Drought worsens for a portion of Micronesia.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS GUM wrote it up.
Drought worsens for a portion of Micronesia.
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, 9:12 AM UTC, 4 hours 48 minutes earlier.
Area Forecast Discussion National Weather Service Tiyan GU 712 PM ChST Tue May 31 2022 .Marianas Synopsis... Gentle trades, partly cloudy skies and isolated showers are seen across the Marianas. Seas range from 3 to 4 feet across the coastal waters. && .Discussion... Latest models keep moisture on the low side through Thursday, and have reverted to isolated showers through Thursday night. Moisture increases by Friday and the weekend as trade-wind disturbances approach from the east. Friday appears to have the best chance of rain with scattered showers and isolated thunderstorms developing in deep moisture. Beyond that, have maintained 30 pct POPs in variable moisture from Saturday through Tuesday. && .Marine... Winds and waves will both be low, and so will the rip risk starting on Wednesday and persisting the rest of the week. && .Fire weather... Dryness persists, but Monday's showers knocked the KBDI down to 646, and fire conditions are expected to stay below critical levels in very light winds and the expectation of scattered showers later this week. && .Eastern Micronesia... The biggest challenge today was trying to figure out how to delineate POPs (Probability of Precipitation) as the GFS and European (ECMWF) show a decreasing precipitation potential for the middle to end of next week in the precipitation fields, with the GFS showing the GDI dropping to 30 or less during this time (indicative of isolated to low-end scattered showers). This scenario has been well-advertised for days now, and this trend is reflected in the current forecast. Seas will be pretty tame, with combined seas remaining in the 3 to 4 foot range with winds generally 10 knots or less. && .Western Micronesia... Here the precipitation potential was the challenge, but for a different reason. The western extent of the ITCZ that's currently near Chuuk will weaken and lift north temporarily, allowing for just isolated shower potential at best. This changes by the start of next week though, as it settles south back into the region. Farther west for Palau and Yap, the 64,000 dollar question is which model will be right, the GFS or European (Euro). The GFS portrays a surface high setting up to the northwest of the Marianas with its effects stretching down across these two locations, suppressing or at least severely inhibiting shower development. The Euro however has the high pressure well to the east-northeast of the Marianas. This allows for less suppression in the height fields while keeping the brunt of the drier air away from the region, with more of a typical trade wind flow from the east. That said, this model is also less robust in its precipitation fields and this has been a trend within it as well. Given that the euro has a lower grid scale resolution (the distance between two data points in its simulations), the GFS could be onto something. The net result was to decrease POPs in the middle to end of the forecast period, which weren't that spectacular in general. Light seas of 2 to 3 feet and winds of 10 knots or less will dominate your maritime conditions this forecast period, although they could push 4 feet at Chuuk by early next week. && .GUM WATCHES/WARNINGS/ADVISORIES...

1 drought. Local standard time, as filed.
Kapingamarangi entered Severe drought or D2 as only 0.78 inches of rain fell from June 1st to the 22nd. This is the result of the heavier rainfall moving further north.
Water levels for both private and public water tanks are roughly 30% of capacity. Vegetation is turning yellow.
