As of now, the current Atlantic hurricane season has seen only six named storms, with most of them being short-lived. The question arises: why is there so little hurricane activity this year?
Phil Klotzbach, a senior research scientist at Colorado State University, pointed out that this year’s subdued hurricane season can be largely attributed to the strong El Niño event currently occurring. El Niño, part of the El Niño-Southern Oscillation (ENSO), impacts ocean temperatures in the central Pacific and atmospheric wind patterns.
When the central Pacific Ocean experiences temperatures 0.5 degrees Celsius above average over a specific period, it signifies an El Niño event. Conversely, temperatures 0.5 degrees Celsius below average indicate a La Niña event. These oscillations have global implications.
At present, there is an El Niño advisory, with models indicating a potentially historic event with anomalies exceeding the previous record set in 1982-1983. The Climate Prediction Center at NOAA forecasts anomalies reaching 2.6 to 2.7 degrees Celsius, signifying a very strong El Niño event.
In the Atlantic, El Niño-induced conditions have hindered hurricane formation. Warmer sea surface temperatures in the eastern Pacific create vertical wind shear in the Atlantic, disrupting the ideal hurricane structure. Consequently, the Atlantic hurricane season has been unusually quiet.
While forecasters anticipated a below-average season, the strong El Niño effect has further subdued hurricane activity. The possibility of significant hurricanes forming in the remaining season is low, although formations in the warm Gulf of Mexico or off the U.S. East Coast remain a possibility.
In contrast, the Pacific Ocean has experienced heightened hurricane activity, with 16 named storms recorded so far. Despite the lack of hurricanes in the Atlantic, short-lived tropical storms in the Gulf of Mexico have impacted coastal areas.
This year’s El Niño is expected to peak in November or December and extend into 2027. The impact on the upcoming hurricane season remains uncertain, as typically, following an El Niño year, the Atlantic experiences warmer conditions but lacks El Niño, making predictions for the next season challenging.
