SYNOPTIC DISCUSSION

MONDAY 22ndAPRIL 2024 – PM SHIFT

TONIGHT INTO TOMORROW:

A convergence zone was analyzed to the southwest of the group, such a system has introduced scattered showers with moderate falls. The most recent satellite images reveal the presence of open cell cumulus clouds traversing the region, resulting in steady rainfall throughout the day, which can be intense at times. This weather pattern is expected to persist over the week as a high-pressure system located to the south shifts eastward. A mild to moderate easterly breeze will continue to sweep across the islands for the duration of the week. The atmospheric profile from this afternoon indicates instability. The likelihood of thunderstorms is on the rise, accompanied by an uptick in shower activity in the region. Consequently, anticipate intermittent showers and mild to moderate easterly winds tonight and throughout the short-term forecast period.

 

TUESDAY THROUGH SUNDAY:

Samoa is in a bit of weather variability over the coming days. Tomorrow, there's a convergence that might bring some scattered showers, accompanied by moderate easterly winds. Then, a ridge of high pressure will move in from the southeast, shifting winds to light northwest breezes by Wednesday. These northwest winds will gradually veer northeast as the ridge moves southward, sticking around through Friday. By Saturday, Easterlies will prevail over the islands through the weekend with minimal showers.

 

MARINE OUTLOOK:
At present, the activity of waves and swells is quite low, remaining under the advisory limit for the foreseeable future. Forecasts indicate that these conditions are likely to persist throughout the remainder of the forecast period. However, a new wave and swell surge is anticipated to reach the nation's shoreline by next Saturday. It's advisable to stay updated, particularly if your activities are influenced by wave and swell conditions.

ADVISORY/WARNING:

NONE!
