Service.

.DISCUSSION...West to southwest low level flow is producing low
clouds and visibility along the western slopes of the Wrangell
Mountains. Conditions along the Nabesna Road southward to the SAR
location should be quite a bit better due to position on the lee
side of most of the mountains. In fact, would think VFR conditions
prevail in the valley at SAR location, with low clouds/vis 
sitting in the mountains just to the west. Expect conditions to
hold steady this afternoon and evening. Low level flow will shift
to light northerly after midnight tonight, which will bring some
lower conditions to the SAR area. These will linger through
Tuesday morning, but then expect improving conditions region-wide 
through the day.
