Pakistan is bracing for a heat wave with temperatures expected to climb as high as 50 degrees Celsius in the country’s most populous province where people have been asked to stay indoors. “Temperatures are expected to climb as high as 50 degrees in southern Punjab and some areas of Sindh,” chief meteorologist Sardar Sarfraz told the dpa news agency on June 20. The Pakistan Meteorological Department issued an advisory saying day temperatures are likely to remain 4 to 6 degrees higher than normal in Punjab and some parts of Sindh. Temperatures in northern areas, home to over 7,000 glaciers, are expected to be 2 to 4 degrees above normal. The sweltering conditions will continue to persist from June 20 through June 24.
