3-DAY FORECAST OUTLOOK & ANALYSIS*
NESAT (PEDRING) is expected to maintain its general WNW track troughout the forecast period with some 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 Bicol Region tonight...and make landfall over Northern Aurora or just north of Casiguran by early Tuesday morning. NESAT will then cross the southern part of Northern Luzon - passing along Northern Quirino-Southern Isabela, Nueva Vizcaya, Benguet-Ifugao...and exit through La Union Tuesday afternoon. By Wednesday through Thursday, NESAT will be over the West Philippine Sea, leaving the Philippine Area of Responsibility (PAR) as it moves towards Hainan Island, Southern China.
Maximum Sustained Winds (1-min. avg) remain near 150 km/hr (80 knots) with higher gusts. NESAT is a Category 1 Typhoon on the Saffir-Simpson Tropical Cyclone Scale. Slight strengthening is still expected before the typhoon makes landfall over Northern Aurora. This system will gradually weaken just below typhoon strength as it traverses Luzon Tuesday...and will regain typhoon status upon moving back to sea by Wednesday.
Typhoon Force Winds (118 km/hr or more) extend outward up to 55 kilometers (30 nautical miles) from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 240 kilometers (130 nautical miles). NESAT is now a very large-sized tropical cyclone with a diameter of 905 kilometers (490 nautical miles). Meanwhile, land observation from the Typhoon2000.com Automated Weather Station in Naga City has been observing wind gust of 35 kph blowing from the WSW and barometer readings of 997.2 millibars. The Rainfall Accumulation over the station since 12AM is now at 173.2 mm, with average rain rate of 8 to 60 mm/hr (light to heavy).
The following is the summary of the 3-day forecast outlook on this system:
TUESDAY AFTERNOON: Downgraded to a Tropical Storm (TS), after crossing the mountainous terrain of Northern Luzon...just along the northern shores of La Union...about 33 km North of San Fernando, La Union [2PM SEP 27: 16.9N 120.3 @ 110kph].
WEDNESDAY AFTERNOON: Regains Typhoon status as it moves across the West Philippine Sea, moving out of the Philippine Area of Responsibility (PAR)...about 496 km West of Laoag City, Ilocos Norte [2PM SEP 28: 18.2N 115.9E @ 130kph].
THURSDAY AFTERNOON: Gaining strength slightly as it approaches the northern part of Hainan Island, along the coast of Southern China...about 210 km East of Qionghai, Hainan [2PM SEP 29: 19.3 112.5E @ 140kph].
