Karachi, the heatwave is upon us. As temperatures rise, it's important to stay safe.  Mercury could rise to 41 degrees Centigrade today (Sunday). Sardar Sarfaraz, the director of Karachi’s Met department, says temperatures will remain between 41 and 42 degrees on Sunday and Monday. It's likely to cool down on Tuesday evening.
