WTPA42 PHNL 180900
HURRICANE DORA DISCUSSION NUMBER  50
NATIONAL WEATHER SERVICE HONOLULU HI
11 PM HST TUE AUG 17 1999
 
DORA PASSED SOUTH OF JOHNSTON ATOLL AT ABOUT 06Z MOVING WEST TOWARD
THE DATELINE. THE STORM CENTER WAS FAR ENOUGH FROM JOHNSTON TO SPARE
THE ATOLL FROM ANY DAMAGING WIND OR SURF. THE SURF LIKELY WAS THE
MOST SEVERE ASPECT OF THIS STORM. HOWEVER THE SURF BREAKS ON THE
REEF FAR AWAY FROM INHABITED AREAS. THUS DORA'S EFFECTS ON JOHNSTON
WERE MILD AS COMPARED TO HURRICANE JOHN OF 1994.  DORA REMAINS
RATHER WEAK AT THIS TIME AND BARELY QUALIFIES AS A HURRICANE. THERE
IS STILL A CHANCE IT COULD REINTENSIFY BUT LIKELY NOT DURING THE
NEXT DAY OR TWO.  INITIAL MOTION IS 270/17 KT. THE OFFICIAL TRACK IS
SIMILAR TO GFDL AND THE PREVIOUS TRACK.
