the super cyclone which slammed orissa in 1999 was with an approximate wind speed of
1999 Odisha cyclone The 1999 Odisha cyclone (IMD designation BOB 03,[1] JTWC designation 05B[3]) was the strongest recorded tropical cyclone in the North Indian Ocean and among the most destructive in the region.[note 1] The 1999 Odisha cyclone organized into a tropical depression in the Andaman Sea on 25 October, though its origins could be traced back to an area of storms in the Sulu Sea four days prior. The disturbance gradually strengthened as it took a west-northwesterly path, reaching cyclonic storm strength the next day. Taking advantage of highly favorable conditions, the storm rapidly intensified, attaining super cyclonic storm intensity on 28 October before peaking with winds of 260 km/h (160 mph) and a record-low pressure of 912 mbar (hPa; 26.93 inHg). The storm maintained this intensity as it made landfall on Odisha on 29 October. The cyclone steadily weakened due to persistent land interaction and dry air, remaining quasi-stationary for two days before slowly drifting offshore as a much weaker system; the storm dissipated on 1 November over the Bay of Bengal.
2017 North Indian Ocean cyclone season The season officially had an early start compared with the last two seasons, with the formation of Cyclone Maarutha over the Bay of Bengal in mid-April. Cyclone Mora, formed in late May over the Bay of Bengal. At its peak intensity, it was equivalent to a marginal Category 1 hurricane on the Saffir-Simpson hurricane wind scale. The cyclone produced severe flooding across Sri Lanka, India, Myanmar and Bangladesh and caused 15 deaths directly and 208 deaths indirectly. The floods persisted in Bangladesh since a Deep Depression over Bay of Bengal made landfall and killed 156 people in Bangladesh. A depression formed in northwestern Bay of Bengal and produced torrential rainfall. It was followed by a depression over Jharkhand which killed 70 people in West Bengal. Under the influence of strong monsoon surge a disturbance developed over Bay of Bengal travelled westwards and intensified to an unnamed depression. It also affected neighboring Karachi in Pakistan. A strong monsoon surge prevented formation of systems until a deep depression formed over West Bengal in October and caused heavy rainfall. A couple of depression formed between mid October and November which continued the rain spell causing destruction of life and property. Very Severe Cyclonic Storm Ockhi formed in early December and wreaked havoc in the countries where it impacted. It was equivalent to a strong Category 3 hurricane on the Saffir-Simpson scale at peak intensity. The twin storm of Ockhi was a deep depression which originated in Bay of Bengal while its counterpart was in Arabian Sea.
