Tropical Depression 09F originally formed northwest of Savaii in an expansive area of deep convection and tropical instability, which was reflected well in the rapidly cooling cloud top temperatures noted on IR satellite. TD 09F moved through American Samoa���s area of responsibility (AOR) Thursday morning (Feb 20th) before Fiji Met Services named the system Tropical Storm Vicky (1205pm Thurs afternoon). A Tropical Storm Watch issued Thursday,  was for another developing tropical system northwest of Savaii, 98P, which eventually became known as Tropical Storm Wasi.
The system generated a period of strong winds across American Samoa Thursday morning, between 30 to 50 mph with gusts in the 60s.  At NWS Pago Pago, highest wind observations Thursday morning (around 8am and 9am) were sustained at 46 mph with gusts to 75 mph.
American Samoa Power Authority (ASPA) reported���.25 customers sustained damage to their house and meters,  Power outages reported in villages Tutuila, Manua and Aunuu. Over 300 people were in emergency shelters. 50 people from Onenoa were housed in an emergency shelter, result of their home being washed over by waves. Hawaiian Air announced that they would not operate additional flights through the weekend. Samoa Airways and Talofa Air both suspended flights to American Samoa in the wake of Tropical Storm Vicky and in advance of Tropical Storm Wasi. Pago Pago International Airport extended its closure.
The extensive amounts of damage experienced on American Samoa���s Islands the weekend prior, by the strong winds Saturday night (Feb 15) through Monday (Feb 17), is what likely lessened storm damage experienced with Tropical Storm Vicky Thursday (Feb 20), and eventually during the weekend with Tropical Storm Wasi.
