65th Interdepartmental Hurricane Conference Miami, Florida February 28 - March 3, 2011 Hurricane Earl:September 2, 2010 Ocean and Atmospheric Influences on Tropical Cyclone Predictions: Challenges and Recent Progress S E S S Session 2 I The 2010 Tropical Cyclone Season in Review O N 2 The 2010 Atlantic Hurricane Season: Extremely Active but no U.S. Hurricane Landfalls Eric Blake and John L. Beven II ([email protected]) NOAA/NWS/National Hurricane Center The 2010 Atlantic hurricane season was quite active, with 19 named storms, 12 of which became hurricanes and 5 of which reached major hurricane intensity. These totals are well above the long-term normals of about 11 named storms, 6 hurricanes, and 2 major hurricanes. Although the 2010 season was considerably busier than normal, no hurricanes struck the United States. This was the most active season on record in the Atlantic that did not have a U.S. landfalling hurricane, and was also the second year in a row without a hurricane striking the U.S. coastline. A persistent trough along the east coast of the United States steered many of the hurricanes out to sea, while ridging over the central United States kept any hurricanes over the western part of the Caribbean Sea and Gulf of Mexico farther south over Central America and Mexico. The most significant U.S. impacts occurred with Tropical Storm Hermine, which brought hurricane-force wind gusts to south Texas along with extremely heavy rain, six fatalities, and about $240 million dollars of damage. Hurricane Earl was responsible for four deaths along the east coast of the United States due to very large swells, although the center of the hurricane stayed offshore. -

NATIONAL HURRICANE CENTER TROPICAL CYCLONE REPORT HURRICANE ALEX (AL012016) 12 – 15 January 2016 Eric S. Blake National Hurricane Center 13 September 2016 NASA-MODIS VISIBLE IMAGE OF ALEX AT 1530 UTC 14 JANUARY 2016. Alex was a very unusual January hurricane in the northeastern Atlantic Ocean, making landfall on the island of Terceira in the Azores as a 55-kt tropical storm. Hurricane Alex 2 Hurricane Alex 12 – 15 JANUARY 2016 SYNOPTIC HISTORY The precursor disturbance to Alex was first noted over northwestern Cuba on 6 January as a weak low along a stationary front. A strong mid-latitude shortwave trough caused the disturbance to intensify into a well-defined frontal wave near the northwestern Bahamas by 0000 UTC 7 January. The extratropical low then moved northeastward, passing about 75 n mi north of Bermuda late on 8 January. Steered under an anomalous blocking pattern over the east-central Atlantic Ocean, the system turned east-southeastward by 10 January, and strengthened to a hurricane-force extratropical low. The change in track caused the system to move over warmer (and anomalously warm) waters, and moderate convection near the center on that day helped initiate the system’s transition to a tropical cyclone. The low began to weaken as it lost its associated fronts, diving to the south-southeast late on 11 January around a mid-latitude trough over the eastern Atlantic. Significant changes were noted the next day, with the large area of gale-force winds shrinking and becoming more symmetric about the cyclone’s center. Convection also increased near the low, and by 1800 UTC 12 January, frontal boundaries appeared to no longer be associated with the cyclone. -

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. -

Even though convection across this region is less frequent than in many other parts of the country significant thunderstorm events and occasional severe weather does occur. It has been found that a further challenge in convective forecasting across southern California is due to the variety of sub-regions that exist including coastal plains, inland valleys, mountains and deserts, each of which is associated with different weather conditions and sometimes drastically different convective parameters. In this paper four recent thunderstorm case studies were conducted, with each one representative of a different category of seasonal and synoptic patterns that are known to affect southern California. In addition to supporting points made in prior literature there were numerous new and unique findings that were discovered during the scope of this research and these are discussed as they are investigated in their respective case study as applicable. -

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. -
