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. -

1- Tropical Cyclone Report Hurricane Isabel 6-19 September 2003 Jack Beven and Hugh Cobb National Hurricane Center Revised 1 Ju
Tropical Cyclone Report Hurricane Isabel 6-19 September 2003 Jack Beven and Hugh Cobb National Hurricane Center revised 1 July 2004 Updated 9 September 2014 for U.S. damage Hurricane Isabel was a long-lived Cape Verde hurricane that reached Category 5 status on the Saffir-Simpson Hurricane Scale. It made landfall near Drum Inlet on the Outer Banks of North Carolina as a Category 2 hurricane. Isabel is considered to be one of the most significant tropical cyclones to affect portions of northeastern North Carolina and east-central Virginia since Hurricane Hazel in 1954 and the Chesapeake-Potomac Hurricane of 1933. a. Synoptic History Isabel formed from a tropical wave that moved westward from the coast of Africa on 1 September. Over the next several days, the wave moved slowly westward and gradually became better organized. By 0000 UTC 5 September, there was sufficient organized convection for satellite- based Dvorak intensity estimates to begin. Development continued, and it is estimated that a tropical depression formed at 0000 UTC 6 September, with the depression becoming Tropical Storm Isabel six hours later. The “best track” chart of Isabel is given in Fig. 1, with the wind and pressure histories shown in Figs. 2 and 3, respectively. The best track positions and intensities are listed in Table 1. Isabel turned west-northwestward on 7 September and intensified into a hurricane. Strengthening continued for the next two days while Isabel moved between west-northwest and northwest. Isabel turned westward on 10 September and maintained this motion until 13 September on the south side of the Azores-Bermuda High. -
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. -

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. -

IMELDA (AL112019) 17–19 September 2019
NATIONAL HURRICANE CENTER TROPICAL CYCLONE REPORT TROPICAL STORM IMELDA (AL112019) 17–19 September 2019 Andy Latto and Robbie Berg National Hurricane Center 1 7 February 2020 GOES-16 GEOCOLOR VISIBLE SATELLITE IMAGE OF TROPICAL STORM IMELDA AT 1800 UTC 17 SEPTEMBER 2019. IMAGE COURTESY OF NOAA/NESDIS/STAR. Imelda was a short-lived tropical storm that moved inland over Texas just after it developed. The storm and its remnants meandered inland for a couple of days after landfall and produced historic rainfall totals and devastating flooding over portions of southeastern Texas. 1 Original report dated 29 January. This version corrects landfall pressure in Table 1 and the number of and discussion of fatalities in Texas. Tropical Storm Imelda 2 Tropical Storm Imelda 17–19 SEPTEMBER 2019 SYNOPTIC HISTORY The origins of Imelda can be traced back to a mid- to upper-level trough over the eastern United States. A portion of this trough cut off from the mid-latitudes as a mid- to upper-level low that moved southwestward toward the eastern Gulf of Mexico from 10–12 September and associated shower and thunderstorm activity increased from 12–14 September over the eastern Gulf. A weak surface trough developed on 14 September in the vicinity of the upper low and moved west-northwestward toward the central Gulf. The shower and thunderstorm activity covered a large area and remained disorganized through 15 September as the trough moved from the central to the northwestern Gulf. On 16 September, a broad surface area of low pressure formed as the system approached the Texas coast, and later that night convection became more concentrated near the center of the low. -
