A mosque is submerged after Cyclone Yemyin made landfall in Balochistan

Pakistan has a 1,046-kilometre (650 mi) coastline along the Arabian Sea and the Gulf of Oman in the extreme south western part of the country. Though cyclones are rare in the Arabian sea, cyclones that form in this sea mostly move towards Indian state of Gujarat rather than Pakistan.

Cyclones form in which month?

A map showing the up coming Monsoon pattern in the Sub-Continent

Cyclones in the Arabian sea form mostly from May till June and then from September till October, monsoon season plays a vital role for the formation of cyclone in this basin. Tropical storms that hit Pakistan are mostly remnants by the time reach pakistan or make landfall in south eastern Sindh which is not very much populated they rarely move towards the Balochistan coast.

Each year before the onset of monsoon that is 15 April to 15 July and also after its withdrawal that is 15 September to 15 December, there is always a distinct possibility of the cyclonic storm to develop in the north Arabian Sea. There is a 98 per cent chance of cyclones to turn towards the Indian state of Gujarat, one per cent chance of moving towards the Gulf and one per cent chance of moving towards the Pakistani coast.

Is there any Cyclone warning centre in Pakistan?

There is only one warning centre in Pakistan that is situated in Karachi. That too I suppose might be out of order.

    I think there was also a cyclone in 1993, that was about to hit karachi but it diverted in the last moment.

    • I have written about it as well…The cyclone forced schools and offices to close in karachi as day turned into night on that day ..massive urban flooding hit karachi due to the storm..the cyclone weakened over the sea when it was near coastal Sindh but its remnants made landfall over Pak-indo border..this cyclone is the 4th deadliest cyclone in pak
