Typhoon BOPHA has been slow in intensification and movement, and is now caught up by Typhoon SAOMAI. Hence this typhoon will be under the influence of Typhoon SAOMAI and be swung around it. Sakishima Islands are now in the area of strong winds, but will be off the area because the typhoon is forecast to move south.

Typhoon BOPHA is affected by Typhoon SAOMAI and its track is being pushed down toward south. According to the forecast this morning, the tracks of three typhoons were relatively in parallel, but it seems that influence of Typhoon SAOMAI is getting stronger.

Typhoon BOPHA is likely to move from south of Sakishima Island toward Taiwan or Philippines. Three typhoons still remained to be small, so, according to forecasts, it is more likely that they will move in almost parallel with a little repulsion than they will show complex tracks due to interference among multiple typhoons.

Typhoon BOPHA was formed in south of Japan. The forecast says that it will move in south of Okinawa, but the forecast circles are big, which means that its track is difficult to forecast. One reason is that you cannot neglect the effect of other typhoons. Due to the formation of Typhoon BOPHA, three typhoons are now crowded in a relatively small region of the Pacific. It is well known that the forecast of typhoons becomes difficult when multiple typhoons are located proximately due to interaction among typhoons. For example, if you study a case that three typhoons, Typhoon 198512, Typhoon 198513 and Typhoon 198514, are located in the Pacific, you can see complex typhoon tracks due to interaction among three typhoons. In particular, the largest typhoon, Typhoon 198513, looks as if it is "pushing around" a smaller typhoon, Typhoon 198512. Until now, a typhoon showing the most steady intensification is Typhoon MARIA, but it is still relatively small, so it may not give so much influence to others. Depending on which typhoon's movement is a key, the forecast may change significantly from day to day, so it is necessary to check the latest typhoon information frequently.
