REMARKS:
140900Z POSITION NEAR 20.4S 77.1E.
14FEB21. TROPICAL CYCLONE 19S (FARAJI), LOCATED APPROXIMATELY 1005
NM EAST OF PORT LOUIS, MAURITIUS, HAS TRACKED WEST-SOUTHWESTWARD AT
08 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY (MSI) DEPICTS A FULLY EXPOSED LOW LEVEL CIRCULATION CENTER
WITH ISOLATED WEAK CONVECTION DISPLACED WELL TO THE SOUTHEAST DUE TO
THE STRONG NORTHWESTERLY FLOW ALOFT. THE INITIAL POSITION IS PLACED
WITH HIGH CONFIDENCE BASED ON THE EXPOSED CIRCULATION IN ANIMATED
VISIBLE IMAGERY. THE INITIAL INTENSITY IS LOWERED TO 30 KNOTS WITH
HIGH CONFIDENCE BASED ON A 140233Z METOP-A SCATTEROMETER PASS WHICH
INDICATED AN ISOLATED PATCH OF 30 KNOT WINDS IN THE SOUTHEAST
QUADRANT AND LESS THAN 20 KNOTS IN THE OTHER THREE QUADRANTS. HAVING
DISSIPATED BELOW WARNING CRITERIA DUE TO THE COMBINED EFFECTS OF DRY
AIR ENTRAINMENT, NORTHWESTERLY CONVERGENT FLOW ALOFT, AND PERSISTENT
MODERATE (15-20 KTS) VWS, THE REMNANTS OF TC 19S WILL CONTINUE
TRACKING GENERALLY WESTWARD ALONG THE NORTHERN PERIPHERY OF THE LOW
TO MID-LEVEL STR LOCATED TO THE SOUTH BUT ARE NOT EXPECTED TO
REDEVELOP. 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
140600Z IS 16 FEET.//

2.B LONGER-RANGE OUTLOOK:
NIL


2.C ADDITIONAL INFORMATION:
T=CI=2.5+

OVER THE PAST SIX HOURS, FARAJI'S SHEARED PATTERN HAS BECOME MORE
OBVIOUS, WITH THE MAXIMUM OF CONVECTION BECOMING INCREASINGLY
DETACHED TO THE SOUTH/SOUTHEAST OF A SURFACE CENTER WHICH IS MOVING
AWAY FROM THE CONVECTIVE AREA. THIS TILT BETWEEN THE LOW LEVEL CENTER
AND THE MID-TROPOSPHERE CONVECTIVE CORE IS VISIBLE ON CLASSICAL
SATELLITE IMAGERY AND ALSO CONFIRMED BY THE MICROWAVE IMAGES AMSR2 OF
0822Z AND SSM/I OF 1029Z. THE SATCON ANALYSIS IS ALSO WEAKER COMPARED
TO THIS MORNING. WITH A DT DECREASING TO 2.5+, ALL THESE ELEMENTS
CONFIRM AN INTENSITY REDUCED TO 35 KT AT 1200Z.

WITH THE WEAKENING OF THE SYSTEM, THE STEERING FLOW HAS MOVED DOWN TO
THE LOW TROPOSPHERE AND THE SUBTROPICAL RIDGE TO THE SOUTH INDUCES A
WESTWARD TRACK FOR THE NEXT FEW DAYS.

EVEN IF THE NORTHWESTERLY WIND SHEAR REMAINS MODERATE, THE INTRUSION
OF DRY AIR IN THE MID-TROPOSPHERE IS IMPORTANT ENOUGH TO WEAKEN
FARAJI. ACCORDING TO MOST MODELS, ENVIRONMENTAL CONDITIONS WILL
REMAIN UNFAVORABLE UNTIL THE MIDDLE OF NEXT WEEK (DRY AIR IN THE
MID-TROPOSPHERE, LACK OF LOW LEVEL INFLOW ON THE EQUATORIAL SIDE,
INSUFFICIENT CONVERGENCE ON THE POLAR SIDE), WHICH SHOULD LEAD FARAJI
TO A VERY WEAK STATE BY NEXT TUESDAY.

DUE TO ITS LOW INTENSITY, THIS SYSTEM DOES NOT PRESENT A CYCLONIC
RISK FOR THE INHABITED LANDS DURING THE NEXT 5 DAYS. HOWEVER, AS ITS
TRACK BRINGS IT CLOSER TO THE MASCARENES, A DEGRADATION OF WEATHER
CONDITIONS IS POSSIBLE.

THIS IS THE LAST BULLETIN ABOUT FARAJI.=
