As the intense heat claimed at least eight lives in Karachi a day earlier, the Met Office has predicted that isolated heavy rainfall is expected to hit various parts of Sindh including Karachi today (Wednesday).

The Pakistan Meteorological Department (PMD), in a statement on Tuesday, predicted a dust-thunderstorm or rain with isolated heavy rainfall from June 26 to July 1 in various parts of the Sindh province.

Besides Sindh, rain is also expected in other parts of the country from tomorrow as low pressure of air is in the south of Indian Gujarat and monsoon winds from the Arabian Sea and the Bay of Bengal will enter the eastern parts of the country on June 26.

The PMD's forecast comes as the metropolis has been gripped with extreme temperatures in recent days with the mercury reaching 42°C with the "feels like" temperature recorded at 51°C yesterday (Monday).

Furthermore, rains are also expected from June 27 to July 1 in Islamabad, Rawalpindi, Lahore and other cities.
