Cyclone Chapala has already generated sustained winds of 95 knots (175 km/h), according to the Joint Typhoon Warning Centre. It was also producing significant wave heights of more than seven metres. Eric Holthaus, a US meteorologist, estimates the storm will dump as much as eight times the annual rainfall of coastal regions of Yemen and Oman. These regions typically collect just 100-130 millimetres of rain a year.
The port city of Salahah, in Oman, may face a coastal storm surge of as much as 4.5 metres, Mr Holthaus said, adding that it is likely to be heavy deluge and flooding that may pose the bigger threat.
"Tropical cyclones are an extreme rarity near the Arabian Peninsula," Mr Holthaus said. "Since reliable records begin in 1979, there have been only two hurricane-strength storms to make landfall in Oman, and the only storm to hit Yemen topped out with winds at a paltry 35 miles per hour [56 km/h], barely tropical storm strength."
Cyclone Chapala is the latest in a year of extreme weather.
