448 FXZS60 NSTU 202138 AFDPPG Area Forecast Discussion National Weather Service Pago Pago AS Issued by National Weather Service Honolulu HI 1138 AM HST Thu Feb 20 2020 .Discussion... Current satellite images show that the center of Tropical Depression 09F is very close to Tutuila, is moving generally eastward, and will likely bring impactful weather to the island through the afternoon. Heavy showers and thunderstorms wrapping into the low are pounding the area, and wind gusts over 70 mph have been recently observed, with widespread power outages reported. 09F is expected to move away from the region tonight, leading to a break in the wind and rain, but this appears to be short-lived. Another tropical low has formed within the active monsoon trough over the region, and is currently centered near 12S 177W, or about 450 miles west-northwest of Tutuila. Latest model guidance, (which has not performed exceptionally well with the details of the recent weather) indicates that this low will pass over the region late Friday into Saturday, potentially bringing another round of high wind, flooding rain and high surf. This low is expected to depart the area by Saturday night, leaving the islands in a generally wet northerly flow that will likely persist into the middle of next week. && .Marine... Gale force winds associated with Tropical Depression 09F are buffeting the region, with a gust to 65 kt recently reported at Pago Pago airport. Seas have responded, and are 12 to 14 feet at the Aunuu buoy, and are likely higher near the core of the low, currently estimated to be very close to Tutuila. As the depression moves away tonight, winds and seas may diminish somewhat, but this is expected to be short-lived as yet another tropical low is expected to cross the region - potentially as early as Friday night/Saturday. Gale force winds are expected with this system as well. After this low moves away, a wet northerly flow is expected to prevail, and seas should generally trend down. && .PPG WATCHES/WARNINGS/ADVISORIES...
