LAHORE: The monsoon system from the Bay of Bengal began on Friday to give rain in many cities in the country in league with a westerly wave over the upper parts of the country, and the Met office said it was to unleash its fury mainly in Sindh and Balochistan in the next two days.
The Met department reiterated that the system might generate a very heavy to extremely heavy rain that might cause urban flooding in Sindh and hill torrents in Balochistan.
Extremely strong monsoon current was reaching lower portions of the country up to 10,000ft.
Luckily, it was not moving towards upper parts of the country otherwise this amount of moisture could give devastating rains over the cool upper catchments of the major rivers, generating extremely high floods in them, a meteorologist said.
Rain on Friday was generated by the monsoon current from the Arabian Sea and the Bay of Bengal and a westerly wave over the upper parts of the country.
It rained heavily in the central, western and southern Lahore, submerging roads and causing widespread traffic jams. Broken down motorcycles and cars dotted the inundated roads.
The Flood Forecasting Bureau said the depression over northeast Chhattisgarh moved westwards and lay over central Madhya Pradesh (India). It was likely to weaken into a well marked low. A westerly wave also persisted over the upper parts of the country.
