The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Guam wrote its last area forecast discussion before the first event at May 31, 7:58 AM UTC, 6 hours 2 minutes earlier.
Area Forecast Discussion National Weather Service Tiyan GU 558 PM CHST TUE MAY 31 2016 .Synopsis... Mostly sunny skies and gentle winds remain in place across the Marianas. Water vapor imagery shows an upper-level trough stretched over Guam with TUTT cells east of the Marianas near 150E and just northwest of Koror. && .Discussion... Subsidence and limited atmospheric moisture today kept weather sunny and dry across the Marianas. Water vapor imagery shows the very dry air over Guam stretching from east to west. Dry weather will remain in place the next few days. The upper-level low to our east will slowly head west this weekend and could produce thunderstorms across the region then. Gentle southeast winds will turn toward the south by the end of the week. GFS model shows a better chance of showers early next week as a surface trough approaches the Marianas. && .Eastern Micronesia... A long SW-NE oriented surface trough stretches through eastern Micronesia from Kosrae to just northeast of Majuro...and this feature will produce most of the significant weather in the region over the next few days. Pohnpei will see only isolated showers the rest of the week...while Kosrae will likely see isolated thunderstorms as well...mainly tonight and again late in the week. Majuro is likely to get the most rain...with scattered showers moving through overnight...then isolated showers and thunderstorms Thu-Fri. Some fairly significant rainfall is possible at Majuro Sat-Sun as scattered showers and thunderstorms may produce locally heavy rain. && .Western Micronesia... An upper-level low is still producing isolated thunderstorms in the vicinity of Palau...and this should persist tonight thru Wednesday night as the low moves away to the northwest. From Thursday on...dry weather will resume at Koror with little rainfall expected Thu-Sun. A dry pattern will also hold for Yap and Chuuk with light winds and no more than isolated mainly light showers. && .GUM Watches/Warnings/Advisories... GU...None. Marianas Waters...None. && M.

5 drought. Local standard time, as filed.
Sufficient rainfall allowed drought conditions to end across Palau by the end of June. 16.25 inches of rain fell at the Koror WSO which is 90 percent of normal.
Showers increased across Yap state, but rainfall was still below average at a few location. Ulithi remained in extreme drought (drought level 3 of 4) with 4.88 inches falling during the month which is only 48 percent of average. On Yap Island the WSO only recorded 49 percent of average totaling only 6.46 inches of rain.
Rainfall across the Marshall Islands improved in some locations, but some areas were still experiencing drought. Utirik remained in exceptional drought (drought level 4 of 4). Only 2.46 inches fell in June which is 50 percent of the average. Jaluit remained in extreme drought (drought level 3 to 4) receiving only 4.32 inches, which is 42 percent of the average.
Majuro saw a little more rainfall with 7.07 inches falling which is 65 percent of average. Water managers on Majuro did an outstanding job of managing the runway reservoir and well-water. Their efforts paid off in that the reservoir became nearly full by mid-month despite the paucity of rainfall.
The Commonwealth of the Northern Marianas, a group of islands north of Guam, recieved less than 50 percent of the average rainfall during the month.|On Rota, only 2.54 inches fell (49 percent of average), TInian 1.63 inches (32 percent|of average) fell, and Saipan saw only 46 percent of it's rain with 2.05 inches falling.|This low rainfall put the CNMI into extreme drought (drought level 3 of 4).
