| 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: | ||||||||||||||||||
| *** RESTRICTED FIELDS DAY *** Another morning with very strong stability therefore it's a Restricted Fields Day. Weak ridging today and tomorrow with light winds and pleasant temperatures. Hazy skies also due to the elevated smoke generated by the Caples Fire today. Burning is not recommended. 24hr Outlook *** RESTRICTED FIELDS DAY or Permissive Burn *** Ridge will get displaced starting late Tuesday as an EPAC trough skirts us by for some scattered showers near the CA/OR border late Wednesday. Flow will remain westerly throughout the end of the week which will direct another wave Friday into Saturday with more shower activity. Next weekend however models have been consistent in another North wind event late Saturday into Sunday. Stay Tuned!!!! |
