The sultanate of Oman, located on the southeastern corner of the Arabian Peninsula, regularly receives the impacts of tropical cyclones due to its long coastline along the Arabian Sea. On average, storms strike Oman once every three years, mostly between Masirah Island and Salalah, and usually before the June or after October. From 1943 to 1967, tropical cyclones accounted for about 25% of Salalah's overall rainfall. About once every five years, a storm affects the Dhofar region of southern Oman, and Oman's capital of Muscat about once every ten years in. Between 1890 and 1996, 36 storms struck Oman, although some landfalling storms might be excluded from the historical record due to the lack of population centers. In addition, storm intensities at landfall have only been accurately known since around 1979, and reliable record keeping began around 1970. In 2014, an archaeology team discovered evidence that a major flood affected Ras Al Hadd in eastern Oman, possibly the result of a tsunami or a severe storm.
