Heatwave The forecast for wet weather followed below-normal rainfall across the country in March.

Last month, the PMD issued a drought alert for Sindh, Balochistan and Punjab due to scant rainfall.

The mean temperature during March 2025 in the lower half of the country was 2 to 3 degrees Celsius above normal, with consecutive dry days of no rainfall in some areas of the southern region even exceeding 200 days.

Overall, rainfall from Sept 1, 2024, to March 21, 2025, was 40 per cent below normal.

The dry spell created a shortage of water in Tarbela and Mangla dams and water flowing in different rivers was at an extremely low level.As per the PMD advisory issued on Tuesday, heatwave conditions are likely to continue in Sindh, south Punjab and parts of Balochistan till April 18.

Glof warning The KP Provincial Disaster Management Authority (PDMA) has issued a separate warning for possible glacial lake outburst floods (Glofs) in Lower Chitral, Upper Chitral, Upper Dir, Swat and Kohistan districts due to the ongoing heat wave.

Glof occurs when a lake formed within or beneath a glacier bursts due to the rapid melting of snow. It results in a sudden release of water, threatening mountainous communities.

The advisory sent to deputy commissioners of these districts stated that PMD has warned of an increased risk of Glofs in low-lyingglaciated areas of KP from Wednesday (today) due to a significant rise in temperatures.

`The persistent high temperatures may accelerate snow and glacier melt and subsequent weather events, potentially triggering Glof incidents in vulnerable valleys and surroundingregions duringthe current and upcoming week,` the advisory said.

PMDA has asked district administrations to take precautionary measures to avoid any loss of life and livestock and damages to infrastructure and crops.It also asked the relevant authorities to warn local communities of the risk and ensure the availability of emergency and rescue services personnel to deal with any emergency situation.

The advisory also warned tourists to avoid unnecessary travel to these areas.
