The storms produce strong winds that push the water into shore, which can lead to flooding. This is sometimes referred to as a "storm tide." Quick Links and Additional Resources

Adding to the destructive power of surge, battering waves may increase damage

negatively or in a bad way. This was a prime example of low pressure, high winds and high tidal conditions combining.

It is also possible for a negative storm surge to occur, when the wind direction blows the water away from the coast instead, causing the sea level there to drop.

Originally uploaded in Integrating Research and Education:Hurricane Katrina. The water piles up, unable to escape anywhere but on land as the storm carries it landward. As a hurricane’s winds spiral around and around the storm, they push water into a mound at the storm’s center. x�bbd```b``]"9�A$c�d� �l�`�S0��~fۃ��z��E� I����" 5�O�Ȗ� �eb 6�/��7�d����e�6�����`- �az#C�|�Pl�%�I��;�$��o䦫��-� z� In the night of 31 January 1953, a storm in the North Sea caused a storm surge which occurred at the same time as a high spring tide. Storm surge A storm surge is a higher than normal sea level, due to changes in atmospheric pressure and wind, which can result in inundation of roads and coastal property over an extended period. endstream endobj More than 2500 people were killed around the North Sea coastline, including 307 in England and 19 in Scotland. However, storm surge as a killer from the sea is still threatening human being and exerting enormous impacts on human society due to economic growth, population increase and fast urbanization.

Interactive Map Viewer 3. For example, a Category 4 storm hitting the Louisiana coastline, which has a very wide and shallow continental shelf, may produce a 20-foot storm surge, while the same hurricane in a place like Miami Beach, Florida, where the continental shelf drops off very quickly, might see an 8 or 9-foot surge. This makes storm surges very dangerous for coastal regions.

This mound of water becomes dangerous when the storm reaches land because it causes flooding along the coast. There is also a smaller contribution from the low pressure at the centre of the storm "pulling" the water level up, by about 1 cm for every 1 millibar change in pressure.
