Part 1-B Cause & Impact of Landfalling Tropical Cyclone
Part 1-b Cause & Impact of Landfalling Tropical Cyclone Rainfall & River Flooding • In addition to high winds & storm surge, all tropical storms can produce torrential rains causing massive flooding & trigger landslides and debris floods • Catastrophic flash flooding may occur as a result of intense rainfall over a relatively short duration. Longer duration storms, say a few days, can be equally devastating. 2 River flooding associated with heavy rainfall from tropical cyclones Flood stages & inundation maps • Rain-triggered flooding is not confined to coastal areas. The reach of a large tropical storm can cause flooding well inland, especially along the estuaries. • Beneficial contributions of tropical cyclones: rainfall for needed water supply in the region; and maintenance of global heat balance 5 Cases of landfalling of catastrophic tropical cyclones • Hurricane Andrew , August 24, 1993- Florida • Hurricane Allison , June 5-9, 2001- Houston and TX and LA coasts • Hurricane Katrina , Aug 29, 2005- New Orleans & LA and TX coasts • Hurricane Mitch , Oct 26- Nov 5, Honduras, Salvador, Nicaragua, and Guatemala • Typhoon Morakot , August 3-10, 2009, Taiwan • Typhoon Ketsana , Sept 23-30, 2009, Manila, Philippine , Vietnam & Cambodia 6 Hurricane Andrew (Aug24,1993) 7 Hurricane Andrew (Aug24,1993) Source: Report on Hurricane Andrew Storm Summary & Impacts on Florida Beaches, by USACE & Florida DNR, May 1993 Pressure zones, wind zones and storm surge contour 9 Surge at landfall & waves height Storm surges Wave Heights 10 Impact of gusts on homes 11 Impacts on beaches of Florida 12 Erosion and accretion of beach profiles 13 Hurricane Allison, June 5-9, 2001 * Hurricane Allison’s swath of rainfall – 25-50 cm or more rainfall in coastal TX & LA for nearly 6 days. -
Observed Hurricane Wind Speed Asymmetries and Relationships to Motion and Environmental Shear
1290 MONTHLY WEATHER REVIEW VOLUME 142 Observed Hurricane Wind Speed Asymmetries and Relationships to Motion and Environmental Shear ERIC W. UHLHORN NOAA/AOML/Hurricane Research Division, Miami, Florida BRADLEY W. KLOTZ Cooperative Institute for Marine and Atmospheric Studies, Rosenstiel School of Marine and Atmospheric Science, University of Miami, Miami, Florida TOMISLAVA VUKICEVIC,PAUL D. REASOR, AND ROBERT F. ROGERS NOAA/AOML/Hurricane Research Division, Miami, Florida (Manuscript received 6 June 2013, in final form 19 November 2013) ABSTRACT Wavenumber-1 wind speed asymmetries in 35 hurricanes are quantified in terms of their amplitude and phase, based on aircraft observations from 128 individual flights between 1998 and 2011. The impacts of motion and 850–200-mb environmental vertical shear are examined separately to estimate the resulting asymmetric structures at the sea surface and standard 700-mb reconnaissance flight level. The surface asymmetry amplitude is on average around 50% smaller than found at flight level, and while the asymmetry amplitude grows in proportion to storm translation speed at the flight level, no significant growth at the surface is observed, contrary to conventional assumption. However, a significant upwind storm-motion- relative phase rotation is found at the surface as translation speed increases, while the flight-level phase remains fairly constant. After removing the estimated impact of storm motion on the asymmetry, a significant residual shear direction-relative asymmetry is found, particularly at the surface, and, on average, is located downshear to the left of shear. Furthermore, the shear-relative phase has a significant downwind rotation as shear magnitude increases, such that the maximum rotates from the downshear to left-of-shear azimuthal location. -

Hurricane Andrew and Insurance: the Enduring Impact of An
HURRICANE ANDREW AND INSURANCE: THE ENDURING IMPACT OF AN HISTORIC STORM AUGUST 2012 Lynne McChristian Florida Representative, Insurance Information Institute (813) 480-6446 [email protected] Florida Office: Insurance Information Institute, 4775 E. Fowler Avenue, Tampa, FL 33617 INTRODUCTION Hurricane Andrew hit Florida on August 24, 1992, and the tumult for the property insurance market there has not ceased in the 20 years since. Andrew was the costliest natural disaster in U.S. history in terms of insurance payouts to people whose homes, vehicles and businesses were damaged by the storm when it struck Florida and Louisiana in 1992. The insurance claims payout totaled $15.5 billion at the time ($25 billion in 2011 dollars). Even today, the storm is the second costliest natural disaster; Hurricane Katrina, which hit in 2005, is the most costly natural disaster. But the cost is only part of Andrew’s legacy. It also revealed that Florida’s vulnerability to hurricanes had been seriously underestimated. That reality was not lost on other coastal states nor on the insurance industry, which reassessed their exposure to catastrophic storm damage in the aftermath of Andrew. The event brought a harsh awakening and forced individuals, insurers, legislators, insurance regulators and state governments to come to grips with the necessity of preparing both financially and physically for unprecedented natural disasters. Many of the insurance market changes that have occurred nationally over the last two decades can be traced to the wakeup call delivered by Hurricane Andrew. These include: . More carefully managed coastal exposure. Larger role of government in insuring coastal risks. -
2014 North Atlantic Hurricane Season Review
2014 North Atlantic Hurricane Season Review WHITEPAPER Executive Summary The 2014 Atlantic hurricane season was a quiet season, closing with eight 2014 marks the named storms, six hurricanes, and two major hurricanes (Category 3 or longest period on stronger). record – nine Forecast groups predicted that the formation of El Niño and below consecutive years average sea surface temperatures (SSTs) in the Atlantic Main – that no major Development Region (MDR)1 through the season would inhibit hurricanes made development in 2014, leading to a below average season. While 2014 landfall over the was indeed quiet, these predictions didn’t materialize. U.S. The scientific community has attributed the low activity in 2014 to a number of oceanic and atmospheric conditions, predominantly anomalously low Atlantic mid-level moisture, anomalously high tropical Atlantic subsidence (sinking air) in the Main Development Region (MDR), and strong wind shear across the Caribbean. Tropical cyclone activity in the North Atlantic basin was also influenced by below average activity in the 2014 West African monsoon season, which suppressed the development of African easterly winds. The year 2014 marks the longest period on record – nine consecutive years since Hurricane Wilma in 2005 – that no major hurricanes made landfall over the U.S., and also the ninth consecutive year that no hurricane made landfall over the coastline of Florida. The U.S. experienced only one landfalling hurricane in 2014, Hurricane Arthur. Arthur made landfall over the Outer Banks of North Carolina as a Category 2 hurricane on July 4, causing minor damage. While Mexico and Central America were impacted by two landfalling storms and the Caribbean by three, Bermuda suffered the most substantial damage due to landfalling storms in 2014.Hurricane Fay and Major Hurricane Gonzalo made landfall on the island within a week of each other, on October 12 and October 18, respectively. -
A Rapid Forecasting and Mapping System of Storm Surge and Coastal Flooding
AUGUST 2020 Y A N G E T A L . 1663 A Rapid Forecasting and Mapping System of Storm Surge and Coastal Flooding KUN YANG,VLADIMIR A. PARAMYGIN, AND Y. PETER SHENG Department of Civil and Coastal Engineering, University of Florida, Gainesville, Florida (Manuscript received 16 July 2019, in final form 2 March 2020) ABSTRACT A prototype of an efficient and accurate rapid forecasting and mapping system (RFMS) of storm surge is presented. Given a storm advisory from the National Hurricane Center, the RFMS can generate a coastal inundation map on a high-resolution grid in 1 min (reference system Intel Core i7–3770K). The foundation of the RFMS is a storm surge database consisting of high-resolution simulations of 490 optimal storms generated by a robust storm surge modeling system, Curvilinear-Grid Hydrodynamics in 3D (CH3D-SSMS). The RFMS uses an efficient quick kriging interpolation scheme to interpolate the surge response from the storm surge database, which considers tens of thousands of combinations of five landfall parameters of storms: central pressure deficit, radius to maximum wind, forward speed, heading direction, and landfall location. The RFMS is applied to southwest Florida using data from Hurricane Charley in 2004 and Hurricane Irma in 2017, and to the Florida Panhandle using data from Hurricane Michael in 2018 and validated with observed high water mark data. The RFMS results agree well with observation and direct simulation of the high-resolution CH3D- SSMS. The RFMS can be used for real-time forecasting during a hurricane or ‘‘what-if’’ scenarios for miti- gation planning and preparedness training, or to produce a probabilistic flood map. -
Investigation and Prediction of Hurricane Eyewall
INVESTIGATION AND PREDICTION OF HURRICANE EYEWALL REPLACEMENT CYCLES By Matthew Sitkowski A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Atmospheric and Oceanic Sciences) at the UNIVERSITY OF WISCONSIN-MADISON 2012 Date of final oral examination: 4/9/12 The dissertation is approved by the following members of the Final Oral Committee: James P. Kossin, Affiliate Professor, Atmospheric and Oceanic Sciences Daniel J. Vimont, Professor, Atmospheric and Oceanic Sciences Steven A. Ackerman, Professor, Atmospheric and Oceanic Sciences Jonathan E. Martin, Professor, Atmospheric and Oceanic Sciences Gregory J. Tripoli, Professor, Atmospheric and Oceanic Sciences i Abstract Flight-level aircraft data and microwave imagery are analyzed to investigate hurricane secondary eyewall formation and eyewall replacement cycles (ERCs). This work is motivated to provide forecasters with new guidance for predicting and better understanding the impacts of ERCs. A Bayesian probabilistic model that determines the likelihood of secondary eyewall formation and a subsequent ERC is developed. The model is based on environmental and geostationary satellite features. A climatology of secondary eyewall formation is developed; a 13% chance of secondary eyewall formation exists when a hurricane is located over water, and is also utilized by the model. The model has been installed at the National Hurricane Center and has skill in forecasting secondary eyewall formation out to 48 h. Aircraft reconnaissance data from 24 ERCs are examined to develop a climatology of flight-level structure and intensity changes associated with ERCs. Three phases are identified based on the behavior of the maximum intensity of the hurricane: intensification, weakening and reintensification. -

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. -
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.
