Tropical Storm Cimaron (Isang) Update #5

Issued (2330 UTC) 730am PhT 071813

Tropical Storm Cimaron (Bagyong Isang) continues to move away from Luzon on its way towards Southern China. The storm was last located approximately 180km southeast of Shantou in the province of Guangdong or about 450km northwest of Basco, Batanes. Maximum sustained winds are at 75kph with gusts of up to 95kph. TS Cimaron is moving northwestward at 25kph.

As of 5am this morning, PAGASA has dropped all Public Storm Warning Signals in the Philippines.

Latest satellite image shows the convection associated with Cimaron is being sheared slightly to the northeast leaving the low-level center somewhat exposed. Nevertheless, satellite analysis suggest that winds have actually increased a little bit overnight. But as we've said before, Cimaron shouldn't intensify that much especially now that it is nearing landfall.

Radar from CWB Taiwan

Latest radar out of Taiwan shows bands of light to moderate rain impacting the southern half of the island. As much as 50mm have already been recorded so far and another 50 to even 100mm of rain could still fall. Oversaturated ground in the region could lead to landslides and flashfloods, residents in Southern Taiwan are advised to take precautionary measures especially those near prone areas.

Tropical Storm Cimaron is forecast to make landfall in Guangdong Province, just north of Shantou, later today. Widespread rains are forecast for the province tonight and tomorrow. After making landfall, Cimaron is expected to quickly lose strength and should totally dissipate by tomorrow evening (Friday).

We'll have another update later this afternoon.
