CHEBI (QUEENIE) EXITS THE PHILIPPINE AREA OF RESPONSIBILITY
(PAR) AS IT WEAKENS INTO A TROPICAL STORM...HEADS FOR HAINAN
ISLAND-GULF OF TONKIN AREA.

+ FORECAST OUTLOOK: CHEBI is expected to continue losing
strength as it encounters drier air from Southern China
and increasing upper level winds which disrupt the storm's
circulation. The 3 to 4-day forecast (Nov 16-17) shows
CHEBI turning towards the WNW and NW, making a passby over
the western coast of Hainan Island as a weakened depression.
 

+ EFFECTS: The storm's circulation remains over the South
China Sea and is not affecting any land areas at this time
.

Important Note: Please keep in mind that the above forecast
outlook, effects & current monsoon intensity, and tropical
cyclone watch changes every 06 to 12 hours!

REMARKS: 2 AM (18 GMT) 13 NOVEMBER POSITION: 15.2N 114.2E.
^TY Chebi is currently tracking westward under the steering
influence of the mid-level subtropical ridge (str), which,
according to the 12/00z 500mb analysis, is centered north-
east of Hainan Island, China. The 500 mb high center has
shifted eastward to its present position and has built
eastward over Taiwan over the past 24 hours in response to
a midlatitude ridge building into eastern China. Detailed
analysis shows that the northwestern periphery of the str
has weakened due to a series of shortwaves moving across
China and is expected to continue weakening and shifting
eastward as evident by height falls north of Vietnam.
This evolving pattern is key to the forecast through 72
hours and is supported by the majority of dynamic aids
which indicate a west-northwestward to northwestward
track along the southwestern periphery of the str. This
forecast is based on a consensus of the available dynamic
aids through 72 hours...(more info)

>> CHEBI {pronounced: je~bi}, meaning: A swallow. A small 
   bird with long wings and a forked tail that eats insects, 
   which visits Korea in Spring. Name contributed by: 
   Republic of Korea.
