TYPHOON MAN-YI {pronounced as "Mun-yi"} (BEBENG) GAINED
MORE STRENGTH AS IT ENTERS THE PHILIPPINE AREA OF RES-
PONSIBILITY (PAR)...NOW LOCALLY NAMED "BEBENG"
...MOVING
FASTER TOWARDS THE NORTHWEST.


+ FORECAST OUTLOOK: MAN-YI is expected to continue in-
tensifying as it traverses the Northern Philippine Sea
& shall move in a generally NW'ly track for the next 2
days. Majority of the computer forecast models still
shows a path towards Okinawa-Southern Japan area this
weekend (Jul 14 to 16). The 3 to 5-day long-range fore-
cast (Jul 14 to 16) shows the system becoming a Category
4 Typhoon (215 km/hr) as it recurves Northward, passing
very close to the East of Okinawa, Japan this early Sa-
turday morning, Jul 13 (around 12 AM HK Time) and shall
accelerate ENE passing onshore along the beachfront
areas of Kyushu, Shikoku & Honshu. By 2 AM HK Time, Sun-
day (Jul 15), MAN-YI is forecast to pass very close to
Tokyo, Japan - approx. 110 km to the South


+ EFFECTS: MAN-YI's over-all circulation remains large
and continues to cover most of the Philippine Sea and
portions of Micronesia. Overcast skies with moderate
to heavy rains & gale-force winds of 55-65 km/hr is
expected along the affected areas
.

+ MONSOON INTENSITY FORECAST: The advance 2 to 3-day
forecast continues to show a surge of moderate to strong
Southwest (SW) Monsoon which is likely to affect the Phi-
lippines beginning today July 11 extending thru the week-
end (Thu to Sun, Jul 12-15) - as the large Typhoon MAN-YI
enhances the Monsoon wind system
.
Cloudy skies with inter-
mittent passing rains or thunderstorms can be expected
across the country w/ SW'ly winds of 30 km/hr or higher,
becoming more intense along the Western sections of the
Philippines including Metro Manila & Subic Bay
. Mudslides
and flooding is likely along river banks, low-lying &
flood-prone areas of Western Philippines. Stay tuned for
more Monsoon updates in the coming hours
.

+ TROPICAL CYCLONE WATCH: N/A.


Important Note: Please keep in mind that the above forecast
outlook, effects & current monsoon intensity, and tropical
