The National Emergencies Operation Center issued a nationwide heatwave alert for Pakistan, specifically targeting Sindh and southern Balochistan.
This alert signals a critical public health and safety risk as extreme temperatures threaten to cause widespread heat-related illnesses. The weather pattern also increases the likelihood of secondary disasters, such as landslides and flash floods, which can devastate infrastructure and rural communities.
Officials from the National Disaster Management Authority's operation center said that temperatures are expected to exceed 42°C [1]. While some reports indicated the alert period ran from May 19 to May 26 [1], other reports extended the warning period from May 26 through May 31 [2].
The geographic scope of the alert varies across reports. Some sources describe the warning as nationwide, covering the whole of Pakistan [3]. Other reports specify a more concentrated risk in parts of Sindh, including Karachi, as well as southern Punjab and eastern Balochistan [3].
In northern Pakistan, the intense heat is creating additional environmental hazards. Rising temperatures are accelerating the melting of glaciers, which increases the volume of water flowing into river systems, a primary driver for flash floods in the region [4].
Authorities said the public should take precautions against the heat and remain vigilant for weather-related emergencies. The combination of extreme heat and glacier melt creates a dual threat for both the arid south and the mountainous north.
“Temperatures are expected to exceed 42°C”
The simultaneous occurrence of extreme heat and accelerated glacier melt highlights Pakistan's vulnerability to climate volatility. By linking heatwaves in the south to flood risks in the north, the NEOC is acknowledging that thermal extremes do not just cause health crises but trigger a chain reaction of geological and hydrological disasters.
