The downpour surpassed the previous April record of 37mm set on April 2, 1985, marking an extraordinary weather event for the metropolis.
Temperatures dropped sharply following the rain, with the minimum recorded at 16°C—around 5.8°C below the seasonal average of 21.8°C—leaving residents experiencing unseasonably cold conditions.
According to the Met Office, the westerly weather system responsible for the rainfall is moving southeast but will continue to affect other parts of the country until April 4. Karachi is expected to see partly cloudy skies with light rain or drizzle, with no further heavy showers forecast.
The rain-related incidents turned deadly, with at least seven people losing their lives over two days. One fatality occurred in Gulistan-e-Jauhar due to electrocution, while multiple deaths from electric shocks were reported in Surjani Town, PIB Colony, and near MA Jinnah Road.
In separate incidents, a wall collapse in Old Golimar killed a rickshaw driver, while another collapse in Orangi Town injured three children, who were shifted to hospital by rescue teams.
The heavy rainfall caused widespread disruption across the city. Low-lying areas remained submerged for hours, particularly Safoora Chowrangi and Hassan Square, leading to severe traffic congestion. Power outages were also reported as multiple electricity feeders tripped, leaving several neighbourhoods without electricity.
Rainfall data showed Nazimabad as the hardest-hit area with 97.4mm, followed by Keamari (76mm) and Surjani Town (67mm), while DHA, Orangi Town, and Jinnah Terminal also recorded significant precipitation.
The impact extended beyond Karachi, with other parts of Sindh, including Mohenjo-Daro, Jacobabad, Dadu, and Hyderabad, also receiving notable rainfall.
Authorities said efforts are underway to drain accumulated water and restore traffic flow, while maintaining alert as the weather system continues to move across the region.
