1977 Oman cyclone
The 1977 Oman cyclone was the deadliest tropical cyclone on record to strike Oman. The storm formed off the west coast of India in the Arabian Sea, and curved westward to reach peak winds of 110 km/h (70 mph). The storm struck Masirah Island and later southern Oman on June 13, before dissipating the next day over Saudi Arabia. Producing wind gusts to 230 km/h (140 mph), the storm was the strongest cyclone on record to hit the Arabian Peninsula until Cyclone Gonu hit in 2007. About 95% of Marisah Island was damaged by the strong winds, including much of the military base. The cyclone dropped 430.6 mm (16.95 in) of rainfall over a 24 period on Marisah, which was the highest daily total in the country as of 2003. Overall, the storm killed at least 105 people and left 50,000 homeless.
==Meteorological history==
On June 6, a monsoon depression formed in the Arabian Sea about 500 km (315 mi) south-southwest of Goa, India. It initially paralleled the Indian coastline, becoming a tropical storm on June 9 with a minimum barometric pressure of .〔〔 That day, the Joint Typhoon Warning Center (JTWC) began tracking the system. The storm moved northward, followed by a northwest turn on June 10.〔 It curved toward the west, and the JTWC reported the cyclone as reaching peak 1–minute sustained winds of 110 km/h (70 mph) on June 11.〔 In addition, the India Meteorological Department estimated the system became a severe cyclonic storm, which has sustained winds of at least . On June 12, the storm attained a minimum pressure of while continuing westward.〔
On June 13, the eye of the cyclone passed over Masirah Island for a 40 minute period, producing peak sustained winds of 167 km/h (104 mph) and a minimum pressure of .〔 The JTWC issued the final advisory at 0800 UTC that day.〔 The Oman Department of Meteorology reported the storm as being much stronger than the JTWC, with sustained winds of 165 mph (105 km/h) and gusts to 230 km/h (140 mph). The cyclone was the strongest on record to make landfall on the Arabian Peninsula, until Cyclone Gonu surpassed it in 2007. Shortly after striking Masirah, the storm moved ashore mainland Oman, causing rapid weakening to tropical depression status. The system dissipated on June 14 after crossing into southeastern Saudi Arabia.
