KARACHI: Cyclone Vayu has been upgraded to a category one cyclone with rain and thunderstorm expected in Badin, Thatta and Tharparkar districts of Sindh.

According to the Pakistan Meteorological Department (PMD), Tropical cyclone Vayu in the East Arabian Sea has intensified as ‘very severe cyclonic storm’and moved further north-northwestward during last six hours, now lay centered around Lat.18.N and Long.70.0E at 0800PST at a distance of about 725 km southeast of Karachi. The maximum sustained surface winds are 135-145 km/hour gusting to 160 km/hour around the system centre.

The MET office further said, “Vayu is likely to continue to move in northerly direction. Under the influence of this system, widespread dust and thundershowers with scattered heavy to very heavy falls are expected in southeast Sindh (Thatta, Badin and Tharparkar districts) on Thursday and Friday. While scattered/isolated Dust-thundershowers may occur in rest of Sindh during the period.”

Seabreeze is likely to remain cutoff on Thursday and Friday (June 13-14) which can lead to heatwave like conditions in coastal areas of Sindh including Karachi, the MET office added.
