FORECAST OUTLOOK / POSITIONS

3-DAY FORECAST OUTLOOK & ANALYSIS*

NESAT (PEDRING) is expected to start moving WNW troughout the forecast period with a slight decrease on its forward speed. On the forecast track, the center of the typhoon will pass more or less 250 km to the north of Camarines Sur tomorrow afternoon through the evening.

Maximum Sustained Winds (1-min. avg) have increased to near 130 km/hr (70 knots) with higher gusts. NESAT is a Category 1 Typhoon on the Saffir-Simpson Tropical Cyclone Scale. Gradual strengthening will continue during the next couple of days...and NESAT could be near-Super Typhoon strength before it makes landfall early Tuesday.

Typhoon Force Winds (118 km/hr or more) extend outward up to 35 kilometers (20 nautical miles) from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 140 kilometers (75 nautical miles). NESAT remains an average-sized tropical cyclone with a diameter of 555 kilometers (300 nautical miles). Possible increase in its circulation size is likely as the system moves into the warm Philippine Sea in the next couple of days.

The following is the summary of the 3-day forecast outlook on this system:

MONDAY AFTERNOON:  Intensifies to a Category 3 Typhoon as it passes to the north of Bicol Region...about 233 km NNE of Naga City, PH [2PM SEP 26: 15.4N 124.3 @ 205kph].

TUESDAY AFTERNOON:  Weakened temporarily to Category 1 as it traverses Luzon...just along the West Coast of La Union...about 24 km WNW of San Fernando, La Union [2PM SEP 27: 16.7N 120.1E @ 140kph].

WEDNESDAY AFTERNOON:  Re-intensifies over the West Philippine Sea (aka. South China Sea)...exits PAR...about 460 km WNW of Vigan City, Ilocos Sur, PH [2PM SEP 28: 18.2 116.1E @ 150kph].

**Alternate Forecast Scenario (AFS): There is a possibility that NESAT (PEDRING) will continue moving Westward and make landfall over Northern Quezon & Southern Aurora instead...cutting across Central Luzon...and exiting along Pangasinan-Northern Zambales Area. This scenario may happen if the High Pressure Steering Ridge northeast of the typhoon will not weaken & extends westward.

*Please be reminded that the Forecast Outlook changes every 6 hours, and the Day 3 Forecast Track have an average error of 250 km...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.
