PMD issues Glof alert for GB, KP amid soaring temperatures

The Pakistan Meteorological Department (PMD) has issued an alert for glacial lake outburst floods (Glofs) for Gilgit-Baltistan and Khyber Pakhtunkhwa, predicting that soaring temperatures across the two regions are likely to persist until the first week of July.

“This significant warming will substantially accelerate snow and ice melt in the glaciated valleys of these regions,” the Met Office said in the alert issued late on Friday.

It said that consequently, the water level in the river streams was likely to remain high, existing glacial lakes may rapidly expand with an increase in their water levels, and new glacial lakes were likely to form due to the high volume of melted water.

Meanwhile, vulnerable downstream locations and low-lying areas adjacent to riverbeds may face a high risk of sudden inundation with chances of flash flooding in vulnerable locations, it added.

The Met Office further said that the rapid expansion of glacial lakes could destabilise their natural ice or moraine dams, potentially triggering Glof incidents.

The weather conditions can trigger heavy mud and debris flows down mountain slopes, with an increase in the likelihood of landslides in steep terrains, the PMD said.

It advised residents and visitors: to stay away from riverbanks, stream beds, and local nullahs; to refrain from camping, trekking, or staying near riverbanks, streams, glacial lakes and narrow mountain valleys; and avoid steep slopes and unstable terrain where melting snow could trigger landslides or debris flows.

Earlier this month, the Space and Upper Atmosphere Research Comm­ission (Suparco) identified 130 potentially dangerous glacial lakes with possible risks to downstream settlements from Glofs.

Separately, the KP health department had instructed hospitals in the province to establish heat wave emergency units for the proper management of sunstroke victims due to soaring temperatures.

Ailing Pope Francis to embark on Asia trip, his longest ever, in September

Pope Francis will travel to Indonesia, Papua New Guinea, Timor-Leste and Singapore from September 2-13, the Vatican said on Friday, announcing his first overseas trip of the year and the longest of his 11-year papacy. The Asia trip has been on the papal agenda for some time, but there had been doubts on whether the 87-year-old pontiff would embark on it given his increasing frailty, with a record of skipping engagements due to health problems. His last international journey was a two-day stay in Marseille, France in September. In November, he pulled out of a trip to the COP28 climate conference in Dubai because of a lung inflammation . Francis is now scheduled to be in Jakarta between Sept 3-6, Port Moresby and Vanimo between Sept 6-9, Dili September. 9-11 and Singapore Sept 11-13, his spokesman said in a statement. Vietnam, which had been suggested by the pope and Vatican officials as a possible further destination during the nearly two-week long Asia trip, was not mentioned. In ...

‘A war out there’: Maple Leafs survive shootout thriller in Utah

SALT LAKE CITY — Whew. They needed this one, even if they didn’t wholly deserve it. For a Monday night in Salt Lake City, the stakes felt unusually high for the sagging, road-weary Toronto Maple Leafs .  Heading into their inaugural game at Delta Center, the Leafs had dropped three straight, blown a couple leads, slipped out of first place, and  distracted  the fan base by propositioning their best player with a trade.  Worse: Their process hasn’t been tight for a couple weeks. Mistakes have crept in. Speed is giving their defence issues. And their razor-sharp goaltenders have begun to look human. Head coach Craig Berube held an intense team meeting Sunday, following Saturday’s 7-4 outclassing in Denver. Multiple players spoke up. Captain Auston Matthews said they’d reached look-in-the-mirror time. “The really bad games have a good way of being the biggest learning experiences,” thoughtful goaltender Joseph Woll said, following Monday’s slump-snuffing, nail-b...
