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.

A range of failure wind speeds can be The storm damaged or destroyed many properties, determined by analyzing building damage whereas especially near the coasts. undamaged buildings can provide upper bounds to the Since the hurricane, various agencies have conducted wind speeds.

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. -

Remote Sensing and Statistical Analysis of the Effects of Hurricane María on the Forests of Puerto Rico
Remote sensing and statistical analysis of the effects of hurricane María on the forests of Puerto Rico Yanlei Feng1*, Robinson I. Negrón Juárez2, Jeffrey Q.

This manuscript version is made available under the CC-BY-NC-ND 4.0 license http://creativecommons.org/licenses/by-nc-nd/4.0/ Abstract Widely recognized as one of the worst natural disaster in Puerto Rico’s history, hurricane María made landfall on September 20, 2017 in southeast Puerto Rico as a high-end category 4 hurricane on the Saffir-Simpson scale causing widespread destruction, fatalities and forest disturbance. This study focused on hurricane María’s effect on Puerto Rico’s forests as well as the effect of landform and forest characteristics on observed disturbance patterns. We used Google Earth Engine (GEE) to assess the severity of forest disturbance using a disturbance metric based on Landsat 8 satellite data composites with pre and post-hurricane María. Forest structure, tree phenology characteristics, and landforms were obtained from satellite data products, including digital elevation model and global forest canopy height. Our analyses showed that forest structure, and characteristics such as forest age and forest type affected patterns of forest disturbance. Among forest types, highest disturbance values were found in sierra palm, transitional, and tall cloud forests; seasonal evergreen forests with coconut palm; and mangrove forests. -
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. -
