…Abnormal ocean water surges are expected along the oceanfront,
inlets, and back bays through the overnight hours…

Air pressure sensor and tidal gage readings in and near the
coastal waters indicate that a weather-generated tsunami has been
triggered by the line of thunderstorms as it moved over the ocean.

Impacts are expected along the oceanfront, inlets, and back bays
from Perth Amboy New Jersey to Fenwick Island Delaware.

Water level fluctuations of several inches to one foot above
normal astronomical tide in localized areas can be expected along
the oceanfront, inlets, and back bays for the next several hours
as a series of surges make their way to the coast.

The duration of this event is uncertain, though similar events
have lasted from several hours to one day. It is not recommended
to return to the water until at least Wednesday morning.

The strong currents associated with these surges could pose a
danger to those in or near the water.

Recommended actions are listed below…

Boat Owners…
Prepare now for the following hazards…
* Strong, unpredictable currents
* Surging up to one foot above normal sea level

Swimmers…Surfers…and Boaters
It is recommended you leave the beach now to avoid the following
hazards…
* Strong currents
* Potentially dangerous surges of water.

This kind of tsunami is generated by abrupt changes of atmospheric
pressure in the causative storm system, which is a line of
thunderstorms that moved over the ocean in this case. The
combination of the air pressure effect on the ocean surface and
the speed at which the pressure disturbance travels can generate
tsunami like waves in certain situations. The National Tsunami
Warning Center is monitoring this event.

Additonal statements will be issued if necessary through National
Weather Service Office Forecast Office in Mount Holly, NJ.
