  • 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.

Shafer2, and Barry Keim3 1Department of Communications, University of Oklahoma 2Oklahoma Climatological Survey, University of Oklahoma 3 Department of Geography and Anthropology, Louisiana State University Experience is what you get when you don’t get what you want. The experience of Hurricane Katrina was not what anyone in New Orleans wanted, yet three years after New Orleans was struck by Hurricane Katrina, the city proved they were ready for the next big one. As the National Hurricane Center forecasts started indicating a possible category 3 or stronger hurricane heading towards Louisiana, the city began preparations for evacuation. Gulf coast residents responded with the largest evacuation in U.S. history. Given the contrast with Katrina, why was the response to Gustav so much better? It is true that government officials learned from Katrina, but Katrina was just one milestone along the way toward making New Orleans safer. This paper examines prior recent experience with hurricanes in Louisiana, events surrounding Hurricane Gustav, and Figure 1.

  • The Great Maritimes Blizzard of February 18-19, 2004
    The Great Maritimes Blizzard of February 18-19, 2004 Chris Fogarty Atlantic Storm Prediction Centre, Dartmouth, Nova Scotia Introduction On 18 February 2004 an intense low pressure system formed well south of Nova Scotia as cold air from eastern North America clashed with the relatively warm waters of the Gulf Stream. The storm moved northeastward passing south of Nova Scotia and over Sable Island. A vast area of heavy snow and high winds swept across Nova Scotia, Prince Edward Island and southeast New Brunswick bringing blizzard conditions and record snowfalls. Widespread amounts of 60 to 90 cm (24 to 36 inches, 2 to 3 feet) were experienced bringing Nova Scotia and Prince Edward Island to a standstill. States of emergency were put into effect across these provinces in order for emergency officials to perform their duties and clean up the mammoth snowfall. It took days for many urban streets and highways to be cleared. 1. The Synoptic Situation A storm track map is shown in Fig. 1 with a time series of minimum sea level pressure in the inset based on analyses at the Maritimes Weather Centre in Halifax, Nova Scotia. The storm formed approximately 200 km southeast of Cape Hatteras, NC at 00 UTC 18 February. It then moved to the northeast at 35-40 km/h, attaining its lowest sea level pressure of 959 mb at 18 UTC 19 February 250 km southeast of Halifax, NS (Fig. 2). Fig. 1. Storm track and time series of minimum sea level pressure. 1 Fig. 2. Sea level pressure analysis of the storm at maximum intensity.

  • Federal Disaster Assistance After Hurricanes Katrina, Rita, Wilma, Gustav, and Ike
    Federal Disaster Assistance After Hurricanes Katrina, Rita, Wilma, Gustav, and Ike Updated February 26, 2019 Congressional Research Service https://crsreports.congress.gov R43139 Federal Disaster Assistance After Hurricanes Katrina, Rita, Wilma, Gustav, and Ike Summary This report provides information on federal financial assistance provided to the Gulf States after major disasters were declared in Alabama, Florida, Louisiana, Mississippi, and Texas in response to the widespread destruction that resulted from Hurricanes Katrina, Rita, and Wilma in 2005 and Hurricanes Gustav and Ike in 2008. Though the storms happened over a decade ago, Congress has remained interested in the types and amounts of federal assistance that were provided to the Gulf Coast for several reasons. This includes how the money has been spent, what resources have been provided to the region, and whether the money has reached the intended people and entities. The financial information is also useful for congressional oversight of the federal programs provided in response to the storms. It gives Congress a general idea of the federal assets that are needed and can be brought to bear when catastrophic disasters take place in the United States. Finally, the financial information from the storms can help frame the congressional debate concerning federal assistance for current and future disasters. The financial information for the 2005 and 2008 Gulf Coast storms is provided in two sections of this report: 1. Table 1 of Section I summarizes disaster assistance supplemental appropriations enacted into public law primarily for the needs associated with the five hurricanes, with the information categorized by federal department and agency; and 2.

  • 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.
