As Pakistan is experiencing a hotter than usual September with fans and air-conditioners still in full use, there is some good news from the west: a westerly wave is likely to start affecting the upper parts of the country within 36 hours.

In this connection, the Met Office in a press release said a western disturbance was likely to enter the upper parts of the country from Saturday (September 26) night, thus subsiding the prevailing hot weather conditions in upper and central regions of the country.

This weather system is expected to prevail till Wednesday (September 30), causing rains/wind and thunderstorms with occasional gaps in Khyber Pakhtunkhwa, Gilgit-Baltistan, Azad Kashmir, Islamabad and upper parts of Punjab.

Rawalpindi, Attock, Jhelum, Chakwal, Mianwali, Khushab, Sargodha, Hafizabad, Gujrat, Gujranwala, Sialkot, Narowal, Lahore, Sheikhupura, Faisalabad and Kasur are the districts in Punjab expected to be affected by the much-awaited weather system from the west.

The upper and central parts of Pakistan are under the influence of above than average temperature as no westerly has affected the country this September – a common feature that accompanies the withdrawal of monsoon.

Moreover, the country has received very little monsoon rain in the current month which complicated the situation and resulted in a higher temperature.
