The National Weather Service in the Northern Marianas has advised residents to conserve water as the drought across Micronesia continues.
It said April had been very dry and computer models indicated below normal rainfall over the next few months.
Aside from warning about an impending water shortage, the forecasters have warned of worsening yellowing of food crops and an increase in grass fires.
Through the first half of April, rainfall on Saipan, Tinian, and Rota was less than 30 percent of the normal fall for the month.
Palau, the Federated States of Micronesia and the Marshall Islands have already made declarations of state of emergencies and disasters.
