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. -

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. -

Service Assessment Hurricane Isabel September 18-19, 2003 U.S. DEPARTMENT OF COMMERCE National Oceanic and Atmospheric Administration National Weather Service Silver Spring, Maryland Cover: Moderate Resolution Imaging Spectroradiometer (MODIS) Rapid Response Team imagery, NASA Goddard Space Flight Center, 1555 UTC September 18, 2003. Service Assessment Hurricane Isabel September 18-19, 2003 May 2004 U.S. DEPARTMENT OF COMMERCE Donald L. Evans, Secretary National Oceanic and Atmospheric Administration Vice Admiral Conrad C. Lautenbacher, Jr., U.S. Navy (retired), Administrator National Weather Service Brigadier General David L. Johnson, U.S. Air Force (Retired), Assistant Administrator Preface The hurricane is one of the most potentially devastating natural forces. The potential for disaster increases as more people move to coastlines and barrier islands. To meet the mission of the National Oceanic and Atmospheric Administration’s (NOAA) National Weather Service (NWS) - provide weather, hydrologic, and climatic forecasts and warnings for the protection of life and property, enhancement of the national economy, and provide a national weather information database - the NWS has implemented an aggressive hurricane preparedness program. Hurricane Isabel made landfall in eastern North Carolina around midday Thursday, September 18, 2003, as a Category 2 hurricane on the Saffir-Simpson Hurricane Scale (Appendix A). Although damage estimates are still being tabulated as of this writing, Isabel is considered one of the most significant tropical cyclones to affect northeast North Carolina, east central Virginia, and the Chesapeake and Potomac regions since Hurricane Hazel in 1954 and the Chesapeake-Potomac Hurricane of 1933. Hurricane Isabel will be remembered not for its intensity, but for its size and the impact it had on the residents of one of the most populated regions of the United States. -

ANNUAL SUMMARY Atlantic Hurricane Season of 2005
MARCH 2008 ANNUAL SUMMARY 1109 ANNUAL SUMMARY Atlantic Hurricane Season of 2005 JOHN L. BEVEN II, LIXION A. AVILA,ERIC S. BLAKE,DANIEL P. BROWN,JAMES L. FRANKLIN, RICHARD D. KNABB,RICHARD J. PASCH,JAMIE R. RHOME, AND STACY R. STEWART Tropical Prediction Center, NOAA/NWS/National Hurricane Center, Miami, Florida (Manuscript received 2 November 2006, in final form 30 April 2007) ABSTRACT The 2005 Atlantic hurricane season was the most active of record. Twenty-eight storms occurred, includ- ing 27 tropical storms and one subtropical storm. Fifteen of the storms became hurricanes, and seven of these became major hurricanes. Additionally, there were two tropical depressions and one subtropical depression. Numerous records for single-season activity were set, including most storms, most hurricanes, and highest accumulated cyclone energy index. Five hurricanes and two tropical storms made landfall in the United States, including four major hurricanes. Eight other cyclones made landfall elsewhere in the basin, and five systems that did not make landfall nonetheless impacted land areas. The 2005 storms directly caused nearly 1700 deaths. This includes approximately 1500 in the United States from Hurricane Katrina— the deadliest U.S. hurricane since 1928. The storms also caused well over $100 billion in damages in the United States alone, making 2005 the costliest hurricane season of record. 1. Introduction intervals for all tropical and subtropical cyclones with intensities of 34 kt or greater; Bell et al. 2000), the 2005 By almost all standards of measure, the 2005 Atlantic season had a record value of about 256% of the long- hurricane season was the most active of record. -

Appendix 8 Hazard Analysis
Appendix 8 Hazard Analysis Introduction This appendix includes several components. First is an overall discussion of the Hazard Analysis modeling effort, describing the surge (ADCIRC) and wave (WAM, STWAVE) modeling. That first section is followed by a subsidiary section labeled Appendix 8-1 that defines the many acronyms used in the modeling discussion. This is followed by a major section labeled Appendix 8-2 consisting of the Whitepaper of Donald T. Resio, ERDC-CHL, which forms the basis of the storm statistics and JPM methods discussed in the main body of the report. Owing to its prominence in the discussion, it has, for convenience, been referred to as R2007. Note that R2007, itself, includes several appendices; these are identified as Appendices A-G within Appendix 8-2. Finally, a discussion of the rainfall model is included here as Appendix 8-3. Hazard Analysis The hazard analysis required for the risk assessment was based upon the hurricane modeling conducted by a team of Corps of Engineers, FEMA, NOAA, private sector and academic researchers working toward the definition of a new system for estimating hurricane surges and waves. Following is a discussion of the processes used by this team and the steps taken by the risk team to incorporate the results into the risk analysis. The hurricane hazard definition required as input to the risk analysis involved several steps: 1. Selection of the methodology to be used for estimating surges and waves 2. Determination of hurricane probabilities 3. Production of the ADCIRC grid models for the different HPS configurations. 4. Production of the computer system for development of the large number of hydrographs required by the risk model. -

Hydrologic Response of Forested Lands During The
HYDROLOGICAND WATER-QUALITYRESPONSE OF FORESTED AND AGRICULTURALLANDS DURING THE 1999 EXTREME WEATHERCONDITIONS IN EASTERN NORTH CAROLINA J. D. Shelby, G. M. Chescheir, R. W. Skaggs, D. M. Amatya ABSTRACT. This study evaluated hydrologic and water-quality data collected on a coastal-plain research watershed during a series of hurricanes and tropical storms that hit coastal North Carolina in 1999, including hurricanes Dennis, Floyd, and Irene. DUring September and October 1999, the research watershed received approximately 555 mm of rainfall associated with hurricanes. This was the wettest such period in a 49-year historical weather record (1951 -1999). Prior to the hurricanes, the watershed experienced a dry late wintel; spring, and summer (565 cm for Feb.-Aug.). Tlzis was the third driest such period in the 49-year record Maximum daily flow rates measured across the research watershed were greater during hurricane Floyd than for any other time in a four-year (1996-1999) study of the watershed. Daily flows observed for an agricultural subwatershed were generally greater than for a forested subwatershed throughout the study, and during the hurricanes of 1999. Daily nutrient loads measured across the research watershed were greater during hurricane Floyd than for any other time in the study. In general, the two-month period of hurricanes produced total nitrogen and total phosphorus loads nearly equal to average loads for an entire year: Total annual nitrogen export from an agricultural subwatershed was 18 kghin 1999, with 11 kgh(61 %) lost during September and October: Total annual nitrogen export from a forested subwatershed was 15 kghin 1999, with 10 kgha (67%)lost during September and October: The nitrogen export observed in the forested subwatershed was high compared to other forested areas, likely due to the highly permeable organic soils in the watershed.
