Smoke:
The low pressure system around southern Oregon area will bring cooler temperatures along with a more unstable atmosphere which may improve dispersal of smoke.  Smoke from the fire is expected to drift to the southwest in the morning then push to the east or northeast in the afternoon.  The air quality index in communities around the fire is expected to be good overall today and tomorrow.  Smoke drift could impact Grants Pass, Cave Junction, Selma, and Provolt but air quality is expected to be good overall.
Fire:
Fire activity yesterday was moderated by favorable weather conditions.  Fire mapping information has not been updated and fire size remains approximately 4,228 acres. Fire activity and growth today and tomorrow is expected to be minimal based on forecasted weather.  Fire behavior will increase as the fire becomes active moves along steep slopes and higher fuel loading concentrations.
