Flood alert
Tarbela is effectively full, Mangla is filling fast, and the NDMA has warned of low to moderate flooding across Khyber Pakhtunkhwa, Punjab, Balochistan and Azad Jammu and Kashmir. More than a dozen cities have been flagged for urban flooding as the monsoon peaks.
The core problem is simple. Reservoirs that would normally absorb a surge are already close to capacity, so incoming monsoon flows have nowhere to be stored and must be passed downstream. That is why the warnings this month cover both hill torrents and city drainage.
What the NDMA has warned
The National Disaster Management Authority’s National Emergencies Operation Centre has issued advisories covering river conditions, dam storage and flooding potential across Khyber Pakhtunkhwa, Punjab, Balochistan and Azad Jammu and Kashmir. The assessment is low to moderate flooding in parts of the country — not a nationwide catastrophe warning, but a sustained elevated-risk period.
Flood alerts have been issued around the Sukkur, Marala and Balloki barrages as flows rise, and the authority has separately warned of flood risk in the Rajanpur and Dera Ghazi Khan areas.
Where the water is
| Reservoir | Level | Storage | Same period 2025 |
|---|---|---|---|
| Tarbela | 1,548 feet | 97.94% | 95.98% |
| Mangla | 1,205.2 feet | 62.99% | 62.80% |
Tarbela has since been reported at maximum conservation level, with Mangla around 67% full. Both are ahead of where they stood at this point last year, though Mangla only marginally so.
Full dams are not automatically bad news
High storage going into late August is good for winter irrigation and hydropower. The risk is specific and short-term: a full reservoir has no spare capacity to absorb a sudden inflow, so heavy rain upstream translates into downstream releases faster than it would in a dry year.
Cities flagged for urban flooding
Water accumulation has been feared in Islamabad, Rawalpindi, Lahore, Sheikhupura, Kasur, Faisalabad, Multan, Sahiwal, Okara, Bahawalnagar, Gujranwala, Gujrat, Sialkot, the Potohar region, Peshawar and Nowshera.
Urban flooding is a drainage problem rather than a river problem. It arrives quickly, peaks within hours, and is at its most dangerous in underpasses, basements and low-lying colonies. Heavy rain has already flooded low-lying areas in Rawalpindi and Islamabad this season.
Most monsoon deaths in Pakistani cities are not caused by rivers. They are caused by electrocution, roof collapse and vehicles entering standing water.
The three urban risks worth taking seriously
- Electrocution — standing water in contact with damaged wiring, street poles or generators. Do not wade through water near fallen cables or pole bases.
- Roof and wall collapse — a serious risk in older kacha structures after several consecutive days of saturation, not just during the heaviest downpour.
- Underpasses and low points — water depth is very hard to judge from a car, and stalling in a flooded underpass is how routine journeys become emergencies.
The mountain risk is different, and higher
The NDMA has issued a specific warning to people living in or travelling through mountainous regions, where monsoon weather can trigger flash floods, landslides and debris flows with very little warning.
This matters more than usual right now because of the timing. The 14 August long weekend pushed heavy tourist traffic onto the northern routes, and August remains peak season for the Galiyat, Kaghan, Swat and Gilgit-Baltistan corridors. A flash flood on a mountain road does not require rain where you are standing — it requires rain upstream.
If you are travelling north
Check the forecast and road conditions before setting out, not after. Stay away from riverbanks, nullahs and stream beds, including for parking and camping. Do not attempt to cross a flowing stream on foot or by vehicle. If a road is closed, treat the closure as final — most fatalities in these corridors involve people who went around a barrier.
What to do this week
- Know whether you are low-lying. If your street floods in an ordinary heavy shower, assume it will flood worse this month and move vehicles and valuables accordingly.
- Charge everything. Power cuts follow urban flooding almost automatically. Keep phones, power banks and torches topped up.
- Keep documents dry and duplicated. Photograph CNICs, property papers and bank documents and store the copies in the cloud — useful in any case now that NADRA has moved to a chipless CNIC.
- Clear your own drainage. Roof outlets, courtyard drains and street gullies immediately outside your gate are usually the difference between a wet street and a flooded room.
- Do not drive into standing water. The most common serious incident of the season, and the most avoidable.
How this season compares
Both major reservoirs are marginally ahead of last year’s storage at the same point, which tells you inflows have been strong rather than exceptional. What makes this August notable is the combination: high storage, continued monsoon activity and rising river flows arriving together.
The pattern has been consistent through 2026 — a punishing early-summer heat wave that turned Eid into a survival test, followed by repeated NDMA heavy-rain alerts from mid-June onward. Rapid swings between extremes are now the normal shape of the year.
Frequently asked questions
How serious is the current flood warning?
The NDMA’s assessment is low to moderate flooding in parts of Khyber Pakhtunkhwa, Punjab, Balochistan and Azad Jammu and Kashmir. It is an elevated-risk advisory rather than a major flood emergency, but conditions can change quickly during peak monsoon.
How full is Tarbela Dam?
Tarbela was recorded at 1,548 feet with storage at 97.94%, and has since been reported at maximum conservation level. Mangla was at 1,205.2 feet and about 63%, rising to roughly 67%.
Which cities are at risk of urban flooding?
Islamabad, Rawalpindi, Lahore, Sheikhupura, Kasur, Faisalabad, Multan, Sahiwal, Okara, Bahawalnagar, Gujranwala, Gujrat, Sialkot, the Potohar region, Peshawar and Nowshera have been flagged for possible water accumulation.
Is it safe to travel to the northern areas right now?
Travel is not prohibited, but the NDMA has specifically warned about mountainous regions, where flash floods, landslides and debris flows can occur with little warning. Check forecasts and road conditions before setting out and avoid riverbanks and stream beds.
Why is a full dam a problem?
A reservoir near capacity has little room to absorb a sudden surge, so heavy upstream rain has to be passed downstream rather than stored. High storage itself is good for irrigation and power; the short-term flood risk comes from the lack of spare capacity.
What is the single most dangerous thing to do?
Driving into standing water of unknown depth, particularly in underpasses. After that, walking through floodwater near damaged electrical infrastructure.
Where can I check official updates?
The NDMA and the Pakistan Meteorological Department issue the authoritative advisories, and provincial disaster management authorities publish district-level warnings. Reservoir figures change daily, so treat any published number as a snapshot.
