REMARKS:
040300Z7 POSITION NEAR 16.3N0 151.2E9.
TYPHOON (TY) 22W (SAOMAI), LOCATED ABOUT 350 NM EAST-NORTHEAST OF 
SAIPAN, MARIANA ISLANDS, HAS TRACKED WEST-NORTHWESTWARD AT 11 KNOTS 
OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 032330Z1 
VISIBLE AND INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS 
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 55 AND 65 KNOTS. 
ANIMATED VISIBLE SATELLITE IMAGERY DEPICTS INCREASING ORGANIZATION 
WITH A 120-NM DIAMETER CENTRAL DENSE OVERCAST. A 032318Z7 SPECIAL 
SENSOR MICROWAVE IMAGER PASS DEPICTS DEEP CONVECTION SOUTH OF THE 
LOW-LEVEL CIRCULATION CENTER (LLCC) WITH CONVECTIVE BANDS NORTH AND 
SOUTH OF THE LLCC. ANIMATED WATER VAPOR IMAGERY DEPICTS GOOD OUTFLOW 
OVER THE SYSTEM. THE MID LEVEL HIGH CENTERED NORTH OF WAKE ISLAND 
WITH ASSOCIATED RIDGE EXTENDING WEST OVER IWO JIMA IS EXPECTED TO 
INTERACT WITH A TROPICAL UPPER TROPOSPHERIC LOW, REFLECTING IN THE 
MID-LEVELS SOUTH OF IWO JIMA, BY MID PERIOD. THIS WILL CAUSE TY 22W 
TO TURN INCREASINGLY NORTHWESTWARD AFTER THE 24-HOUR PERIOD. TY 22W 
IS FORECAST TO INTENSIFY DURING THE FORECAST PERIOD. MAXIMUM 
SIGNIFICANT WAVE HEIGHT AT 040000Z4 IS 17 FEET. REFER TO WWPW30 RJTX 
FOR ADDITIONAL SEA HEIGHT INFORMATION. NEXT WARNINGS AT 040900Z3 
(DTG 040751Z7), 041500Z0 (DTG 041351Z4), 042100Z7 (DTG 041951Z0) AND
050300Z8 (DTG 050151Z2).//
