Monsoon winds are expected to enter upper and middle areas of the country, said the weather department on Monday, adding that the rain spell would take place along with storms and lightning.

Similarly, rain showers will also occur in areas of the southwestern Balochistan province and the northern Gilgit Baltistan region from August 15 to 18.
