As a result, the local population has been advised to "be prepared and store water" by the department.
"El Nino means extreme below normal rainfall for Vanuatu," VMGD's principal scientific officer Glenda Pakoa said.
"That means we might expect drier conditions for the next few months, and drier conditions can lead to water shortages and food shortages," she said.
"I would like to advise communities to make use of our wet season, store water, do not play around with water, especially farmers who plant crops that are resistant to drought events."
