Summary: Over recent days, Typhoon Kalmaegi has caused widespread destruction across the Philippines and Vietnam as it moved through Southeast Asia. As of 07 November, the storm has caused over 180 casualties in the Philippines and five casualties in Vietnam. The storm has triggered mudslides, landslides, and flooding in multiple regions, leading to the evacuation of thousands of people. Both countries typically experience several storms each year. Additionally, scientists warn that global warming has contributed to the increased frequency and intensity of storms across Southeast Asia.
Implications:
- Philippines: Heavy rainfall from Typhoon Kalmaegi caused mudslides and flooding in various parts of the country. The storm particularly impacted central regions, including Cebu, forcing thousands of residents to evacuate. More than 560,000 people were reportedly displaced. A state of calamity was declared nationwide on 06 November to expedite emergency funds, procurement, and the delivery of essential goods and services. Following Typhoon Kalmaegi, another storm, Fung-wong, is moving towards the Philippines and could impact Aurora province and areas around Manila.
- Vietnam: The storm made landfall on 07 November in Dak Lak province, bringing heavy rainfall and strong winds. The typhoon is expected to worsen conditions in central Vietnam, which has already been affected by record rainfall over the past week. The military has deployed more than 260,000 soldiers and personnel for relief efforts. Over 500,000 people were evacuated. Airports and expressways were closed, causing major transport disruptions. Heavy rainfall is expected to cause high tides on the Saigon River, which could lead to flooding in low-lying areas, including Ho Chi Minh City.
Outlook: Typhoon Kalmaegi has weakened into a low-pressure area and is forecast to move west towards Cambodia and Laos before later impacting northeast Thailand. Moderate to heavy rainfall is expected to continue in parts of Vietnam until 11 November. Thailand’s meteorological department has forecast increased rainfall across upper Thailand from 07 November to 09 November. Persistent rainfall could lead to flash floods and mudslides, especially in mountainous areas, floodplains, and regions near waterways. Damage to utility infrastructure may cause disruptions to power supply and communication services. Transport disruptions are expected to persist across affected regions. Organizations are advised to remain situationally aware and prepare necessary contingency plans.
