The combination of water and wind can have catastrophic impacts on nature and man (Read Full Report).  Learn what these mortal features can do and how to survive them.Storm surge is just the growth in water which floods the shore as water is pushed onshore by powerful winds, and to a much lesser degree very low pressure.  It’s important that you be aware of the tides of the coastal region where you’re located.  By way of example, a lot of places on the Gulf coast have quite little tidal ranges, whereas places on the U.S. east coast have large tidal ranges.  It makes a substantial difference on the consequences to the shore if a hurricane moves ashore through a low or high tide in a place where the tidal range is large.  Today, inland flood causes the biggest loss of life.  Before, when hurricane forecasting technology was much less complicated, storm surge was the motive for the majority of deaths.  It’s ideal to leave a construction that could be impacted by the storm wave of a hurricane.  The force from sea water is very powerful and can destroy a home easily.  High waves take the debris from destroyed buildings which are on the shore that batter other structures further inland.   Nevertheless, it’s wise not to”ride out” a hurricane and evacuate to a safer place.Hurricanes create strong sustained winds that have the capability of destroying structures and toppling trees and power lines.  The Saffir-Simpson hurricane scale provides an estimate on the kind of wind damage which can be expected with various categories of hurricanes.  A significant hurricane is thought to be a class 3 or higher.   Strong winds can blow off in garage doors, break windows, or lift roofs from homes.  Be certain that you have shutters or plywood to cover windows correctly during a hurricane.  Also, know how structurally sound your roof and garage doors are so that they won’t fail in case of high winds.  The safest place to stay is in the basement to protect you and your loved ones from high winds.  If you’re in a flood zone, then evacuate to higher ground.  If you don’t have a basement, then find a little room on the bottom floor with no windows near the middle of the home to stay.TornadoesTornadoes are often associated with land falling tropical cyclones.   The majority of the tornadoes happen within a day of land fall, even though it’s potential for tornadoes to still happen a couple of days later still connected with the circulation.  The most significant hurricane associated tornado outbreak on record happened with Hurricane Ivan in 2004 with 123 tornadoes.   Contrary to their Midwest cousins, tornadoes on average are poorer in hurricanes.  There’s typically a poorer signature on radar and hail nearly never accompanies them.  Stronger land falling hurricanes have a greater potential to create tornadoes than poorer ones.  Tornadoes happen with land falling hurricanes as the storm moves over land and experiences greater low level friction against the property.  This slows the wind at the surface greater than higher aloft, adding to vertical wind shear.  It’s this growth in wind shear that sets up an environment favorable for tornado development.  FloodingAll hurricanes don’t produce severe flooding.  There are lots of factors that lead to the flood potential of a hurricane or poorer tropical cyclone.  The most important element is the rate of movement.  If a tropical cyclone moves into a region where steering currents from the winds aloft are feeble, very heavy rain may result.  It’s possible for the tropical cyclone to be almost stationary for days resulting in very heavy rainfall amounts of 40 to 50 inches or longer.  Rainfall amounts are also influenced by the terrain of a place.  Mountains cause an additional lift to happen, improving rain rates on the windward slopes.  The surrounding environment where the hurricane forms is another thought.  If a hurricane forms in the deep tropics, it generally can tap a deeper source of heavy layered moisture.  Hurricanes which form in higher latitudes have a higher prospect of entraining dry air from mid latitude weather systems restricting moisture.  When a tropical cyclone is coming, understand the possibility of heavy rainfall to make flooding or flash flooding in which you reside.  Summary The best way to endure the effects of a hurricane is by staying informed.  For more on how to prepare before a storm strikes, check’s article on hurricane preparedness.
