...TROPICAL STORM WARNING REMAINS IN EFFECT...
...TYPHOON WATCH REMAINS IN EFFECT...

...NEW INFORMATION...
THE 24 HOUR PRESSURE FALL AT SAIPAN AIRPORT WAS 7.5 MB. PRESSURE
FALLS ARE LIKELY EVEN LARGER AT ISLANDS NORTH OF SAIPAN. THIS
SHOWS NOT ONLY THE CONTINUING APPROACH OF CHOI-WAN BUT ALSO ITS
CONTINUING TREND FOR INTENSIFICATION. IT HAS BEEN SEVERAL YEARS
SINCE A SIGNIFICANT TYPHOON HAS STRUCK THE MARIANAS. ESPECIALLY
FOR ALAMAGAN...BEWARE OF A SUDDEN DROP IN WINDS. THIS MAY BE THE
EYE RATHER THAN THE END OF THE STORM. IN THIS CASE WINDS WILL
RETURN JUST AS SUDDENLY FROM THE OPPOSITE DIRECTION. CHOI-WAN WILL
PASS VERY CLOSE TO ALAMAGAN TUESDAY AFTERNOON.

...PRECAUTIONARY/PREPAREDNESS ACTIONS...
FINAL PREPARATIONS TO PROTECT LIFE AND PROPERTY SHOULD BE
COMPLETED BEFORE CONDITIONS DETERIORATE IN THE NEXT FEW HOURS.
THE ONSET OF STRONG GUSTY WINDS AND HEAVY RAINS CAN CAUSE OUTSIDE
ACTIVITIES TO BECOME DANGEROUS. SECURE LOOSE OUTDOOR OBJECTS WHICH
CAN BE BLOWN AROUND. IF YOU LIVE IN A TIN-ROOF HOME...LEAVE IT
FOR MORE SUBSTANTIAL SHELTER. SMALL CRAFT SHOULD ALREADY BE
SECURED.

&&

SUSTAINED TROPICAL STORM-FORCE WINDS WILL OCCUR BETWEEN MIDNIGHT

ALAMAGAN AND AGRIHAN...WIND DIRECTIONS WILL BE NORTHEAST TONIGHT
AND TUESDAY MORNING...TURN EAST TUESDAY AFTERNOON THEN SHIFT TO
SOUTHEAST TUESDAY NIGHT. TROPICAL STORM FORCE WINDS ARE EXPECTED
ON TINIAN...SAIPAN...ALAMAGAN AND AGRIHAN. TYPHOON FORCE WINDS
ARE A DISTINCT LIKELIHOOD ON ALAMAGAN TUESDAY AFTERNOON AND
EVENING.

...STORM SURGE AND STORM TIDE...
STORM SURGE AND INUNDATION OF 3 TO 5 FEET ABOVE HIGH TIDE IS
POSSIBLE AS CHOI-WAN PASSES...WITH HAZARDOUS SURF OF 8 TO 12 FEET
ALONG WEST FACING REEFS THIS EVENING...BUILDING TO 13 TO 16 FEET
