Drought continues in a few locations in 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 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 Jun 30, 7:54 AM UTC, 6 hours 6 minutes earlier.
Area Forecast Discussion National Weather Service Tiyan GU 554 PM ChST Tue Jun 30 2020 .Marianas Synopsis... Satellite imagery and the latest 'working' radar shows showers and thunderstorms well to the north of Saipan associated with an upper low and another set of scattered showers and isolated thunderstorms well south of Guam associated with a weak tropical disturbance. Otherwise, mostly dry conditions have prevailed over the southern Marianas Islands today. Still might expect another shower or two in the Saipan/Tinian coastal waters overnight. Winds at the airports are easterly at 10 to 15 kt and the buoys are seeing only 3 to 4 feet of combined seas. && .Discussion... Not too many features of interest over the Marianas with most of the action south of 10N. The upper low north of the islands appears to be shrinking as it wiggles north. I still kept the possibility of a shower or two, with thunderstorms, for Saipan and Tinian for tonight with the upper divergence and instability still present. Tomorrow's forecast is more problematic with the passing disturbance well to the south between Yap and Chuuk. The models suggested a brief period of instability over the islands during the daytime is possible. Afterwards, the upper divergence weakens and the disturbance pushes more to the west leaving mostly isolated showers for the rest of the week. I kept the forecast as is, for the possibility of thunderstorms on Friday and Saturday in tune with the proximity of the westward moving upper low currently near Wake Island. && .Marine... WW3 global wave model shows no significant swells with periods greater than 8 seconds through most of the week. Altimetry shows mostly 4 feet everywhere, but I gave in to the possibility that a spark in the trades may push the wind waves tomorrow up to 5 to 6 feet before dropping down again. WW3 suggests the possibility of bringing the surf down to 4 feet on the east side on Friday and Saturday which would reduce the risk of dangerous rip currents down to low. && .Eastern Micronesia... In the east, satellite shows a tropical disturbance west of Pohnpei, moving west. In its wake, gentle trade winds will maintain a fairly dry regime the rest of the week for Pohnpei and Kosrae with isolated showers, accompanied by isolated thunderstorms at times. But in the Marshall Islands, GFS amplifies a trade-wind trough near Majuro into a weak circulation overnight that passes just south of Majuro on Wednesday before opening into a trough again by Thur evening. This is expected to bring scattered showers and isolated thunderstorms to Majuro Wednesday and Wednesday night, followed by a return to drier weather the rest of the week. Seas across the region are expected to be mainly 3 to 4 feet through Sunday. && .Western Micronesia... A pair of tropical disturbances is seen on satellite imagery in western Micronesia this evening. Number 1 is over Chuuk, having departed Pohnpei earlier in the day, and Number 2 is approaching Yap and Palau. Number 1 is expected to bring scattered showers and isolated thunderstorms to Chuuk this evening, while Number 2 does the same for Yap while bringing scattered showers and thunderstorms through the night to Palau. Chuuk should see only isolated showers, with isolated thunderstorms at times, the rest of the week. But then disturbance Number 1 is forecast to move west and push scattered showers and thunderstorms through Yap Wednesday night, and into Palau for Thursday and Friday. Except for some 5-foot seas in Chuuk waters tonight and Wednesday morning, seas around 3 or 4 feet are expected through Sunday. && .GUM WATCHES/WARNINGS/ADVISORIES... GU...None. Marianas Waters...None. && Edson/Middlebrooke
