Islamabad and Rawalpindi observed delightful raining all over the cities here on Monday.

Another spell of rain is expected in Karachi on August 28 and 29, the Met Office said on Monday.

A low pressure area is likely to form over the Bay of Bengal that may cause light rain in Karachi and other areas in lower Sindh.

Earlier this month, at least 12 people were killed due to electrocution and various other rain-related incidents during a monsoon downpour in the metropolis.

The uninterrupted rain — recorded at almost 200 millimeters (mm), created a critical situation in Karachi as various areas were hit with hours-long power outages and urban flooding.

Major thoroughfares were drowned under several feet of rainwater, with drains and canals in the city overflowing and low-lying residential areas submerged in the water pouring in from the streets outside.
