Photos: Salmon Club Boat Ramp, NW Maritime Center Pier, Salmon Club Boat Ramp (total water level)
Predicted (Astronomical Tide) Water Level 9.5’, Observed Tide Gauge Level 10.1’ (relative to MLLW)
Wind: ESE at 7 kt
Wave height at Salmon Club boat ramp estimated at 1’
Minimum atmospheric pressure 1002.3 mb; which is 15.2 mb below average
Observed Total Water Level @ Boat Ramp was between 10.4’ and 10.9’ (relative to NAVD88), which is 11.5’ and 12.0’ relative to MLLW
Wave runup = Observed total water level –observed tide gauge = (11.5 to 12.0) –10.1’ = 1.4’ to 1.9’
