Flood alerts spread across London as the River Thames poses a risk in 13 areas due to high spring tides. National security is heightened, with low-lying roads and footpaths potentially flooding for 1-2 hours around high tide, peaking at 4-6 pm and 4 am. Homes are not expected to flood, but concerns arise as the river flow at Teddington Weir reaches 230 cubic meters per second. The identified areas include Custom House, Limehouse, Rotherhithe, Greenwich, Tate Modern, Bow, Putney, Chiswick, Mortlake, Twickenham, Richmond, and areas below Teddington Lock. Authorities stress vigilance as temperatures drop, intensifying flood risks.

A volcano has erupted once again in the southwest peninsula of Iceland, reminiscent of the molten rock spectacle observed just last December. The eruption, which commenced north of the town of Grindavik, prompted an overnight evacuation. This raises critical questions regarding the stability of the region and the effectiveness of existing preventive measures. The recurrence of volcanic activity presents a significant challenge for authorities, especially considering that efforts to mitigate risks from fissures in December now appear inadequate. The eruption's proximity to previous incidents intensifies the need for a comprehensive and efficient strategy to protect vulnerable communities. This unsettling development highlights the relentless and unpredictable nature of Iceland's volcanic landscape, emphasizing the ongoing challenges in managing such geological phenomena.

Volcano near Grindavik, Iceland, erupted for the fifth time in two years, leading to the evacuation of residents due to heightened seismic activity. The Icelandic Meteorological Office reported a crack opening north of Grindavik, prompting evacuation around 3 am. Live images captured dramatic scenes of glowing lava jets against the winter sky. This follows a previous eruption on December 18, necessitating evacuations. Grindavik, with around 4,000 residents, faces recurrent safety measures in this small fishing village. Iceland, boasting 33 active volcano systems, experiences frequent volcanic activity due to its unique geological positioning.

Delhi schools are gearing up to resume physical classes on January 15, following an extended winter break. In response to the prevalent dense fog, authorities have mandated that no classes will commence before 9am or extend beyond 5pm. The decision aims to ensure the safety of students amid the challenging weather conditions. Despite the winter break extension until January 12, the drop in temperature, reaching a minimum of 3.5 degrees Celsius on Sunday, prompted the need for continued precautions. Teaching and non-teaching staff are expected to report for duty as usual. The foggy conditions are anticipated to persist until January 20, according to the India Meteorological Department.

Amid worsening air quality, Delhi-NCR enforces anti-pollution curbs under GRAP-III. The Commission for Air Quality Management reintroduces restrictions, banning non-essential construction, BS-III petrol, and BS-IV diesel vehicles. The central commission advises state governments to consider suspending classes up to Grade 5. The decision follows an emergency meeting due to a sudden deterioration in air quality, with the 24-hour AQI surpassing 400, categorizing it as 'severe.' The 8-point action plan includes increased road cleaning, water sprinkling, public transport enhancement, and stricter bans on construction activities. Measures aim to combat the escalating pollution levels in the region.

After a brief respite, cold wave grips Kashmir as Srinagar records minus 4.2 degrees Celsius, dropping 4.4 degrees from Friday's temperature. The dry winter in Kashmir leads to freezing nights and unusually warmer days, with Srinagar's day temperatures 8 degrees above normal. Jammu experiences colder nights than Srinagar, recording 2.5 degrees Celsius. Chilla-i-Kalan, a 40-day harsh winter period, intensifies cold conditions in the region, with chances of snowfall highest during this period. The valley faces a 79% rainfall deficit for December, and mainly dry weather is forecasted till January 21.

Indonesia's Mount Marapi unleashed another eruption on Sunday, sending smoke and ash 1,300m high. No casualties were reported, but over 100 residents evacuated since the alert level was raised to Level 3 on Wednesday. The eruption's unpredictability, not linked to deep magma movement, poses challenges for forecasts. In early December, a surprise eruption claimed 24 lives. With over 120 active volcanoes, Indonesia remains vulnerable to seismic events due to its position on the Pacific "Ring of Fire." Authorities closely monitor Marapi, home to about 1,400 residents, emphasizing the need for preparedness amid ongoing volcanic activity.

Delhi faces the coldest night of the winter, recording a minimum temperature of 3 degrees Celsius in Aya Nagar. The Meteorological Department issues a red alert due to severe cold and dense fog in Delhi and the National Capital Region (NCR). Minimum temperatures in Lodi Road, Safdarjung, Ridge, and Palam are reported between 3.4 and 5.8 degrees Celsius. Flight operations and trains experience delays. Delhi's Air Quality Index reaches 365, categorized as 'very poor.' Red alerts extend to Punjab, Haryana, and Chandigarh. Yellow alerts for cold and foggy conditions issued in Rajasthan, with the cold wave expected to persist.

Delhi continues to grapple with a severe cold wave as thick fog envelops the city, causing near-zero visibility on roads. Flight and train operations are severely impacted, with 22 trains to Delhi delayed and numerous flights affected at Indira Gandhi International Airport. The minimum temperature plummeted to 6.2 degrees Celsius, and the Indian Meteorological Department predicts worsening conditions till January 16. The CAT III landing system at Delhi's airport is crucial, helping aircraft navigate during dense fog. Passengers are advised to check with airlines. The prevailing cold wave and dense fog continue to grip the National Capital Region, affecting daily life.

Delhi experienced bone-chilling cold on Friday with the mercury plummeting to 3.9 degrees Celsius, marking the lowest temperature this winter. Dense fog blanketed the city, causing zero visibility and disrupting rail and air traffic. The India Meteorological Department (IMD) issued a red alert for Delhi, Punjab, and Haryana, predicting continued severe cold wave conditions until January 15. Several trains faced delays, and a thin layer of fog persisted, reducing visibility to 50 meters in the national capital. The forecast indicates a second consecutive day of below 5 degrees Celsius temperatures, emphasizing the persistence of the intense cold wave.
