MANGKHUT'S INTENSE RAINBANDS ARE AFFECTING HONG KONG,

ALREADY UNDER STRAIN FROM WIND PRESSURE, WILL SHATTER
EASILY IF HIT BY A FLYING OBJECT. MAKE SURE YOU HAVE A SAFE
PLACE TO SHELTER. YOU SHOULD ONLY FIX BROKEN WINDOWS AND
DOORS WHEN THERE IS NO DANGER IN DOING SO.
 
3. WITH CHANGE IN WIND DIRECTION, VIOLENT WINDS WILL COME
FROM A DIFFERENT DIRECTION. REMAIN WHERE YOU ARE IF
PROTECTED AND BE PREPARED FOR DESTRUCTIVE WINDS AND THE
CHANGE IN WIND DIRECTIONS.
 
4. PEOPLE OUTDOORS SHOULD FIND A SAFE PLACE NOW AND REMAIN
THERE UNTIL THE DANGER IS OVER.
