Up to 14½ inches (368mm) fell in Al Khaburah, which is just to the west of where the storm came ashore. The city of about 40,000 people averages between three and four inches (75 to 100mm) of rain per year.
Shaheen was the first tropical cyclone to make landfall along Oman’s northern coast since 1890 and only the third on record. None have been observed in the era of weather satellites (since the 1960s) or during the month of October. According to meteorologists Bob Henson and Jeff Masters, writing for Yale Climate Connections, it struck farther west in Oman than any previous tropical cyclone.
Henson and Masters wrote that Shaheen fed off the very warm waters of the Gulf of Oman, which were several degrees warmer than normal. Ocean temperatures have been rising worldwide because of human-caused climate change.
