REMARKS:
242100Z POSITION NEAR 15.4N 54.8E.
TROPICAL CYCLONE (TC) 02A (MEKUNU), LOCATED APPROXIMATELY 125 NM 
SOUTH-SOUTHEAST OF SALALAH, OMAN, HAS TRACKED NORTH-NORTHWESTWARD AT 
09 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR) 
SATELLITE IMAGERY OVER THE PAST THREE HOURS DEPICTS A RAPIDLY 
INTENSIFYING SYSTEM, WITH A COMPACT 12 NM EYE FORMING BY THE 241700Z 
HOUR. THE EYE FEATURE PEAKED BY 241800Z IN A CONTINUATION OF THE 
INTENSIFICATION-WEAKENING CYCLE EVIDENT OVER THE PAST 48 HOURS. THE 
INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE 12 NM 
EYE FEATURE. THE INITIAL INTENSITY HAS BEEN INCREASED TO 80 KNOTS 
BASED ON A DVORAK CURRENT INTENSITY ESTIMATES RANGING FROM T4.0 (77 
KNOTS) TO T5.0 (90 KNOTS) FROM KNES AND PGTW RESPECTIVELY, AS WELL 
AS A SATCON ESTIMATE OF 81 KNOTS FROM 241433Z. AUTOMATED DVORAK 
ESTIMATES HAVE DROPPED TO ONLY 60 KNOTS, AND THESE ARE NOT 
REPRESENTATIVE OF THE ACTUAL INTENSITY. A 241801Z GPM 89GHZ IMAGE 
CONFIRMED THE INTENSIFICATION EVIDENT IN THE EIR IMAGERY, WITH A 
DISTINCT MICROWAVE EYE FEATURE AND A COMPACT AREA OF DEEP CONVECTION 
WRAPPING INTO THE LLCC, MOST IN A NARROW BAND ACROSS THE 
SOUTHWESTERN SEMICIRCLE. TC 02A CONTINUES TO TRACK NORTHWESTWARD 
ALONG THE WESTERN PERIPHERY OF A SUBTROPICAL RIDGE SITUATED TO THE 
NORTH AND EAST. NO SIGNIFICANT CHANGE IS EXPECTED IN THE FORECAST 
TRACK WITH NORTHWESTWARD MOTION FORECAST TO PERSIST  UNTIL TAU 36. 
THE SYSTEM IS FORECAST TO MAKE LANDFALL JUST PRIOR TO TAU 24 BETWEEN 
SALALAH, OMAN AND THE YEMEN-OMAN BORDER. ENVIRONMENTAL ANALYSIS 
INDICATE LOW VWS (10-15 KNOTS), WARM SSTS (30 DEG CELSIUS) AND 
STRONG, NEARLY RADIAL OUTFLOW, ALL OF WHICH SUPPORT SOME NEAR-TERM 
INTENSIFICATION, PEAKING AT 90 KNOTS PRIOR TO LANDFALL. TC 02A 
TRACKS INLAND AFTER TAU 24 AND WILL UNDERGO RAPID DISSIPATION WHILE 
GRADUALLY TURNING NORTHWESTWARD UNDER THE INFLUENCE OF A BUILDING 
RIDGE TO THE NORTH. NUMERICAL MODEL GUIDANCE REMAINS IN GOOD 
AGREEMENT, LENDING HIGH CONFIDENCE TO THE JTWC FORECAST TRACK.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 241800Z IS 26 FEET. NEXT
WARNINGS AT 250300Z, 250900Z, 251500Z AND 252100Z.//
