March 2013 Nor'easter by the Numbers
A two-day coastal storm left flooded streets but no widespread damage.
So how bad was the flooding from this week's coastal storm?
The new tide gauge recently installed at the Bayside Center on the bay between Fifth and Sixth streets provides a great resource for determining exactly where the storm falls in comparison to others.
The gauge showed a high reading of 4.49 feet at 4:06 a.m. on Thursday, March 7. That puts tide levels from this week's storm less than a foot below the damaging November 2009 nor'easter but almost three feet below October's record Superstorm Sandy.
The tide readings are based on 1988 datum, which is the first column of the chart below. These readings show tide levels above and below an average mid-tide.
The middle column of the chart is based on 1929 datum and matches the base flood elevation criteria that Ocean City property owners know from their flood insurance elevation certificates.
The third column in the chart above represents tide levels above an average low tide (mean low water). These are typically the readings people hear when weather forecasters talk about storm surge.
|NAVD 1988||NGVD 1929||Mean Low Water|
|Sandy, Oct. 29, 2012||7.25||8.50||10.02|
|Storm of March 1962||6.35||7.60||9.12|
|Dec. 11, 1992 Storm||6.23||7.48||9.00|
|Oct. 31, 1991 Storm||6.00||7.25||8.77|
|Gloria, Sept. 27, 1985||5.75||7.00||8.52|
Nov. 11-14, 2009 Storm
|March 2013 Storm||4.49||5.74||7.26|
|Typical High Tide||2.00||3.25||4.77|
Six feet above mean low water generally signifies "minor flooding," seven feet "moderate flooding" and eight feet "major flooding."
