Invest 91W “Closed”…Heightened Regional Weather Activity Still Possible

Friday, May 1, 2026, Valid at 1:30 PM ChST

>>GUAM/CNMI: FAIR WEATHER TO PERSIST ACROSS THE MARIANAS INTO NEXT WEEK

>>CHUUK/POHNPEI/KOSRAE: AREAS OF SHOWERS, T-STORMS & BRIEF GUSTY WINDS THROUGH WEEKEND

REGIONAL WEATHER:

A seasonably dry pattern in place across the Marianas this afternoon will continue through the weekend and into early next week. Expect moderate to fresh trades, with abundant sunshine and spotty showers. Trade winds will keep combined seas elevated the next few days, around 5 to 8 feet, with a moderate risk of rip currents and surf up to between 7 and 8 feet along north and east facing reefs and beaches. Across Micronesia, showers and thunderstorms prevail across Chuuk, Pohnpei and Kosrae States, and eastward toward Majuro and the Date Line. Fresh east-northeast trades are found along and north of 7N, while lighter, variable winds are found across most of the main islands of Micronesia. To the south, a cross-equatorial wind flow is setting up, with southeast to southwest winds converging northward into the FSM. The converging winds, surface troughs and weak, embedded circulations will maintain a showery pattern through the weekend. Brief gusty winds and locally heavy rainfall are possible.

TC POTENTIAL/THREATS:

Tropical cyclone (TC) development remains a possibility in the region through the coming week. However, this is still not a guarantee. Global numerical models still favor TC development in a number of long range scenarios (beyond 5-7 days), originating from one disturbance or another, out of eastern Micronesia. As discussed this week, we’ve watched Invest 91W come and go (the Joint Typhoon Warning Center closed 91W yesterday), and we anticipate another disturbance to possibly take shape in the coming days. Until then, any TCs depicted in a variety of long-range model forecasts remain speculative and subject to high uncertainty. If and when a disturbance begins to materialize, we’ll have improved forecast resolution, as well as increased clarity on the potential for a tropical cyclone.

ACTIONS TO TAKE:

For the MARIANAS: Consider business as normal as we head into the weekend. Any potential TC threat for us in the coming week remains speculative. We need to first see a developing tropical disturbance at the surface in the FSM. This could happen overnight, this weekend, or Monday…and in some cases, not at all. For those across MICRONESIA: Keep up to date with regional forecasts and conditions as the unsettled weather pattern will keep areas of showers, thunderstorms and gusty winds in place the next few days.

For all residents across the western North Pacific: we always urge folks to keep up to date with the latest regional weather forecasts and conditions from the NWS Guam at www.weather.gov/gum, and to maintain a general state of preparedness for any disaster, year round.

4:30 AM, THU, APRIL 30, 2026 - TROPICAL DISTURBANCE, INVEST 91W, REMAINS WEAK AS IT DRIFTS WEST-NORTHWESTWARD

4:30 AM, THU, APRIL 30, 2026 - TROPICAL DISTURBANCE, INVEST 91W, REMAINS WEAK AS IT DRIFTS WEST-NORTHWESTWARD

Invest 91W remains very weak and disorganized. Trends over the last 12 hours show Invest 91W weakening at this time. The latest position from JTWC is 6.7N, 154.0E and the general movement is to the west-northwest. Scattered to numerous showers are seen across portions of Pohnpei and Chuuk States. At this time, little to no development is expected of Invest 91W over the next few days.

We are also tracking seasonal disturbances east of Invest 91W, northeast of Pohnpei and Kwajalein. These disturbances remain below invest level, but could further develop into more organized system. Overall, we are seeing a broader region for potential development with no specific entity that can be pointed towards development. For the time being, some of the ingredients needed for development have not occurred yet, like a more coherent low pressure area (LPA) or broader westerly winds along the equator. Some guidance points towards more westerly winds occurring next week, but these will take some time to develop. This keeps a wide array of solutions possible and uncertainty high. At this time, we are still watching for the potential of TC development over the next 7 to 10 days across portions of eastern or central Micronesia. Model guidance continues to vary significantly with little consensus. The NWS will continue to monitor for these developments.

Folks across eastern and central Micronesia should be prepared for periods of heavy showers and strong gusty winds. Stay tuned for the potential of a strengthening circulation in the coming week.

Folks across western Micronesia and the Marianas should continue monitoring the situation. At this time, we are looking at a general pattern change from the dry conditions that have been present to wetter conditions next week.

Continue to monitor the latest forecast information from weather.gov/gum and for releases from local emergency managers. At the moment, no other actions are needed other than being aware of the current situation.

Weekly Regional Weather Outlook
Tuesday, April 28, 2026, Valid at 3:21 PM ChST

REGIONAL OVERVIEW:

Fair weather with dry and breezy trades will persist across Guam and the CNMI today, through the end of the week, and likely through the weekend. To the southwest, a surface trough is generating showers and thunderstorms near Yap Proper and just east of Palau. This will bring much-needed showers to the Republic of Palau tonight and the next couple of days. A wetter pattern could also linger across parts, or much, of Yap State. Farther east, fair weather prevails across Chuuk State, north of 5N, but showers and thunderstorms are found across much of the region to the south and east, including Pohnpei and Kosrae States, and the Marshall Islands. A series of surface troughs and weak tropical disturbances will keep a showery/unsettled pattern in place across this region through the weekend.

REGIONAL WEATHER FORECASTS :

For the full-text forecasts for: GUAM & CNMI, YAP & PALAU, and CHUUK, POHNPEI, KOSRAE & MAJURO, please visit NWS Guam on the web at weather.gov/gum/publicforecasts. Larger trade wind swell across the Marianas will generate a high risk of rip currents across Guam and the CNMI through Thursday along east-facing reefs and beaches. Also, be advised: headlines have been added to the forecasts for Pohnpei, Kosrae and Majuro for localized heavy rainfall and gusty winds possible through the next several days.

TC POTENTIAL/HAZARDS:

Significant uncertainty remains surrounding possible tropical cyclone development within the region through the next week or two. We are watching a weak tropical disturbance, Invest 91W, in eastern Micronesia, currently centered south of Kosrae and Pohnpei. The Joint Typhoon Warning Center maintains a rating of “sub low” for development with Invest 91W. This means that development is not expected in the next couple of days.

Forecast models maintain a wide range of possible solutions in the longer range (beyond 5 days) regarding development of 91W, or perhaps another disturbance. 91W very well could dissipate, giving way to another circulation in the general vicinity that could eventually take shape and develop. These are some of the many uncertainties still present at this early stage.

For next week, focus should not be placed on any single forecast scenario. It is simply too early, with too much uncertainty to favor one longer-range forecast over another. For now, stay tuned. For those across Micronesia, the showery pattern will remain in place near 91W. Rainfall could be locally heavy at times with stronger wind gusts. If, and when, development occurs, impacts could expand across more islands and atolls of the FSM.

DROUGHT OUTLOOK:

Based on the April 23, 2026 US Drought Monitor weekly assessment, rainfall remains sufficient across much of the region to meet local water needs. However, a dry April is resulting in some water shortages and concerns across southwestern areas, specifically the Republic of Palau and Yap State.

A Public Advisory from Palau’s National Emergency Management Office on April 27, 2026: Palau’s National Emergency Committee declared a “Water Shortage WATCH” for the Republic of Palau, stating that water levels at Ngerimel and Ngerikiil reservoirs in Airai, as well as other water sources around Palau, have dropped due to insufficient rainfall and heightened water consumption. Additionally, the states of Ngarchelong and Ngaraard are already in critical water levels, in which water rationing is being implemented. Hatohobei State is also experiencing severe water levels at this time.

Across Yap State, browning vegetation has been reported across several islands/atolls, including Yap Proper, with water shortages at Ifalik and Eauripik. The current, unsettled weather pattern across the region south of 10N could bring much-needed rainfall to many islands and atolls, but of course, rainfall over any given location, is not guaranteed.

Looking ahead, near-, to below-normal rainfall is anticipated for southwestern islands and atolls, particularly across Palau and Yap State, through the next several weeks. Impact reports and feedback are much appreciated from islands and atolls across the region.

Tropical Formation May Pose a Threat to Portions of the Region Next Week; Uncertainty Remains

The National Weather Service (NWS) Guam Weather Forecast Office is monitoring the potential for a tropical circulation to form in the next few days somewhere in eastern Micronesia. NWS Guam notes that latest model data suggests this potential circulation could pass near or south of the Marianas in the May 3-6 timeframe.

High uncertainty remains regarding the development of this potential system, its track, and timing, which are all subject to change. NWS forecasters continue to monitor satellite data across the region for the eventual emergence of a circulation later this week. This forecast will be closely monitored and may be updated as it becomes clearer how the circulation will develop in eastern Micronesia.

At this early time, the community is advised to stay up to date with the latest information.

Tuesday, April 21, 2026 Valid 1:00 PM

We have received many reports of haze the last few days and several of us have seen it as well. Satellite this morning showed milky sky conditions near the Marianas, likely seeing some of the haze that is being observed. We tracked this haze all the way back to Asia as far west as India where several wild fires are occurring. Smoke only seems to be a part of the hazy conditions with several other particulates mixed in. These particulates were carried eastward from the large wind field of Sinlaku last week. The last few days have seen stable atmospheric conditions, which allows for air to sink and for these particulates to get trapped near the surface. It is possible that those who with sensitive respiratory conditions could be feeling impacts due to the haze. The hazy conditions look to decrease over the next couple of days as easterly trade-winds increase.
