Cyclone Gonu

Cyclone Gonu (IMD designation: ARB 01, JTWC designation: 02A, also known as Super Cyclonic Storm Gonu) is the strongest tropical cyclone on record in the Arabian Sea, and is also the strongest named cyclone in the northern Indian Ocean. The second named tropical cyclone of the 2007 North Indian Ocean cyclone season, Gonu developed from a persistent area of convection in the eastern Arabian Sea on June 1. With a favorable upper-level environment and warm sea surface temperatures, it rapidly intensified to attain peak winds of 240 km/h (150 mph) on June 3, to the India Meteorological Department. Gonu weakened after encountering dry air and cooler waters, and early on June 6, it made landfall on the eastern-most tip of Oman, becoming the strongest tropical cyclone to hit the Arabian Peninsula. It then turned northward into the Gulf of Oman, and dissipated on June 7 after making landfall in southern Iran.

Intense tropical cyclones like Gonu are extremely rare over the Arabian Sea, since most storms in this area tend to be small and dissipate quickly. The cyclone caused 50 deaths and about $4.2 billion in damage (2007 USD) in Oman, where the cyclone was considered the nation's worst natural disaster. Gonu dropped heavy rainfall near the eastern coastline, reaching up to 610 mm (24 inches), which caused flooding and heavy damage. In Iran, the cyclone caused 28 deaths and $216 million in damage (2007 USD).
