Initial Impressions:  The low-level flow just offshore of Cape Fairweather was sampled in conditions of weak onshore (SSW) flow.  The general impression was that the terrain effectively caused both low-level blocking and a shallow land breeze (due to presumably katabatic processes) near Pt. C. Whatever the cause(s), the winds near C were from the ESE below about 800’.  The vertical and horizontal extent of the easterly flow was surveyed (except for on its north side).  Consistently low values of turbulence were present.  One problem with the data was found: the dewpointer (tdp) was out of adjustment, causing a spurious, high-frequency oscillation with a typical swing of .4 C in dewpoint.
