Intense Spring Storm Bears Down on Japan

A strong and deep Westerly Storm forming out of Eastern China is set to cruise in to Japan on Tuesday bringing Typhoon like winds at times. Typhoon like winds are only one of the aspects of this system as the central pressure is forecasted by the Japan MeteorologicalCAPPI 1.5km Rain rate : 2012/04/02 21:20 (KST) Service to get down as low as 996hpa by 00Z on the 4th. Gale force winds could extend out as far as 900nm from the center of  circulation at the height of this intense spring storm.

Already Korea is seeing heavy rains (radar image right. The areas shown in red on the radar though indicate up to 50mm an hour. That’s nearly half of the monthly average in Fukuoka where this storm will likely strike first in Japan.

Going in to Tuesday afternoon though this system will work its way North bringing high winds and gusty winds to Tokyo, so be sure to have an umbrella on tap as the foul weather begins to set in by the afternoon rush hour.

Good news is that most of Eastern Asia from China to Japan will see improved conditions by Wednesday afternoon as high pressure sets back in suppressing any stormy activity in the region.

The image below shows the 964hpa low at the height of its development. A video update will be posted by 15Z.

BREAKING: 95P No More, Grows Further Into Tropical Cyclone 18P/DAPHNE, Nears Fiji Island’s Western Territory

Nadi, Fiji Evacuates Its Citizens As Tropical Cyclone “18P/DAPHNE” Heads SSE’wards Towards The Coast

Iloilo City, Philippines, 02 April 2012, (0525Z)–Tenacious Tropical Disturbance “95P” now  a full-pledge Tropical Cyclone.  It traversed Vanuatu Islands, now accelerating towards Western edge of Fiji Island.

Yesterday, 01 April 2012, the Western Pacific had its eyes on Tropical Storm “02W/PAKHAR,” as it made landfall in Southern City of Vung Tau, Viet Nam just before 0620Z (1320PM-local), pummeled the coast with blinding rains and strong winds as it crashed onshore after it slightly intensified as indicated by a well-developed, “Eye” feature.  It fed on relatively warm waters off the coast of Viet Nam that bounds with the East China Sea.

Today, yet again, we are about to witness yet another feat in the current trend of increasingly intense “Tropical Cyclogenesis” across the South Pacific Basin with a potent storm, Tropical Cyclone “18P/DAPHNE,” as it heads ever dangerously closer to Western Fiji Island.  Already, the government officials in Capital Suva, has ordered massive evacuations of more than 7,000 of its citizens in Nadi, which is the Westernmost edge of the Island territory as torrential rains already caused flooding and could pose more threat to life and property.

Powerful Tropical System Heading Southwards

Tropical Cyclone “18P/DAPHNE,” was located to be at 19.2S-171.2E, or 663.5 km East-southeast of Nadi, Fiji at 2332Z (0732AM-PHL), with sustained wind reaching 65 km/hr (35 kt) and gusting near 93 km/hr (50 kt), with central pressure of 998 hPa, and currently traversing over warm waters, which should catapult it over a favourable “Ocean Heat Content” (OHC), but the “Shearing environment” could be an issue and considering that the system is tracking more South-southeastwards to generally Southward motion for the last 6 hrs.

I won’t be quite surprised if after this posting, the system should have increased in intensity, considering a great deal of adequate “Inflow” from the Western Quadrant of the system and evidently well supported by a surging moisture from the South of it.

Generally, this system should become “Extratropical,”  in the coming 3-4 days ahead of this forecast.

Having said that, we’ll see hot it deteriorates the by the time as system gradually negotiates on cooler waters in the days to come.  This is the cause and effect all tropical systems are made of, they tend to peak and they die altogether when the conditions become “Hostile,” for further tropical development.

The National Oceanic Atmospheric and Administration (NOAA) has issued warnings in consideration that the storm system could generate “Treacherous sea conditions,” as the cyclonic weather gets closer to Fiji Island later today.  Meteorologists in the agency also warned the coastal communities to be on alert for high surf conditions in the approach of the tempest and let it past.

The government in Suva also ordered its citizens to stay clear along the Western and Southern side of the Island territory and move to higher ground as rising sea levels whipped by Tropical Cyclone “18P/DAPHNE,” could endanger the coastal infrastructure.  “Storm Surges” are generated by these tropical systems and quite often if not mostly, this phenomena cause most deaths in a storm.

Pesistent Ill-effects Of La Niña Surges On

Look no further along the Eastern side of the Philippines where a huge area of “Drier Air Mass” persists, this is because of the prevalence of the weak “La Niña,” event through 2nd half of this year.  Other meteorologists have ruled out the connection between the La Niña Phenomenon and the occurrence of extreme weather conditions in the Asia-Pacific Region, and what is happening at the onset is the effects of “Climatic Changes,” as the most abused aspect of our environment. I am no skeptic but, I’d say, it ain’t through at all. We still feel its ill-effects to date and that’s my opinion where I stand firm to my principles that this adverse period of “Climatic” conditions should prevail well into the “Neutral” months starting on late June-August of 2012.

More details coming right up.  Keep it here, for the very latest on Tropical Updates from the Region and the rest of the world!

Pakhar Initial Damage and Videos

Reports coming in out of the South Eastern Coast of Vietnam indicate heavy road flooding in many areas with power out across sub-city areas to the East of Ho Chi Minh City but for the most part South East Vietnam has faired well considering the amount of rainfall that has fallen. The following comment was posted earlier today from WKshlei and gives a good description of the situation in his area.

The storm will pass mostly well north of the Mekong watershed — the northern quadrants are north of HCMC — but will significantly affect the Dong Nai river basin. I am in HCMC (Thao DIen, District 2) and have seen intense rain from 17:00-20:30, but it has slowed considerably in the last hour (it’s now 21:30). Briefly saw a rain warning for the coast and mountain areas E to NE of HCMC on Vietnamese TV tonight, but no interruption of programming — no one seems very concerned.
The Dong Nai has a big dam and reservoir (Tri An) but VN Meteo ( reports relatively low water, as would be expected at this time in the dry season (November – May/June), but there is only one (published) hydrometric station on the Dong Nai, and local flooding in and around HCMC could be significant — it is regularly in the wet season or at high tide when there are heavy rains

Meanwhile heavy showers sparked by Pakhar over Thailand brought flooding rains there with over 200 houses reported damaged due togusty winds and heavy rains in coastal communities south of Bangkok. If anyone has more information on this event out of Thailand we would be very humbled for you to share your information.

Pakhar’s Forecast at this time is to take it across the Cambodia border and then North bringing up to 150mm of rainfall in some locations along the way. Good news is it will continue to weaken and dissipate during its track north. The image to the right was produced by Weather Caster Pat showing the storms next motion to the North. Also you can see the flooding rains over the Gulf of Thailand.

If anyone has any photos or videos out of any of these effected areas as always you are welcomed to share.
