No changes occurred in Alaska this week.
Hawaii, recent wetter conditions allowed for additional reduction of abnormally dry conditions in central areas of the Big Island.
Heavy to excessive precipitation during the past few months was exacerbated by Super Typhoon Sinlaku, which tracked slowly across the Marianas into April 15. The center moved across the northern Marianas near Saipan, but wind gusts topped hurricane force throughout the island chain. Saipan reported wind gusts reaching 130 mph while Guam – well south of the center – recorded an 87 mph wind gust. Rainfall was intense, especially across the southern reaches of the island near Guam, which reported amounts of over one foot through mid-afternoon April 15. Saipan reported 5.73 inches through April 14, with the storm in progress. These amounts pushed March 1 – April 15 totals to near or above the record for the period. Guam recorded 28.46 inches during these 1.5 months (the normal is 4.36 inches) and Saipan measured 20.59 inches (normal 3.15 inches). Saipan reported 41.46 inches for the year to date (normal 9.30 inches) and Guam has received over 50 inches of rain since December 2025 (normal under 20 inches). It may go without saying that no dryness or drought is noted anywhere across the Marianas, and there is little chance of any developing in the near future.
In Palau, April is off to a dry start, with April 1-13 totals at Koror totaling just over one-half inch (two days of reports were missing). The prior couple of months, however, were at least somewhat wetter than normal, with February bringing almost 11 inches and March bringing slightly more. These amounts were more than sufficient to keep up with water demand, so no dryness or drought is indicated this week, but the situation will need to be monitored if April continues to be very dry.
April is also off to a very dry start in western sections of the Federated States of Micronesia (FSM). Less than one-half inch fell on Yap through the 13th (just 15 percent of normal) and under 0.9 inch was recorded in Ulithi (under 40 percent of normal). However, the first three months of the year were near or wetter than normal, so no impactful dryness or drought is noted at this time. Yap reported over 10.5 inches of rain in January (145 percent of normal), followed by 6.71 inches in February (112 percent of normal) and 6.92 inches in March (over 130 percent of normal).
In the central FSM from Chuuk southward to Kapingamaringi, Lukunor remains abnormally dry this week (D0) while no dryness or drought is noted elsewhere. Lukunor recorded 60 to 75 percent of normal for each of the first three months of 2026, and so far this April, 3.58 inches has been reported, or just under 70 percent of normal. Year-to-date, Lukunor reports 22.37 inches of rain, compared to the normal around 34.6 inches, which supports the D0 designation. This is slightly less than necessary to keep up with demand over the long-term, although serious water shortages have not been reported to date (also, several days of data are missing). To the south, Nukuoro and Kapingamaringi have reported under half of normal rainfall so far this April (3.56 and 2.48 inches, respectively). However, Kapingamaringi recorded more than enough rainfall to keep up with demand during the first 3 months of the year (over 28 inches). In Nukuoro, March (8.49 inches) was considerably drier than normal, but wet enough to keep up with demand. This followed almost 20 inches of rain in February, so no dryness or drought designations are posted for these two locations. North of Lukunor, it has been much wetter at Chuuk, where no drought or dryness designation exists. April totals to date are approaching 14 inches (more than twice normal), and this follows near 11 inches or more each of the three prior months in 2026.
Pohnpei is the only location reliably reporting precipitation recently, and April there has been exceedingly wet. Almost 14 inches of rain fell during the week, bringing month-to-date totals to nearly 25 inches no even halfway through the month. As a result, no dryness or drought designation is assessed, and none is anticipated in the near future.
The northeastern Republic of the Marshall Islands (RMI) was the only area across the U.S. Affiliated Pacific Islands (USAPI) reporting drought last week (April 6). Utirik was in severe drought (D2) while moderate drought (D1) was posted at Wotje. However, rainfall has increased dramatically since late March, and this trend continued through the past week. During March 22 – April 13 at Utirik, 16.70 inches of rain was reported, including 8.27 inches during the last half of this past week. Wotje recorded lesser amounts (7.57 inches) since March 20, which included almost 3 inches this past week. These amounts have dramatically improved conditions over the past three weeks, and both locations are designated as abnormally dry (D0) this week. This represents a 2-category improvement at Utirik. To the west, Kwajalein has received more consistent rainfall over the past few months, and no dryness or drought is impacting the region at this time. Just under 2.5 inches last week brought April-to-date totals to near 4.9 inches and year-to-date amounts to over 23.5 inches, the latter amount considerably more than the normal of about 16.5 inches for the period.
Farther south, the central and southern RMI (Ailinglapalap, Jaluit, Majuro, and Mili) is free from dryness and drought. Last week, rainfall totals ranged from 1.23 inches at Ailinglapalap to 2.38 inches at Mili. April totals to date are near or above normal across Ailinglapalap (3.97 inches, 136 percent of normal) and Majuro (4.86 inches, 116 percent of normal), and amounts over the past 30 days exceeded 18 inches in Mili. This followed robust February – March rainfall at Ailinglapalap (27.85 inches, about 2.5 times normal) and near-normal rainfall during January – March at Majuro. Jaluit was the only site reporting subnormal April rainfall to date (2.71 inches, 57 percent of normal) after near-normal amounts last week. But this followed February – March totals exceeding 20 inches.
So far this year, American Samoa has seen alternating dry and wet periods. Currently no dryness or drought designation is supported, but April to date has been quite dry (1.9 inches, under 40 percent of normal) and February amounts were also unfavorably low (5.1 inches, about 40 percent of normal). In between, however, March brought near normal amounts just shy of one foot, and earlier in the year, January brought nearly 28 inches of rain (almost twice normal).
