***************
TD 17W has intensified and is now Tropical Storm Sanba (Bagyong Karen). The system was last located approximately 380km north northwest of Palau or about 930km east of Visayas. Maximum sustained winds are now at 65kph with gusts of up to 85kph. TS Sanba is currently moving north northwestward at 15kph.

Latest satellite image shows convective bands tightening up around the storm's center. Cold cloud tops, especially near the center indicating continuous intensification. Outflow around Sanba's circulation is also pretty good allowing the system to ventilate. Bulk of convection remaining well east of Visayas and Mindanao although some scattered showers could impact Samar, Leyte, and Eastern Mindanao tonight and into tomorrow. Palau, on the other hand, should expect improving weather as Sanba continues to move to the north.
Tropical Storm Sanba is forecast to continue intensifying under favorable conditions in the Philippine Sea. Based on current trends, the system could become a typhoon as early as Thursday or into Friday. As of right now, there is very little chance that the system will make landfall in the Philippines although as said earlier, chances of rains will remain for parts of Eastern Philippines in the next few days. Furthermore, Sanba will likely enhance the Southwest Monsoon (Hanging Habagat) as we head into the weekend.
Forecast Track (NOT OFFICIAL!)
Tropical Storm Sanba will continue tracking generally northward under the influence of a subtropical ridge. By Friday, a trough diving down across Eastern China is forecast to weaken the said ridge and also forecast to pick up Sanba steering it to the north passing near Okinawa by Sunday and eventually moving to the northeast by early next week. Due to the potential uncertainties in the track, residents along Taiwan and the Ryukyu Islands of Japan (especially Okinawa) should continue monitoring the developments of Sanba as it could threaten your plans this weekend.
We'll have another update tomorrow! Don't forget to watch Robert Speta's LIVE UPDATE later tonight!
