A parallel scale of storm flood-level stages should supplement the Saffir–Simpson hurricane categories. The relationship between storm intensities and flooding elevations is highly complex. Changes in sea-level, shore positions, formation and extinction of preexisting incised valley networks, the impact of transgression and regression processes on estuaries and their deposits play determining roles in setting the stage for overwash processes. Strandplain progradation followed by erosive shore retreat played a key role in framing certain paralic lakes. Without overwash, sand layers and marine microfossils may be also emplaced by storm-driven currents that enter unobstructed estuaries, inlets and storm breaches. Bioturbation also distorts the storm record. Significant lateral variations in the number and thickness of intercalated sand layers at closely adjacent sites suggest the importance of local differences in sources, transport and preservation processes; in the dimensions, relative positions and accessibility of sand resources inside and adjacent to coastal basins. Variations in the number, thickness, and ages of sand laminae, may not be related to the number of storms and their intensities. This may impair correlations between regionally interpreted “calm” and “intensive” phases. In partial overlap with an assumed “quiescent” storm phase, stable isotope ratios in lacustrine muds impacted by salt water influx reveal frequent hurricane activity during the last 1.5 ka as well. By mimicking effects of reduced storminess, the fewer and thinner sand laminae deposited between ~ 7.0 and 3.4 ka B.P. may be attributed to greater distances of estuarine landward transport by storm tidal currents at times of lower sea-levels.
