NESAT (Pre-PEDRING) is expected to continue moving on a straight-WNW motion throughout the forecast...with a slight fluctuation on its forward speed. On the forecast track, the center of the storm will move into the warm Philippine Sea tonight...and will be approaching the east coast of Northern Luzon, particularly Isabela & Cagayan on Tuesday.
Maximum Sustained Winds (1-min. avg) have increased to 75 km/hr (40 knots) with higher gusts. NESAT is a Tropical Storm (TS) on the Saffir-Simpson Tropical Cyclone Scale. Gradual strengthening is likely during the next couple of days...and NESAT could become a Typhoon Sunday afternoon.
Tropical Storm Force Winds (62-117 km/hr) extend outward up to 95 kilometers (50 nautical miles) from the center. NESAT is currently a small-sized tropical cyclone with a diameter of 260 kilometers (140 nautical miles). Additional increase on its circulation size is anticipated 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:
SUNDAY MORNING: Well within the PAR as it slightly accelerates...almost a Typhoon...about 824 km ENE of Catanduanes, PH [8AM SEP 25: 15.3N 131.8 @ 110kph].
