Much of the moisture associated with the trough which produced flash flooding conditions earlier has slowly migrated south of the islands with some remnants nearby. This has given way for some sunshine to warm up the rest of the day. On satellite imageries, thunderstorms and deeper convections to the east of Rose Atoll, which are associated with a surface to mid-level low pressure system is also expected to continue to migrate south of the territory. This scenario is shown on the latest model data, with the trough continuing on its southward path as gentle to moderate northeast winds help push and hold the trough to the south of the islands through midweek. Upper air observations (RAOB) from this afternoon (03/00Z) continue to show a moist atmosphere with dry pockets at certain levels. Thus, the flood watch is cancelled. Expect scattered to numerous showers with northeasterlies to remain across the territory for this time frame. By Thursday, winds will turn east as embedded showers in the wind flow moves across the territory. Expect scattered showers with gentle to moderate east winds for Thursday through at least Saturday night. By Sunday, models are showing a trough from the west-northwest moving into the area, likely producing flash flooding conditions. However, will continue to monitor conditions as more data becomes available and as the week progresses. && .Marine... Favorable ocean conditions have been observed for the last 12 to 16 hours as seas remain at 5 to 7 feet with peak periods less than 10 seconds. Observations from the buoys continue to support these conditions for the remainder of the forecast period. Model data is consistent in keeping seas at these levels. However, a south swell with peak periods around 12 seconds and more is expected to reach shores by Monday afternoon and remain for the rest of the week. These long periods are likely to enhance strong rip currents even though seas are in favorable conditions. Winds are also expected to remain at a gentle to moderate northeast flow for tonight through midweek before turning east. Therefore, expect a moderate risk of strong rip currents for this time frame. && .PPG WATCHES/WARNINGS/ADVISORIES... Flood Watch is cancelled && $$ JTAllen
