Keep them at a higher level, protected from flood damage. If you live in an area that is subject to flooding, do not store your important documents in the basement.You may be instructed by local authorities to shut these off.

Learn how to turn off the gas and electricity in your house.
This approach requires specific instructions from your local emergency officials. Sandbags are a valuable tool to prevent water from entering your home.Identify any vulnerability and repair it. Check your house and land for any potential dangers related to flooding.Such a surge of high water topped by driven by hurricane-force winds can be devastating to coastal regions, causing severe beach erosion and property damage along the immediate shoreline. As the storm approaches the shore, the greatest storm surge will be to the north of the low‐pressure system or hurricane eye. The surge is always highest in the right‐front quadrant of the direction in which the storm is moving. Water rise can be very rapid, posing a serious threat to those who have not yet evacuated flood‐prone areas. The storm surge arrives ahead of the storm center's actual landfall and the more intense the storm is, the sooner the surge arrives. Storm surge will inundate coastal floodplains by dune overwash, tidal elevation rise in inland bays, and backwater flooding through coastal river mouths. Shape and characteristics of coastline featuresĪ shallow slope has the potential for a great more intense storm surge to develop than a sharp steep slope.The maximal storm surge for any given area is complex as it can be affected by: The impacts of low barometric pressures are minimal on surge when compared to the wind-driven forces. Storm surge is produced when water is pushed toward the shore by the forces of winds moving cyclonically around a storm. At least 1500 persons lost their lives during Katrina and many of those deaths occurred directly, or indirectly, as a result of storm surge. Hurricane Katrina in 2005 is a prime example of the damage and devastation that can be caused by the surge. In the past, large death tolls have resulted from the rise of the ocean associated with many of the major hurricanes that have made landfall.
DangersĪlong the coast, storm surge is often the greatest threat to life and property from a hurricane. Storm surges can cause significant flooding particularly when it occurs in relation to normal high tide. Storm tide is defined as the water level rise due to the combination of storm surge and astronomical tide (thus it is an accumulative level). Storm surge is sometimes confused with a storm tide. This is over and above the predicted astronomical tide. Storm surge is an abnormal rise in water generated by a storm.
