Record Flooding at Annapolis

The table uses MHH, so to convert to MLLW add 1.43 feet  https://tidesandcurrents.noaa.gov/datums.html?id=8575512 

In addition to how sea level is measured, you have to be careful about the times, since many of the records for the tide gauge are in UTC (aka Greenwich or Zulu).

The local paper is reporting two prior high water marks that I cannot verify:

1.  "third-highest record of 4.98 MLLW set in 1955." NOAA says 4.583 feet on the hourly record (see the graph below), and it was Hurricane Connie.  Several NOAA listings give the height as 4.98, which I think is a typo.

2,.  "a 1993 storm ...  second-highest downtown flood recorded, with 6.17 feet above MLLW."   This is actually 1933, the Chesapeake-Potomac hurricane
