Tropical Storm Tembin (Vinta) starting to bring heavy rain into SE Philippines

Good afternoon from the Western Pacific Weather team.

A tropical depression east of the Philippines has intensified into a tropical storm named Tembin (Vinta in PAGASA nomenclature), and it is already starting to bring heavy rainfall into the area. As previously mentioned, the greatest threat with this system has been and will be the heavy rainfall. The winds are expected to remain at tropical storm force going through Friday and the weekend, but residents need to be prepared as rainfall will likely lead to flooding and landslides.

Those in Visayas along with all of Mindanao should be bracing for this system as the impacts will be greatest for those regions. Signal alerts have been issued for the following locations (as of 1400 on 21 December 2017):

Signal 2: Mindanao – Surigao del Norte Incl. Siargao Islands, Surigao del Sur, Agusan del Norte, Agusan del Sur, and Northern Davao Oriental
Signal 1:
Mindanao –┬áDinagat Island, Camiguin, Misamis Oriental, Misamis Occidental, Bukidnon, Lanao del Norte, Lanao del Sur, North Cotabato, Maguindanao, Rest of Davao Oriental, Northern Davao del Sur, Compostela Valley, Davao del Norte, and Zamboanga del Sur
Visayas –┬áSouthern Leyte, southern portion of Leyte, Southern Cebu, Siquijor, and Bohol

High waves will also be of concern for the coastal areas, and so for those of you living near the waters should seek higher ground, especially for those along the eastern and northern side of the islands in Visayas and Mindanao.

Here’s meteorologist Robert Speta with his video analysis of the storm:

Slow-moving tropical depression to bring plenty of rain to Mindanao

Good evening from the Western Pacific Weather team.

While Kai-tak is continuing to move further away from the Philippines, a tropical depression east of the Philippines is heading its way toward Mindanao. The slow-moving system is currently drifting to the west. Sea surface temperatures are warm enough to aid in the storm’s moisture potential, but there are still factors, including some wind shear, that’s preventing the system from intensifying for the moment.

Nevertheless, it is going to be a wet weekend for those in Mindanao. Some will see up to 250 mm of rain, and that could lead to flooding and landslides. Residents should prepare for a rough weekend and possibly through the first part of next week.

Other areas to the north of Mindanao are likely to not see any direct impact from the depression, but there is a chance that some of that rain may impact Visayas.

On a side note, Kai-tak will bring some significant rain into certain portions of southern Vietnam. Rain totals may hit up to 100 mm. Residents should be prepared as this storm, while not making landfall, could still run plenty of rain into the region.

Kai-tak drawing rain, while another low pressure approaches Mindanao

Good afternoon from the Western Pacific Weather team.

Tropical Storm Kai-tak (Urduja) continues to push to the west away from the Philippines, and while it is over the open waters, it is still impacting nearby areas of land. The system is helping to enhance the rain over Luzon. Some locations are still seeing high amounts of rainfall with little movement, leading to concerns of more flooding.

Meanwhile, those in Vietnam need to be on the lookout for rain over the next couple of days. Those on the southern coastline will likely see some rain into Wednesday, and some of the rain could be heavy. Therefore, those living in the region should be prepared to move further inland should that need arise.

Invest 97W is still simply a low pressure to the east of Mindanao. That being said, while the system is looking less likely to develop into something tropical, it is looking more likely that it will bring heavy rainfall into both Mindanao and Visayas as we head into Christmas weekend. Both the GFS and the Euro models are indicating the enhancement of moisture for the central and northern areas of the Philippines, while the southern areas will see the low pressure system passing over the region. It is becoming more likely that Mindanao will see a soaker of a storm for the weekend.
