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.

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

Flooding in Central Malaysia 31 March 2012

The central region of Malaysia was hit by 2 flash flood in the duration of 3 days total up 3 flash flood in 2 weeks time. The area affected was the city of Klang located in the Klang Valley close to the capital of Malaysia, Kuala Lumpur.

The first flash flood hit the Southern Part of the city on 27 of March 2012 and yesterday, flash flood once again hitting the area covering up almost 60% of the city causing 100 thousand citizens in the area affected. The first flash flood hit soon after the 2 hour heavy downpour. It is reported that two of the main sluice allowing river water to flow to the sea was malfunctioning therefore resulting the start of the flash flood on the 27th of March.

Not even 72 hours after the first wave of flood hits, heavy rainfall starts again. This time the rain lasted for 6 hours beginning 1am in the morning local time and ends at 7am in the morning local time. The accumulated rainfall raises from 42mm to 90mm in the duration of 6 hours causing rivers and drain to be filled up with rain water thus resulting flash flood. The area affected in the second wave of flash flood includes a satellite city and industrial area causing millions of losses as the area of Klang city is a very highly populated metropolitan city. Below I attached some of the photo in the flood affected area. These photo are courtesy of a local Malaysian chinese newspaper (Guang Ming Daily).

Invest 96w and SE Asia Weather Updates 28 Mac 2012

Currently we have a tropical low lingering in the South China Sea, Invest 96w as reported by Rob earlier (See HERE) has been stationary for the last couples of hour. The possibility to strengthen into a tropical cyclone in the next 24 to 48 hour remains medium. Most of the model forecast that this area of low pressure will remain stationary before moving north west to the coast of Vietnam in the coming few days until next week. (Refer HERE for GFS model and HERE for NoGaps model). Meanwhile, the image from the Thailand Meteorological Department above indicating that there are several area of low pressure on both the land and the water.

The Malaysia Meteorological Department, in conjunction with Invest 96w has issued a Third Category Strong Wind and Rough Sea Warning  over the waters off Condore, Reef North & Layang-Layang with expected winds from 60kmph and sea waves above 4.5 metres. The warning remains until the 3rd of April 2012. A Second Category Strong Wind and Rough Sea Warning was issued over the waters off Kelantan, Terengganu, Pahang, East Johore, Sarawak, FT Labuan, Sabah (Interior, West Coast, Kudat), Tioman, Bunguran, Samui, Reef South & Palawan are expected to continue until Tuesday, 3rd April 2012. Strong West/Southwesterly Winds with speed up to 60kmph and sea waves of 4.5 metres is expected over the area.

And finally, overall in the region it will be a wet weather specifically over the Borneo Island we should see most of the area with showers and thunderstorm inclusive of Brunei while over in Peninsula Malaysia, scattered thunderstorm and isolated rain is expected in the central region to the southern region specifically the area of Kuala Lumpur, Southern Perak and Pahang, Negeri Sembilan and Malacca. Meanwhile in Singapore, the Singapore Weather Agency forecast morning and afternoon showers in most part of the country and fair weather across the area in the evening. Far to the east in the Philippine specifically the Southern Luzon, we have a system picking up but none of the agency has classified this system into any development. However, do expect some heavy rainfall over the area and also watch out for rough sea and strong winds over the coastal area.

That’s all from me right now. Have a good day and stay safe.

Heavy rainfall and Flood in Malaysia (Updates) 08/09 March 2012

It has been a tough day for fellow Malaysians especially in the West Peninsula of Malaysia. Heavy rainfall has been recorded in almost the entire West Peninsula from as north as the states of Perlis until the south of the states of Johor. The following images are obtained from the Drainage and Irrigation Department of Malaysia for the states of Selangor and also Federal Territory of Kuala Lumpur. It is clearly visible that these central area of Peninsula Malaysia is experiencing heavy rain fall ranging from 60mm to over 180mm in the duration of 48 hours. The Malaysian Meterological Department had also issued a Orange Stage (Second Category) heavy rainfall warning for this area and as updated earlier, much of the metropolitan city is currently under water due to flashflood by this heavy rainfall in approximately 3 – 4 hours of none stop heavy rain. This heavy precipitation condition is expected to continue until early Friday morning. The current episode of heavy rainfall in the Peninsula Malaysia is caused by the Madden-Julian Oscillation. Have more read on it HERE

Aside from the Federal Territory, other states are experiencing the similar weather. Over the northern region, the states of Perlis and Kedah has been experiencing some heavy precipitation over the past 48 hours
resulting some flashflood over
several low lying area. Several main river in the states has been reported to be bursting affecting area around the river bank to be flooded but as the sky is clear today though it is cloudy, the water level is expected to recede further thus not wreaking any flood havoc that will further aggravate the situation.
