The UN World Meteorological Organization (WMO) has issued a warning for an “above average” hurricane season in the North Atlantic in 2024. Based on data from the US National Oceanic and Atmospheric Administration (NOAA), this would mark the ninth consecutive year of anomalies.
Typically, an average year sees 14 named storms with wind speeds exceeding 65 kilometres (40 miles) per hour. However, this year, 17 to 25 storms are expected, with four to seven of them potentially becoming major hurricanes, characterized by winds of at least 178 kilometres (111 miles) per hour. However, this year, 17 to 25 storms are expected, with four to seven of them potentially becoming major hurricanes, characterized by winds of at least 178 kilometres (111 miles) per hour. The usual average is three major hurricanes per year.
“It takes just one landfalling hurricane to set back years of socio-economic development. For example, Hurricane Maria in 2017 cost Dominica 800 per cent of its Gross Domestic Product,” explained WMO Deputy Secretary-General Ko Barrett.
The forecasted above-average hurricane season, lasting from 1 June to 30 November, is attributed to high ocean heat and the anticipated development of La Niña weather phenomenon, which leads to significant cooling of waters.
WMO tracks hurricanes though its Tropical Cyclone Programme. There have been eight consecutive years of above-average activity, with the last below-normal season occurring in 2015.
Improved early warnings and disaster risk management have significantly reduced hurricane-related fatalities.
However, Small Island Developing States in the Caribbean remain disproportionately affected, according to the WMO Deputy Chief.
The WMO and its partners have prioritized early warning initiatives for small islands under the international Early Warnings For All initiative. They will advocate for more coordinated and targeted investment in early warning systems at the International Conference on Small Island Developing States taking place next week in Antigua and Barbuda.
