Latest satellite image shows strong convection that is now becoming more expansive, spreading northeastward and over the low-level center. Overall organization has also improved with formative banding wrapping around the circulation center. Further intensification is expected especially as we move into diurnal maximum.
Tropical Storm Jebi will continue moving northwestward and should start bringing rains into Hainan beginning tomorrow (Friday). It is forecast to make landfall tomorrow evening and will pass south of the city of Haikou. Jebi will, then, emerge into the Gulf of Tonkin and could make a second landfall in Northern Vietnam by Saturday.
We'll have another update tomorrow morning.
