Nari (Santi) remains an average-sized tropical cyclone with a diameter of 610 kilometers across. The 24-hour rainfall accumulation near the center of Nari (Santi) is estimated to be extreme (320 mm).


TY Nari (Santi) is expected to continue moving westerly with an increase in forward speed during the next 24 hours...slowing down through 48 hours. On the forecast track, the core of Nari (Santi) will be traversing Nueva Ecija around midnight...and move across Tarlac and Pangasinan early Saturday morning. Nari (Santi) will then be emerging over the West Philippine Sea after crossing Zambales by Saturday morning. By Saturday evening through Sunday, the typhoon will exit the Philippine Area of Responsibility (PAR) - passing along the Scarborough (Panatag) Shoal in the West Philippine Sea.

TY Nari (Santi) is expected to weaken temporarily during the next 12 hours as it interacts with the mountain range of Sierra Madre and Zambales...and will reintensify once it reaches the West Philippine Sea during the next 24 to 48 hours. Advance Intensity Forecast (AIF) shows its 1-minute maximum sustained winds decreasing to 150 km/hr as it emerges across the West Philippine Sea.

The following is the summary of the 2-day forecast outlook and an extended 3-day forecast on this system:

SATURDAY EVENING: Weakens while emerging into the West Philippine Sea and exiting the PAR...about 440 km west-northwest of Iba, Zambales [11PM OCT 12: 15.4N 115.9E @ 160kph].
SUNDAY EVENING: Moving closer to Central Vietnam...reintensifies...about 410 km east-southeast of Da Nang, Vietnam [11PM OCT 13: 15.6N 112.0E @ 165kph].
MONDAY EVENING: Just along the coast of Central Vietnam...about 110 km east-southeast of Da Nang, Vietnam [11PM OCT 14: 15.8N 109.2E @ 165kph].

*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.
