Wind Speed-Damage Correlation in Hurricane Katrina
JP 1.36 WIND SPEED-DAMAGE CORRELATION IN HURRICANE KATRINA Timothy P. Marshall* Haag Engineering Co. Dallas, Texas 1. INTRODUCTION According to Knabb et al. (2006), Hurricane Katrina Mehta et al. (1983) and Kareem (1984) utilized the was the costliest hurricane disaster in the United States to concept of wind speed-damage correlation after date. The hurricane caused widespread devastation from Hurricanes Frederic and Alicia, respectively.

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. -

IsaacIsaac MonroeMonroe ClineCline USWS meteorologist Isaac Monroe Cline pioneered the study of tropical cyclones and hurricanes in the early 20th Century, by recording barometric pressures, storm surges, and wind velocities. •• Cline charted barometric gradients (right) and tracked the eyes of hurricanes as they approached landfall. This shows the event of Sept 29, 1915 hitting the New Orleans area. • Storm or tidal surges are caused by lifting of the oceanic surface by abnormal low atmospheric pressure beneath the eye of a hurricane. The faster the winds, the lower the pressure; and the greater the storm surge. At its peak, Hurricane Katrina caused a surge 53 feet high under its eye as it approached the Louisiana coast, triggering a storm surge advisory of 18 to 28 feet in New Orleans (image from USA Today). StormStorm SurgeSurge •• The surge effect is minimal in the open ocean, because the water falls back on itself •• As the storm makes landfall, water is lifted onto the continent, locally elevating the sea level, much like a tsunami, but with much higher winds Images from USA Today •• Cline showed that it was then northeast quadrant of a cyclonic event that produced the greatest storm surge, in accordance with the drop in barometric pressure. -

RE-ANALYSIS of 1969'S HURRICANE CAMILLE COMPLETED Catastrophic Hurricane Now Ranks As Second Strongest on Record
RE-ANALYSIS OF 1969’s HURRICANE CAMILLE COMPLETED Catastrophic hurricane now ranks as second strongest on record A re-analysis of the database for Hurricane Camille, an extremely intense hurricane that devastated the U.S. Gulf Coast on the night of August 17, 1969, has been completed. Based upon this reassessment, Hurricane Camille is indicated at landfall on the Mississippi coast to have been a Category 5 on the Saffir-Simpson Hurricane Wind Scale with peak sustained winds of 175 mph and a central pressure of 900 mb. This is the same category as analyzed originally, but the peak sustained winds were reduced from 190 mph and the central pressure lowered from 909 mb. Camille is also reanalyzed to have undergone genesis as a tropical cyclone 18 hours earlier than first indicated on August 14, 1969. When comparing Camille with the two other known Category 5 hurricanes that have struck the continental United States since 1900, Camille (900 mb and 175 mph) ranks between the 1935 Labor Day hurricane (892 mb and 185 mph) and 1992’s Andrew (922 mb and 165 mph) as the strongest hurricanes on record at landfall. Hurricane Camille on the afternoon of August 17, 1969, from the ESSA-9 polar orbiting satellite. Revisions to the Camille’s database were accomplished by obtaining the original observations collected – mainly by ships, weather stations, coastal radars, Navy/Air Force/Environmental Science Services Administration (ESSA) Hurricane Hunter aircraft reconnaissance planes, ESSA/NASA satellite imagery – and analyzing Camille based upon our understanding of hurricanes today. (The agency ESSA is now the National Oceanic and Atmospheric Administration - NOAA.) Margie Kieper, Jack Beven, Hugh Willoughby, Chris Landsea, and the NHC Best Track Change Committee all made substantial contributions toward the reanalysis of this devastating hurricane. -

Entire neighborhoods were flooded. Families lost their homes. Businesses were destroyed. Infrastructure was torn apart. After all the damage was done, it was clear that the region faced a long, hard road back. That is why President Obama pledged to work with local partners every step of the way to help affected communities rebuild and recover. In recent years, the Federal Government has made great strides in preparing for and responding to natural disasters. In the case of Sandy, we had vast resources in place before the storm struck, allowing us to quickly organize a massive, multi-agency, multi-state, coordinated response. To ensure a full recovery, the President joined with State and local leaders to fight for a $50 billion relief package. The Task Force and the entire Obama Administration has worked tirelessly to ensure that these funds are getting to those who need them most – and quickly. -
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. -
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. -
Hurricane Andrew in Florida: Dynamics of a Disaster ^
Hurricane Andrew in Florida: Dynamics of a Disaster ^ H. E. Willoughby and P. G. Black Hurricane Research Division, AOML/NOAA, Miami, Florida ABSTRACT Four meteorological factors aggravated the devastation when Hurricane Andrew struck South Florida: completed replacement of the original eyewall by an outer, concentric eyewall while Andrew was still at sea; storm translation so fast that the eye crossed the populated coastline before the influence of land could weaken it appreciably; extreme wind speed, 82 m s_1 winds measured by aircraft flying at 2.5 km; and formation of an intense, but nontornadic, convective vortex in the eyewall at the time of landfall. Although Andrew weakened for 12 h during the eyewall replacement, it contained vigorous convection and was reintensifying rapidly as it passed onshore. The Gulf Stream just offshore was warm enough to support a sea level pressure 20-30 hPa lower than the 922 hPa attained, but Andrew hit land before it could reach this potential. The difficult-to-predict mesoscale and vortex-scale phenomena determined the course of events on that windy morning, not a long-term trend toward worse hurricanes. 1.
