of the TideTracker to be affected. The following condi-
tions, either separately or together, reduce the accuracy
of the TideTracker:
7EATHER
The mathematics of tidal predictions assume moderate
weather conditions. However, hurricanes and their asso-
ciated winds may cause the tides to dramatically ex-
ceed the mathematical predictions. It is not uncommon
for a "storm surge" to cause high tides which are 10 to
15 feet higher than the predictions. In these kinds of
situations, it is best to listen to the weather broadcasts
provided by the National Weather Service on the ma-
rine VHF band; the NWS will sometimes estimate the
additional tidal height due to storm surge conditions.
'EOGRAPHY
Whenever the topology of the coast line is changed, the
height of the tides may also change. These changes
may be man-made (such as the construction of a break-
water or the dredging of a channel), or they may be
caused by a natural phenomenon, such as the breaching
of a barrier beach by a storm, or they may simply be
the consequence of the natural erosion of the coastline.
In situations like these, the mathematics of the Tide-
Tracker may lose accuracy, because the underlying
mathematics of prediction at the location have changed.
3UMMARY
The best way to get maximum accuracy from the Tide-
Tracker is to apply good judgement and common sense
when using it. In stormy and windy conditions, realize
that the tide predictions may be grossly affected.
