ENSO (the EI Nino Southern Oscillation) will return the country at its first level of El Nino by June or July.
If ENSO changes to El Nino at the last three months of this year, the number of tropical low pressure and typhoon hitting East Sea will be more than annual year. However, the volume of tropical low pressure and storm hitting the mainland may be less than every year. 
Flooding season in local rivers of the Central Highlands and Mekong upstream river will appear earlier than every year.
