NWS Guam is monitoring a tropical disturbance near Pohnpei, Invest 90W | News

On By Karl

A weak tropical disturbance called Invest 90W has been slowly moving westward across Pohnpei State for the past few days, causing showers, locally heavy rainfall and strong winds, Guam National Weather Service said in a statement.

A tropical disturbance could make its way to near Guam this weekend, but no significant weather impacts are expected at this time.

For now, residents can expect an increased chance of clouds, showers and light thunderstorms throughout the weekend, the NWS said.

An ill-defined circulation was centered near 4.0N 155.0E near Pohnpei. As of Thursday afternoon, 90W remains a very poorly organized disturbance characterized by a broad area of ​​showers, thunderstorms, and strong gusty winds stretching across Chuuk, Pohnpei, and Kosrae Provinces, the NWS said.

High winds and periods of heavy showers will create hazardous sea conditions for inter-island travel.

The Joint Typhoon Warning Center said Thursday afternoon: “90W is in an environment marginally favorable for development with warm sea surface temperatures, low to moderate vertical wind shear, and weak upper-level equatorward flow.

The NWS said global models are in good agreement that Invest 90W will track generally toward the northwest over the next 48 hours.

The NWS said 90W is rated “moderate” in development, meaning it has a high chance of developing into a tropical depression but is expected to occur after 24 hours.

Numerical prediction models vary, as do poorly organized disturbances at this early stage. Most forecast scenarios will bring 90W some way near or south of Guam this weekend, the NWS said.

At this stage, it is too early to tell how 90W will develop during its journey through Micronesia and its passage near Guam.

“Weather conditions and forecasts will change as this situation evolves. Significant weather impacts are not expected at this time, but we will monitor 90W closely,” the NWS said.
