Khanun setting its sights for Hainan

Good evening from the Western Pacific Weather team.

Tropical Storm Khanun (Odette) is making its way out of the Philippines, though the system continues to influence the weather pattern for the country. While the rainfall has significantly decreased for Luzon, a return flow is bringing rain into Cebu and the surrounding islands. The winds will continue to be in place for the overnight period but will decrease toward Saturday.

Once the system completely exits the Philippines, those in Hainan and the southern coast of China will need to be prepared for Khanun’s approach by the end of the weekend. The system will continue to move north and west on Sunday and potentially intensify into a strong typhoon Sunday, though the latest thinking is that the system will encounter some resistance and struggle to maintain its strength into the first part of next week. Hainan should see deteriorating conditions come Monday.

Those in northern Vietnam will have to be on the lookout for this system as a previous storm brought significant amount of rain, leading to at least 37 deaths with thousands of homes evacuated due to the flooding and mudslides. Khanun, even in a weakened state, could still threaten to cause more flooding and problems next week.

Tropical Storm crossing northern Luzon

Good morning from the Western Pacific Weather team.

On this Friday, we have a tropical storm on our hands in northern Luzon as the system is crossing over the region. Tropical Storm Khanun (Odette) is bringing strong gusts of up to 100 kph along with rainfall rates exceeding 15 millimeters per hour. A Signal 2 warning is in effect for the far northern islands with possible gusts expected to hit up to 120 kilometers per hour along with persistent, battering rains.

We’re expecting this system to continue bringing stormy conditions throughout Friday and into a part of Saturday before it moves out into the open waters. Those north of Baguio City will have to brace through the storm for the next 48 hours.

Once Khanun heads out into sea, its next focus will be on the island of Hainan and the southern China coastline. The system is expected to intensify into a strong typhoon by late Sunday into Monday, bringing a significant threat to the coast with a high storm surge, powerful winds, and flooding rainfall. Northern Vietnam, which has just endured through a tropical depression earlier in the week, will once again contend with a tropical system, and it is likely that the storm will be more powerful this time around.
