SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS

SALEM FORESTRY WEATHER CENTER

OREGON DEPARTMENT OF FORESTRY



ISSUED: Monday, February 14, 2011       7:50 AM      Jim Little



1.  DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625



A low pressure system off the northern California coast is headed northeastward toward Vancouver Island this morning.  The low is embedded in a broad cold trough is located over the northern Pacific Ocean.  This is giving a generally southwesterly flow aloft over the region.



Mixing heights should be fairly high today and smoke dispersal conditions generally good.  Strong winds may inhibit plume development however.



With the renewed rainfall and anticipated lowering snow levels after today we will suspend writing daily forecasts beginning this afternoon.  Forecasts will resume when burning conditions improve and activity increases.  In the meantime individual burns may be handled by calling the Smoke Management forecast desk in Salem at 503-945-7401.

2.  DISPERSION



MONDAY



Transport wind SSW to SW at 35 - 55 mph.



Surface wind S to SW at 20 - 36 mph.
