Figure 3. A large fall southeasterly gale produced a storm surge (the separation between the predicted tide in blue and the recorded tide in red) of about 2 feet (green line) in Portland Harbor around 16:00 on the October 28th, 2006. Waves recorded by NOAA Buoy 44007 in outer Casco Bay on October 29th reached 20 feet in height. On October 29th as the storm passed, sea level did not rise to the predicted level. Around 16:00 on the 29th, sea level was about a foot lower than predicted. Times shown are in local standard time (LST) and elevations are in feet relative to mean sea level.
