Quarterly Climate Impacts and Outlook for the Pacific Region for September–November 2024. Dated December 2024.

In September–November, above-normal precipitation was observed across much of the U.S.-Affiliated Pacific Islands (USAPI), including in Palau, portions of the Federated States of Micronesia (FSM), the Commonwealth of the Northern Mariana Islands, the Republic of the Marshall Islands, and American Samoa. Conversely, below-normal rainfall was observed in areas closer to the equator in FSM, including in Kapingamarangi, Kosrae, and Lukunor.

Regional groundwater measurements in the Ogallala Aquifer show ongoing declines in aquifer water quality and quantity that are being exacerbated by warming trends and highly variable precipitation. The importance of this system, which is used for agriculture and is a main driver impacting socioeconomic activity and ecosystems in the region, cannot be overstated. Addressing regional aquifer depletion and other water-related challenges, including drought, is vital and necessary work.
