PMD director added that low pressure in the Bay of Bengal has turned into a depression, which may worsen with time and turn into a deep depression. 

The deep depression is likely to cause rains in South Punjab and Upper and Lower Sindh, Sardar Sarfaraz added. 

Under the influence of the system, rains are expected in Karachi after September 18, however, a hot and humid climate will prevail before that.
