Haikui struggling on its way toward the Indochina Peninsula

Good evening from the Western Pacific Weather team.

Those in Vietnam, especially in the central areas of the country, will have to keep watch over the next 24 hours, but there is some possibly good news in regards to Haikui. The tropical storm is having some issues for a couple of reasons. First, the sheer against the storm (the winds higher up in the atmosphere) are blowing against the system, creating some problems for the storm. In addition, the sea surface temperatures have cooled off to the point where Haikui may be unable to sustain itself much longer. However, given the fact that central Vietnam has seen a tremendous amount of rainfall during the past two weeks, any additional rainfall will be of issue. While JTWC expects the storm to dissipate south of Hainan late Sunday (and more in line with the current thinking at WestPacWx for now), JMA continues to place Haikui on a course to make landfall in central Vietnam sometime Tuesday. It is best to be aware of both scenarios, but it should be important to know that the storm is having some issues at the current moment as it attempts to move westward.
