  • 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.

  • Radar and Rain Gauge Analysis of the Extreme Rainfall During Hurricane Danny’S (1997) Landfall
    MAY 2007 M E D L I N E T A L . 1869 Radar and Rain Gauge Analysis of the Extreme Rainfall during Hurricane Danny’s (1997) Landfall JEFFREY M. MEDLIN National Weather Service Forecast Office, Mobile, Alabama SYTSKE K. KIMBALL AND KEITH G. BLACKWELL Department of Earth Sciences, University of South Alabama, Mobile, Alabama (Manuscript received 27 October 2005, in final form 20 June 2006) ABSTRACT As a minimal hurricane, Danny moved over Mobile Bay around 0900 UTC 19 July 1997 and became stationary by midmorning, while situated within a synoptic col. Danny then evolved into an asymmetric storm with an intensely convective rainband that produced torrential rainfall through 1200 UTC 20 July 1997. Danny’s center remained Ͻ100 km from the National Weather Service (NWS) Weather Surveillance Radar-1988 Doppler (WSR-88D) in Mobile, Alabama, for over 48 h, allowing long-term surveillance of the storm’s inner core. This event marked the first time the tropical Z–R relationship was employed on an operational WSR-88D system during tropical cyclone landfall. A radar-estimated maximum rainfall accu- mulation of 1097 mm (43.2 in.) was analyzed over southwestern Mobile Bay. A NWS cooperative rain gauge located on Dauphin Island, Alabama, measured 896 mm (35.28 in.). An adjacent standard rain gauge measured the highest rainfall amount of 932 mm (36.71 in.). This paper investigates the spatial and temporal distribution and potential magnitude of Danny’s torrential rainfall episode over coastal Alabama. It is shown that both gauges and radar seriously underestimated event rainfall. An estimate is given for what could have been the true event rainfall amount.

  • A Classification Scheme for Landfalling Tropical Cyclones
    A CLASSIFICATION SCHEME FOR LANDFALLING TROPICAL CYCLONES BASED ON PRECIPITATION VARIABLES DERIVED FROM GIS AND GROUND RADAR ANALYSIS by IAN J. COMSTOCK JASON C. SENKBEIL, COMMITTEE CHAIR DAVID M. BROMMER JOE WEBER P. GRADY DIXON A THESIS Submitted in partial fulfillment of the requirements for the degree Master of Science in the Department of Geography in the graduate school of The University of Alabama TUSCALOOSA, ALABAMA 2011 Copyright Ian J. Comstock 2011 ALL RIGHTS RESERVED ABSTRACT Landfalling tropical cyclones present a multitude of hazards that threaten life and property to coastal and inland communities. These hazards are most commonly categorized by the Saffir-Simpson Hurricane Potential Disaster Scale. Currently, there is not a system or scale that categorizes tropical cyclones by precipitation and flooding, which is the primary cause of fatalities and property damage from landfalling tropical cyclones. This research compiles ground based radar data (Nexrad Level-III) in the U.S. and analyzes tropical cyclone precipitation data in a GIS platform. Twenty-six landfalling tropical cyclones from 1995 to 2008 are included in this research where they were classified using Cluster Analysis. Precipitation and storm variables used in classification include: rain shield area, convective precipitation area, rain shield decay, and storm forward speed. Results indicate six distinct groups of tropical cyclones based on these variables. ii ACKNOWLEDGEMENTS I would like to thank the faculty members I have been working with over the last year and a half on this project. I was able to present different aspects of this thesis at various conferences and for this I would like to thank Jason Senkbeil for keeping me ambitious and for his patience through the many hours spent deliberating over the enormous amounts of data generated from this research.

RAPPAPORT Tropical Prediction Center, National Hurricane Center, NOAA/NWS, Miami, Florida (Manuscript received 12 June 1998, in ®nal form 5 October 1998) ABSTRACT The 1997 Atlantic hurricane season is summarized and the year's tropical storms, hurricanes, and one sub- tropical storm are described. The tropical cyclones were relatively few in number, short lived, and weak compared to long-term climatology. Most systems originated outside the deep Tropics. Hurricane Danny was the only system to make landfall. It produced rainfall totals to near 1 m in southern Alabama and is blamed for ®ve deaths. Hurricane Erika was responsible for the season's two other fatalities, in the coastal waters of Puerto Rico. 1.

  • Doppler-Observed Eyewall Replacement, Vortex Contraction/Intensi®Cation, and Low-Level Wind Maxima
    4002 MONTHLY WEATHER REVIEW VOLUME 128 The Evolution of Hurricane Danny (1997) at Landfall: Doppler-Observed Eyewall Replacement, Vortex Contraction/Intensi®cation, and Low-Level Wind Maxima KEITH G. BLACKWELL Department of Geology, Geography, and Meteorology, University of South Alabama, Mobile, Alabama (Manuscript received 26 April 1999, in ®nal form 9 March 2000) ABSTRACT Danny made landfall as a minimal hurricane on the Alabama coast on 19 July 1997 after drifting over Mobile Bay for over 10 h. Danny's unusually close proximity to the Doppler radar (WSR-88D) in Mobile provided an unprecedented view of the storm's complex and dramatic evolution during a prolonged landfall event over a 1-day period. Base re¯ectivity and velocity products were combined with aircraft reconnaissance information to detail the formation of concentric eyewalls and complete evolution of an eyewall replacement cycle. This highly symmetric hurricane then underwent a rapid asymmetric transition in Mobile Bay during which a small eyewall mesovortex developed adjacent to intense convection in the western eyewall. Radar-estimated rainfall increased dramatically during the asymmetric phase. Rates exceeded 100 mm h21 for nine consecutive hours west of the center while precipitation nearly vanished to the east. Changes in the distribution of precipitation corresponded with changes in the low-level wind velocity structure. A 25-h temporal composite of WSR-88D base velocities displayed axisymmetric intensi®cation and contraction of Danny's core during the eyewall replacement cycle. Later, the asymmetric phase was dominated by further contraction and intensi®cation on the west side only. In the western eyewall, a persistent boundary layer wind maximum evolved and contracted to a radius of only 10±13 km from the center.

    MAY 1987 US Army Corps of Engineers New Orleans District 4r----------------- . / TC 423 .N46 1987 EC FOREWORD The coastline of Louisiana is highly susceptible to hurricane strength storms which enter the area from the Gulf of Mexico. During a normal hurricane season, which extends from June 1st to November 30th, the Louisiana coast will experience on an average about one hurricane per year. However, during the 1985 hurricane season, Louisiana was struck by three hurricanes: DANNY in August, ELENA in September, and JUAN in October. While the first hurricane (DANNY) was not intense, the second (ELENA) and third (JUAN) were stronger and, more importantly, erratic and dilatory in making landfall. Waves generated by JUAN battered the Louisiana coast for at least 3 days. It is difficult to relate the severity of these events to a design storm, but it appears reasonable to conclude that the combined impact of the season's storms well exceeded that which would be associated with the passage of a design hurricane, which would occur once in 100 years. i TABLE OF CONTENTS PAGE FOREWARD ••.•••..•••••.. e.s ..................................... i STORNS DURING THE 1985 HURRICANE SEASON. • . v INTRODUCTION ....... e •••••• * •••• "'- .............................. vii HURRICANE JUAN NARRATIVE . .........•.•. o • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • 1 METEOROLOGICAL & HYDROLOGICAL DATA .......................... 3 HIGHLIGHTS OF STORM DAMAGES ...............•................. 16 THE INCIDENT PERIOD - Daily log of events . • . 18 DAMAGES & EMERGENCY ACTIVITIES ...........•.................. 28 CORPS ASSISTANCE TO FEMA (Recovery efforts under PL93-288) ... 54 HURRICANE DANNY DESCRIPTION & DAMAGES...... • . 60 HURRICANE ELENA DESCRIPTION & DANAGES....... 66 PHOT'O SEC'TION .........

    OCTOBER 2000 ANNUAL SUMMARY 3695 ANNUAL SUMMARY Atlantic Tropical Systems of 1996 and 1997: Years of Contrasts LIXION A. AVILA,RICHARD J. PASCH, AND JIANN-GWO JIING NOAA/NWS/Tropical Prediction Center/National Hurricane Center, Miami, Florida (Manuscript received 13 August 1999, in ®nal form 14 January 2000) ABSTRACT A total of 62 and 63 tropical waves were counted in the Atlantic from May to November during 1996 and 1997, respectively. These waves led to the formation of 12 of the 13 total number of tropical cyclones in 1996 and only 3 of 7 tropical cyclones in 1997. All of the tropical depressions became tropical storms in 1996 and only one failed to become a named storm in 1997. On average, 62% of the Atlantic tropical depressions develop from tropical waves. These waves contributed to the formation of 92% of the eastern Paci®c tropical cyclones in 1996 and 83% in 1997. Tropical waves and their environment during the 1996 and 1997 seasons are discussed. 1.
