Rescuers and aid workers in central Vietnam raced to reach isolated area that were battered by floods and landslides, killing at least 37 people, as another typhoon was on track to make landfall later this week, officials said Monday. Days of record rain that began in late October triggered flash floods and landslides that inundated villages, swept away homes and displaced tens of thousands. Meanwhile, Typhoon Kalmaegi is forecast to rapidly strengthen as it heads toward Vietnam’s central coast, with winds potentially reaching up to 166 kph (103 mph) when it enters the South China Sea on Wednesday, after crossing the Philippines, according to Vietnam's National Center for Hydro-Meteorological Forecasting.
