A powerful winter storm has swept across the US Midwest, bringing over a foot of snow and causing major disruptions from South Dakota to New York. More than 53 million people were under winter weather alerts as heavy snow, strong winds, and thunderstorms created hazardous conditions. Des Moines recorded 10.9 inches (28 cm) of snow by midnight Sunday, marking its heaviest two-day snowfall since January 2024. Chicago’s O’Hare International Airport saw 8.4 inches of snow on Saturday, setting a new November snowfall record for the city. Illinois State Police reported around 500 vehicle accidents in the Chicago area on Saturday alone. Authorities have urged residents to avoid unnecessary travel as cleanup and recovery efforts continue amid freezing temperatures and ongoing weather warnings.

Bangladesh’s Fisheries and Livestock Adviser Farida Akhter has warned that marine fish stocks in the Bay of Bengal are rapidly declining due to illegal, unregulated, and excessive fishing, as well as the use of harmful nets. Speaking at the debriefing of the Ecosystem Approach to Fisheries (EAF)-Nansen Survey 2025 in Dhaka, she said the recent R.V. Dr. Fridtjof Nansen survey results highlight an alarming depletion of fish resources. The survey found oxygen-depleted zones, high microplastic concentrations, and abnormal jellyfish proliferation, signaling severe ecological stress. Akhter urged stricter control over industrial trawler licensing and called for scientific planning to ensure sustainable deep-sea fishing. The survey, conducted from August 21 to September 21, 2025, identified 65 new fish species, including five unique to the Bay of Bengal. Officials from Norway, FAO, and Bangladesh emphasized continued international cooperation and the need for Bangladesh to acquire its own research vessel to strengthen marine resource management and biodiversity conservation.

In Bangladesh’s Chalan Beel region, widespread snail collection has raised serious environmental concerns as local farmers and fishers, facing seasonal unemployment, harvest snails for sale to traders who supply them as feed for ducks and fish. The trade, reportedly worth around 50,000 taka daily at Bilsha point alone, has become a major source of income for marginalized communities. However, environmental experts warn that snails play a crucial ecological role by cleaning water bodies and maintaining soil fertility. Their indiscriminate removal could lead to water pollution, reduced fish production, and declining soil quality. Despite existing laws protecting aquatic species, enforcement remains weak, allowing the practice to continue unchecked. Local biodiversity activists have urged administrative intervention, while agricultural officials caution that the loss of snails and other aquatic organisms could reduce calcium levels in the soil, ultimately affecting crop yields. The local administration has pledged to investigate and take legal action against those involved.

In a rare and astonishing event in the deep Bay of Bengal, around three maunds of hilsa fish reportedly jumped directly onto a cargo vessel without the use of nets. The incident occurred about 70 kilometers off the coast near the first buoy of the Rabnabad Channel at Payra Port in Patuakhali. Crew members of the coal-carrying vessel MV KSL Gladiator witnessed the unusual phenomenon as schools of small hilsa suddenly leapt from the sea onto the ship’s deck, resembling a silvery rain. Ship engineer Robiul Hossain captured a short video of the event and shared it with journalists. Marine science expert Dr. Rajib Sarkar from Patuakhali Science and Technology University explained that the behavior might have been triggered by predatory fish chasing the hilsa, combined with the ship’s lights, vibrations, and propeller noise, which could have disoriented the fish and caused them to leap upwards. The sailors described the experience as a once-in-a-lifetime sight.

India has issued a red alert for Tamil Nadu, Andhra Pradesh, and the Union Territory of Puducherry as Cyclone Ditwa moves rapidly toward the southeastern coast. The India Meteorological Department (IMD) reported that the cyclone is expected to pass near the northern Tamil Nadu, Puducherry, and southern Andhra Pradesh coasts on Sunday. Chennai airport authorities have canceled 54 flights as a precaution. Wind speeds are reaching 70–80 km/h, with gusts up to 90 km/h, and heavy rainfall has already affected the region. IMD officials warned of possible flooding in low-lying areas and advised residents to stay indoors. Fishermen have been instructed not to venture into the sea. While major damage is not anticipated, agricultural fields may suffer losses. The Tamil Nadu government stated that it is fully prepared to handle any emergency situation arising from the cyclone’s impact.

Severe monsoon rains, floods, and landslides have killed more than 600 people across South and Southeast Asia, with hundreds still missing. Indonesia, Malaysia, Thailand, and Sri Lanka are among the worst affected countries. Indonesia’s Sumatra island alone reported over 300 deaths after days of heavy rainfall, while Thailand’s southern provinces saw at least 160 fatalities in one of the worst floods in decades. Sri Lanka, battered by Cyclone Ditwahar, has declared a state of emergency after more than 130 deaths and 170 missing persons. Malaysia’s northern regions also reported casualties and mass evacuations. Meteorologists attribute the extreme weather to the combined effects of Typhoon Koto near the Philippines and the rare Cyclone Seniyar in the Malacca Strait. Millions have been displaced, infrastructure severely damaged, and rescue operations hampered by ongoing bad weather across the region.

After a long suspension, ship operations on the Cox’s Bazar–Saint Martin’s route will resume on December 1, allowing tourists to stay overnight on the island under 12 strict government guidelines. A maximum of 2,000 tourists per day will be permitted to visit, with four vessels—MV Karnaphuli Express, MV Baro Aulia, Keari Sindbad, and Keari Cruise & Dine—authorized to operate. The district administration and environment department will enforce the new rules to protect the island’s fragile ecosystem. Tourists must buy tickets online through an approved tourism portal containing a QR code for verification. Activities such as beach lighting, loud music, barbecues, and the use of motorized vehicles or single-use plastics are prohibited. Overnight stays will be allowed only in December and January, while February will remain closed to visitors. Authorities hope the new measures will ensure sustainable and eco-friendly tourism while preserving Saint Martin’s unique biodiversity.

Bangladesh faces a severe earthquake threat due to the Ganges-Brahmaputra megathrust fault, which could trigger a magnitude 9 quake, experts warned at a seminar in Dhaka organized by JCX Developments Limited. Local and international geologists, architects, and engineers highlighted that the country lies at the junction of three active tectonic plates—Indian, Myanmar, and Eurasian—making it highly vulnerable. Over 200 earthquakes have been recorded in the past century, with increased activity since 2024. Specialists emphasized that the accumulated energy in the subduction zone from Sylhet to Teknaf remains unreleased for nearly a millennium. Japanese experts shared lessons from Japan’s earthquake-resistant architecture and urged stronger building codes, structural audits, and emergency preparedness. Participants called for coordinated efforts between government and private sectors to build resilience through awareness, drills, and technological readiness. Rapid urbanization, dense population, and weak infrastructure were identified as major risk factors that could worsen the impact of a major quake.

Sri Lanka has declared a nationwide state of emergency after relentless rains caused by Cyclone Ditwah led to catastrophic flooding across the island. At least 132 people have died and 176 remain missing, according to the Disaster Management Centre (DMC). More than 15,000 homes have been destroyed, and over 78,000 residents have been relocated to emergency shelters. The military, navy, and air force are conducting joint rescue operations, including a 24-hour mission in Anuradhapura that saved 69 passengers, among them a German tourist. Central districts such as Badulla and Kandy have been severely affected, with roads and bridges washed away, isolating many villages. Power and water supplies have been disrupted in about one-third of the country, and communication networks remain unstable. President Anura Kumara Dissanayake’s government has appealed for international assistance and urged Sri Lankans abroad to send financial aid. Meanwhile, Cyclone Ditwah is moving north toward India, prompting flight cancellations in Chennai and warnings of heavy rain and strong winds.

An endangered Palash fish eagle was rescued by the Forest Department in Satkania, Chattogram, after it was found injured from an electric shock. The bird reportedly came into contact with a high-voltage power line while flying over a pond in the Uttar Chadaha area on Saturday morning, causing it to fall into the water. Locals promptly informed forest officials, who arrived at the scene and rescued the eagle. The injured bird was later transferred to Dulahazara Safari Park in Cox’s Bazar for medical treatment. According to Chunati Wildlife Sanctuary Beat Officer Chanchal Kumar Tarafdar, the Palash fish eagle is a large brown sea eagle species that primarily hunts aquatic fish and is identifiable by a distinctive white band on its tail. The species is considered endangered in Bangladesh and plays a vital role in maintaining the country’s ecological balance and biodiversity.

Cyclone Ditwah has caused severe devastation in Sri Lanka, leaving at least 123 people dead and 130 missing as it moves north-northwest over the southwestern Bay of Bengal. The Bangladesh Meteorological Department has issued distant warning signal No. 2 for the country’s four major seaports—Chattogram, Cox’s Bazar, Mongla, and Payra—advising all fishing boats and trawlers to remain near the coast and avoid deep-sea operations until further notice. As of Saturday morning, the cyclone was located about 1,880 kilometers southwest of Chattogram and 1,750 kilometers southwest of Mongla. Winds near the cyclone’s center are reaching sustained speeds of 62 km/h, with gusts up to 88 km/h, making the sea very rough. Sri Lanka continues to experience heavy rainfall exceeding 300 millimeters in some areas, along with strong winds and flooding. Regional authorities are monitoring the storm’s movement closely as it continues to track toward the northern Bay of Bengal.

At least 56 people have been killed and 21 remain missing after Cyclone Ditwah struck Sri Lanka, triggering severe flooding and landslides across the island. Heavy rainfall exceeding 300 millimeters in several regions has caused widespread destruction, particularly in the eastern and central districts. The Disaster Management Centre (DMC) reported that 21 people died in a landslide in the tea-producing district of Badulla. Over 44,000 people have been affected nationwide, with homes destroyed and many residents stranded. Schools, colleges, and universities have been closed, and several international flights have been canceled. Authorities have issued a red alert for low-lying areas along the Kelani River, including parts of the capital Colombo, urging residents to move to higher ground. Rescue operations are ongoing, though access to remote areas remains difficult due to continuous heavy rain and damaged infrastructure.

Severe floods and landslides have claimed more than 300 lives across Indonesia and Thailand, with both nations struggling to recover from the widespread destruction. In Indonesia’s Sumatra region, at least 174 people have died and 80 remain missing after torrential rains triggered flash floods and landslides. North Sumatra alone reported 116 deaths, while Aceh and West Sumatra recorded 35 and 23 fatalities respectively. Rescue efforts continue as many areas remain cut off and power restoration is underway. In Thailand, southern provinces have been hit by record rainfall, leaving at least 145 people dead, including over 110 in Songkhla province. Thousands have been displaced, and authorities are accelerating search and recovery operations as floodwaters begin to recede. Despite some improvement in weather conditions, the Thai Meteorological Department has warned of possible thunderstorms in several southern regions, raising concerns about further hazards.

At least 84 people have been killed and dozens remain missing after severe floods and landslides struck Indonesia’s Sumatra island this week. Rescue teams confirmed the toll on Friday, with North Sumatra province reporting 62 deaths and 95 injuries, while West Sumatra recorded 22 deaths and 12 missing persons. The city of Sibolga has been among the hardest hit, with over 30 fatalities. Ongoing heavy rains have hampered rescue operations, cutting off access to several areas. Authorities are focusing on evacuating residents and delivering relief supplies, though poor weather and damaged infrastructure have slowed progress. In Aceh province, about 1,500 people have been displaced and power outages reported after flooding and landslides. Indonesia’s state electricity company is working to restore power after a transmission tower collapse. Experts warn that climate change is intensifying monsoon storms, prolonging rainy seasons, and increasing the frequency of flash floods across the region.

Cyclone Ditwah, currently positioned over the southwest Bay of Bengal and adjacent to the Sri Lankan coast, is moving in a north-northwesterly direction, according to a special bulletin issued by the Bangladesh Meteorological Department on Friday morning.
