The entire country received higher precipitation than previous three months during August 2014. In northern and central islands the amount of rainfall received in August is the highest this year. Despite this the total rainfall deficit in this region continues to increase. In southern islands a lower than expected rainfall contributed to an emerging rainfall deficit.
