Residents across Guam and the CNMI are being advised to prepare for heavy rain and thunderstorms as Invest 92W approaches the region.
The National Weather Service (NWS) in Guam reported Thursday that the developing system was located about 250 nautical miles east-southeast of Guam as of 8 a.m., moving west-northwest at around 10 mph.
Forecasters say Invest 92W has shown signs of renewed organization after a brief lull, with showers and thunderstorms beginning to redevelop around its center. While environmental conditions remain favorable for development, the system is still weak and disorganized, and any strengthening is expected to occur gradually over the next 24 to 48 hours.
The disturbance is expected to pass through the Marianas between Thursday evening and Friday morning, likely as a “tropical disturbance or possibly a tropical depression”. No tropical storm or typhoon watches or warnings are currently in effect.
Residents can expect “periods of heavy rain, thunderstorms and gusty winds” as the system moves across the islands.
According to NWS Guam, the strongest winds associated with the system are expected north of its center, meaning “Tinian and Saipan could experience stronger gusts”, while Guam may see comparatively lighter winds.
Despite its relatively weak structure, the system poses a risk of “localized flooding”, especially in low-lying and poor drainage areas where heavy rain bands may persist.
Elsewhere in Micronesia, separate weather disturbances embedded in the near-equatorial trough are bringing heavy showers to Chuuk, Pohnpei, Kosrae and Majuro, where special weather statements are in effect warning of potential flooding and mudslides.
Emergency officials are urging residents to stay informed and prepared as conditions evolve.
The NWS advises residents to monitor forecasts and updates, noting that while no warnings are currently in place, changes are possible if the system strengthens more quickly than anticipated.
