Sigh of relief as Haikui dissipates

Good evening from the Western Pacific Weather team.

Those in Vietnam will not have to face the threat of another tropical system for the moment as Haikui has dissipated in the South China Sea. Originally thought to have potential impacts for those in Vietnam, the system struggled to maintain its strength and fell apart during the day Sunday. There is a chance, however, of scattered showers during the afternoon hours on Monday, especially for those in central Vietnam, but otherwise, the weather should remain relatively calm and dry.

The Western Pacific, for the moment, should remain calm when it comes to tropical development during the next 24 hours.

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.

Vietnam in the crosshairs of Haikui

Good evening from the Western Pacific Weather team.

After an active 24 hours in the Philippines due to Haikui, the tropical storm is now heading toward Hainan and Vietnam. The storm is expected to be in the open waters for the next 48 hours and not expected to impact land during that time period. However, Hainan will be contending with strong winds, high surf, and heavy rainfall as the storm brushes by late Sunday and early Monday. The storm may intensify into a Severe Tropical Storm briefly during the weekend before weakening. Be that as it may, the system should pack a bit of a punch this weekend and into the first part of next week.

Vietnam, which has already dealt with a typhoon just the other week, will have to endure through another bout of significant rainfall, leading to concerns of flooding Monday through Tuesday. Be prepared for the winds and rain to pick up during the day Monday and lasting for about 36 hours. Those further inland will be dealing with similar issues during the middle of the week.

Tropical depression to bring significant rainfall into the Philippines over the next 24 hours

Good afternoon from the Western Pacific Weather team.

A tropical low has intensified into a tropical depression right near the Philippines, and it will bring significant rainfall over the next 24 hours. The focal point of the storm has moved closer to Luzon, bringing flooding concerns into Manila and the surrounding areas. Those living from Cebu northward should be concerned with persistent rainfall during the overnight hours and throughout the day Friday. Those further south may be dealing with some windy conditions along with some rain, but the main concerns are in the central and northern regions of the country. Be on the lookout for the potential for rainfall up to 150 mm during the next 24 hours.
