I must be missing part of the web page, for the three factors that appear to be cited are: - winds. - waves, i.e perodic surface phenomena - sea-level rise (ie. the overall mass of water displaced by the storm). Am I correct that you ascribe #3 primarily to barometric pressure as opposed to an overall (DC component if you like) effect of surface wind on water? What the material on the website truly appears to say is that you can have storm surge without an explicit hurricane eye, and that the onset or maximum water level of storm surge need not coincide with an idealised center of the storm. I offer for discussion the example of the lagoon of Venice, where there are no hurricanes as such. It sits at the north end of a narrow sea, at the silted-up mouth of a river, and storm winds tend to be southerly. One sees flood-level tides almost reliably from October to April.

If you look at the bottom paragraph in the web page you cited you will see that low barometric pressure is an important component of storm surge. The first part seems to gloss over atmospheric pressure so if you don't read the whole page you miss a good bit. In any event, the question was, does barometric pressure have an effect on sea state? The answer is yes, it does. BTW, a standard day is defined as 29.92 inches at 70 degrees F. I'd like to see a more factual definition of the height of water rise in a low pressure center than a comparison of water vrs mercury density. There's a good bit more to it than that.
