Notice, accept, decide
Like a good sailor, though I am not one, checking weather from multiple reliable sources and methods.
I like Mr. Weatherman Asia overall, and Zoom Earth for accurate visuals, and they say always check Guam weather services (link below). Should be a lot more dead reckoning (up/down all around) onisland in about a week.
No, there is currently no active “invest” or suspect area tracking toward Saipan or the Marianas. [1]
As of August 3, 2026, the National Weather Service (NWS) Guam and the Joint Typhoon Warning Center (JTWC) state that there are no suspect areas for tropical development within the local region. [1]
An active system, Invest 93W, is located far to the west of Palau and poses no threat to the Marianas. Additionally, Typhoon Dolphin (12W) has tracking models moving it well to the north over open ocean toward Japan, meaning it is leaving the local area of responsibility. [1, 2]
Current Regional Outlook for August 12
While there is no looming storm system or tropical depression to fret over right now, you should keep the following in mind for your travel date:
- The Monsoon Surge: The region is currently experiencing a heavy westerly monsoon surge. This is why the August 12 forecast predicts scattered thunderstorms and breezy conditions rather than a tropical cyclone.
- Rapid Shifts: Because August is the heart of the tropical wet season, conditions in the Western Pacific can change in a matter of days. [1, 2]
You can keep an eye on real-time developments by monitoring the NWS Guam Tropical Weather Dashboard as your trip approaches.
