There hasn't been much improvement today with regards to TS Jebi's organization. Strong, yet fragmented, convection continues to form near the low-level center.Wind shear is still light to moderate and upper-air environment seems to conducive enough to allow Jebi to continue slowly intensifying.
Forecast Track (NOT OFFICIAL!)
Tropical Storm Jebi is forecast to continue moving northwestward across the West Philippine Sea (South China Sea) over the next few days. Although it is moving away, rain showers are still affecting parts of Western Luzon. We expect Jebi to start affecting Hainan beginning Friday and will last into Saturday. Eventually, Jebi is forecast to move westward possibly affecting parts of Guangdong and Northern Vietnam.
We'll have another update later this afternoon.
