F.P. Report

ISLAMABAD: The above normal monsoon rainfall in the country has increased risks of flooding, landslides and urban floods in mega urban centers and vulnerable districts leaving public life, property and livestock at risk during inclement weather.

The National and Provincial Disaster Management Authorities (NDMA & PDMAs) following the Pakistan Meteorological Department (PMD) weather alerts of torrential rains have issued directives to the departments concerned to scale up mitigation and disaster management activities to cope with the impending risk of flooding and landslides.

Director, National Agromet Center PMD, Dr Khalid Mahmood Malik told APP that the country on average received approximately 140 to 145 millimeter rainfall (143mm recorded exactly) during monsoon season whereas the rainfall volume exceeding this number was termed “above normal monsoon rainfall”. He added that the above normal rainfalls were dangerous which might create massive water volume in a very short time and cause urban flooding.

Dr Khalid said there was no concept of ‘superflood’ scientifically as quoted by some quarters in the media while referring to the 2010 heavy floods. “There is no such scientific term rather massive flood is the appropriate terminology.”

The Met Office Director further explained that above normals could not be linked to massive floods technically, however, if heavy showers of rain start at a fast pace could cause flood. Dr Malik explained that the scattered showers with intervals did not garner much water in the catchment area which could not cause any flood.

The PDMA Punjab has warned the masses to take precautionary measures during monsoon season as the province received 57% more rainfall than average and the trend would continue in the coming days.

The PDMA also shared the weather advisory of Regional Met Centre predicting heavy rainfall from June 20 to 23 that might cause landsliding and flash flooding in vulnerable areas of Kashmir and Punjab. It also underlined the risk of urban flooding in major cities particularly Rawalpindi, Sargodha, Gujranwala, Sialkot, Lahore, Faisalabad, Sahiwal, Multan and Dera Ghazi Khan.

The district administrations of the above mentioned urban centres were directed to ensure desilting and cleanliness of tributaries, nullahs and drains to avoid urban flooding risk by the PDMA. The National Weather Forecasting Center of PMD recorded maximum rainfall in districts of Punjab including Jhang 98mm, Dera Ghazi Khan 69mm, Bhakkar 63mm, followed by Khyber Pakhtunkhwa, 64mm in Dera Ismail Khan.
