TROPICAL STORM SEPAT (PRE-EGAY) NEWLY-FORMED OVER THE
EASTERN PHILIPPINE SEA...INTENSIFYING AS IT DRIFTS
SOUTHWESTWARD...NOW ENTERING THE PHILIPPINE AREA OF
RESPONSIBILITY (PAR)
...LIKELY TO BECOME A BIG THREATTO NORTHERN LUZON IN THE COMING DAYS.
+ FORECAST OUTLOOK: SEPAT is expected to continue
drifting Southwestward under weak steering flow, as
the high pressure ridge re-establishes North of this
system and will be the dominant steering factor
later in the week. SEPAT is likely to strengthen into
a full-blown typhoon tomorrow, Tuesday Aug 14. The 3
to 5-day forecast calls for SEPAT to accelerate WNW
over the Philippine Sea, in the direction of Batanes-
Southern Taiwan Area. It shall reach the coast of
Southeastern Taiwan on Saturday morning, Aug 17 as a
160-km/hr Category 2 Typhoon.
+ EFFECTS: SEPAT remains a small system with continued
development of its circulation near its center. It is
not yet affecting any land mass at this time as it
remains at sea.
+ CURRENT MONSOON INTENSITY: The Southwest (SW) Monsoon
may be re-activated by SEPAT, once it moves closer to
Northern Luzon in 3 to 5 days. Watch this section for
future monsoon updates.
