Verse of The Day
“E matau ana hoki tatou na wai tenei kupu, Maku te rapu utu; maku te hoatu utu, e ai ta te Ariki: me tenei ano, E whakawa te Ariki mo tana iwi. He mea mataku te taka ki roto ki nga ringaringa o te Atua ora.” (Hebrews 10:30-31)

Articles - Storm Surge
Written by US National Hurricane Center   
Friday, 13 April 2007

Click for larger Storm Surge imageStorm surge is simply water that is pushed toward the shore by the force of the winds swirling around the storm. This advancing surge combines with the normal tides to create the hurricane storm tide, which can increase the mean water level 15 feet or more. In addition, wind driven waves are superimposed on the storm tide. This rise in water level can cause severe flooding in coastal areas, particularly when the storm tide coincides with the normal high tides. Because much of the United States' densely populated Atlantic and Gulf Coast coastlines lie less than 10 feet above mean sea level, the danger from storm tides is tremendous.

The level of surge in a particular area is also determined by the slope of the continental shelf. A shallow slope off the coast (right, top picture) will allow a greater surge to inundate coastal communities. Communities with a steeper continental shelf (right, bottom picture) will not see as much surge inundation, although large breaking waves can still present major problems. Storm tides, waves, and currents in confined harbors severely damage ships, marinas, and pleasure boats. Coastline with a gentle slope
