HURRICANE ANDREW DISCUSSION NUMBER  31
NATIONAL WEATHER SERVICE MIAMI FL
11 PM EDT SUN AUG 23 1992


...CORRECTED TO SHOW NEWER RECON PRESSURE OF 937 MB...


THERE ARE NO SIGNIFIGANT CHANGES TO REPORT IN EITHER THE TRACK OR
INTENSITY OF ANDREW.  HOWEVER...MINOR STRUCTURAL EVOLUTION IS 
UNDERWAY IN THE CORE REGION WITH RECON CONTINUING TO REPORT A
CONCENTRIC EYEWALL STRUCTURE.  THIS DEVELOPMENT COINCIDES WITH A 
SLIGHT DECREASE IN THE STRENGTH OF THE INTERIOR EYEWALL...AND SO THE 
INTENSITY HAS BEEN LOWERED A LITTLE...TO 120 KT.  THIS IS ALSO 
CONSISTENT WITH THE LAST RECON FIX OF 937 MB.  NEVERTHELESS...THE 
HURRICANE WILL BE PASSING SOON OVER THE WARM GULF STREAM WATERS SO 
NOT MUCH ADDITIONAL WEAKENING IS EXPECTED...AND SOME RESTRENGHTENING 
REMAINS POSSIBLE AS WELL. 

THE TRACK FORECAST IS NEARLY IDENTICAL TO THE PREVIOUS COURSE.
LANDFALL IN THE MIAMI AREA AS A CATEGORY 4 HURRICANE AROUND 1200 UTC
IS BECOMING INCREASINGLY LIKELY.  THE HURRICANE IS STILL EXPECTED TO
WEAKEN A LITTLE IN ITS TRANSIT OVER THE FLORIDA PENINSULA. THE 72
HOUR POSITION IS THE SAME AS BEFORE.

NASSAU IN THE BAHAMAS REPORTED SUSTAINED 85 MPH WINDS WITH GUST TO
105 MPH NEAR 0030 UTC.

IN COORDINATION WITH NSSFC...A STATEMENT ABOUT THE POTENTIAL FOR 
ISOLATED TORNADOES HAS BEEN ADDED TO THE ADVISORIES.

LAND BASED RADAR FIXES SHOW THE EYE NOW...SO SUBSEQUENT ADVISORIES 
WILL BE ISSUED EVERY 2 HOURS.
