TEMBIN (IGME) is expected to move slowly SW to Southward during the next 12 to 48 hours...and will make a counter-clockwise loop and move ENE to NE-ward through 72 hours. On the forecast track, the core of TEMBIN will slow down while over the West Philippine Sea...and will move East to ENE back towards the Southern tip of Taiwan on Monday. The u-turn track of TEMBIN is mainly due to the direct interaction with Typhoon BOLAVEN which is dictating Tembin's motion.

Maximum Sustained Winds (1-min. avg) have decreased to near 110 km/hr (60 knots) with higher gusts. Some increase in strength will be expected during the next 2 to 3 days...and TEMBIN will regain Typhoon status on Saturday.

Tropical Storm Force Winds (62-117 km/hr) extend outward up to 270 kilometers (145 nautical miles) from the center. TEMBIN is an average-sized tropical cyclone with a diameter of 555 kilometers (300 nautical miles) across.

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

SATURDAY EVENING: Moving slowly into the West Philippine Sea...regain Typhoon status...about 276 km SW of Kaohsiung City, Taiwan [6PM AUG 25: 21.5N 117.9E @ 130kph].
SUNDAY EVENING: Completed its counter-clockwise loop...starts to move ENE back towards Southern Taiwan...about 250 km SW of Kaohsiung City, Taiwan [6PM AUG 26: 20.9N 118.7E @ 150kph].
MONDAY EVENING: Starts interacting with the larger Typhoon Bolaven...accelerating NE-ward...approaches the Southern tip of Taiwan...about 94 km SSE of Kaohsiung City, Taiwan [6PM AUG 27: 21.8N 120.6E @ 140kph].

*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.


Below is the summary of the storm's parts and its hazards affecting specific areas. You can also view this image link for you to understand the parts.

CENTRAL DENSE OVERCAST (CDO) - over water (West Philippine Sea)...possible "Eye" reforming underneath the cirrus canopy. Near-Typhoon Conditions w/ Near-Typhoon Force Winds (95-140 kph) will be expected along the CDO (click here to know more about CDO).
INNER RAINBANDS - affecting and spreading across Western & Southern Taiwan. Tropical Storm Conditions with Tropical Storm Force Winds (62-94 kph) will be expected along these bands.
OUTER RAINBANDS - affecting & spreading across the rest of Taiwan, the tiny island group of Batanes, Calayan, Babuyan, Ishigaki and Yaeyama Islands. Cloudy/Rainy Conditions with moderate to strong winds (<62 kph) will be expected along these bands (click here to know more about Rainbands).
24HR TOTAL RAINFALL ACCUMULATION - from 5 up to 200 mm (low to high rainfall) can be expected along areas affected by the outer & inner rainbands (see above)...with isolated amounts of 201 to 510 mm (high to very high) along areas near the center of Tembin (Igme) (click to open NOAA's eTRaP graphic).
COASTAL STORM SURGE FLOODING - possible 1-3 ft [0.3-0.9 m] above normal tide levels...accompanied by large and dangerous battering waves can be expected along the coastal, inland lakes and beach front areas of Southern & Western Taiwan. Very minimal damage is likely on this type of storm surge. Danger from Rip Currents or Rip Tides can be expected along the rest of the beach-front areas of Northern Luzon, Southern China and the rest of Taiwan
