1010 AM ChST Thu Apr 24 2025



Tropical Weather Discussion for the Western North Pacific between

the Equator and 25N from 130E to 180. The following information is

based on recent satellite imagery/data, weather observations, radar,

and meteorological analysis.



...SPECIAL FEATURES...



None.



...OTHER WEATHER SYSTEMS...



NEAR EQUATORIAL TROUGH...

A near-equatorial trough meanders through the Philippines to enter

Micronesia at 5N130E to end near EQ145E. This trough has westerlies

to the south of it, but the westerlies do not extend all the way back

to the Indian subcontinent so it is not at this time a monsoon

trough. Scattered showers and isolated thunderstorms are found in

southern portions of the Republic of Palau, including Tobi and

Helen's Reef (Hatohobei) but south of Angaur, and south of Yap State.

This feature is expected to intensify slowly while showing little

change of position over the next several days, and early next month

could morph into a true monsoon trough if it can connect to the

westerly winds coming off of India, as those start to get going in

May.



TRADE-WIND TROUGHS...

A trade-wind trough in the CNMI is creating scattered showers from

Anatahan northward. This trough is expected to shift westward while

gradually weakening, as it is part of the remains of a frontal

system.



Another trade-wind trough near Chuuk is generating scattered showers

in eastern Chuuk and western Pohnpei States. This feature is forecast

to shift westward with little change of intensity over the next few

days.



A third trade-wind trough near Kosrae is producing scattered showers

and isolated thunderstorms near and south of Kosrae. This feature is

also expected to shift westward with little change of intensity over

the next few days.
