Six Tropical Storms Make History in Southern Hemisphere on February 25, 2025

On February 25, 2025, six tropical storms were reported in the Southern Hemisphere, a rare event since 1989. Three cyclones were located in the South Pacific and three in the Indian Ocean, driven by favorable weather conditions related to La Niña. Notable storms included Cyclone Honde, Garance, and Hurricane Alfred, each with potential impacts on surrounding regions.

On February 25, 2025, an unusual meteorological event unfolded as six tropical storms occurred simultaneously in the Southern Hemisphere, a phenomenon last witnessed in 1989. Three cyclones were active in the South Pacific Ocean, tied for a record number of simultaneous storms, while three others were present in the Southern Indian Ocean. This remarkable occurrence exemplifies the power of tropical cyclones, which are prevalent from November to April in the Southern Hemisphere.

Among the notable storms, Tropical Cyclone Honde was located off the coast of Mozambique, while Cyclone Garance was near Madagascar. Hurricane Bianca and Hurricane Alfred were identified to the west and northeast of Australia, respectively, and Tropical Cyclones Sera and Rae were situated north of New Zealand. Various atmospheric and oceanic conditions have been conducive to these storms, largely influenced by weak wind shear and elevated sea-surface temperatures, both attributed to the ongoing La Niña phenomenon as described by AccuWeather Expert Jason Nicholls.

The last advisory for Cyclone Rae was issued at 4 p.m. EST on Tuesday, coinciding with the formation of Tropical Cyclone Honde. Cyclone Rae previously inflicted damage in Fiji. Historically, the last occurrence of three simultaneous cyclones in the South Pacific basin was in January 1999 with storms Dani, Olinda, and Pete.

In total, the current tropical season has recorded 22 tropical storms, with Accumulated Cyclone Energy notably exceeding the historical average since February 12. As of Wednesday, the energy measurement reached 166.3, representing 130 percent of the typical value for this date. Two significant storms, Honde and Garance, were highlighted for their potential impact on Madagascar and Reunion Island, respectively.

Cyclone Honde is expected to generate heavy rainfall and strong winds, with forecasts suggesting rainfall up to 48 inches in some regions of southwest Madagascar. Hurricane Garance, predicted to become a hurricane and affect Reunion Island, may produce significant rainfall and wind gusts up to 150 mph, leading to considerable dangers such as coastal flooding.

Hurricane Alfred, having formed in the Coral Sea, is intensifying as it moves toward the south. While it is anticipated to remain east of Australia, its outer bands may still affect parts of southeast Queensland and northeast New South Wales with rain.

In summary, the occurrence of six tropical storms in the Southern Hemisphere on February 25, 2025, marked a significant meteorological event. The alignment of these storms highlights the unique climatic conditions prevalent in the region, particularly influenced by La Niña. As these cyclones continue to develop, their potential impacts on the surrounding regions emphasize the ongoing need for vigilance and preparedness in the face of tropical storms.
