Cyclone “Seed” Survival Affects Hurricane Season Intensity

Understanding how seed storms grow into full-blown hurricanes and typhoons could help predict hurricane season intensity in a changing climate.

The Value of Orientation and Mobility in the Preparation, Response, and Recovery of the 2017 Hurricane Season in Puerto Rico

Introduction: The 2017 hurricanes Irma and Maria significantly affected all people in Puerto Rico, including people with visual impairments. This population has historically been underserved; therefore, access to disaster-related services and the overall availability of training in independence skills are inadequate. This study focuses on independence as related to orientation and mobility (O&M) and was part of a larger case study that sought to determine what unique factors affected people with visual impairments during the aforementioned hurricanes and how challenges could potentially improve. Methods: Qualitative exploratory single-case study of the 2017 hurricane season in Puerto Rico. Interviews used language interpreters and were conducted in-person and by telephone between November 2 and December 17, 2018. Referred sampling included 29 people with visual impairments, four relief agencies, an Americans with Disabilities Act (ADA) technical specialist, and seven organizations serving people with visual impairments. Results: The post-Maria travel environment presented many challenges through altered infrastructure. Impact was also felt due to insufficient disaster-related institutional supports and a lack of empowerment for people with visual impairments. Post-disaster life presented mental health challenges; however, the usage of O&M training helped to curb its effects. For study participants, the greater the acquisition and practice of O&M, the greater their well-being. Discussion: Paternalism minimized the acquisition and practice of O&M. Knowledge and practice of O&M were salient in post-disaster life. The use of O&M aided in mental health before, during, and after the hurricanes. Implications for practitioners: Expressions of the importance of O&M skills among participants can be used to encourage future recipients of O&M training. These testimonials can also be used to advocate for more social support and financial assistance for organizations which provide such training.

Reframing Risk in the Wake of COVID-19

Concerns about infectious disease in mega-shelters following hurricanes should be a top priority. The COVID-19 pandemic demonstrated the challenge of implementing standard evacuation and sheltering procedures for hurricanes during an outbreak of a respiratory disease and the lessons learned from the 2020 hurricane season must be applied to future response efforts. In this article, we examine the current risk framing for hurricane preparedness and response utilizing Prospect Theory. We also examine how the COVID-19 pandemic has complicated this traditional framing and offer a new framework for which to provide adequate sheltering following a hurricane, while minimizing the risk of respiratory disease to those seeking shelter. We argue that such a framework is necessary to protect American citizens in future hurricane seasons.

A Hyperactive End to the Atlantic Hurricane Season: October–November 2020

The active 2020 Atlantic hurricane season produced 30 named storms, 14 hurricanes, and 7 major hurricanes (Category 3+ on the Saffir-Simpson Hurricane Wind Scale). Though the season was active overall, the final two months (October–November) raised 2020 into the upper echelon of Atlantic hurricane activity for integrated metrics such as Accumulated Cyclone Energy (ACE). This study focuses on October–November 2020, when 7 named storms, 6 hurricanes, and 5 major hurricanes formed and produced ACE of 74 * 104 kt2. Since 1950, October–November 2020 ranks tied for 3rd for named storms, 1st for hurricanes and major hurricanes, and 2nd for ACE. Six named storms also underwent rapid intensification (≥30 kt intensification in ≤24 hr) in October–November 2020—the most on record.This manuscript includes a climatological analysis of October–November tropical cyclones (TCs) and their primary formation regions. In 2020, anomalously low wind shear in the western Caribbean and Gulf of Mexico, likely driven by a moderate intensity La Niña event and anomalously high sea surface temperatures (SSTs) in the Caribbean provided dynamic and thermodynamic conditions that were much more conducive than normal for late-season TC formation and rapid intensification. This study also highlights October–November 2020 landfalls, including Hurricanes Delta and Zeta in Louisiana and in Mexico and Hurricanes Eta and Iota in Nicaragua. The active late season in the Caribbean would have been anticipated by a statistical model using the July–September-averaged ENSO Longitude Index and Atlantic warm pool SSTs as predictors.

Challenges will delay Caribbean's post-COVID recovery

Significance Jamaicans are to remain in their homes for three consecutive weekends. Although the economies of the English-speaking Caribbean are witnessing a gradual recovery, there are concerns that it will falter in light of a spike in COVID-19 cases in several and a growing anti-vaccination movement. Impacts The remainder of the hurricane season may see further infrastructure damage that will set back recovery. Anti-LGBTQ policies will hinder recovery in the key tourism sector and shave several percentage points off regional GDP. Political resistance to vaccination mandates will mount, undermining efforts to control the pandemic.
