Unusually hot weather: Cloud seeding operations implemented to deal with critical water level at dams
The situation raised concerns about the water levels, public health and the economy in rural communities.
Deputy Prime Minister Datuk Seri Ahmad Zahid Hamidi stated that in areas such as Bandar Baharu in Kedah, Selama (Perak), Temerloh (Pahang), Limbang (Sarawak), as well as Tenom and Pitas in Sabah, temperatures ranged between 35 and 37 degrees Celsius, reported Sinar Harian.
He said that, given the situation, the government has implemented a Cloud Seeding Operation (OPA) in the Bukit Merah Dam area, Gunung Semanggol, Perak, whose water level was at a critical level.
According to him, the water reservoir level in the dam was only 12.21% or 19.80 feet.
"I, along with the National Disaster Management Agency (Nadma) director general, the Malaysian Meteorological Department (MetMalaysia) deputy director general and the Royal Malaysian Air Force (RMAF) have participated in this operation using a Charlie C-130 aircraft carrying approximately 6,000 litres of sodium chloride solution.
"The solution was sprayed on the towering cumulus clouds at an altitude of between 5,000 and 8,000 feet and within 45 minutes after spraying, heavy rain had occurred in the target area," he said at a press conference at RMAF Air Base Subang, on Monday (Aug 4).
"Bukit Merah Dam is not just a domestic water supplier but also supports agricultural, fishing, tourism and flood mitigation activities.
"If not dealt with immediately, this crisis could affect the food supply chain, the income of rural residents as well as the balance of the ecosystem," said Ahmad Zahid, who is also the Chairman of the National Disaster Management Committee.
He said the extremely hot weather also increases the risk of haze due to forest fires.
"Air Pollution Index (API) readings have increased in some areas, and this has an impact on health, especially to those at risk such as children, the elderly and respiratory patients," he said.
He further commented that cloud seeding operations might also be carried out in other regions based on the monitoring by technical agencies, even if the state government does not explicitly request it.
"We don't just wait for requests. If a water source is at a critical level of 30% or below, cloud seeding will continue to be implemented proactively.
"In addition, the fire department has also been on standby with more than 3,300 tube wells in peatland areas to prevent forest fires due to extreme heat," he said.
He explained that the Southwest Monsoon was expected to continue until mid-October and all related agencies have been instructed to prepare for any eventuality.
"I ask the Health Department, MetMalaysia and Nadma always to share information with the public.
"At the same time, extracurricular activities at school must also be coordinated with the District Education Office to prevent health risks to students," he said.

Number of wildfires soaring in Portugal
LISBON, Aug. 5 (Xinhua) -- Forest fires have consumed nearly 42,000 hectares in Portugal this year, eight times more than in the same period in 2024 and the highest figure since 2022, according to the Integrated Rural Fire Management System (SGIFR). Statistics from SGIFR indicate that since Jan. 1, there have been 5,211 recorded fires that burned a total of 41,644 hectares. SGIFR reports that 72 percent of the burned area and 53 percent of this year's fires occurred in the north of the country, where fires have been most intense in recent weeks in the districts of Viana do Castelo, Braga, Vila Real, and Porto. More than half of the burned area was consumed by flames in less than two weeks since July 26, and compared to the same period in 2024, the number of fires has nearly doubled, according to SGIFR. Although most fires are still under investigation, the data indicates that 19 percent were caused by the use of fire, and 14 percent by arson. The country has entered a state of alert from Sunday through Aug. 7 due to a severe heatwave and heightened wildfire risk, with temperatures expected to reach up to 44 degrees Celsius. The National Authority for Emergency and Civil Protection reported on its website that, as of Tuesday afternoon, 93 wildfires remained active across Portugal. A total of 2,440 firefighters, 766 vehicles, and 13 aircraft were deployed to combat the flames.

Japan sets record temperature of 41.8 deg C
TOKYO: Japan logged a new heat record on Tuesday (Aug 5), with the mercury hitting 41.8 deg C, the weather office said, warning temperatures may rise further still. Temperatures the world over have soared in recent years as climate change creates ever more erratic weather patterns, and Japan is no exception. The scorching temperature in the city of Isesaki on Tuesday surpassed the previous record in the Hyogo region of 41.2C, which was set only last week. Tokyo has also been struggling with extreme heat. "I'm really concerned about global warming, but when it comes to my daily life, I can't live without turning on the air conditioner," office worker Mayomi Saito told AFP. "I don't really know what I should be doing. I'm just desperately getting through each day." Last month, 38,608 people were treated in hospital for heatstroke, data showed Tuesday, down from 43,195 in July 2024. Last week there were 18 deaths. In tourist hotspot Kyoto last week the mercury hit 40C, the first time any of its observation points -- the oldest opened in 1880, the newest in 2002 -- had seen such a high, authorities said. Experts warn Japan's beloved cherry trees are blooming earlier due to the warmer climate -- or sometimes not fully blossoming -- because autumns and winters are not cold enough to trigger flowering. The famous snowcap of Mount Fuji was absent for the longest recorded period last year, not appearing until early November, compared with the average of early October. July was also the hottest since records began in 1898, the weather agency said Friday, with the average monthly temperature 2.89C above the 1991-2020 average. Japan's summer last year was the joint hottest on record, equalling 2023, and was followed by the warmest autumn since records began 126 years ago. - South Korea, Vietnam sizzle - Blistering heatwaves have also hit other parts of Asia this summer, from South Korea to Vietnam, as well as Europe. South Korea saw its second-hottest July, with an average temperature of 27.1C, according the meteorological office, which has been collecting such data since 1973. The hottest July on record in South Korea was in 1994, when the average temperature reached 27.7 degrees Celsius. In northern Vietnam, 17 places across seven provinces reported record highs for the month of August, with electricity demand spiking as people try to stay cool, authorities said Tuesday. The capital Hanoi experienced its first-ever August day above 40C on Monday. In Japan, some dams and paddies nationwide are experiencing a water shortage, with farmers complaining that the sizzling heat combined with a lack of rain is slowing rice cultivation. Precipitation in July was low over wide areas of Japan, with northern regions facing the Sea of Japan experiencing record low rainfall, it added. The rainy season ended about three weeks earlier than usual in western regions of Japan, another record. Every summer, Japanese officials urge the public to seek shelter in air-conditioned rooms to avoid heatstroke. The elderly in Japan -- which has the world's second-oldest population after Monaco -- are particularly at risk. This year, western Europe saw its hottest June on record, as extreme temperatures blasted the region in punishing back-to-back heatwaves, according to the EU climate monitor Copernicus. Dangerous weather stretched into the next month, with separate research estimating that climate change made the temperature up to 4C hotter, pushing the thermometer into deadly territory for thousands of vulnerable people and greatly worsening the projected death toll. Firefighters also battled blazes across Turkey, Bulgaria, Greece and Portugal in July following a deadly heatwave. Millions were exposed to high heat stress as daily average temperatures in western Europe climbed to levels rarely seen before -- and never so early in the summer. - AFP

Japan hits record 41.8°C as heat threatens rice crops
TOKYO: Japan registered its highest temperature on record at 41.8 degrees Celsius (107.2°F) on Tuesday, with authorities urging residents to stay indoors and warning of potential harm to rice crops. The eastern city of Isesaki in Gunma prefecture surpassed the previous record of 41.2°C set last week in Tamba, Hyogo prefecture, according to the meteorological agency. More than 53,000 people have been hospitalized for heatstroke this summer, the Fire and Disaster Management Agency reported. 'Today is murderously hot,' said Takeshi Ishikawa, a 63-year-old auto worker in Tokyo. 'If it gets to 42 degrees, it would be hotter than my bath that I prepare at 40 degrees.' Japan's average temperatures have risen steadily, with July marking the third consecutive year of record highs. Meanwhile, the northeastern region near the Sea of Japan faces critically low rainfall, worsening fears over rice yields. Rising heat has also led to increased stink bug infestations in rice-growing areas. Farm Minister Shinjiro Koizumi stressed the urgency of addressing heat-related damage. 'We need to act with speed and a sense of crisis to prevent damage,' he said, announcing government support for pest control and drought measures. Last year's extreme heat severely impacted rice quality, causing shortages and soaring prices. - Reuters
