Track and Intensity Outlook

Betty is expected to continue on its west-northwest or northwest trajectory until tomorrow, gradually decelerating. By Tuesday, the typhoon will likely become slow-moving to almost stationary over the waters east of Batanes. It is then projected to move northward or north-northeastward by mid-Wednesday or Thursday towards the sea east of Taiwan.

Throughout the forecast period, Betty is expected to remain as a typhoon, although it is predicted to weaken gradually until Tuesday. A faster weakening rate may be observed as it moves northward or north-northeastward on Wednesday or Thursday due to increasingly unfavorable conditions. Betty may be downgraded to severe tropical storm category on late Thursday or early Friday.
