The advisory outlines expected weather systems, the most vulnerable regions, intensifying threats, and how federal and provincial authorities are preparing emergency response measures to protect public safety.

According to the NDMA, temperatures are expected to rise significantly across most parts of the country, with several regions likely to experience extreme heat ranging between 40°C and 48°C.

Regions, including Southern Punjab, Sindh and Balochistan, are expected to remain under intense heatwave conditions during the forecast period.

The NDMA said provincial disaster management authorities have already initiated anticipatory actions in line with federal directives to tackle any emergency arising from extreme temperatures.

Public awareness campaigns have been launched, while emergency response teams, cooling centres and medical preparedness measures are being strengthened nationwide.

The NEOC stated that moist western weather systems may trigger light rain in northern areas, including the Pothohar region.

However, rapidly rising temperatures in Gilgit-Baltistan, upper Khyber Pakhtunkhwa, Azad Jammu and Kashmir and other mountainous areas are accelerating glacier melt, increasing the risk of landslides, flash floods and Glacial Lake Outburst Floods (GLOFs).

Areas, including Hunza, Nagar, Gilgit, Chilas, Astore, Shigar, Chitral, Kalam, Upper Kohistan, and parts of Azad Kashmir, have been identified as vulnerable to landslides.

The NDMA further warned that key routes, including the Karakoram Highway, Shigar Valley Road, Skardu Road and Deosai Road, may face blockages due to falling debris and landslides.

The authority also identified Shimshal, Attabad Lake, Karimabad, Gulmit, Shishkat Bala and Passu as highly sensitive areas where road connectivity may be disrupted due to unstable mountain slopes.

Due to rapidly melting glaciers and the possible bursting of glacial lakes, flood-like situations may emerge in Darkot, Lasht, Reshun, Booni, Swat, Shisper, Golgin, Hanarchi, Roshan and Kumrat.

Mountain streams and rivers in Hunza, Ghizer, Diamer, Astore, Ghanche, Shigar, Chitral, Dir, Swat and Kohistan may also witness unusually high water flows.

In Sindh, districts including Jacobabad, Qamber Shahdadkot, Dadu, Jamshoro, Khairpur, Sanghar, Umerkot, Sukkur, Ghotki and Mirpurkhas are expected to remain under severe heat stress.

Similarly, Chagai, Washuk, Kharan, Turbat, Dera Murad Jamali, Usta Muhammad, Sibi, Lehri, Naseerabad and Jaffarabad in Balochistan are likely to experience extreme temperatures.

Punjab regions, including Multan, Lodhran, Rahim Yar Khan, Bahawalpur, Bahawalnagar, Toba Tek Singh, Jhang, Muzaffargarh, Bhakkar, Layyah, Lahore, Sahiwal and Kasur are also expected to face intensified heatwave conditions.

The NDMA said all relevant institutions have been directed to ensure emergency preparedness and preventive measures.

An additional advisory has also been issued regarding modifications in uniforms and dress codes during the heatwave.

According to the advisory, uniforms and clothing should be light colored and loose-fitting to reduce heat absorption and improve ventilation in extreme weather conditions.

 The guidance has been shared with all relevant departments and institutions.

The NDMA has instructed provincial disaster management authorities to accelerate precautionary measures in vulnerable areas and urged the public to avoid unnecessary travel and remain cautious during adverse weather conditions.

Residents and tourists in mountainous regions have been advised to stay alert to the risks of landslides and road closures, monitor weather updates closely and follow instructions issued by local authorities.
