Satellite imagery shows a mix of sun and clouds with a few passing showers over the American Samoa islands this morning and early afternoon. With a low pressure system located to the south of Fiji, this has generated northeasterly winds over the territory with gusts reaching up to 20 mph. The northeasterly winds are anticipated to increase the likelihood of rainfall to numerous showers (60% chance) from tonight through Monday night. Flash flooding is not anticipated from these showers. As the aforementioned low continues to move away, winds become easterly by Tuesday over the territory and is expected to decrease through Wednesday night. If showers develop along the easterly flow, it would be in the passing form. Otherwise, we expect a mix of sun and clouds throughout Tuesday and Wednesday. .Long term... For late this week and into the upcoming weekend, easterly flow continues to decrease to light and variable winds making for a warmer than average and humid timeframe.
