Karachi/Islamabad, Pakistan - For Shahzad Ahmed, there was no time to think.
"The windows broke and the door caved in, that's how intense the water pressure was," he said of the first night of torrential monsoon rain in Karachi, Pakistan's largest city, last week.
We didn't even try to take the water out of the house. I just tied my rickshaw [to a pole] as tightly as I could and my family and I [got on] the rooftop."
Ahmed, his wife and children spent more than 10 hours on that roof, in the pouring rain, as Karachi saw more than 230mm of rainfall in less than 12 hours, the most ever recorded, according to the Pakistan Meteorological Department.
This year, Pakistan has seen some of the most intense monsoon rains in years, with more than 189 people killed and thousands of homes washed away in flooding across the country, according to the country's National Disaster Management Authority
