Khanun intensifies, departs from the Philippines

Good morning from the Western Pacific Weather team.

The Japan Meteorological Agency has upgraded Khanun’s status to a severe tropical storm during its 00 UTC update for Saturday. The system has been responsible for battering the northern areas of Luzon over the past couple of days. Khanun is now slowly exiting the region, though some of the residual moisture flow and instability will lead to some windy conditions and occasional rain for the day.

As Khanun embraces the waters of the South China Sea, it is expected to intensify into a strong typhoon. While there are some decently warm waters over the sea, the temperatures are not high enough to generate a significant intensification over the next couple of days. That being said, Khanun will still likely maintain its status as a strong typhoon as it approaches the island of Hainan late Sunday into Monday morning. Residents from Hong Kong westward will see increasing surf and deteriorating conditions late Saturday and throughout the day Sunday. The worst time period will be late Sunday and throughout the day Monday when the storm is expected to make landfall over Hainan.

The interaction of the land with the system will likely weakened the storm, but given the current circumstances with the mudslides and flooding of this past week, those living in northern Vietnam will be contending with dangerous conditions as intense rainfall along with some moderately strong winds makes its way into the region Monday and Tuesday. Residents will need to prepare for evacuations to safer and higher grounds, especially for those who have already been impacted by this past week’s weather.
