The Pakistan Meteorological Department (PMD) has extended its rain forecast for Karachi, predicting thunderstorms and heavy downpours from 27 to 31 August. Isolated areas could experience very heavy rainfall, raising concerns about urban flooding in low-lying regions.
Fishermen have been advised to take precautions during this period due to the risk of rough seas.
The weather department issued an alert regarding a monsoon system expected to enter Sindh from 25 August. A low-pressure system currently over central India is moving westwards and is expected to reach eastern Sindh by the evening of 25 August or the morning of 26 August.
Under the influence of this system, Karachi is likely to see intermittent rain accompanied by thunderstorms and strong winds from 27 to 31 August.
Rain with thunderstorms is also expected in Badin, Thatta, Sujawal, Hyderabad, Tando Muhammad Khan, Tando Allahyar, and Matiari districts from 25 to 30 August.
Additionally, heavy to very heavy rainfall is expected between 26 and 30 August in Ghotki, Sukkur, Khairpur, Kashmore, Naushahro Feroze, and Shaheed Benazirabad districts.
The meteorological department warned that heavy rains could lead to water accumulation in low-lying areas across Karachi and other districts in Sindh.
There is a risk of rough sea conditions during the forecast period, and fishermen are advised to follow safety precautions.
On Saturday, Karachi recorded a maximum temperature of 35.2 degrees Celsius, with humidity levels at 67 per cent. Rural districts of Sindh remained under a heatwave, with Tando Jam recording the highest temperature of 39.5 degrees Celsius.
