Tropical Storm Jebi (Jolina) Update #1

Issued (0130 UTC) 930am PhT 073113

A new Tropical Cyclone has formed in the West Philippine Sea (South China Sea). Tropical Storm Jebi or Bagyong Jolina was last located approximately 520km west northwest of Manila or about 800km south southeast of Hong Kong. Maximum sustained winds are estimated to be around 65kph with gusts of up to 85kph. TS Jebi is moving west northwestward at 10kph.

Latest satellite image shows a consolidating cyclone with strong convective activity and improved banding
wrapping around a low-level center. TS Jebi showed improvements last night prompting several agencies to upgrade it to a Tropical Storm. Even though the system is now moving away from Luzon, rain showers caused by the storm will still affect parts of the island especially the western portions.

Tropical Storm Jebi is located in an area of light to moderate wind shear and high sea surface temperatures. Therefore, TS Jebi is forecast to continue slowly intensifying today as it moves across the West Philippine Sea. Latest computer models show a northwestward track that could take the storm towards the island of Hainan by Friday.

We'll have another update later this afternoon.
