TROPICAL CYCLONE (TC) 03B LOCATED APPROXIMATELY 300 NM SOUTH-
SOUTHWEST OF CALCUTTA, INDIA, HAS TRACKED NORTH-NORTHEASTWARD AT 15
KNOTS OVER THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON

IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 30 AND 35
KNOTS. ANIMATED INFRARED IMAGERY INDICATES GOOD OUTFLOW REMAINS AS
THE SYSTEM REACHES THE UPPER LEVEL RIDGE AXIS. TC 03B IS EXPECTED TO
CONTINUE TRACKING NORTH-NORTHEASTWARD TO NORTHEASTWARD THROUGH 36
HOURS AND THEN EAST-NORTHEASTWARD ALONG THE NORTHWESTERN PERIPHERY
OF THE RIDGE. TC 03B IS EXPECTED TO SLOWLY WEAKEN THROUGHOUT THE
FORECAST PERIOD AS IT TRACKS ABOVE THE RIDGE AXIS INTO INCREASING
VERTICAL WIND SHEAR UNTIL DISSIPATION IS COMPLETE. LANDFALL EAST OF
CALCUTTA, INDIA, NEAR THE BORDER BETWEEN INDIA AND BANGLADESH, IS
FORECAST TO OCCUR BETWEEN 18 AND 24 HOURS TAU. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 120000Z3 IS 12 FEET. REFER TO WWIO30 RJTX FOR
