Pacific Drought Summary

The week was drier than normal in Hawaii. The depiction was unchanged in Hawaii.

The week was drier than normal in most of Alaska, with wetter-than-normal conditions in the Alaska panhandle. Alaska remained free of drought and abnormal dryness.

The Republic of Palau was free of dry conditions and received 3.24 inches at Palau IAP and 2.03 inches at Koror COOP.

The Mariana Islands also remained free of dryness. Rainfall at all locations exceeded the 1-inch weekly minimum to satisfy water needs. Guam and Rota received 4.54 inches and 3.82 inches, respectively. Saipan rain amounts ranged from 2.60 inches to 3.27 inches.

The Federal States of Micronesia were largely free of drought, apart from Kapingamarangi, which was entering its second week of extreme (D3) drought. A report from Kapingamarangi via WSO Pohnpei indicated that recent rainfall helped catchment tank levels. The community water tanks were nearly 100% full and private (personal) water tanks were around 50% full. Vegetation was still stressed and yellowing.

Several other locations in Micronesia had 2 inches or more, which is adequate for weekly water needs. Chuuk received 3.23 inches; Pingelap, 4.41 inches; and Pohnpei, 4.34 inches. A few other locations, like Fananu, Kosrae, Lukunor, Nukuoro, Ulithi, and Yap received less than 2 inches, but received enough rainfall in previous weeks that water supplies should not yet be a concern. Woleai had 4 days’ worth of data missing, so this location was set to no data for the week, although adequate rain in recent weeks should mean that there is enough water to meet needs.

The Marshall Islands continued to be wet with most locations receiving more than 2 inches of rain, or enough to satisfy weekly water needs. Ailinglaplap reported 8.12 inches and Mili got 4.63 inches, while other locations received more than 2 inches. The Majuro reservoir, which has a maximum capacity of 36 million gallons, held 27,314 million gallons on Nov. 29.

American Samoa remained free of dry conditions. Rainfall for Pago Pago was 3.40 inches, Siufaga Ridge reported 1.80 inches, and Toa Ridge received 1.62 inches.
