Warning Sirens Sound as Water Level Surges
Heavy monsoon rain has raised fresh flooding concerns in Rawalpindi and Islamabad after the water level in Nullah Lai crossed 22 feet at Kattarian on Wednesday.
Authorities sounded warning sirens near the waterway as continuous rainfall caused water levels to rise rapidly. The Pakistan Meteorological Department has warned that further heavy rain could trigger urban flooding in low-lying areas of the twin cities.
The water level at Kattarian crossed 22 feet during the peak of the rain, while Gawalmandi Bridge recorded around 16 feet. Earlier readings stood at approximately 19 feet and 15 feet, respectively.
The situation later improved as rainfall eased.
According to the Flood Control Room, the water level at Kattarian dropped to around 17 feet, while Gawalmandi was also recorded at approximately 17 feet.
Despite the decline, authorities have maintained precautions because intermittent rain continues and another intense spell could cause Nullah Lai to rise again.
Rain has been falling intermittently across Rawalpindi and Islamabad since Monday night. The latest reported totals included 66mm at Saidpur, 65mm at Bokra and 63mm at Pirwadhai. Golra recorded 52mm, while Shamsabad and Chaklala received 50mm and 47mm, respectively.
Other monitoring points reported even heavier accumulations during parts of the wider rain spell, highlighting significant variation across the twin cities.
Rescue 1122 Warns Residents as WASA Deploys Heavy Machinery
Rescue 1122 issued safety announcements in communities surrounding Nullah Lai as water levels moved toward dangerous levels.
Residents were advised to avoid unnecessary travel and remain away from swollen streams, drains and other waterways.
Parents were particularly advised to keep children away from stormwater drains, electricity poles and exposed electrical infrastructure during the rain.
Authorities also urged motorists to exercise additional caution in waterlogged areas.
The Water and Sanitation Agency has deployed emergency teams along Nullah Lai and in areas vulnerable to urban flooding.
WASA Managing Director Azizullah Khan said teams were monitoring water levels and remained prepared to respond to emergencies.
Heavy machinery was deployed at Sadiqabad, Dhok Khaba, Pirwadhai, Arya Mohalla and Bohar Bazaar.
Additional equipment had also been positioned at Liaquat Bagh, Committee Chowk Underpass, Murree Road, Circular Road and other areas vulnerable to water accumulation.
WASA said garbage deposited in Nullah Lai during an earlier rain spell had been removed, allowing water to flow without major obstruction.
Residents were asked not to throw waste into drains and sewers.
They were also warned against removing sewer covers, which can create dangerous conditions and obstruct drainage during heavy rainfall.
More Rain Forecast Through August 21
The threat has not completely passed despite falling water levels.
The Pakistan Meteorological Department has forecast rain, wind and thunderstorms across Islamabad and upper Punjab through August 21, with occasional breaks in the weather.
Heavy rainfall during the period could again cause urban flooding in low-lying areas of Rawalpindi and Islamabad.
Authorities have therefore been advised to remain vigilant as monsoon conditions continue.
A rain-producing weather system remains active over the Potohar region and nearby areas, increasing the possibility of further thunderstorms.
Nullah Lai is closely monitored during intense monsoon spells because rapidly rising water levels can threaten densely populated neighbourhoods along its route.
Although Wednesday’s decline in water levels provided temporary relief, officials remain concerned that another heavy downpour could quickly increase the flood risk.
Residents in vulnerable communities have been advised to follow official warnings, avoid flooded roads and immediately contact emergency services if conditions deteriorate.
