The prevailing intense pre-monsoon heat will continue for another five days in most parts of the country.
The Metrological Department on Wednesday forecasted that the prevailing intense heat is likely to subside after pre-monsoon rain and thundershowers accompanied by dust storms over Islamabad, upper Punjab, upper Khyber Pakhtunkhwa and Kashmir on Tuesday and Wednesday.
Met office further informed that a tropical cyclone is developing in eastern parts of Arabian Sea that is likely to move on in northwesterly direction towards Oman Coast in next couple of days.
Due to north-westward movement of tropical cyclone, the current intense heat wave over Pakistan is likely to further intensify and would extend northward towards Islamabad, Khyber Pakhtunkhwa and upper Punjab.
The heat wave will also envelop northern areas including Gilgit-Baltistan and Kashmir during the coming weekend triggering large scale snow-melting.
The inflows in all hilly rivers of Upper KP and GB-Kashmir and Tarbela Dam may increase substantially during the weekend.
