Among the hazards for those living or working in immediate or near coastal areas is that of coastal flooding. Coastal flooding occurs when ocean water moves into coastal areas, and is fundamentally different from flooding due to heavy precipitation, sometimes termed fresh water flooding. Fresh water flooding can occur in any area, but is more likely in low lying areas and near rivers or streams, not necessarily near the coast.
There are two major factors to consider when assessing the risk of coastal flooding. The first is the state of the tide, and the second is the presence of strong winds from an onshore direction.
The preceding article provides detailed information about many apps for smartphones, tablets and laptops to help ocean voyagers with passage planning. These apps bring the output of mathematical models of the atmosphere to mariners in a useful, widely used format. Since mathematical models are the core of these apps, it is worth discussing the general theory behind them

READING THE GLASS: A Captain's View of Weather, Water, and Life on Ships
Works about the sea are a peculiar literary institution. The best of them offer a harsh unblinking portrait of the mariner's essential solitude and isolation. Elliot Rappaport, shipmaster, scholar, gifted writer, does this with perception and compassion. But he also provides much more: a richly embroidered text that interweaves his narrative with a tale of wind and weather and the history of seafaring and exploration. Of particular note is his understandable obsession with storms at sea as well as his survey of the broader story of the science and art of meteorology. He takes his book's curious title, by the way, from the practice of bygone skippers in sail to reckon barometric pressure from the height of a glass-enclosed column of mercury.
