La Nina is expected to round out the rest of the year. The La Nina setup will maintain a sharp rainfall gradient near Kapingamarangi the next several months with showery weather to the north and drier conditions in the vicinity of Kapinga. Some months are likely to see fairly dry weather with monthly rainfall around 3 to 5 inches while other months see a bit more rain. Overall, rainfall will be well below normal and drought is expected to persist.

These water tanks will bolster water resources once they are installed. .LOCAL DROUGHT OUTLOOK: 1 to 3 inches of rainfall is expected through the end of August with most rainfall occurring during passing trade-wind disturbances. Overall rainfall is expected to be inadequate (less than 8"/month) to meet most water needs the next several months. This is supported by seasonal model guidance and the ongoing La Nina climate pattern. Residents of Kapinga are encouraged to conserve water as the large- scale pattern is not favorable for plentiful rains. .NEXT ISSUANCE DATE: The next Drought Information Statement will be issued Friday, September 2, 2022 or sooner if necessary. .RELATED WEBSITES: -US Drought Monitor for the United States Affiliated Pacific Islands- https://droughtmonitor.unl.edu/CurrentMap/StateDroughtMonitor.aspx?usapi -National Weather Service Guam- https://www.weather.gov/gum/Hydrology -Pacific ENSO Applications Climate (PEAC) Services- https://www.weather.gov/peac -Climate Prediction Center Global Tropics Hazards and Benefits Outlook- https://www.cpc.ncep.noaa.gov/products/precip/CWlink/ghazards/ -Coral reef watch satellite monitoring- https://coralreefwatch.noaa.gov/satellite/index.php .ACKNOWLEDGMENTS: This drought statement is a combined effort involving regional National Weather Service offices, USAPI drought monitor team, Tropical Weather Sciences, the Climate Prediction Center, PEAC Services, the International Research Institute for Climate and Society, USAID subregional offices and the NOAA/NESDIS coral reef watch program. .QUESTIONS OR COMMENTS ABOUT THIS PRODUCT?
