As the tropical Storm Tembin regained its strength and became a typhoon again, Taiwan Central Weather Bureau announced the sea warning at 11:30 AM on Aug 26 again. The weather bureau would probably issue the land warning again. Tembin is most likely to make landfall in Pintung County and then go north along the east coast which would effect the entire island. The south crossing island railroad has been shut down since its first landfall and still is under repair. Also many areas are still without a power supply, phone and internet services. So be precaution when traveling to Pintung County and Taitung County.

cyclones. In general, two tropical cyclones may start to affect each other when
the distance between them is around 12 latitude degrees (about 1350
kilometers). When this occurs, The tropical cyclones will rotate around one
another in a counter-clockwise direction (in Northern Hemisphere) about their
geometric centre. The centre needs not be the middle of the axis. The stronger
cyclone tends to have a dominant effect on the track of the weaker one. The
interaction will end when: there is a stronger influence of a large scale weather
system from outside, one of the tropical cyclones weakens or the two
cyclones merge. Research by the Observatory shows that if the distance
between the two tropical cyclones is 1200 kilometers or more, the chance of
merging is slim.
