Tom Batey, administrator of Kauai County, suggested damage study sites during two research tours in Kauai. Log in to renew or transfer your service, Supply Chain Responsibilities & Disclosure. . Impacts: Tornadoes spawned by hurricanes are typically short-lived and relatively weak, but they can still cause localized damage and pose a threat to life and property. Exceptional inland damage can result from a number of meteorological and topographical scenarios. It had been blocked from turning eastward into the Atlantic by a high-pressure system (Figure 1). 6 hours before landfall: There will be 90 + mph winds,the storm surge has advanced, and it will be nearly impossible to stand upright outside. The rainfall caused massive stream flooding as well. A normal ocean tide is about two feet tall. However, most hurricanes typically lose their hurricane characteristics after traveling less than 100 miles inland. (Color for this figure is available in the online version of this paper. Additionally, changes in atmospheric conditions may affect the frequency and paths of future storms, with possible implications for inland hurricane penetration and associated impacts. (B) Damage in localities in western Long Island, New York. Additionally, ongoing research and advancements in hurricane forecasting can help inform policy decisions and guide targeted preparedness efforts. Infrastructure damage: Coastal infrastructure, such as roads, bridges, and buildings, can be severely damaged or destroyed by hurricane-force winds, storm surges, and flooding. Hurricane Ike made landfall near the north end of Galveston Island as a Category 2 hurricane. Ocean Springs was in the international spotlight following Hurricane Katrina's landfall on August 29, 2005. The northwest (left) section of Fujita's wind map of Hawaii (Figure 5) details the interaction of Hurricane Iniki's winds with Kauai's rugged topography. What factors determine how far inland a hurricane can go? How far inland do hurricanes go? Hurricanes can travel up to 100 - 200 miles inland. In most cases, hurricanes deteriorate as they move inland away from oceanic sources of moisture or into the cooler waters north of the Gulf Stream. The Susquehanna River discharge reached 1130 ft3/s (1919 m3/s), which is the greatest level in 185 years. Coch (2012) showed how topography increased rainfall in southern New York and New England during Hurricane Irene (2011). The meteorological history of the New England Hurricane of September 21, 1938. Hurricane Camille made a landfall in Mississippi on 17 August 1969. This paper deals only with the inland conditions in each of these storms. How far inland do hurricanes go in Texas? As long as the storm passes over calm, warm water, there is a good possibility that it will grow to be a tropical storm. The specific hurricanes considered here are Tropical Storm Agnes (1969), Hurricane Iniki (1992), Hurricane Camille (1969), Hurricane Hugo (1989), and the New England Hurricane of 1938. Two hours later, Victor Jones was faced with massive wind damage in his county, far inland from Hugo's landfall. Since hurricanes develop in the ocean, it is easy to detect the coming of a hurricane before it hits inland. Record flooding occurred on New England streams (Figure 16E). He stated that gusts on ridge tops, slopes with SW orientations, and gaps that funneled the wind suffered the most severe blowdowns. doi: https://doi.org/10.2112/JCOASTRES-D-20A-00002.1. Hurricanes in the Atlantic ocean however, often pose a much greater threat. Hurricane Irene (2011)A hydrological catastrophe in the northeast U.S. (Color for this figure is available in the online version of this paper. Waves did most of the damage along the coast. There was greater damage on the right side of Hugo's eyewall and great damage inland in Sumter County (Sheffield and Thompson, 1992). As many as 250 million trees were downed in a few hours. Thanks also go to the several people who provided archival photos of storm damage. (Color for this figure is available in the online version of this paper.). Even if you have ventilation, never use a generator indoors. This tree destruction was a function both of the wind strength and persistence, as well as the antecedent rainfall. Winds can be channeled through passes on mountainous islands, like Kauai, to cause massive destruction on the lee side (Hurricane Iniki, 1992). (A) Shriners Club. Radar images of Hurricane Hugo as it moved inland. The open expanse of a century's hazard building may now be rectified. Jet Propulsion Laboratory - California Institute of Technology, NASA, 17 Oct. 2012, www.jpl.nasa.gov/news/news.php?release=2012-329. Spiral rainbands: Bands of showers and thunderstorms that spiral outward from the hurricanes center, extending hundreds of miles and producing gusty winds and heavy rain. Major damage to house roof decking. Winds reached 130160 mi/h (209257 km/h), primarily in areas where winds were channeled through valleys (U.S. Department of Commerce, 1993). As a historical comparison, on September 8, 1900 the Galveston Hurricane of 1900 landed along a path similar to Ike's, bringing with it a storm surge that inundated most of Galveston Island, then Texas' largest city and a major U.S. port. This may be the eye of the storm hitting landfall, which means strong winds and rain will resume shortly. Even when left outside, keep generators away from doors and windows and at least 10 feet away from your home. Coconut Creek (Florida), ISSN 0749-0208. Flood levels continued to rise, and the state capital at Harrisburg, Pennsylvania, was especially inundated on 24 June (Figure 3). After the storm, coastal engineering structures were seen as a way to increase beach width and stabilize storm-cut inlets (U.S. Army Beach Erosion Board, 1946). Hurricanes are common in the eastern Pacific, but they are far less common in the Hawaiian Islands. Steering winds: Atmospheric circulation patterns can steer a hurricane inland, with its remnants continuing to produce heavy rainfall and gusty winds. As it crossed Virginia and West Virginia, on the night of 19 August 1969, rainfall reached a maximum of five times what it was at landfall (Figure 9). The wind speed in Sumter County exceeded that in the landfall of Hugo in Charleston! NOAA's National Hurricane Center uses an analysis tool that quantifies those chances called the hurricane return period. Track of Hurricane Hugo and location of Sumter County, South Carolina. Barrier islands were swept clean of homes, and new tidal inlets formed in the Hamptons, New York (Figure 16D). And the eye of the hurricane is 30 miles in diameter. Glenn, Jacquelyn R. Overbeck, Mahmoud Hayek, Marie Salgues, Jean-Claude Souche, Klaartje De Weerdt, Sylvain Pioch, Sungyeop Joung, Young-yong Ji, Yoomi Choi, This site uses cookies. (Color for this figure is available in the online version of this paper.). Mark Powell, Hurricane Research Division, National Oceanic and Atmospheric Administration (NOAA), supplied the Hugo radar images used in this paper. Interaction with the land: Landfall typically weakens a hurricane due to friction and reduced energy supply from the ocean. The author's decades-long study of the 1938 hurricane has been aided by a great number of people and organizations. In rushing air brings more heat energy to the system. Damage was reported at many locations in New York and New England (Figure 16). Structural damage included a combination of roof stripping (Figure 14A,B), uprooted trees falling on structures (Figure 14C), and gable-end failure on homes (Figure 14D). This rain caused massive flooding in several towns of Connecticut and Massachusetts (Colton, 1939). How far inland can a hurricane go, you ask? After the 1938 hurricane, the U.S. government sponsored a study of the storm by the Federal Writers Project, Works Progress Administration in the New England States (1938). It made a landfall at Port Allen (Figure 4). Mountains can induce orographic precipitation that can result in massive debris flows (Hurricane Camille in Nelson County, Virginia, 1969). Fred Wolff provided valuable help in a reading of a preliminary manuscript. More recently, Hurricane Harvey in 2017 caused significant flooding in Houston and other areas of Texas. Read more about the conditions that cause hurricanes to rotate. Hurricanes have the potential to travel up to 100 to 200 miles inland. Do not handle electrical equipment and do not use a landline unless it's an emergency. Many trees uprooted or snapped. Central dense overcast (CDO): A thick mass of clouds surrounding the storms center, the CDO is where the heaviest rain and strongest winds occur. But it was Harvey's agonizingly slow meander over or near the Texas . The system strengthens into a tropical depression. Clover (1939) reported extensive tree damage in eastern Long Island. A volume equivalent to 10 to 50 years of sediment was deposited in a few days. Road logStorm damaged areas in central Virginia 1969. They pack all the hazards of the planet's atmosphere: torrential rain, lightning, hail, high speed winds, and tornadoes. Contamination: Flooding can contaminate water supplies with pollutants and pathogens, posing health risks to affected communities. Destruction caused by wind damage in Sumter County, South Carolina. Prepare to be blown away by fascinating facts and gripping tales of these awe-inspiring forces of nature. McCormick (1973) concluded that the coast between Moriches and Shinnecock inlets had receded at an accelerated rate in response to the tidal action at the stabilized inlets. Dry air: Dry air can infiltrate a hurricanes circulation, disrupting its structure and causing it to weaken more rapidly. The staff of the White Mountains National Forest in Laconia, New Hampshire, provided archive photographs of tree damage across New England. 2 days before landfall: Conditions remain the same. Inland hurricanes can have serious consequences for human health and safety, including injuries, fatalities, and mental health impacts. A hurricane's high winds, storm surges, heavy rains and tornadoes all pose a threat to anything in the hurricane's path. Wind channeling is shown in valleys at points 1 and 2. Slower storm motion: Some research suggests that climate change could cause hurricanes to move more slowly, increasing the potential for prolonged rainfall and inland flooding. . The Federal Writer's suggestions were good ones. They analyzed radar patterns to study precipitation as a tropical storm passed over the glacial hills of western Long Island, New York. The quote below is from Williams and Guy (1971): On the night of August 19 a rare combination of circumstances brought about a rapid intensification of the rain fall in the region just east of the Blue Ridge Mountains, especially around Nelson County, Virginia. Thompson (1969) stated that, for Virginia, the amount of rainfall associated with this storm occurs, on average, only once in more than 1000 years. Typically, when a hurricane travels inland, it can no longer collect heat energy from the ocean and quickly reduces to a tropical storm (39 to 73 mph winds) or tropical depression. What were priority items? Turn off gas to prevent leaks from occurring. However, once a hurricane moves inland, it can no longer draw on heat energy from the ocean and weakens rapidly to a tropical storm (39 to 73 mph winds) or tropical depression. It is therefore important to consider the possibility of inland intensification in every future hurricane. Determine escape routes from your home and a nearby place to meet, these places should be measured in tens of miles. (C) House destroyed on Fire Island, New York. And 27 percent of hurricane fatalities are due to inland flooding. As hurricanes move inland, they encounter a variety of obstacles that can weaken their intensity but still cause substantial damage. For example, Tropical Storm Bill (2015) dumped 10 inches of rain in West Texas, leading to flash floods in Austin and San Antonio metro areas. The primary hazard associated with inland hurricanes is flooding, which can have devastating effects on communities, especially those in mountainous regions. This was 2 ft (0.6 m) higher than the water level reached in the 1815 hurricane. From 1970 to 1999, a staggering 60% of flood-related fatalities from tropical storms happened inland, away from the initial landfall. In 2017, Hurricane Harvey dumped the most rain ever recorded during any weather event in the US, with more than 40 inches falling during the storm's four-day slog across Texas and Louisiana. Emergency services: Swift and efficient emergency response efforts can help communities recover more quickly and minimize the long-term impacts of hurricane damage. 100 to 200 miles inland While most residents in Texas, Louisiana, Florida, and other hurricane prone areas understand just how intense hurricane winds and flooding can be, others may not be prepared for the various hazards a hurricane can present. This excessive rainfall softened the soil and made it easy for the strong winds to break and topple trees. Economic stagnation: Inland hurricanes can lead to lasting economic challenges for affected communities, with some areas struggling to rebuild and recover for years. Infrastructure improvements: Enhancing the resilience of critical infrastructure, such as power grids, water systems, and transportation networks, can help minimize service disruptions and expedite recovery efforts. The 1938 hurricane moved north into the low-pressure trough between the two high-pressure ridges. These winds drew moist air from the southeast, and this moisture moved under and joined that of the hurricane to form a very deep layer of moist air. Inland towns in mountainous regions are especially vulnerable to flash flooding. Inland impacts: The remnants of Camille produced torrential rainfall in Virginia, triggering flash floods and landslides that resulted in over 150 fatalities and extensive property damage. Hours: 8:00am-8:00pm ET Monday-Friday 8:00am-5:00pm ET Saturday Closed Sunday. So, how far inland can a hurricane go? The interpretation preferred in this paper is that the orographic effect must have been considerable as Hurricane Camille moved from the low elevations of the Mississippi Valley to flow over the Appalachian and Blue Ridge Mountains. The massive tree uprooting (Figure 14C) tore up water, sewage, and gas lines. Federal Writers Project, Works Progress Administration in the New England States, Satellite and Mesoscale Research Project, University of Chicago. A detailed picture of tree damage in the 1938 Hurricane was given by Wessels (1997). Avoid walking or driving through flood waters. As soon as possible, affected communities must plan with relief agencies so needed work and supplies can be prioritized. Never use charcoal indoors because burning charcoal produces high levels of carbon monoxide that can reach lethal levels in enclosed spaces. A hurricanes destructive power is not limited to coastal regions; its impacts can extend far inland, posing significant risks to communities and infrastructure. If you live on a barrier island with a history of storm surge damage. 100 to 200 miles inland While most residents in Texas, Louisiana, Florida, and other hurricane prone areas understand just how intense hurricane winds and flooding can be, others may not be prepared for the various hazards a hurricane can present. Pierce (1939) explained the role of the temperature difference across the wind field. Inland hurricanes can have significant consequences for agriculture and livestock, leading to crop loss, animal fatalities, and economic hardships for farmers. As seen in the image above, hurricanes in the Pacific ocean form in the waters off western coast of Mexico and often move northwest, further into the ocean. If you live in a mobile home in a coastal area. Some of this hot, dry air evaporates the warm sea surface water in the Atlantic Ocean and forms clouds. Moist air: High humidity in the lower atmosphere contributes to the formation of thunderstorms, which are the building blocks of hurricanes. Coch, N.K., 2020. (Color for this figure is available in the online version of this paper.). And they all begin with calm winds swirling over very calm, warm waters. Inland hurricanes tend to weaken more rapidly than coastal hurricanes due to increased friction and a lack of energy from warm ocean waters. Track and rainfall associated with Hurricane Camille. Natural features caused by a catastrophic storm in Nelson and Amherst Counties, Virginia, 1969. They hope to build jetties in the waters off the coast so as to prevent future washouts. A case study in the effects of coastal engineering structures and beach restoration methods after storms, Westhampton Beach, Long Island, New York. Listen to local officials for updates and instructions on what to do. Mountainous terrain: Mountains can disrupt a hurricanes circulation, causing it to weaken more rapidly. How far inland do hurricanes go in Florida? At the coast, damage from surge and wind was monumental, but the rainfall was only 5 in. Vegetation loss: Strong winds can uproot trees, snap branches, and strip leaves from plants, resulting in property damage, power outages, and ecological impacts. In summary, while hurricanes can travel up to 200 miles inland, their intensity generally decreases as they move farther from the ocean. Introduction to the Risk Maps. Topography: Hilly or mountainous terrain can funnel water into valleys, intensifying flooding and increasing the risk of landslides. Tropical Storm Agnes had a profound effect on America's largest estuary, Chesapeake Bay. What were the meteorological conditions that led to the extraordinary regional damage in the 1938 hurricane? This event is still considered the greatest natural disaster to occur across New England.
