First 2026 Cat 5: Horacio forms in remote Indian Ocean

Tropical Cyclone Horacio became the world’s first Category 5 tropical cyclone of 2026, peaking at 160 mph over warm South Indian Ocean waters; it poses no land threat and is expected to weaken as it moves into cooler waters and higher wind shear, a reminder that climate change may drive a higher share of storms to Category 4–5 strength.
