RapidScat data showed that the strongest sustained winds stretched from northwest to northeast of the center at speeds up to 30 meters per second (108 kph/67 mph). Strong winds wrapped around the center of circulation from northwest to east to the southern quadrant, while the weakest winds were on the storm's western side.

Halola was located near 24.0 North latitude and 137.1 East longitude, about 554 nautical miles (638 miles/1,027 km) east-southeast of Kadena Air Force Base, Okinawa, Japan. Halola was moving to the north at 9 knots (10.3 mph/16.6 kph).
