TY NOUL (DODONG) is expected to move generally northwestward at a normal speed for the next 24 hours...turning north-northwest to northward throughout the forecast period. On the forecast track, Noul will be approaching the eastern shores of Isabela Sunday morning (May 10) and shall make landfall near or over Palanan Bay Sunday afternoon. The typhoon shall then traverse Northeastern Isabela and Northern Cagayan passing very close to the east of Tuguegarao City by early Sunday evening...and could be over the Balintang Channel on Monday morning.

NOUL (DODONG) could still regain strength within the next 12 to 24 hours...and afterwards it will start to gradually weaken due to the frictional effect of the mountain ranges of Northeastern Luzon to its circulation upon making landfall. The Advance Intensity Forecast (AIF) shows its 10-minute maximum sustained winds increasing to 200 kph later tonight.

The following is the 3-day forecast outlook summary* for this system:

SUNDAY MORNING: Regain strength as it approaches the eastern coast of Isabela...about 95 km southeast of Palanan, Isabela [8AM MAY 10: 16.5N 123.1E @ 185kph]. Confidence Level: HIGH.
MONDAY MORNING: Turns to the north-northwest and north while emerging over the Balintang Channel...weakens after traversing Northeastern Luzon...about 135 km north-northeast of Pagudpud, Ilocos Norte [8AM MAY 11: 19.7N 121.1E @ 140kph]. Confidence Level: MEDIUM.
TUESDAY MORNING: Recurves sharply to the northeast and accelerates, across the Batanes Group of Islands...weakens significantly into a strong Tropical Storm (TS)...about 480 km northeast of Basco, Batanes [8AM MAY 12: 24.0N 124.7E @ 110kph]. Confidence Level: LOW.

Important Note: Please be reminded that the Forecast Outlook changes every 6 hours, and the Day 2 and 3 Forecast Track has an average error of 100 and 250 km respectively...while the wind speed forecast error, averages 35 kph per day. Therefore, a turn to the left or right of its future track and changes in its wind speed must be anticipated from time to time.

Important Note: Please keep in mind that the above hazards summary and forecast outlook changes every 6 to 12 hrs!
