Discussion

Thunderstorms from the previous forecast brought heavy rainfall this Christmas morning. Flooding reports were received from the villages of Leone and Vailoa. However, WSO Pago Pago observed less than an inch of rain within the past 12 hours, which only prompted a flood advisory. Although we are currently experiencing a break in showers, model data suggests numerous to widespread showers to persist through the weekend as the trough becomes more active. As of now, the risk for flash flooding is low, especially as thunderstorms have diminished. However, the atmosphere appears to be moist and unstable on the recent balloon data. Meanwhile, a high pressure system centered southeast may allow for an east breeze of 10 to 15 mph through Sunday.

A low pressure is expected to develop east of Manu'a Sunday night. This feature will draw moisture from the trough east and diminish rainfall for the territory. Light winds and isolated to scattered showers will persist through the end of the new week.
