How Karachi Meteorological Department saved lives through its quick action

Reuters |

When an unseasonal and potentially deadly heat wave loomed on weather forecasts last month, authorities in this port city took an unusual step: They issued a public warning, a full week in advance. Before the heat hit, text message warning of the danger went out to Karachi residents. Hospitals set aside extra beds for heat stroke victims. Water and power company officials were put on alert.

Ultimately the heat wave, with temperatures that reached 41 degrees Celsius, passed without claiming lives, Karachi Mayor Waseem  Akhtar said. But the warning the first of its kind issued by the Pakistan Meteorological Department for Karachi may set the stage for more lifesaving warnings next summer as climate change drives temperatures higher.

October temperatures in densely populated Karachi normally rise no higher than 35 or 38 degrees Celsius, said Abdul Rashid, director of the Pakistan Meteorological Department office in Karachi.

Temperatures in the Arabian Sea are showing gradual rising trends for the last six years because of strange weather patterns, which mostly likely increase the frequency and intensity of cyclones, heat waves.

Heat waves in October are extremely rare incidents , he said. But being unprepared for extreme heat can be deadly. In 2015, a June heat wave killed about 1,500 people in Karachi, Pakistan largest city, and leftover 70,000 hospitalized most with heat stroke. Officials are now working to try to avoid a repeat of that heat disaster a particular challenge as climate change brings ever-hotter years, particularly in already broiling South Asia.

We now keep a closer watch on temperature, air, humidity (and) sunlight parameters of the Bay of Bengal and the Arabian Sea, and register these parameters regularly in the weather charts, which helped predict the October heat wave more accurately and timely, Rashid, of the met office, told the Thomson Reuters Foundation.

The Karachi office also has its own heat wave forecast division, with advanced computer systems connected to five heat wave monitoring stations recently installed around the city, he said. The system was set up following World Meteorological Organization warnings that more frequent and intense heat waves were becoming a possibility in the region.

In 2015, a June heat wave killed about 1,500 people in Karachi, Pakistan largest city, and left over 70,000 hospitalised, most with heat stroke.

Warning, then action In October, after spotting heat-producing weather conditions moving toward Pakistan from Mumbai and India Gujarat state, the office issued a warning to the Sind provincial government, the Karachi commissioner and provincial disaster management authorities, Rashid said. For Karachi mayor, the alert provided time to send out text alerts, contact media, warn hospitals and water and power utility officials and set up special units for heat victims in 13 city hospitals.

Dr Seemi Jamali, head of emergencies at the state-run Jinnah Postgraduate Medical Centre in Karachi, said the warning gave time to stock extra medicine, set aside beds and put medical staff on high alert. This really helped quickly arrange medical care facilities in hospitals for heat wave victims and avoid possible deaths she said in an interview in her office. Residents of Karachi said the unusual October heat is a worry.

October temperatures in densely populated Karachi normally rise no higher than 35 or 38 degrees Celsius, said Abdul Rashid.

Octobers have remained always warm in the port city, but I never experienced this blistering heat wave in all my life in this month, which made our home feel like a furnace, said Saba Karim, a 43-year-old garment factory worker. We all five family members, including my husband, stayed indoors during the heatwave days and would go outside only during night hours to buy groceries, she recalled.

Ghulam Rasul, head of the Pakistan Meteorological Department in Pakistan, said the country may be seeing a change in its traditional pattern of onshore winds blowing cooler air into Karachi over the summer months. The lack of that wind was one driver behind Karachi October heatwave, he said.

Dr Seemi Jamali said the warning gave time to stock extra medicine, set aside beds and put medical staff on high alert.

Temperatures in the Arabian Sea are showing gradual rising trends for the last six years because of strange weather patterns, which most likely increase the frequency and intensity of cyclones, heat waves, and torrential rains in months in which these were never or rarely seen before, said Rasul, who is also Pakistan permanent representative to the World Meteorological Organization.
