'***See correction of 20:30 UTC June 22 at the end of this post: we no longer classify this event a meteotsunami.***

ORIGINAL POST:
The band of thunderstorms that crossed the Washington, D.C., area earlier today generated a modest meteotsunami off the coast of Delaware and New Jersey.

Here's the record from the tide gauge at Cape May, NJ (the red line is the actual water level; the black line is water level with the tide removed). The meteotsunami is about 0.5 meters peak-to-trough.

CORRECTION: 
A meteotsunami, like all tsunamis, is a propagating wave train. While the sea-level anomaly shown in the figure did show up on other nearby tide gauges, it did not advance far beyond the mouth of Delaware Bay. In particular, it did not reflect from the shelf edge to come back to threaten the coast in the manner of the meteotsunami of June 2013. Since it did not propagate far, we cannot call the event a meteotsunami.

The waveform in the figure may simply be the result of wind piling up water down Delaware Bay. It clearly was a weather-induced long-wavelength phenomenon, but, unlike 2013, those waves were not the result of Proudman Resonance across the continental shelf (the atmospheric pressure record from Cape May shows a broad pressure pulse coincident with the waves rather than what was seen in 2013: a pressure pulse preceding the waves by more than an hour). The source area of this event appears to have been too small to sustain a tsunami; the waves rapidly dissipated.

Nevertheless, yesterday was interesting!'
