LAHORE, Sept 17: Intermittent downpour on Monday turned the Punjab capital roads and streets into lakes and ponds, bringing life to a standstill.

Inundation of major thoroughfares coupled with digging of Ravi Road, Lower Mall, Lytton, Ferozpur and other roads for the metro bus system resulted in worst-traffic jams.

The downpour also disrupted electricity supply to many parts of the city that could not be restored till the filing of this report at midnight. Weather pundits said that Monsoon currents were penetrating in upper parts of the country.

A strong westerly wave affecting upper parts of the country is likely to persist for next 24 hours and it may cause scattered rain or thundershower with isolated heavy falls in upper Punjab, upper Khyber Pakhtunkhwa and Gilgit-Baltistan while widespread rain or thundershower with isolated heavy falls in Kashmir.
