While Keila was offshore and still in its developmental stages, it brought winds of 41 km/h (25 mph) to Salalah International Airport, and at the time of landfall, the station reported slightly stronger winds of 43 km/h (26 mph). However, the storm's most severe effects were related to the heavy rainfall it produced over Oman, which peaked at just over in the mountains near Salalah. In southern Oman, Keila dropped of rainfall at Salalah, the equivalent of a year's worth of precipitation. Moisture from the storm coalesced over the Al Hajar Mountains in northern Oman, producing severe thunderstorms that led to flash flooding. Across southern Oman where the storm crossed, there were no deaths; all of the deaths occurred due to the flash floods in northern Oman, where 14 people lost their lives. Three people were killed due to electrocutions, another two were crushed to death by large objects, and nine drowned. Overall damage was estimated at US$80 million, and over 200 people were injured nationwide.
