Abstract This paper aimed at analyzing non-regular sea level variations of meteorological origin under the influence of six major tropical cyclones that affected Cuba, from sea level hourly height series in twelve coastal localities. As a result, it was obtained a characterization of the magnitude and timing of extreme sea level variations under the influence of intense tropical cyclones. Resumen El presente trabajo tuvo como objetivo analizar las variaciones aperiódicas del nivel del mar de origen meteorológico bajo la influencia de seis de los principales ciclones tropicales que han afectado a Cuba, a partir de series de alturas horarias del nivel del mar de doce localidades costeras.

    8786 ReportScience Title and the Storms: the USGS Response to the Hurricanes of 2005 Chapter Five: Landscape5 Changes The hurricanes of 2005 greatly changed the landscape of the Gulf Coast. The following articles document the initial damage assessment from coastal Alabama to Texas; the change of 217 mi2 of coastal Louisiana to water after Katrina and Rita; estuarine damage to barrier islands of the central Gulf Coast, especially Dauphin Island, Ala., and the Chandeleur Islands, La.; erosion of beaches of western Louisiana after Rita; and the damages and loss of floodplain forest of the Pearl River Basin. Aerial Rapid Assessment of Hurricane Damages to Northern Gulf Coastal Habitats By Thomas C. Michot, Christopher J. Wells, and Paul C. Chadwick Hurricane Katrina made landfall in southeast Louisiana on August 29, 2005, and Hurricane Rita made landfall in southwest Louisiana on September 24, 2005. Scientists from the U.S. Geological Survey (USGS) flew aerial surveys to assess damages to natural resources and to lands owned and managed by the U.S. Department of the Interior and other agencies. Flights were made on eight dates from August Introduction 27 through October 4, including one pre-Katrina, three post-Katrina, The USGS National Wetlands and four post-Rita surveys. The Research Center (NWRC) has a geographic area surveyed history of conducting aerial rapid- extended from Galveston, response surveys to assess Tex., to Gulf Shores, hurricane damages along the Ala., and from the Gulf coastal areas of the Gulf of of Mexico shoreline Mexico and Caribbean inland 5–75 mi Sea.

The hurricane progressed to the Arkansas border on August 30th, although feeder bands persisted over Mississippi and Louisiana through the first days of September. By September 5th, a remnant of Hurricane Isaac moved south from the Ohio River Valley back to the Gulf of Mexico. That remnant remained quasi-stationary along the Gulf Coast until September 8th, when a cold front steered the storm northeast, away from Louisiana and Mississippi. The bulk of the heavy rains occurred during August in Hurricane Isaac. Rain totals over 10.0 inches were reported at several locations; Livingston, LA measured 17.87 inches by September 2nd. Areal rainfall totals for August 27th through September 2nd, were over 7.0 inches for southeast and east-central Louisiana.

  • 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.

Bica has been approved for the Department of Computer Science Prof. Leysia Palen (chair) Prof. Kenneth M. Anderson Dr. Julie L. Demuth Prof. Brian C. Keegan Prof. Clayton Lewis Date The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentioned discipline. IRB protocol #19-0077, 19-0109 iii Bica, Melissa J. (Ph.D., Computer Science) The Crisis Informatics of Online Hurricane Risk Communication Thesis directed by Prof. Leysia Palen Social media are increasingly used by both the public and emergency management in disasters. In disasters arising from weather-related hazards such as hurricanes, social media are especially used for communicating about risk in the pre-disaster period when the nature of the hazard is uncertain. This dissertation explores the sociotechnical aspects of hurricane risk communication, especially information diffusion, interpretation, and reaction, as it occurs on social media between members of the public and authoritative weather experts. I first investigate the kinds of hurricane risk information that were shared by authoritative sources on social media during the 2017 Atlantic hurricane season and how different kinds of infor- mation diffuse temporally.

  • Hurricane Isaac Information from NHC Advisory 33B, 8:00 AM CDT Wednesday August 29, 2012 Hurricane Isaac Continues to Lash New Orleans
    HURRICANE TRACKING ADVISORY eVENT™ Hurricane Isaac Information from NHC Advisory 33B, 8:00 AM CDT Wednesday August 29, 2012 Hurricane Isaac continues to lash New Orleans. Isaac is expected to move over Louisiana today and tomorrow and over southern Arkansas early Friday. Weakening is forecast as Isaac moves over land over the next 48 hours, but dangerous storm surge and flood threats from heavy rains are likely to continue through today and tonight. Intensity Measures Position & Heading Landfall Forecast (NHC) Max Sustained Wind 80 mph Position Relative to 40 miles SSW of New Orleans Speed: (cat. 1 hurricane) Land: Now southwest of New Est. Time & Region: Orleans Louisiana Min Central Pressure: 970 mb Coordinates: 29.5 N, 90.5 W T.S. Force Winds: 175 miles Est. Max Sustained Wind 80 mph Bearing/Speed: NW or 310 degrees at 6 mph Hurricane Force Winds: 60 miles Speed: (cat. 1 hurricane) Forecast Summary Within 24 hours, there is a 12% chance Isaac will remain at hurricane strength (74+ mph winds), a 74% chance Isaac will weaken to a tropical storm (39-73 mph winds), and a 14% chance Isaac will further weaken to tropical depression strength or dissipate (winds below 39 mph). The windfield map – based on the CLP5 forecast (below right) – shows that this model has forecast the storm’s peak winds at category 1 hurricane strength (74-95 mph winds). The CLP5 – one of many models used by NOAA – has been statistically identified as the current “best performing” model for Hurricane Isaac by Kinetic Analysis Corp. The combinations of a storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters.
