REMARKS:
192100Z POSITION NEAR 27.0S 73.4E.
19MAR20. TROPICAL CYCLONE (TC) 22S (HEROLD), LOCATED APPROXIMATELY 
948 NM EAST-SOUTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED
SOUTHEASTWARD AT 11 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED 
INFRARED (EIR) SATELLITE IMAGERY DEPICTS A WELL DEFINED, FULLY 
EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) WITH SPORADIC, FLARING 
CONVECTION SHEARED OVER THE SOUTHEASTERN SEMICIRCLE. THE INITIAL 
POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE LLCC IN THE EIR 
LOOP AND EXTRAPOLATION FROM A BROAD LLCC PRESENT IN A 191303Z SSMIS 
37 GHZ IMAGE. THE INITIAL INTENSITY OF 30 KTS IS ALSO PLACED WITH 
HIGH CONFIDENCE BASED ON A PGTW DVORAK CURRENT INTENSITY ESTIMATE OF 
T1.5 (25 KTS) AND THE PRESENCE OF 30 KTS WINDS LOCATED TO THE EAST-
NORTHEAST OF THE LOW LEVEL CIRCULATION IN TIMELY 191727Z METOP-B 
ASCAT DATA. TC 22S IS TRACKING ALONG THE SOUTHERN PERIPHERY OF A 
SUBTROPICAL RIDGE TO THE NORTH INTO AN INCREASINGLY UNFAVORABLE 
ENVIRONMENT WITH HIGH (30-35 KTS) VERTICAL WIND SHEAR (VWS) AND COOL 
(25-26 CELSIUS) SEA SURFACE TEMPERATURES (SST). THESE UNFAVORABLE 
CONDITIONS HAVE CAUSED TC HEROLD TO WEAKEN SIGNIFICANTLY AND 
DISSIPATE OVER WATER. NUMERICAL MODEL SOLUTIONS ARE IN GOOD 
AGREEMENT, LENDING HIGH CONFIDENCE IN 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. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 191800Z
IS 17 FEET.
