A hurricane’s deadly forces The combination of water and wind can have catastrophic impacts on nature and man. Learn what these mortal features can do and wild animal control near me how to survive them.
Storm surge is simply the growth in water that floods the shore as water is pushed onshore by powerful winds, and to a much lesser level very low pressure. It is important that you know the tides of the coastal region where you’re located. For example, a lot of locations on the Gulf coast have very little tidal ranges, whereas places on the U.S. east coast have large tidal ranges. It makes a significant difference on the impacts to the coast if a hurricane moves ashore through a low or high tide in a place where the tidal range is large. Today, inland flooding causes the largest loss of life. In the past, when hurricane forecasting technology was not as sophisticated, storm surge was the motive for the majority of deaths. It’s best to leave a structure 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 coast that batter other structures further inland. Houses built on stilts have a much greater survivability from surge damage. Nevertheless, it’s wise not to “ride out” a hurricane and evacuate to a safer location.
Hurricanes produce strong sustained winds that have the capability of destroying structures and toppling trees and power lines. The Saffir-Simpson hurricane scale gives an estimate on the kind of wind damage which can be expected with various categories of hurricanes. A significant hurricane is considered a class 3 or higher. Strong winds can blow in garage doors, break windows, or lift roofs off of homes. Be sure that you have shutters or plywood to cover windows properly 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, evacuate to higher ground. If you do not have a basement, find a little room on the lowest floor with no windows near the middle of the house to stay.
Tornadoes are many times associated with land falling tropical cyclones. The majority of the tornadoes happen within 24 hours of land fall, even though it’s possible for tornadoes to still occur a couple of days later still associated with the circulation. The largest hurricane associated tornado outbreak on record happened with Hurricane Ivan in 2004 with 123 tornadoes. Other hurricanes that produced a substantial tornado outbreak were: Hurricane Buelah (115), Hurricane Frances (103) and Hurricane Rita (101) tornadoes. Contrary to their Midwest cousins, tornadoes on average are weaker in hurricanes. There’s typically a weaker signature on radar and hail almost never accompanies them. Stronger land falling hurricanes have a greater potential to create tornadoes than poorer ones. Tornadoes occur with land falling hurricanes as the storm moves over land and encounters greater low level friction from the property. This slows the wind at the surface greater than higher aloft, adding to vertical wind shear. It’s this increase in wind shear that sets up an environment favorable for tornado development. Follow the same safety guidelines for high winds to safeguard you and your family from the harmful effects of tornadoes.
All hurricanes do not produce severe flooding. There are lots of factors that lead to the flood potential of a hurricane or weaker tropical cyclone. The most important factor is the rate of movement. If a tropical cyclone moves into a region where steering currents from the winds aloft are weak, very heavy rain can 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 affected by the terrain of a location. Mountains cause an additional lift to occur, 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 usually can tap a deeper source of deep layered moisture. Hurricanes which form in higher latitudes have a higher prospect of entraining dry air from mid latitude weather systems limiting moisture. When a tropical cyclone is approaching, understand the potential for heavy rainfall to make flooding or flash flooding where 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 Tropicalweather.net’s article on hurricane preparedness.
