The system will be gradually steered by the subtropical ridge anchored SE of Japan and will turn into a WNW direction.

Intensity Analysis 強度分析
14W had a T-number of 1.5 at 06 UTC that translates to maximum wind speed of 25 knots (tropical depression). Recent analyses showed that there is a possibility that 14W will never develop any further due to the interaction between 14W and a broad cyclonic circulation (95W) west of it. From satellite imagery, it seems that 14W has become part of the circulation of 95W and the competition of water vapour has been prohibiting 14W from strengthening. This bulletin favours the outcome that 14W will eventually be dominated by 95W and thus a weakening of the system is expected in 24 hours.
Due to the southern extension of the broad subtropical ridge, 14W is currenly moving northwards with a small western component. It is expected that when 14W continues to move northward, it will be gradually steered by the subtropical ridge anchored SE of Japan and thus will turn into a more westerly direction.
14W had a T-number of 1.5 at 08 UTC that translates to maximum wind speed of 25 knots (tropical depression). It is expected that 14W will gradually intensify as it encounters warm sea surface temperatures and low vertical wind shear.
