Weather Update as of 5pm - 31 May (2 LPA's spotted!)

We're keeping an eye on two (2) Low Pressure Areas East and West of the Philippines.

The first LPA has been showing signs of development. It is located some 465 km WNW of Laoag, Ilocos Norte or about 430 km SE of Hongkong.

The second LPA is still very weak but the sea surface temperature is favorable for development combined with low vertical wind shear in the area. It is about 1,400 km east of Mindanao or 520 km ENE of Koror, Palau.

We'll keep you posted for any signs of development. Thank you.

TYPHOON SONGDA (CHEDENG) as of 28 May @ 4:30pm (Final Advisory)

As of 4:30 this afternoon, Typhoon CHEDENG/SONGDA continued to move northeast and is now outside the Philippine Area of Responsibility. Forecast models show that this system is no longer a threat to the Philippines. SONGDA is moving NNE at 35 kph in the general direction of Okinawa, Japan. Threat to Okinawa, the Ryukyus and Southern Kyushu remains. SONGDA rapidly lost its strength now with wind gusts dropping to 195 kph. It is about 610 km NE of Basco, Batanes or 365 km East of Taipei, Taiwan or almost in the vicinity of the North Philippine Area of Responsibility (PAR). SONGDA's rainbands continue to leave the Batanes, Babuyan and Calayan Group of Islands and is affecting Taiwan. It shall approach in a few hours to the Okinawa Islands of Japan.

At 2am – 29 May, it shall be 210 km NE of Okinawa, Japan (outside the PAR) with wind gusts dropping to 155 kph.

On 29 May at 2pm, SONGDA is forecast to be 260 km SSE of Hiroshima, Japan. Wind gusts drops further to 130 kph.

AREAS HAVING PUBLIC STORM SIGNAL WARNING

ALL STORM SIGNALS NOW LOWERED:


***

FORECAST ANALYSIS AND EFFECTS:

SONGDA continues to pick up speed while gliding several hundred kilometers to the East of Taiwan. Deteriorating weather conditions shall prevail today over Taiwan. Very strong far-fetched waves are expected to hit the shorelines of Taiwan becoming apparent over Okinawa and The Ryukyus. Okinawa, The Ryukyus and Southern Kyushu shall also experience stormy weather (29 or 30 May) as SONGDA heads to the northeast over these Japanese Islands. Extra tropical transition is also expected beginning 30 May.

Expect rough to very rough sea conditions along these areas. FISHING BOATS AND OTHER SMALL SEACRAFTS ARE ADVISED NOT TO VENTURE OUT INTO THE SEA WHILE LARGER SEA VESSELS ARE ALERTED AGAINST BIG WAVES.

SONGDA shall also glide a few hundred kilometers north of Okinawa and Kadena Base and into Southern Kyushu. Once north of Okinawa, SONGDA shall encounter much cooler waters and rapid weakening is expected as the system continues to accelerate turning further to the Northeast. SONGDA is forecast to dissipate in the North Western Pacific Ocean by 01 June.

Forecast models generated different results in the extended forecasts (30 and 31 May) with some models bringing SONGDA over Japan while other models favoring an open water scenario just South of Japan and into the cooler portions of the North Western Pacific Ocean. Few other models even brought the system further north into the Sea of Japan. These inconsistencies are normal in a recurvature scenario.

Gradual weakening of sea waves is expected over Batanes, Calayan and Babuyan Island as the system moves away. The rest of the country shall experience improved weather condition as the Southwest Moonsoon weakens with some passing rain showers and thunderstorms mostly in the afternoon. The intertropical convergence zone shall continue to affect the archipelago as normal weather resumes.

P.S.
This will be the FINAL Advisory on this Tropical Disturbance. A new advisory will be issued once a new tropical disturbance becomes a threat to our country. Mabalos po.

***

FORECAST ANALYSIS AND EFFECTS:
The system started to accelerate as it moves north to north west over the past several hours. Threat to the Bicol Region diminishes as the High Pressure Ridge north of CHEDENG weakens. CHEDENG shall continue to move NW to NNW along the Philippine Sea and intensify and shall accelerate further beginning 27 May while moving to the East of Cagayan/Isabela and the Batanes Group of Islands.

Right now, CHEDENG is starting to pick-up speed and move away from Catanduanes. CHEDENG shall remain in the warm open waters and shall continue moving NNW towards the northern portion of the Philippine Sea. It shall maintain Super Typhoon strength (wind gusts at 305 kph) on May 27. A northward movement and a northeastern recurvature in the later part of the extended forecast is expected. CHEDENG shall glide hundreds of kilometers away to the east of the shorelines of Cagayan, Isabela and the Batanes Group of Islands sometime on 27 May.

Forecast models are still in good agreement with a NO LANDFALL Scenario for Typhoon SONGDA/CHEDENG. CHEDENG shall continue to accelerate later in the forecast between 27 to 31 May. Expect rains in LUZON and VISAYAS that could trigger flashfloods and winds. Strong to gale force winds (55 kph or higher) are expected to affect the Eastern seaboards of Luzon, Visayas and Mindanao becoming stronger in extreme Northern Luzon beginning 27 May.

Expect rough to very rough sea conditions along these areas. FISHING BOATS AND OTHER SMALL SEACRAFTS ARE ADVISED NOT TO VENTURE OUT INTO THE SEA WHILE LARGER SEA VESSELS ARE ALERTED AGAINST BIG WAVES.

Beginning 28 May, low ocean heat content shall weaken the system as it tracks out of the PAR. Extra tropical transition is also expected afterwards. CHEDENG shall be out of the country by 28 May. It is expected to recurve to the northeast missing Taiwan as an extra tropical storm system. Stay tuned for more updates.

P.S.
CHEDENG(Songda) is a strong and dangerous storm. If this hits land, it would be a deadly catastrophe. The public and the disaster coordinating councils concerned are advised to take appropriate actions and precautionary measures.

FORECAST ANALYSIS AND EFFECTS:
Based on this latest forecast from JTWC, the system shows a sharp turn to the north and a northeastern recurvature in the later part of the extended forecast period approaching very close to Basco, Batanes sometime on 27 May or early morning of 28 May, trekking also closely at Santa Ana, Palaui Island and Northern Cagayan Province. Expect stormy weather in these areas beginning 27 May.

Forecast models still shows SONGDA/CHEDENG gliding to the northeast of Northern Visayas and the Bicol Region. However, ECMWF now shows a more westerly track in the medium range forecast bringing CHEDENG's circulation closer to Northern Visayas and the Bicol region (26 May) and the rest of the eastern section of Luzon including Metro Manila (27 May). ECMWF also shows a direct Cagayan and Batanes Group of Islands landfall on 28 May. CHEDENG is also expected to accelerate later in the forecast between 26 to 29 May.

Overall, Landfall is still 50% possible along the northern coast of extreme Northern Luzon and 30% possible along the Bicol region as of this forecast.

The system is expected to enhance the southwest moonsoon once it hovers to the NE of Visayas, the Bicol region and the rest of Eastern Luzon. The rainbands of CHEDENG shall affect Northern Visayas, Northern Bicol, Isabela, Cagayan and the Batanes Group of Islands when this system approaches. Expect rains in LUZON and VISAYAS that could trigger flashfloods and winds sometime from 25 to 27 May. Strong to gale force winds (55 kph or higher) are expected to affect the Eastern seaboards of Luzon, Visayas and Mindanao becoming stronger in extreme Northern Luzon beginning 27 May.

Expect rough to very rough sea conditions along these areas. FISHING BOATS AND OTHER SMALL SEACRAFTS ARE ADVISED NOT TO VENTURE OUT INTO THE SEA WHILE LARGER SEA VESSELS ARE ALERTED AGAINST BIG WAVES.

CHEDENG shall be out of the country in the morning of 29 May. It is expected to recurve to the northeast missing Taiwan and shall head towards Okinawa and Western Honshu, Japan. Stay tuned for more updates.
