Jeff Donnelly [[email protected]] Sent: Friday, April 28, 2006 4:55 PM To: [email protected] Subject: Re: Martha's Vineyard and Hurricanes
From: Jeff Donnelly [[email protected]] Sent: Friday, April 28, 2006 4:55 PM To: [email protected] Subject: Re: Martha's Vineyard and Hurricanes Hi Paul... The current hospital location is relatively safe from hurricanes making landfall to the west of Martha's Vineyard. For example storm surge from the 1938 hurricane at that location was between 4 and 6 feet. The location is much more susceptible to nor'easters. You might get 6 feet of surge associated with an intense nor'easter potentially with some large waves on top of that. However, my biggest concern is if an intense hurricane were to slowly pass to the east of the island. This would result in strong north and northeast winds that could pile significant storm surge and waves into Vineyard Haven Harbor. The October 3, 1841 hurricane was just such a storm. One of the key factors is the forward motion of the storm. If the storm track is to the east of the island and it is moving rapidly the speed of forward motion would be subtracted from the rotary winds of the west side of the storm and the duration of strong winds would be less (a couple of hours or less). If the storm moves slowly the duration of onshore hurricane force winds could be more like 6 to 10 hours. In this scenario the hospital might be in peril. You could get between 10 and 15 feet of storm surge in Vineyard Haven Harbor during such an event. From my read of the topographic map it looks like the hospital is between 10 and 20 feet above sea level. -
Guidelines for Storm Preparedness
Eleven Days after Hurricane Carol slammed the Island in August 1964, Hurricane Edna struck on September 11, flooding Edgartown (Vineyard Gazette Archive) Guidelines for Storm Preparedness West Tisbury Climate Action Committee May 2020 May 3-9, 2020: Hurricane Preparedness Week National Weather Service 1 of 11 Storm Preparedness It should come as no surprise that Martha’s Vineyard is vulnerable Nor’easter storms formed over the cold Atlantic between September and April; and hurricanes formed over warm tropical waters from June to November. The absence of hurricanes in recent years have lulled some into thinking they are no longer a serious threat to the Vineyard. The truth is that storms and hurricanes will lash the Vineyard, flooding low-lying portions of our villages, uprooting trees, bringing down power lines, snatching boats from their moorings, and disruption ferry service to the mainland. It is not a question of if; it is a matter of when and with what degree of severity. What is equally sure is that with a modicum of preparedness, your chances of riding out a storm and coping with the inevitable disruptions in the aftermath — the loss of power, telephone and internet connections, and delayed resupplying from the mainland — increase substantially. This manual breaks down emergency preparedness into stages; What you can do immediately without a storm in sight. What you can do when you know a storm is on its way. And, what you can do to make your surroundings as safe as possible when the storm hits. Storm risk varies by the size and path of the storm and by the population of the Vineyard. -
ABSTRACT Title of Document: the EFFECT of HURRICANE SANDY
ABSTRACT Title of Document: THE EFFECT OF HURRICANE SANDY ON NEW JERSEY ATLANTIC COASTAL MARSHES EVALUATED WITH SATELLITE IMAGERY Diana Marie Roman, Master of Science, August 2015 Directed By: Professor, Michael S. Kearney, Environmental Science and Technology Hurricane Sandy, one of several large extratropical hurricanes to impact New Jersey since 1900, produced some of the most extensive coastal destruction within the last fifty years. Though the damage to barrier islands from Sandy was well-documented, the effect of Sandy on the New Jersey coastal marshes has not. The objective of this analysis, based on twenty-three Landsat Thematic Mapper (TM) data sets collected between 1984 and 2011 and Landsat 8 Operational Land Imager (OLI) images collected between 2013 and 2014 was to determine the effect of Hurricane Sandy on the New Jersey Atlantic coastal marshes. Image processing was performed using ENVI image analysis software with the NDX model (Rogers and Kearney, 2004). Results support the conclusion that the marshes were stable between 1984 and 2006, but had decreased in vegetation density coverage since 2007. Hurricane Sandy caused the greatest damage to low-lying marshes located close to where landfall occurred.

Hurricane and Tropical Storm
State of New Jersey 2014 Hazard Mitigation Plan Section 5. Risk Assessment 5.8 Hurricane and Tropical Storm 2014 Plan Update Changes The 2014 Plan Update includes tropical storms, hurricanes and storm surge in this hazard profile. In the 2011 HMP, storm surge was included in the flood hazard. The hazard profile has been significantly enhanced to include a detailed hazard description, location, extent, previous occurrences, probability of future occurrence, severity, warning time and secondary impacts. New and updated data and figures from ONJSC are incorporated. New and updated figures from other federal and state agencies are incorporated. Potential change in climate and its impacts on the flood hazard are discussed. The vulnerability assessment now directly follows the hazard profile. An exposure analysis of the population, general building stock, State-owned and leased buildings, critical facilities and infrastructure was conducted using best available SLOSH and storm surge data. Environmental impacts is a new subsection. 5.8.1 Profile Hazard Description A tropical cyclone is a rotating, organized system of clouds and thunderstorms that originates over tropical or sub-tropical waters and has a closed low-level circulation. Tropical depressions, tropical storms, and hurricanes are all considered tropical cyclones. These storms rotate counterclockwise in the northern hemisphere around the center and are accompanied by heavy rain and strong winds (National Oceanic and Atmospheric Administration [NOAA] 2013a). Almost all tropical storms and hurricanes in the Atlantic basin (which includes the Gulf of Mexico and Caribbean Sea) form between June 1 and November 30 (hurricane season). August and September are peak months for hurricane development. -

More densely populated and developed coastal areas, such as New York City, are the most vulnerable to hurricane-related damages. Before a storm is classified a hurricane, it must pass through four distinct stages: tropical disturbance, tropical depression, tropical storm and lastly a hurricane.

Richmond, VA Hurricanes
Hurricanes Influencing the Richmond Area Why should residents of the Middle Atlantic states be concerned about hurricanes during the coming hurricane season, which officially begins on June 1 and ends November 30? After all, the big ones don't seem to affect the region anymore. Consider the following: The last Category 2 hurricane to make landfall along the U.S. East Coast, north of Florida, was Isabel in 2003. The last Category 3 was Fran in 1996, and the last Category 4 was Hugo in 1989. Meanwhile, ten Category 2 or stronger storms have made landfall along the Gulf Coast between 2004 and 2008. Hurricane history suggests that the Mid-Atlantic's seeming immunity will change as soon as 2009. Hurricane Alley shifts. Past active hurricane cycles, typically lasting 25 to 30 years, have brought many destructive storms to the region, particularly to shore areas. Never before have so many people and so much property been at risk. Extensive coastal development and a rising sea make for increased vulnerability. A storm like the Great Atlantic Hurricane of 1944, a powerful Category 3, would savage shorelines from North Carolina to New England. History suggests that such an event is due. Hurricane Hazel in 1954 came ashore in North Carolina as a Category 4 to directly slam the Mid-Atlantic region. It swirled hurricane-force winds along an interior track of 700 miles, through the Northeast and into Canada. More than 100 people died. Hazel-type wind events occur about every 50 years. Areas north of Florida are particularly susceptible to wind damage. -

Hurricane & Tropical Storm
5.8 HURRICANE & TROPICAL STORM SECTION 5.8 HURRICANE AND TROPICAL STORM 5.8.1 HAZARD DESCRIPTION A tropical cyclone is a rotating, organized system of clouds and thunderstorms that originates over tropical or sub-tropical waters and has a closed low-level circulation. Tropical depressions, tropical storms, and hurricanes are all considered tropical cyclones. These storms rotate counterclockwise in the northern hemisphere around the center and are accompanied by heavy rain and strong winds (NOAA, 2013). Almost all tropical storms and hurricanes in the Atlantic basin (which includes the Gulf of Mexico and Caribbean Sea) form between June 1 and November 30 (hurricane season). August and September are peak months for hurricane development. The average wind speeds for tropical storms and hurricanes are listed below: . A tropical depression has a maximum sustained wind speeds of 38 miles per hour (mph) or less . A tropical storm has maximum sustained wind speeds of 39 to 73 mph . A hurricane has maximum sustained wind speeds of 74 mph or higher. In the western North Pacific, hurricanes are called typhoons; similar storms in the Indian Ocean and South Pacific Ocean are called cyclones. A major hurricane has maximum sustained wind speeds of 111 mph or higher (NOAA, 2013). Over a two-year period, the United States coastline is struck by an average of three hurricanes, one of which is classified as a major hurricane. Hurricanes, tropical storms, and tropical depressions may pose a threat to life and property. These storms bring heavy rain, storm surge and flooding (NOAA, 2013). The cooler waters off the coast of New Jersey can serve to diminish the energy of storms that have traveled up the eastern seaboard. -
