REMARKS:
262100Z POSITION NEAR 12.3N 90.7E.
TROPICAL CYCLONE (TC) 02B (MALA), LOCATED APPROXIMATELY 425 NM
SOUTHWEST OF YANGON, MYANMAR, HAS TRACKED NORTHWARD AT 04 KNOTS
OVER THE PAST 06 HOURS. ANIMATED INFRARED SATELLITE IMAGERY AND
UPPER AIR ANALYSIS INDICATE THAT TC 02B REMAINS IN AN AREA OF
MODERATE SOUTHEASTERLY VERTICAL WIND SHEAR. A BUILDING LOW TO
MID LEVEL STEERING RIDGE OVER SOUTHEAST ASIA COUPLED WITH MID-
LATITUDE TROUGHING OVER THE NORTHERN BAY OF BENGAL WILL MAINTAIN
TC 02B ON A NORTH-NORTHEASTWARD TRACK. A CONTINUED ENVIRONMENT
OF MODERATE VERTICAL WIND SHEAR WILL LIMIT CLIMATOLOGICAL
INTENSIFICATION THROUGH THE FORECAST PERIOD. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 261800Z IS 21 FEET. NEXT WARNINGS AT 270900Z AND
272100Z.//
