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].
MONDAY MORNING:  Becomes a Category 2 Typhoon as it maintains its WNW movement toward Northern Luzon...about 407 km NE of Catanduanes, PH [8AM SEP 26: 16.0N 127.4E @ 165kph].
TUESDAY MORNING:  Becomes a Super Typhoon (Category 4) as it bears down the coast of Isabela-Cagayan Area...forward speed decreases...about 150 km ESE of Palanan Bay, Isabela [2AM SEP 27: 17.0 123.9E @ 240kph].

*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.


NESAT's (Pre-PEDRING) circulation continues to develop as it tracks into the Philippine Sea. Below is the summary of the storm's parts and its hazards affecting specific areas:

INNER RAINBANDS - over water (Philippine Sea)...not yet affecting any islands or major land areas. Tropical Storm Conditions w/ Tropical Storm Force Winds (62-117 kph) will be expected along these bands.
OUTER RAINBANDS - over water (Philippine Sea) longer affecting the Caroline Islands. Tropical Depression Conditions w/ moderate to strong winds (25-61 kph) will be expected along these bands (click here to know more about Rainbands).
24HR TOTAL RAINFALL ACCUMULATION - from 5 up to 100 mm (low to high rainfall) can be expected along areas affected by the outer & inner rainbands (see above)...with isolated amounts of 101 to 200 mm (high) along areas near the center of NESAT (Pre-PEDRING). (click to open NOAA's eTRaP graphic).
