RAGASA IS SKIRTING AROUND 100 KILOMETRES TO THE SOUTH OF

OCCASIONALLY. THE HURRICANE SIGNAL, NO. 10 WILL REMAIN IN
FORCE FOR SOME TIME.
 
LOCAL WINDS ARE EXPECTED TO BECOME SOUTHEASTERLIES
GRADUALLY. MEMBERS OF THE PUBLIC SHOULD BE ON HIGH ALERT
AND BEWARE OF DESTRUCTIVE WINDS. LOCAL WEATHER WILL BE
PERSISTENTLY ADVERSE TODAY WITH FREQUENT HEAVY SQUALLY
SHOWERS AND THUNDERSTORMS. SEAS WILL BE PHENOMENAL WITH
SWELLS. THERE WILL BE OVERTOPPING WAVES OVER THE SHORELINE,
WHICH WILL BE PARTICULARLY SIGNIFICANT ALONG THE EASTERN
AND SOUTHERN COASTS. MEMBERS OF THE PUBLIC SHOULD STAY AWAY
FROM THE SHORELINE AND NOT ENGAGE IN WATER SPORTS.
