Water Levels During Hurricane Bret

What this shows is that for these two stations (Yarborough Pass and Rincon del San Jose) which are relatively close together, the water levels seem to be out of phase with each other. The changes in water elevation that we see in the middle-Laguna are not due to tides (gravitational attraction of sun and moon), but because of local wind forcing.

The National Ocean Service has declared that the waters of the Laguna Madre are non-tidal for datum computation purposes. Thus, we only compute a "mean water level" datum for these stations, rather than the full suite of tidal datums.
