Rammasun will then move into Southern Luzon and impact the area including Metro Manila by tomorrow afternoon and into the evening hours. Rammasun should then exit into the South China Sea (West Philippine Sea) by Wednesday morning. We’re expecting

Signal Force Warnings

200 to as much as 300mm of rain to fall over the next 24 hours so the flooding and landslides will be very high especially in low-lying and mountainous areas and also near bodies of water.

Please heed the warnings of your local officials for the latest warnings. And if there are any evacuations in your area, please follow them, stay safe!

As we often say here at westpacwx. If conditions look bad outside and seem dangerous. They probably area.

Impacts on Manila

The city is noctorios for being flood prone and this storm will be no different. Heavy rainfall on Tuesday night through Wednesday will bring flash flooding across the Metro area likely stopping traffic for most of the city.

Furthermore strong westerly winds could bring a coastal storm surge around Roxas BLVD and much the immediate coastline.  If you are in an area that often floods be sure to make proper preparations to avoid casualties first then property.

Should you Prepare?


Yes if you are in the cone of error be ready for possible flooding and even the threat of winds lifting light objects especially along the eastern seaboards. As our partner Karen from K Weather said.  “PAGASA says this may be stronger than Milenyo. No harm in heeding their warning and preparing for a strong typhoon. If it doesn’t happen, well and good.”

As we know storms can be very deadly in the Philippines. But more often than not especially with some of the weak storms we hear of people who died because they did something foolish like swim through flood waters or did not take the storm seriously. Also be prepared and as always stay safe!
