Typhoon Krosa Update #9

Issued (13 UTC) 9pm PhT 110213

Typhoon Krosa has slowed down as it moves across the South China Sea. The eye of Typhoon Krosa was last located approximately 250km south southeast of Hong Kong. Maximum sustained winds are at 165kph with gusts of up to 205kph. Typhoon Krosa is moving west northwestward at 15kph.

Hong Kong Observatory has issued a Standby Signal No.1 due to the proximity of Typhoon Krosa. While no immediate action is necessary, the agency is issuing precautionary announcements regarding high waves generated by the storm.

Latest satellite image shows Krosa lingering south of China. The system has slowed down significantly over the past 24 hours as the steering environment in the region has weakened. The warm sea temperatures and weak wind shear has also allowed Krosa to intensify into a Category 2 Typhoon. We have noticed, however, that the eye is becoming more ragged which may hint at some weakening.

Typhoon Krosa will move slowly westward tonight. Outer rain bands may affect the coast of Guangdong Province including Hong Kong and Macau tonight and into tomorrow. Gusty winds of up to 80kph are also possible, especially in more exposed areas.

Typhoon Krosa will then turn to the southwest as a ridge of high pressure begins to build near the system. Wind shear is also forecast to increase which will lead to gradual weakening of Typhoon Krosa in the coming days. The system may move near the island of Hainan beginning tomorrow (Sunday) and into Monday. Strong winds and rains are possible there.

We'll have another update tomorrow morning.
