TYPHOON CHANCHU (CALOY) WEAKENS INTO A 220-KM/HR HOWLER, BUT STILL
A DESTRUCTIVE CATEGORY FOUR TYPHOON...NOW TAKES A DANGEROUS NORTH-

over the warm waters of the South China Sea with its outer rainbands
still covering the entire South China Sea and affecting Palawan
Island in Western Philippines. These rainbands will continue to
bring moderate to heavy rainfall with moderate to strong winds, and
could produce life-threatening flash floods and mudslides along
river banks, low-lying areas and mountain slopes over the affected
areas. Residents residing along the coastal beachfront areas of
Palawan, Western Luzon & Western Visayas are advised to seek higher

flooding from 13 to 18 feet can be expected along the path of
CHANCHU advising all sea vessels to remain at port and avoid
passing over it.


+ CURRENT MONSOON INTENSITY: This storm is still enhancing the
Southwest Monsoon bringing moderate to heavy rains along Western
sections of the Philippines. These rains may produce life-
