Tsunami Rolls in — Barely

On Saturday morning, phones were buzzing with voice mails, texts and emails warning of a tsunami advisory.

Predicting Abnormally High-Water Events

During periods of rain, tide tables must be adjusted to higher levels than forecast. Here is a high water level forecasting tool...
