Karachi has experienced continuous heavy monsoon rains since August 17, 2025, leading to widespread urban flooding and severe disruption across the city. Various areas reported light to torrential downpours with thunder and lightning, resulting in water accumulation on major roads including University Road and Shah Faisal Road, causing traffic paralysis. The city's drainage system failed to cope, exacerbating flooding issues and damaging infrastructure. The rain-related incidents have caused fatalities, with the death toll rising from eight on August 19 to 15 by August 20. The flooding also led to multiple accidents and electrocutions. Concurrently, on August 21, a massive explosion occurred at a fireworks warehouse on MA Jinnah Road in Karachi’s Saddar area. The blast triggered a fire, injuring at least 28 people, including the factory owner, and resulted in five confirmed deaths. The explosion caused significant damage, including to an adjacent girls' school. Rescue operations were conducted, and the fire was eventually brought under control. The incident added to the city's ongoing crisis amid persistent rainfall. Authorities forecast continued heavy rains in Karachi through August 23, with further precipitation expected from August 24 onward. The flooding and explosion have highlighted deficiencies in the city's infrastructure and emergency response capabilities. The economic impact is notable, with losses estimated at 10 billion Pakistani rupees. Efforts to clear water from roads and underpasses have been underway, but many areas remain waterlogged. The situation remains fluid with ongoing rainfall and recovery efforts.
