Atlantic Hurricane Season Outlook for June 2020
Atlantic Hurricane Season Outlook for June 2020 ELEVATED U.S. RISKS FROM HURRICANE SEASON 2020 AS VERY BUSY YEAR BEGINS… Outlook Overview ➢ WeatherTiger’s WeatherTiger's June outlook for the 2020 hurricane season is for a 75-80% chance of an above average year, with a 15-20% chance of near-normal and just a 5% chance of below-normal cumulative activity. The median of our forecast is about 180% of average hurricane season activity, or around 19 named storms, nine hurricanes and five major hurricanes. ➢ This is slightly above the consensus of some other recently issued forecasts, likely due to our model's bullishness towards a La Niña developing by late summer or early fall. However, almost all forecast groups project above normal activity. ➢ Overall, while model skill remains limited at this range, convergent lines of evidence from our objective modeling and seasonal analogs support an active season, with the potential for a risky steering current regime in the peak months. Updated Seasonal Outlook for Tropical Cyclone Activity On a lighter note: hurricane season. The devil you know is back. Unlike a pandemic, at least taking down the shutters after a storm won’t make it return. This doesn’t imply that hurricane season 2020 will be reasonable. WeatherTiger’s updated seasonal forecast and a consensus of other guidance favors an abnormally active year. We expect net activity of about three-quarters more than the average season, with 95% odds of more storms than Dr. Birx has scarves. I’ll get into the forecast rationale and what it may mean for Florida, but first, a quick orientation for new readers: I’m Dr. -

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. -

The dissertation of Chongming Wang was reviewed and approved* by the following: Brent Yarnal Professor of Geography Dissertation Advisor Chair of Committee Alexander Klippel Professor of Geography John Kelmelis Professor of of International Affairs Steven Zarit Professor of Human Development and Family Studies Cynthia Brewer Professor of Geography Head of the Department of Geography *Signatures are on file in the Graduate School. ! ABSTRACT Vulnerability of older adults in all stages of a disaster is well recognized by both scholars and practitioners. However, most relevant empirical research to date has focused on disaster recovery and reconstruction, leaving unanswered the “how” and “why” questions surrounding disaster preparedness and response among older people. The older people’s perceptions of natural hazard risks have been even less explored. To address these research gaps, this study uses a case study of older residents of Sarasota County, Florida and applies a qualitative method to understand the perception, preparedness, and evacuation intention of older people at risk from hurricane hazards. The individual in-depth interviews generate several findings. First, while older residents’ knowledge of hurricane threats varied from simple to sophisticated, their perceptions of hurricane risks were predominantly low due to a local myth and hurricane quiescence in recent memory. Second, most older residents took generic actions by preparing extra water, food, and medications, but lacked efforts in more hurricane-specific preparedness due to complacency and lack of awareness, financial capital, and social capital. -
Volusia County Hurricane Irma Flood Warning Program Evaluation Report
Volusia County Hurricane Irma Flood Warning Program Evaluation Report Synopsis Hurricane Irma formed from an African Easterly Wave, more commonly known as tropical waves. It became a tropical storm on August 30 about 420 miles west of the Cabo Verde Islands in the far eastern tropical Atlantic Ocean, and quickly attained hurricane status on August 31st while still in the far eastern Atlantic about 650 miles west of the Cabo Verde Islands. Irma continued to gradually strengthen over the next several days as it tracked generally westward across the tropical Atlantic By the time Hurricane Irma struck Barbuda in the northern Leeward Islands around 2 A.M. on Wednesday, September 6, it was a Category 5 hurricane with 185 mph winds. Five hours later, the eye of Irma moved over St. Martin, still with 185 mph winds, while the northern eyewall pounded Anguilla. That afternoon, Irma cut a path directly through the British Virgin Islands. After the southern eyewall raked St. Thomas, Puerto Rico was largely spared as the center passed about 45 miles north of San Juan. Hurricane conditions did occur on Puerto Rico’s northeastern coast. Still a Category 5, Irma impacted portions of the Turks and Caicos Islands and the southeast Bahamas. From Friday evening September 8th through Saturday afternoon September 9th, Irma moved along the northern coast of Cuba. Interaction with land caused Irma to weaken from a Category 5 to a Category 3 before it began to pull away from the northern coast of Cuba late Saturday afternoon. On Sunday morning, September 10th, Irma strengthened to a Category 4 hurricane as it accelerated toward the Florida Keys. -

Latto, and Robbie Berg National Hurricane Center 1 24 September 2021 VIIRS SATELLITE IMAGE OF HURRICANE IRMA WHEN IT WAS AT ITS PEAK INTENSITY AND MADE LANDFALL ON BARBUDA AT 0535 UTC 6 SEPTEMBER. Irma was a long-lived Cape Verde hurricane that reached category 5 intensity on the Saffir-Simpson Hurricane Wind Scale. The catastrophic hurricane made seven landfalls, four of which occurred as a category 5 hurricane across the northern Caribbean Islands. Irma made landfall as a category 4 hurricane in the Florida Keys and struck southwestern Florida at category 3 intensity. Irma caused widespread devastation across the affected areas and was one of the strongest and costliest hurricanes on record in the Atlantic basin. 1 Original report date 9 March 2018.

For more information on the data depicted in the following infographs please contact: Eric Poole at [email protected],Casey Perkins at [email protected] or Robert Brown at [email protected] Florida Association of Counties ∙ 100 South Monroe Street ∙ Tallahassee, Florida 32301 ∙ www.fl-counties.com Hurricane Evacuation: Lessons Learned and What You Need to Know (continued) Hurricane Irma was the most powerful Atlantic Ocean hurricane in recorded history. By multiple accounts, the storm was also directly responsible for the largest mass exodus in U.S. history, with nearly 7 million people across Florida, Georgia, and South Carolina being asked to evacuate their homes. According to Florida’s Department of Emergency Management (DEM), nearly 6.8 million Floridians evacuated their homes in the lead up to Hurricane Irma, “beating 2005’s Houston-area Hurricane Rita exit by millions.” Media outlets described police going door to door “telling people to leave to avoid life-threatening rains, winds, and flooding,” as well as “large traffic jams on Interstates 95 and 75 and the Florida Turnpike.” Additionally, the Federal Aviation Administration reported that Miami’s traffic controllers handled 11,500 flights on the Thursday before the storm compared to 8,800 one week prior. -
