Latest Verified Flood Update
1 September 2026 — the most recent major event. Torrential rain began around 3:20am and continued until about 8am across the twin cities. The Pakistan Meteorological Department recorded 197mm at Shamsabad, 185mm at New Katarian and 157mm at Golra — nearly 200mm across Rawalpindi, its heaviest downpour in three years, with around 150mm in Islamabad’s E-11 sector. Nullah Lai surged to 29 feet at Katarian and 23.5 feet at Gawalmandi, both above evacuation thresholds. Authorities declared a rain emergency, closed all educational institutions for the day, positioned Rescue 1122 along the channel, evacuated vulnerable riverside localities (Safdarabad, Dhoke Khaba, Pirwadhai, Arya Mohalla among them), and called in the Pakistan Army as a major flood surge passed through. One death was reported.
Earlier in the season: on 17 July 2025, three consecutive days of rain pushed Nullah Lai to 22 feet at Katarian with flood sirens sounded; levels later receded. Monsoon 2025 also brought repeated PMD flood alerts for the nullah through July and August.
How to Check Today’s Flood Situation
- PMD flood control room: publishes live Nullah Lai gauge readings (Katarian, Gawalmandi) and heavy-rain warnings during monsoon spells.
- NDMA advisories: national alerts for urban flooding, flash floods and landslides, plus the national emergency helpline.
- District administration (Rawalpindi / ICT): official pages announce sirens, school closures, rain emergencies and evacuation orders.
- Rescue 1122: on-ground rescue coordination and public safety instructions.
Treat viral social-media videos with caution during floods — old footage from 2001 or 2022 routinely recirculates as “today”. Cross-check any dramatic claim against PMD or NDMA channels before sharing.
Reading Nullah Lai Levels
The two gauges that matter:
- Katarian: readings approaching 20+ feet bring warning sirens and precautionary evacuations.
- Gawalmandi Bridge: inundation of low-lying areas along the channel typically begins near 18 feet.
For context: on 1 September 2026 the gauges read 29 feet (Katarian) and 23.5 feet (Gawalmandi); in the record 2001 cloudburst, Nullah Lai reached about 34 feet.
Monsoon Season Outlook
Pakistan’s monsoon runs July to September, with the heaviest flood risk in July and August. The capital region’s pattern is well documented: intense bursts on the Margalla catchment, rapid Nullah Lai rises, and urban flooding in low-lying sectors and Rawalpindi’s old city. See our Islamabad flood guide for why this happens, the flood history for the record of past events, and what high alerts mean for the alert system explained.
What to Do Right Now
- Move away from Nullah Lai, streams and low-lying areas if rain is heavy — do not wait for the siren.
- Never drive through flooded underpasses, nullah crossings or waterlogged roads.
- Keep phones charged and follow PMD/NDMA updates, not forwarded messages.
- If water enters your home, switch off the main electricity breaker and move valuables upstairs.
- Emergency: call Rescue 1122.
