A new study reveals that human interventions like embankments and lake reclamation along the Yangtze River inadvertently amplified climate-driven flood risks during the Little Ice Age and beyond.
China's top flood control body held an emergency inter-agency meeting to coordinate disaster prevention for an expected 12th named storm, as widespread intense rainfall and saturated soil increase the risk of flash floods and landslides nationwide.
A small Texas town, Presidio, is suing the Trump administration over its plan to build a border wall through a levee system, arguing it could cause flooding and that the government is not following legal requirements. A federal court hearing addressed the dispute, with a ruling expected soon.
A new international study published in Nature reveals that human-driven sea-level rise has quadrupled the frequency of extreme coastal flooding events globally since 1900. The research, based on over a century of tide gauge observations and climate models, highlights a fundamental long-term shift, making even ordinary tides and storms capable of causing damage that once required exceptional conditions. This necessitates a rethink of flood risk planning in coastal communities.
Flood-affected properties in New Zealand are increasing in value faster than undamaged ones, as buyers prioritize affordability despite rising weather risks. Data from Cotality indicates these homes trade at an initial discount but show stronger growth, particularly in regions like Auckland and Hawke's Bay.
Expert Xu Xiaofeng warns Northwest China's arid ecosystems and infrastructure are at higher risk of flood damage due to limited water absorption capacity. Facilities in Xinjiang's desert and Gobi are particularly vulnerable.
Historic floods in Michigan highlight flaws in FEMA's flood plain maps, which often don't cover less-populated areas or account for rainfall-driven flooding, leaving many homeowners uninsured and at risk due to climate change.
Tokyo's Chofu City issued an evacuation order at 8:40 AM on the 3rd for residents in the Noga River basin, citing a risk of flooding and inundation. This corresponds to Level 4 on the five-tier alert system, urging all residents to evacuate from dangerous areas.
Saudi Arabia's Civil Defense has issued a warning for thunderstorms, heavy rainfall, and flash floods expected to persist across much of the Kingdom through Tuesday. The National Center for Meteorology forecasts moderate to heavy thunderstorms affecting Riyadh, Makkah, Madinah, Qassim, Hail, Eastern Province, Northern Borders, Al-Jouf, Al-Baha, Asir, and Jazan, with Makkah and Riyadh facing heightened risk of intense rainfall events. The conditions are linked to a seasonal transition period typical of spring in the Arabian Peninsula.
Hong Kong has launched an AI-driven flood forecasting system with 3D simulation capabilities, developed with South China University of Technology. The system integrates big data and meteorological data to provide real-time flood simulations, replacing static risk maps from the previous visualization system deployed during Super Typhoon Ragasa.
