3-DAY FORECAST OUTLOOK & ANALYSIS*
JELAWAT (LAWIN) is expected to continue moving slowly NW to NNW-ward with little change in its forward speed during the next 24 hours...recurving NE-ward through 72 hours. On the forecast track, the core of JELAWAT will just remain over the North Philippine Sea, passing near to the east of the Batanes Group later today...passing just south of Ishigaki Jima on Friday afternoon. This system will be passing very near Okinawa Islands on Saturday afternoon or evening.
Maximum Sustained Winds (1-min. avg) have decreased to 240 km/hr (130 knots) with higher gusts. Continued weakening is expected during the next 3 days as Jelawat moves into lower Ocean Heat Content (OHC) or cooler sea-surface temperatures.
Typhoon Force Winds (118 km/hr or more) extend outward up to 100 kilometers (55 nautical miles) from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 305 kilometers (165 nautical miles). JELAWAT is a very large-sized tropical cyclone with a diameter of 1,090 kilometers (590 nautical miles) across.
The following is the summary of the 3-day forecast outlook on this system:
FRIDAY MORNING: Just below Super Typhoon strength...starts to recurve after passing well to the ENE of Batanes Islands...about 246 km S of Ishigaki Jima [6AM SEP 28: 22.3N 123.9E @ 230kph].
SATURDAY MORNING: Exits the Philippine Area of Responsibility (PAR)...rapidly accelerates toward Okinawa Islands...weakens to Category 3...about 210 km SW of Kadena Airbase [6AM SEP 29: 25.0N 126.4E @ 195kph].
SUNDAY MORNING: Weakens to a Category 2 Typhoon as it rapidly accelerates toward the NE while passing across the Ryukyus...about 179 km ENE of Amami Island [6AM SEP 30: 28.6N 131.2E @ 165kph].
*Please be reminded that the Forecast Outlook changes every 6 hours, and the Day 3 Forecast Track have an average error of 250 km...while the wind speed forecast error, averages 35 kph per day. Therefore, a turn to the left or right of its future track and changes in its wind speed must be anticipated from time to time.
