NewsNight | The start of what's expected to be a busy hurricane season | Season 2021

The video titled "The Start of What's Expected to Be a Busy Hurricane Season" from PBS NewsHour, hosted by Amna Nawaz, features a detailed discussion on the 2023 Atlantic hurricane season with meteorologist and hurricane specialist Eric Fisher. The conversation delves into the factors contributing to the forecast of an active season, the potential impacts, and the importance of preparedness. Below is an extensive summary of the content covered in the video.

The video begins with Amna Nawaz introducing the topic, highlighting that the Atlantic hurricane season officially started on June 1, 2023, and is expected to be particularly active. She then introduces Eric Fisher, who provides an overview of the current conditions and forecasts for the season.

Eric Fisher starts by explaining that the National Oceanic and Atmospheric Administration (NOAA) and other meteorological agencies have predicted an above-average hurricane season for 2023. He attributes this forecast to several key factors. Firstly, the Atlantic Ocean's sea surface temperatures are unusually warm, which provides more energy for the development and intensification of tropical storms and hurricanes. Secondly, the presence of La Niña conditions in the Pacific Ocean is expected to reduce wind shear over the Atlantic, creating a more favorable environment for hurricane formation.

Fisher elaborates on the significance of warm sea surface temperatures, noting that they have been consistently higher than average for several months. He explains that warmer waters not only fuel the development of storms but can also lead to rapid intensification, where a storm can quickly escalate from a tropical storm to a major hurricane. This phenomenon has been observed more frequently in recent years and poses a significant challenge for forecasting and preparedness.

The discussion then shifts to the role of La Niña. Fisher explains that La Niña is a climate pattern characterized by cooler than average sea surface temperatures in the central and eastern Pacific Ocean. This pattern tends to weaken the jet stream over the Atlantic, reducing wind shear, which is the change in wind speed and direction with height. Lower wind shear allows storms to maintain their structure and intensify more easily. Fisher notes that the current La Niña conditions are expected to persist through the peak of the hurricane season in September and October, further increasing the likelihood of an active season.

Amna Nawaz asks about the potential impacts of an active hurricane season on coastal communities. Fisher responds by emphasizing the importance of preparedness and early action. He explains that coastal areas, particularly those along the Gulf of Mexico and the southeastern United States, are at higher risk of experiencing direct hits from hurricanes. These storms can bring devastating winds, heavy rainfall, and life-threatening storm surges. Fisher stresses that communities need to have robust evacuation plans, emergency shelters, and resources in place to respond effectively to these threats.

The conversation then turns to the broader implications of an active hurricane season. Fisher discusses how hurricanes can have far-reaching effects beyond the immediate coastal areas. He mentions that heavy rainfall associated with hurricanes can lead to inland flooding, which can be just as destructive as the storm itself. Additionally, he notes that the economic impact of hurricanes can be significant, with damages often running into billions of dollars. Fisher emphasizes the need for comprehensive disaster management strategies that address both the immediate and long-term effects of these storms.

Amna Nawaz then asks about the role of climate change in the increasing frequency and intensity of hurricanes. Fisher acknowledges that while it is challenging to attribute any single hurricane to climate change, the overall trend of warmer ocean temperatures and rising sea levels is consistent with what climate models predict. He explains that warmer oceans provide more energy for storms, and higher sea levels exacerbate the impact of storm surges. Fisher also mentions that climate change may be contributing to the observed increase in rapid intensification events, making hurricanes more unpredictable and dangerous.

The discussion concludes with practical advice for individuals and communities on how to prepare for the hurricane season. Fisher recommends staying informed through reliable sources such as the National Hurricane Center and local weather services. He advises having an emergency kit ready, which should include essentials like water, food, medications, and important documents. Fisher also stresses the importance of having a family communication plan and knowing evacuation routes and shelters in advance.

In summary, the video provides a comprehensive overview of the 2023 Atlantic hurricane season, highlighting the factors contributing to the forecast of an active season, the potential impacts on coastal and inland communities, and the importance of preparedness. Eric Fisher's insights underscore the need for vigilance and proactive measures to mitigate the risks associated with hurricanes. As the season progresses, staying informed and prepared will be crucial for minimizing the impact of these powerful storms.
