| 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 *** Damp conditions this morning after last night frontal passage. Most valley locations picking up less than a tenth of an inch of rain. A few lingering showers are possible early this morning along the Eastern valley and foothills. Increasing sunshine today but remaining cool with temps in the 60s. Dispersion will remain good under a light Southerly flow. 24hr Outlook *** Permissive Burn Day *** Brief ridging through Tuesday afternoon before another trough brushes Northern California Tuesday night into Wednesday. This next system looks to push a littler further North than Sundays with lightly scattered precip once again the further South you go. However gusty southerly winds are expected. An unsettled weather pattern will remain in place through the end of the week into the upcoming weekend with some more substantial rain possible. Stay Tuned! |
