...NEW INFORMATION...
THE EMERGENCY MANAGEMENT OFFICE IN SAIPAN HAS DECLARED TROPICAL
STORM CONDITION ONE FOR ISLANDS IN THE CNMI FROM TINIAN NORTHWARD
TO AGRIHAN. THIS INCLUDES SAIPAN.

CHOI-WAN IS NOW A TYPHOON. THE VERY SLOW MOVEMENT BY THE TYPHOON
OVER THE PAST SEVERAL HOURS IS CAUSE FOR CONCERN...BECAUSE SUDDEN
CHANGES IN DIRECTION ARE USUALLY FOLLOWED BY ERRATIC MOVEMENT. IT
IS POSSIBLE THE TYPHOON WILL PASS CLOSER TO SAIPAN THAN FORECAST.
HOWEVER...TYPHOON FORCE WINDS ARE NOT EXPECTED TO IMPACT TINIAN
AND SAIPAN UNLESS A MAJOR CHANGE IN FORWARD MOTION OCCURS.
FORECAST MODELS CONTINUE TO INDICATE THE TYPHOON WILL PASS
THROUGH THE NORTHERN MARIANAS NEAR ANATAHAN LATER TONIGHT.

...PRECAUTIONARY/PREPAREDNESS ACTIONS...
FOR TINIAN...SAIPAN...AGRIHAN AND ALAMAGAN...NOW IS THE TIME TO
RUSH TO COMPLETION PREPARATIONS FOR THE PROTECTION OF LIFE AND

RADIO OR OTHER LOCAL NEWS OUTLETS FOR OFFICIAL STORM INFORMATION.
LISTEN FOR POSSIBLE CHANGES TO THE FORECAST AS DESCRIBED BY YOUR
LOCAL NATIONAL WEATHER SERVICE OFFICE AND LOCAL EMERGENCY
MANAGEMENT.
