Tropical Cyclone Horacio Intensifies into Category 5 Storm in South Indian Ocean

Tropical Cyclone Horacio has swiftly intensified into the world’s first Category 5 storm of 2026, the highest possible classification for tropical cyclones. The storm has reportedly surged from 65 mph to around 160 mph in the South Indian Ocean in just 24 hours, equivalent to roughly 260 kilometres per hour. Horacio’s wind speed and intensity place it in the most powerful category on the Saffir-Simpson scale. Here’s what to know about India’s vulnerability to storms of this intensity, and more. Horacio is developed over the remote waters of the South Indian Ocean. Such storms are relatively rare worldwide. They form only under specific atmospheric and oceanic conditions. Just like all tropical cyclones, it begins as a low-pressure system over the ocean. What makes Horacio significant is the rapid pace of its intensification. Horacio strengthened quickly under favourable weather conditions, with warm ocean waters fuelling its growth into a major storm. It now ranks as the strongest storm globally this year, according toMoneycontrol. On the widely used Saffir-Simpson Hurricane Wind Scale, a Category 5 cyclone is the most intense and highest type of cyclonic storm. Its sustained wind speeds exceed 250 kilometres per hour,News18reported. Wind at this speed generates extreme rainfall and towering ocean waves. It also has catastrophic, destructive potential. It can tear roofs off buildings, uproot large trees, cripple power infrastructure, and cause extensive damage to coastal communities. Intense rainfall can also lead to flash floods and landslides far beyond the immediate area of the zone. At present, there is no such indication, and Horacio poses no direct threat to India. It is mainly due to its location, which is far from the Indian coastline. It is located in the southern Indian Ocean, far from the two main cyclone-generating regions that typically affect India, the Bay of Bengal and the Arabian Sea.

Prevailing wind patterns and temperature contrasts act as natural barriers, keeping them within their own ocean basins. Now this makes it highly unlikely that Horacio will track toward Indian waters. At present, there are no forecasts indicating any indirect weather impact on India’s coastal states, according to media reports. India is keeping a close eye on it, as it’s one of the world’s mostcyclone-vulnerable countries. The nation has witnessed several extremely powerful cyclones in recent years. In 2019,Cyclone Faniintensified to a Category 5–equivalent storm, causing widespread destruction in Odisha. Other states, such as Gujarat, are also exposed to storms that form in the Arabian Sea. Meteorologists are closely studying Horacio’s rapid intensification. They refer to this as “rapid intensification," a process. Scientists are studying sea surface temperatures and wind patterns, with ocean waters recorded at around 27 to 28 degrees Celsius. Such warm conditions supply the energy needed for cyclones to intensify. Satellite data is also used to monitor wind speeds and the storm’s movement.

He is expected to criticize the Supreme Court's ruling against his tariffs and highlight foreign policy moves, including actions in Iran and Venezuela. Several Democrats plan to boycott the speech, attending a protest rally instead, as Trump faces skepticism over his claims of economic success. Get the latest stories delivered straight to your inbox.
