AREAS HAVING PUBLIC STORM SIGNAL WARNING

FORECAST ANALYSIS AND EFFECTS:
The system is still slow moving and was even stationary for several hours today before resuming on a NW track. CHEDENG is still a few hundred kilometers to the East of Samar. Its eye is now visible on several satellite images. Deteriorating weather is now being experienced in Samar, Leyte, Bicol including Northern Mindanao and becoming widespread in Central Visayas as the Southwest Moonsoon shall begin to be enhanced by this typhoon. CHEDENG shall remain in the open waters of the Philippines and shall continue moving NW towards the northern portion of the Philippine Sea. A sharp turn to the north and a northeastern recurvature in the later part of the extended forecast period is expected gliding hundreds of kilometers to the east of Isabela (26 or 27 May) and Batanes Group of Islands sometime on 27 May.

Majority of the forecast models still shows a NO LANDFALL Scenario for Typhoon SONGDA/CHEDENG. CHEDENG is also expected to accelerate later in the forecast between 27 to 30 May.

The system is now enhancing the southwest moonsoon while lingering to the NE of Visayas and the Bicol region. The rainbands of CHEDENG continues to affect Northern Visayas, and Bicol. 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 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.
