The storm quickly weakened over land, as dry air and land interaction diminished the convection. Early on September 25, the IMD downgraded Hikaa to a deep depression, and later to a low-pressure area, by which time the storm was near the border of Oman and Saudi Arabia.

of 140 km/h (85 mph). Around the same time, the JTWC estimated peak 1 minute winds of 155 km/h (95 mph), based in part on the 26 km (16 mi) eye in the center of the convection. As Hikaa was nearing land, the eye deteriorated, and the JTWC assessed that the storm weakened. The IMD meanwhile assessed that the cyclone maintained its peak intensity. Around 14:00 UTC on

Considering the storm a "midget tropical cyclone", the JTWC upgraded Hikaa to the equivalent of hurricane status late on
September 23, while the storm was approaching eastern Oman. The IMD followed suit, upgrading Hikaa to a very severe cyclonic storm on September 24, estimating peak winds
