Climate Outlook: The persistent easterly winds that dominated the flow in eastern Micronesia for the past two years should give way to a more variable wind pattern as El Niño brings the monsoon trough and tropical disturbances into the region. Normal monthly rainfall for Kosrae is typically between 17 and 20 inches for all months of the year. Rainfall for the next few months should be near normal, although month-to-month rainfall variability may become greater as the weather pattern becomes more active. In the final three months of the year, a tropical cyclone may form near Kosrae State bringing heavy rains, gusty southwesterly winds, and rough seas to island waters. Southwesterly winds may bring rough seas to the west and southwest side of the island.
