The 1963 North Indian Ocean cyclone season had no bounds, but cyclones tend to form between April and December, with peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. There are two main seas in the North Indian Ocean—the Bay of Bengal to the east of the Indian subcontinent and the Arabian Sea to the west of India. The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center releases unofficial advisories. An average of four to six storms form in the North Indian Ocean every season with peaks in May and November.[1] Cyclones occurring between the meridians 45°E and 100°E are included in the season by the IMD.[2]

Systems

Deep Depression One

Deep depression (IMD)
Tropical depression (SSHWS)
 
DurationJanuary 3 – January 5
Peak intensity45 km/h (30 mph) (3-min);

This tropical depression stalled for three days.[3]

Extremely Severe Cyclonic Storm Two

Extremely severe cyclonic storm (IMD)
Category 1 tropical cyclone (SSHWS)
 
DurationMay 18 – May 29
Peak intensity195 km/h (120 mph) (3-min);
947 hPa (mbar)

On May 19, a tropical disturbance formed over the Laccadive Islands, before tracking northwest towards the Arabian peninsula. The system achieved cyclone intensity on May 22. On May 24, a United States Weather Bureau reconnaissance aircraft flew into the 19 km (12 mi) eye of the storm, encountering winds of 193 km/h (120 mph).[4] A ship 111 kilometres (69 mi) west of the system reported winds of 68 knots (126 km/h). At Salalah, a strong northerly wind set in during the morning of May 25. Later in the day, winds increased to gale force and a sandstorm reduced visibility to 400 metres (1,300 ft). Later in the day of May 26 winds again increased to gale force and another sandstorm reduced visibility to 500 metres (1,600 ft). As winds increased to 60 knots (110 km/h) the sandstorm became more severe, with visibility restricted to 50 metres (160 ft). Late on the night of the 26th, winds shifted to northeast and heavy rains fell across the region through the morning hours. Skies remained cloudy with periods of rain into May 28. A total of 230 millimetres (9.1 in) was recorded at Salalah.[5][6] An estimated 22,000 people were reported to have died, while a further 500,000 were left homeless.[7]
