Tropical Storm Krosa Update #12

Issued (2230 UTC) 630am PhT 110313

Tropical Storm Krosa continues to weaken as it moves across the South China Sea. The storm center was last located approximately 430km southwest of Hong Kong. Maximum sustained winds are now down to 75kph with gusts of up to 95kph. TS Krosa is moving southwestward at 10kph.

Latest satellite image shows convection is nearly gone now and the low-level center is becoming fully exposed. Upper-level winds continue to take their toll on the system leaving the core disjointed between the low-level and mid-level circulations. Krosa will continue to weaken as conditions in the region remain unfavorable for cyclone development.

Tropical Storm Krosa will continue moving southwestward and could dissipate by as early as tomorrow. It will move near Hainan later today but we are not expecting any significant impacts anymore aside from strong winds and rough waves along the coast.

The satellite image also shows rainclouds associated with Tropical Depression 30W affecting parts of Visayas and Mindanao in the Philippines. This developing depression was last located approximately 160km east of Surigao City and is currently moving west northwestward at 20kph. For some reason, PAGASA hasn't upgraded this to a Tropical Depression yet; both JTWC and JMA have already done so.

This depression will continue moving towards Visayas bringing unsettled weather in the region. Some places, especially in Northern Mindanao, Cebu, Bohol, Siargao, and Leyte may see 50mm or more of rainfall through the next 12 hours. Strong winds and rough waves will also threaten the said areas.

We'll have more updates later today.
