KARACHI: The Pakistan Meteorological Department (PMD) has issued an advisory warning that a tropical weather system forming over the Bay of Bengal is advancing toward the Arabian Sea and could affect coastal Sindh, including Karachi, over the next few days.
According to the PMD advisory, the low-pressure area, which has been building strength over the Bay of Bengal, is expected to move across India and enter the Arabian Sea near Gujarat. Meteorologists said the system may trigger changes in atmospheric conditions, bringing spells of rain and thunderstorms to parts of southeastern Sindh.
The advisory noted that while marine conditions are likely to remain stable at the outset, disruption is expected once the system moves closer to the Arabian Sea. Fishermen and coastal communities have been advised to remain alert as the situation develops.
Currently, Karachi is experiencing oppressive heat and humidity, with maximum temperatures forecast to hover between 35–37°C until Wednesday. The Met Office said the city is likely to see “extreme hot and humid” weather today, followed by cloud build-up and possible rainfall on September 30 in the afternoon or evening.
Districts including Tharparkar, Umerkot, Badin, Sujawal, and Sanghar are forecast to receive light to moderate rainfall accompanied by thunderstorms between September 29 and 30. The weather in these districts is expected to remain partly cloudy, offering some respite from the prevailing heatwave conditions.
Meteorologists emphasized that the full impact of the tropical system will depend on its trajectory and strength as it enters the Arabian Sea. “At this stage, it appears southeastern and lower Sindh, including Karachi, could be affected, but further updates will refine the forecast,” an official said.
The PMD added that hot and humid weather would continue in most parts of Sindh early next week, though localized rainfall could provide temporary relief in some areas.
The developing system follows a pattern of unusual weather disturbances in the region, which forecasters link to shifting climatic conditions. The Met Office is closely monitoring the low-pressure area and will issue further advisories as the system progresses.
