DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
AT 400 PM CDT...2100 UTC...THE EYE OF HURRICANE ALEX WAS LOCATED
BY A RECONNAISSANCE AIRCRAFT AND NATIONAL WEATHER SERVICE RADAR FROM
BROWNSVILLE NEAR LATITUDE 24.5 NORTH...LONGITUDE 96.8 WEST. ALEX
HAS INCREASED ITS FORWARD SPEED AND IS MOVING TOWARD THE WEST NEAR
13 MPH...20 KM/HR. THIS GENERAL MOTION IS EXPECTED TO CONTINUE
UNTIL LANDFALL IN NORTHEASTERN MEXICO TONIGHT. 
 
MAXIMUM SUSTAINED WINDS HAVE INCREASED TO NEAR 90 MPH...150
KM/HR...WITH HIGHER GUSTS.  ALEX IS A CATEGORY ONE HURRICANE ON THE
SAFFIR-SIMPSON HURRICANE WIND SCALE.  SOME ADDITIONAL STRENGTHENING
IS POSSIBLE DURING THE NEXT FEW HOURS BEFORE LANDFALL. A GRADUAL
WEAKENING IS FORECAST AFTER THE CENTER CROSSES THE COASTLINE. 
 
ALEX IS A LARGE CYCLONE AND HURRICANE FORCE WINDS EXTEND OUTWARD UP
TO 70 MILES...110 KM...FROM THE CENTER...AND TROPICAL STORM FORCE
WINDS EXTEND OUTWARD UP TO 205 MILES...335 KM PRIMARILY TO THE
NORTHEAST OF THE CENTER. A MEXICAN NAVY AUTOMATED STATION IN

LATEST MINIMUM CENTRAL PRESSURE REPORTED BY AN AIR FORCE
RECONNAISSANCE AIRCRAFT WAS 959 MB...28.32 INCHES.
 
 
HAZARDS AFFECTING LAND
----------------------
RAINFALL...ALEX IS EXPECTED TO PRODUCE TOTAL RAINFALL ACCUMULATIONS
OF 6 TO 12 INCHES OVER PORTIONS OF NORTHEASTERN MEXICO AND SOUTHERN
TEXAS...WITH ISOLATED MAXIMUM AMOUNTS OF 20 INCHES.  THESE RAINS
COULD CAUSE LIFE-THREATENING FLASH FLOODS AND MUD SLIDES...
ESPECIALLY IN MOUNTAINOUS TERRAIN.  THE BROWNSVILLE DOPPLER RADAR
SHOWS NUMEROUS RAINBANDS ASSOCIATED WITH ALEX AFFECTING THE
SOUTHERN TEXAS AND NORTHEASTERN MEXICO COASTS.
 
WIND...HURRICANE CONDITIONS ARE EXPECTED TO REACH THE COAST WITHIN
THE HURRICANE WARNING AREA TONIGHT. HOWEVER...TROPICAL STORM WINDS
ARE ALREADY AFFECTING PORTIONS OF THE COAST.
 
STORM SURGE...A DANGEROUS STORM TIDE WILL RAISE WATER LEVELS BY
AS MUCH AS 4 TO 6 FEET ABOVE GROUND LEVEL ALONG THE IMMEDIATE COAST
TO THE NORTH OF WHERE THE CENTER MAKES LANDFALL. THE WATER COULD
PENETRATE INLAND AS FAR AS SEVERAL MILES FROM THE SHORE WITH DEPTH
GENERALLY DECREASING AS THE STORM TIDE MOVES INLAND.  NEAR THE
COAST...THE SURGE WILL BE ACCOMPANIED BY LARGE AND DESTRUCTIVE
WAVES.

SOUTHERN TEXAS TONIGHT.
