Tropical Storm Jebi Update #5

Issued (0130 UTC) 930am PhT 080213

Tropical Storm Jebi continues to intensify as it nears the island of Hainan. Jebi was last located approximately 320km south southeast of the city of Haikou. Maximum sustained winds are up to 85kph with gusts of up to 110kph. TS Jebi is moving north northwestward at 10kph.

China Meteorological Administration has issued a Yellow Warning for parts of Guangdong due to the impending approach of Tropical Storm Jebi. Strong winds and heavy rains are forecast which could prove dangerous especially in disaster prone areas. Keep checking the news and bulletins from your local officials to stay ahead of this storm!

Latest satellite image shows an improving organization with a comma-head shape appearing. Much of the strong convection is still located southwest of the center; however, the low-level center itself seems like its under the cloud canopy now. Satellite analysis suggests a very wide wind field that stretches as far north as Hong Kong. In fact, the airport in Haikou is now starting to report winds of 40 to 50kph and will only get stronger as the storm nears landfall.

Radar Image from CMA

Latest radar out of Hainan shows squally rain showers associated with Jebi's circulation. The main batch of heavy rain is not forecast to move until later this afternoon. Expect deteriorating conditions today with heavy rains and strong winds occurring later tonight when Jebi is forecast to make that landfall. As much as 250mm of rain is possible along with damaging winds! For the latest radar image, please click HERE (CMA Website).

Tropical Storm Jebi will then move into the Gulf of Tonkin by Saturday and could make another landfall, this time in Vietnam by late Saturday evening or early Sunday morning. Stormy conditions should be expect across Southern Guangdong and Northern Vietnam (including Hanoi).

We'll have another update later today.
