Wide fluctuations between day and night temperatures are likely to cause health problems for people and livestock, the Met Office warned on Thursday, advising the public to take precautions as hot and dry weather continues across Sindh. The advisory from the Pakistan Meteorological Department’s Early Warning Centre in Karachi said the sharp difference between daytime and nighttime temperatures could affect human health and livestock. Karachi’s temperature fell by 1.1 degrees to around 37 degrees Celsius on Thursday, while humidity dropped to 20 percent. Hot and dry conditions are expected to persist over the weekend, with maximum temperatures likely between 35 and 37 degrees Celsius on both Friday and Saturday, and minimum temperatures of 21 to 23 degrees. Morning humidity is expected at 30 to 40 percent, falling to 20 to 30 percent in the evening. The warning matters most for outdoor workers, children, older people and anyone with breathing or heart problems. Drinking enough water, avoiding strenuous activity in the hottest hours and protecting livestock from sudden cold nights are the simple precautions the Met Office advises.
