| 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: | ||||||||||||||||||
*** No Burn Day *** Not much change again as strong high pressure remains over the west coast with widespread smoke impacts. Maybe a few degrees of cooling, but the smoky and hazy skies will be the main weather consideration again. 24hr Outlook *** No Burn Day *** Should start to see more delta winds and a slow cool down as we move forward. This will translate to less smoke impacts in those areas closes to the delta, but smoke will be around well into the week. The real change still on track for late this week. Until then, expect more of the same since the smoke has no place to go. |
