Typhoon Kammuri / Tisoy Nearing Landfall

Kammuri or locally known as Tisoy has slowly attempted to gain strength today but still remains a somewhat disorganized cluster of storms. Prior to landfall though it does still look like a Cat 1 or Two at landfall with the threat of Storm Surge and heavy rains. Some areas as much as 2 ft or about 600mm. This may not be a “Haiyan” type setup since it’s not a super typhoon by any means but, it still is going to be a dangerous storm for some. Here are my latest thoughts.

Be sure to check PAGASA for the latest updates on the warnings.


Possible Impacts


A damaging wind threat of course exist with this storm. According to JMA could come on shore in southern to Central Luzon with winds gusting over 130kts. Yet with sea surface temperatures remaining over 30 degrees in the Philippine sea there is a potential of strengthening prior to landfall making winds even higher. Any structures along the coast not make of concrete could suffer wind damage.

Storm Surge

There are plenty of bays in inlets along the south east of coast of Luzon that could help trigger a funneling effect as Kammuri moves near the shore. If that takes place a significant storm surge may accompany Kammuri. Plus as winds shift from the west across Manila bay a coastal storm surge in the capitol may also take place on Tuesday. Places like Roxas BLVD that are known for flooding will likely flood.


As with any tropical system making landfall a lot of rain will come with it. The storm may slow down a bit after coming on shore which will result in high amounts of rain. According to latest GFS models upwards of 400-500mm is possible. That is enough to trigger local flooding and landslides.

Organizers at the South East Asian Games say they are prepared for the storms impacts. They did note some events could be delayed or cancelled while indoor events are expected to go on as normal. The games start November 30th and run through December 11th.
