Mexico has officially entered another hurricane season, facing the looming threat of tropical storms set to test its coastal defenses. With memories of Hurricane Otis, a category five monster that ravaged Guerrero in October 2023, still fresh, the nation remains vigilant as the season approaches. From the Gulf of California to the Yucatan Peninsula, the country’s extensive coastlines provide fertile ground for the formation of these destructive storms, a natural occurrence fueled by warm ocean waters. The hurricane season typically spans from May to November, coinciding with the period when sea temperatures surpass 26ºC.
Despite the inherent unpredictability of tropical cyclones – their formation, intensity, and trajectory often shrouded in uncertainty – experts utilize a range of factors such as sea surface temperatures and wind patterns to forecast the season’s activity. The National Water Commission (Conagua) has issued its predictions for 2024, projecting between 35 and 41 tropical cyclones along Mexico’s coasts. The Pacific side is expected to see 15 to 18 cyclones, a figure roughly in line with historical averages. However, concerns mount over the Atlantic, with forecasts indicating a significant uptick in activity. La Niña, the cold phase of the El Niño-Southern Oscillation (ENSO) cycle, is cited as a key driver behind this increase, with its influence enhancing conditions favoring cyclone formation in the Atlantic basin.
The heightened risk on the Atlantic coast necessitates heightened vigilance, particularly in states bordering the Gulf of Mexico. Tamaulipas, Veracruz, Tabasco, and the Yucatan Peninsula – home to Campeche, Quintana Roo, and Yucatán – are urged to remain on high alert. Christian Domínguez, a meteorologist and researcher at the Institute of Atmospheric and Environmental Sciences at UNAM, underscores the uncertainty inherent in such forecasts. While the number of cyclones may rise, the likelihood of their landfall remains uncertain. Nevertheless, history offers some guidance, with Mexico historically experiencing an average of 5.4 cyclones annually, with certain states bearing the brunt of these storms. Baja California Sur, Quintana Roo, Sinaloa, and Veracruz have historically absorbed over 43% of cyclone impacts.
Reflecting on the tumultuous 2023 season, where eight cyclones made landfall – including the devastating Otis – authorities brace for potentially similar scenarios in 2024. The Saffir-Simpson scale, a widely-used metric for categorizing cyclone intensity, classifies storms into three types: tropical depressions, tropical storms, and hurricanes. While predictions suggest at least five cyclones could impact Mexico this year, the scale offers insights into potential outcomes. Depressions, storms, and hurricanes differ in wind intensity, with hurricanes further classified into five categories based on sustained wind speeds.
As the Pacific season kicked off on May 15, followed by the Atlantic on June 1, communities across Mexico prepare for the onslaught. The season officially concludes on November 30, marking six months of heightened vulnerability. Forecasts for the Pacific anticipate between 15 to 18 cyclones, while the Atlantic braces for a potentially tumultuous 20 to 23 storms. Within these projections, varying degrees of intensity are expected, from tropical storms to major hurricanes, with coastal states urged to remain vigilant throughout.
The hurricane season casts a shadow of uncertainty over Mexico, underscoring the nation’s resilience in the face of nature’s fury. As communities prepare for the worst, authorities and citizens alike remain poised to confront whatever challenges lie ahead in 2024’s turbulent weather landscape.
