Latest satellite image shows strong convective activity forming near the circulation center. The low-level center is partially obscured but is still displaced somewhat from the main cluster of clouds. Nevertheless, TS 09W is in an area of favorable conditions and should continue developing over the next few days.
Forecast Track (NOT OFFICIAL!)
Our preliminary forecast is based mainly on the GFS model and the current atmospheric conditions in the region. Tropical Storm 09W will affect Guam and the Mariana Islands tonight and into tomorrow. Rainfall amounts of up to 100mm are possible. The system will then head westward, intensifying along the way. We expect 09W to become a Typhoon by early next week and could threaten parts of the Philippines later that week.
We'll have another update tomorrow morning.
