REMARKS:
201500Z POSITION NEAR 22.7N 88.4E.
20MAY20. TROPICAL CYCLONE (TC) 01B (AMPHAN), LOCATED APPROXIMATELY 25
NM SOUTH-SOUTHWEST OF KOLKATA, INDIA, HAS TRACKED NORTHWARD AT 17
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY (MSI) AND ENHANCED INFRARED IMAGERY DEPICTS A SYSTEM WITH 
UNIFORM CENTRAL DENSE OVERCAST (CDO) THAT CONTINUES TO ERODE. TC 01B 
HAS NOW PASSED OVER LAND. THE INITIAL POSITION IS PLACED WITH GOOD 
CONFIDENCE BASED ON A 201120Z AMSU 89GHZ MICROWAVE IMAGE PASS WHICH 
SHOWS THAT THE STRONGEST REMAINING CONVECTION IS NOW LIMITED TO THE 
NORTHERN QUADRANT AND CONTINUES TO WEAKEN. RADAR DATA FROM INDIA 
SUPPORTS THE ASSESSMENT OF THE MICROWAVE DATA AND THE INITIAL 
POSITION. THE INITIAL INTENSITY IS ASSESSED WITH FAIR CONFIDENCE AT 75 
KNOTS BASED ON A PGTW CURRENT INTENSITY ESTIMATE OF T5.5 (102 KNOTS), 
AN ADVANCED DVORAK TECHNIQUE ESTIMATE OF T4.2 (61 KNOTS) JUST BEFORE 
LANDFALL. ADDITIONALLY, CALCUTTA OBSERVED A PRESSURE DROP MEASURED AT 
985MB WITHIN 4NM OF THE STORM PATH AT 201200Z. THE OVERALL ENVIRONMENT 
IS POOR WITH MODERATE TO STRONG (20 TO 25 KNOTS) VERTICAL WIND SHEAR 
(VWS) DESPITE GOOD POLEWARD OUTFLOW. THE SYSTEM CONTINUES TO TRACK 
NORTH-NORTHEASTWARD ALONG THE WESTERN PERIPHERY OF A DEEP-LAYER NER 
CENTERED TO THE EAST. THIS TRACK MOTION IS EXPECTED TO MAINTAIN 
THROUGH THE REMAINDER OF THE FORECAST PERIOD. SUSTAINED STRONG (25 
KNOTS) VWS SHEAR AND LAND INTERACTION WILL RAPIDLY WEAKEN TC 01B 
BEFORE IT DISSIPATES BY TAU 24. DYNAMIC GUIDANCE IS IN GOOD AGREEMENT 
THROUGHOUT THE FORECAST PERIOD, LENDING HIGH CONFIDENCE TO THE JTWC 
FORECAST TRACK. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT 
TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM WILL BE CLOSELY MONITORED 
FOR SIGNS OF REGENERATION.//
