WestPac Wx SE Asia Updates 16 April 2012




It has been a while since my last post here in the westernpacificweather (I didn’t even realize that it has already 1/2 a month since my last post.) The site has been kept busy with additional new author contributing to interesting and useful post for the public and I do hope that our visitor enjoy reading each and every weather news in the Western Pacific brought to you by the WestPac Wx Casters.

Back to the topic, the previous week for the South East Asia has been busy starting off with a magnitude 8.6 Richter Scale quakes in the Northern Sumatra sea that wreak havoc for the possible of a devastating Tsunami. It was exactly the same day where in Malaysia, we have our new King installed after the previous King completed His terms of 5 years. The new King was from the state of Kedah (My home state ruler to be precise). On that particular day, news received from my beloved sister telling me that she was actually shaking at home with my own personal computer monitor “dancing” front and back while she was having her movie. News about the quake where then spread quickly to the public by our affliate writer Weatherguy Adonis and our own NHK Caster and Meteorologist Robert Speta on this particular forum.

The next few days after the quake was never been quiet, low pressure started to surround the South East Asia region and Malaysia in particular has been receiving precipitation above average for the past few days. A record of 140mm of heavy rainfall has been recorded back in my home state (Kedah) and rainfall of 100mm to 150mm has been recorded in Perlis too. In the central region of Malaysia, flash flood has been reported in low lying area affecting villages. Water level in several river in Northern states of Malaysia is now above the warning stage posing flooding treat to areas within the river bank. At press, there has been an area where water level goes beyond danger level but yet, there hasn’t been a report of flooding from the authority. Rainfall has just started yet again at the current moment when I am completing this post.

The  radar imaginary from the Malaysia Meterological Department shows that some heavy rain clouds currently covering the upper air of Peninsula Malaysia and also the Borneo Island with several area in the coast of Brunei and Brunei mainland experiencing heavy rainfall. The weather agency in Malaysia has released heavy rain warning and scattered thunderstorm to persist for the coming few days in all the area across Malaysia. This will definitely meaning the potential and high possibility of flooding in some low lying area with such continuous heavy rainfall in the region.

Alongside with this update i attached together the NWP from Brunei weather agency. It is clearly visible that some heavy rainfall is going on in the region. The 2nd frame clearly illustrate that heavy rainfall is happening in the entire states with rainfall ranging from 20mm to 100mm per hour.

Meanwhile over the Singapore, weather seems clear except with some cloudy sky all over the state. The Singapore weather agency forecast an afternoon showers and thunderstorm in most of the area in the states for the coming 3 days.

A look at the latest run of the GFS model suggest that weather should improve and fair weather can be expected from next week and onwards.

For updates on other region, please do refer Rob’s and Pat’s post earlier today for the weather in PI, Japan, HK and China. Also, stay tuned for any interesting update by Don, the Weatherguy. And if you are a paid TV subscriber or an Apps user (Apple or Android), please do stay tuned with Rob’s weather update on NHK Newsline.

Finally, we would gladly announce that the very own forum for is now officially launched. Please join us here as part of the westernpacificweather family by signing up in the forum. The link for the forum is

That’s all from me right now. Stay safe and have a good day.

Philippines 3-Day Forecast | April 16, 2012

A tale of two weather conditions as Luzon is currently basking in clear weather and warm temperatures while some parts of Visayas and Mindanao are currently experiencing moderate rains. A quick update just north of the Philippines: a stationary front is bringing rain showers across Taiwan, Yaeyama Islands (Japan), SE China, and Hong Kong.

A nasty thunderstorms has actually formed just west of Hong Kong and moved southeastward, across the area and is currently dumping heavy rain along with thunder and strong winds. HKO has released a warning for strong winds reaching 130kph! Based on satellite and radar, thunderstorms in and around Hong Kong could last into the evening hours.

Forecast Graphic (NOT OFFICIAL!)

Meanwhile, moderate to heavy rains have dumped 100 to 150mm of rain across Mindanao today. Hinatuan in the eastern section recorded nearly 150mm and Cotabato in the central section of the island have, so far, recorded 50mm. Rains are also making their way into Visayas, with rains being reported in Panay and Negros Islands. Lighter amounts expected for Visayas unlike in Mindanao.

Heavy rains also affecting Western Mindanao, particularly around the Zamboanga Peninsula. Palawan also being affected by moderate rains as of the moment. All in all, these places could very well receive 100 to even 200mm of rain in the next two days. Rains should begin to die down late Wednesday but then another round of showers is forecast to affect the region later this week.

As mentioned above, much of Luzon is enjoying (or suffering depending on how you look at it) from clear weather and hot temperatures. In the afternoon hours, it is not uncommon for the temps to shoot up into 35 or 36C, especially in Manila. Cabanatuan even recorded 37C yesterday! Furthermore, the heat index is also right around the upper30s (even40C in some spots). Not much relief here in terms of rain forecast. Computer models not even giving 50mm in the next 3 days. There are slight chances for rain on Wednesday, however, especially around Northern Luzon but don’t expect too much here. If anything, majority of Luzon will remain dry and hot in the coming days.

We’ll have another update on Thursday, April 19.

16 APR Western Pacific Weather Video Update

Its monday yet again, here your outlook for the next several days and the coming week.

Areas of Northern Mindanoa are experiencing some heavy rainfall today, PAGASA has already issued a statement saying.


Weather Advisory #1 (10AM 4/16): Cloudy skies w/ widespread rains expected over Agusan Provinces, Surigao Provinces, Compostela Valley, Davao Oriental & Misamis Oriental due to the “Trough of Low Pressure Area”.¬†
Residents in low lying areas & along mountain slopes, particularly mining areas, are advised to be on alert for possible flashfloods & landslides.

The rest of Mindanao will have mostly cloudy skies w/ scattered rainshowers & thunderstorms.


This could spell for a potentially dangerous situation, yet for the rest of the Philippines it looks to be yet another hot one. Elsewhere Japan is seeing a low pressure system push through bringing light rain showers throughout the day and South East China could expect a new low forming up by the mid-part of the week. All the details are in the video.
