern as the upper ridge remains over the west and the closed upper low spins over soCal/AZ, bringing continued similar warm and dry and calm conditions: winds L+V 3-5mph tending slight northerly, temps 10-15degrees above normal in the upper 70s and even 80s in nValley, and mixing hgts lower at 1,500-1,800ft due to the high pressure. I upped the acres if anyone needs it. Enjoy 24hr Outlook and Extended Period: *** Permissive Burn Day *** On Tuesday, increased instability and mid-level moisture over Tuolumne County brings chance of generating isolated mountain thunderstorms. On Wednesday, a weak shortwave trough will move through bringing chance of isolated showers over northern Shasta County. |
