Along the Odisha coast, the cyclone generated a 5–6 m (16–20 ft) storm surge that brought water up to 35 km (20 mi) inland, inundating a large swath of coastal areas. The Indian Ministry of Urban Development estimated a peak storm surge height of 6.7 m (22 ft). One visually estimated storm surge of 9 m (30 ft) was reported; however, this estimate was determined to have been too high. Regardless, no in-situ measurement of the peak storm surge exists as all potential instruments were destroyed by the storm. Storm surge was responsible for a majority of the fatalities linked to the 1999 Odisha cyclone, accounting for around 7,000 deaths. The intense wave action sank 9,085 fishing boats and caused the loss of 22,143 fishing nets. Some fishing trawlers were carried and deposited 1.5–2.0 km (0.9–1.2 mi) inland. A 4 km (2.5 mi) stretch of road leading out of Paradip was covered by sand dunes measuring 1 m (3.3 ft) in height and 0.5 km (0.3 mi) in width. Paradip Port sustained severe damage to several components including various warehouses and its power transmission system, though its core infrastructure remained intact. Damage at the port was estimated at around ₹300 million (US$6.9 million). The storm surge destroyed nearly every house in Paradip near the point of landfall. In Gopalpur, 27 villages were submerged by the surge. To the south in southern Andhra Pradesh, 48 trawlers sank. To the north in West Bengal, Substantial damage to housing was reported, causing injuries to 30 people in Midnapore.
