SAOLA (GENER) is expected to move NNW for the next 24 to 48 hours with little increase in its forward speed...will slightly bend NW-ward between 48 to 72 hours. On the forecast track, the core of SAOLA will remain over the open sea (North Philippine Sea)...passing over Yaeyama Islands on Thursday noon and will move out of the Philippine Area of Responsibility (PAR) late Thursday afternoon. On Friday evening, SAOLA will start to make landfall over Southeastern China very near Wenzhou City.

Maximum Sustained Winds (1-min. avg) are near 120 km/hr (65 knots) with higher gusts. More strengthening is forecast during the next 1 to 2 days, and SAOLA is expected to become a Category 2 Typhoon by Wednesday evening or early Thursday.

Typhoon Force Winds (118 km/hr or more) extend outward up to 35 kilometers (20 nautical miles) from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 185 kilometers (100 nautical miles). SAOLA is a large-sized tropical cyclone with a diameter of 1,480 kilometers (800 nautical miles).

The following is the summary of the 3-day forecast outlook on this system:

WEDNESDAY EVENING: Gaining more strength as it moves slowly NNW away from the Batanes Islands, and approaching Yaeyama Islands...about 206 km SSW of Ishigaki Jima [6PM AUG 01: 22.8N 123.7E @ 150kph].
THURSDAY EVENING: Nears Category 3 strength as it moves out of the PAR...about 173 km East of Taipei, Taiwan [6PM AUG 02: 25.2N 123.3E @ 175kph].
FRIDAY EVENING: Just along the shores of Southeastern China...prepares to make landfall...about 24 km SSE of Wenzhou City, China [6PM AUG 03: 27.8N 120.8E @ 175kph].

*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.
