Through Surface weather observation, China and International Red Cross and Red Crescent Movement

In Vietnam, heavy rains accompanied the storm, amounting to over 510 mm (20 in) in some areas, triggered catastrophic and deadly flooding. Widespread structural and agricultural losses took place in addition to the significant loss of life, with damage estimated at ₫300 billion ($71.7 million). In the wake of the flooding, some international aid was sent to Vietnam, though most relief work was conducted by the nation's government, local agencies, and the Red Cross.

Meteorological history

On May 20, following Typhoon Brenda's passage through the South China Sea, a monsoon trough extending from the area into the Bay of Bengal received enhanced low-level southwesterly flow. An environment of weak wind shear in the wake of the typhoon allowed a new area of low pressure to form within the southwesterly flow on May 21. With convection becoming persistent and the system's overall presentation more organized by May 22, the JTWC issued a Tropical Cyclone Formation Alert at 0300 UTC. Around this time, the Japan Meteorological Agency (JMA) classified the system as a tropical depression. Later that day, convection wrapped entirely around the center of circulation; this structural improvement, combined with nearby surface observations, prompted the JTWC to designate the system as Tropical Storm Cecil.

Initially, Cecil was forecast to maintain a northward track into a weakness in a subtropical ridge left behind by Typhoon Brenda; however, Cecil turned westward on May 23 due to another ridge over China. With favorable atmospheric conditions, Cecil continued to intensify through May 24. By 0600 UTC, a ragged 75 km (47 mi) wide eye developed over the center of circulation, indicating it had become a typhoon. The storm ultimately attained peak winds of 140 km/h (87 mph) while situated just off the coast of central Vietnam. However, the JMA reported Cecil to have been slightly weaker, classifying it as a severe tropical storm with ten-minute sustained winds of 110 km/h (68 mph). Around 1800 UTC (just after midnight on May 25, local time), the storm made landfall near Hoi An with winds of 130 km/h (81 mph). Once onshore, Cecil quickly weakened to a tropical depression. Turning slightly to the west-northwest, the remnants of Cecil continued inland before dissipating over eastern Laos early on May 26.
