expected in Sumner Strait today into this evening. Current
observations in the area are reporting light winds. Diurnal
heating could increase wind speeds and wind gusts during the
warmer parts of the day. Then later in the afternoon, wind speeds
will decrease as we lose daytime heating.

VFR with 3500 ft ceilings and 6 mile or more vis or better
reported at Wrangell. Some showers possible through noon with
