DISCUSSION
-----------------------------------
Cempaka... has continued its weakening trend as it remains
inland and crosses the border of the provinces of Guangdong/Guanxi.
A recent SSMIS pass and radar reflectivity data suggests the
core has completely collapsed, and now only consists of a few
convective/rain bands in the province of Guangdong. Dvorak analysis
is unavailable at this time due to the system's center being overland.
Due to the lack of surface observations and radar velocity data,
the initial intesity is decreased using the current trend of both
winds and pressure (55kts 989mb). Cempaka will continue its slow
trek through southern China, and in a few days is forecast to reemerge
over water in the South China Sea. The status and strength that
Cempaka will have as it traverses back over water remains uncertain,
therefore the future of impacts, steering, and intensification
in the South China Sea is highly variable.
