Severe Tropical Storm Usagi (Odette) Morning Update

Japan Meteorological Agency has upgraded Usagi into a Severe Tropical Storm as the system continues to intensify across the Philippine Sea. STS Usagi (Bagyong Odette) was last located approximately 1,050km east northeast of Manila. Maximum sustained winds have increased to 95kph with gusts of up to 130kph based on JMA’s latest warning.

PAGASA has not issued any signal warnings yet across the Philippines due to the distance of the storm. However, we expect Usagi to start affecting eastern portions of Luzon by tomorrow. Furthermore, Usagi will start to enhance the Southwest Monsoon which could trigger rain showers across parts of the Philippines beginning tomorrow and could last through the weekend.

Latest satellite shot across the Western Pacific shows the improving STS Usagi as well as a low pressure area just east of Vietnam. STS Usagi looks more symmetrical this morning with good convection and poleward outflow. The core has also tightened up and we’re starting to see banding wrapping around the center.

Agencies across the Pacific are expecting Usagi to become a Typhoon as early as tonight and could even become a Category 3 Typhoon as forecast by the Joint Typhoon Warning Center (JTWC). Track consensus among the agencies and the models is putting Usagi between Taiwan and Luzon by Saturday; although JTWC and JMA are showing Usage clipping the southern tip of Taiwan by Saturday. However, do remember that the forecast could still change and so residents from Northern Luzon up to Taiwan should continue to monitor the developments of this storm.

We’ll continue to have update throughout the day. Stay safe!
