ISLAMABAD: The upper and central parts of the country will see vigorous monsoon activity during the week, the meteorological department said Monday, asking authorities to remain alert and take necessary measures to avoid any untoward situation.

However, as Karachi endures scorching heat and experiences its highest night temperature since 2021 a day earlier, there is no forecast of rain in the city.

"Vigorous monsoon activity [is] predicted in [the] upper and central parts during the week. Torrential rainfall in [the] upper parts of the country may cause devastating effects on daily routines," the Pakistan Meteorological Department (PMD) said in a statement.

The Met Office informed the public that strong monsoon currents from the Arabian Sea and the Bay of Bengal are likely to penetrate the upper parts of the country from July 3.

Under the influence of this weather system:

Moreover, torrential rains are likely to cause flash floods in local nullahs and streams of Islamabad, Rawalpindi and other cities. Water flows in the eastern rivers are likely to increase during the vigorous activity of monsoon. Additionally, landslides may also disrupt roads at the vulnerable points of hilly areas.

All authorities concerned have been advised to remain "alert” and take necessary measures to avoid any untoward situation.

Low to medium-level flood likely in River Sutlej

Based on predictive modelling, the National Disaster Management Authority (NDMA) activated its National Emergencies Operation Center (NEOC) in the wake of upcoming monsoon rains.

As per a statement issued by the authority, the NEOC reported significant activity from the eastern Indian side of the country, indicating intense cloud bursts that may hit parts of Pakistan.

It stated that repeated early warnings have been shared with all provinces ahead of the predicted moderate to heavy rainfall.

The NDMA said that the upper catchments of all major rivers particularly Sutlej, Ravi and Chenab will be affected by heavy to moderate showers starting from July 2, 2024.

The authority also issued an alert regarding lightning during rain spells, likely in various cities of south and central Punjab and Islamabad during July 5-7.

The said weather conditions lead to rapid rises in water levels, flash flooding events, and urban flooding in metropolitan areas.

"NDMA warns that the anticipated rainfall poses a significant risk of low to medium level flooding in River Sutlej, with water levels expected to reach low flood levels (approximately 50,000 cusecs) by July 5 and high flood levels (approximately 120,000 cusecs) by July 10, 2024," the statement read.

The NDMA is working closely with federal and provincial departments to ensure preparedness and response to this potential emergency.

It also advised to remain vigilant and follow instructions from local authorities and stay informed about the weather and flood situation through its disaster alert mobile app.

Meanwhile, travellers were advised to avoid unnecessary travel in case of heavy rainfalls and likely flooding situations.
