1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 99W) PREVIOUSLY LOCATED
NEAR 7.5N 166.5E, IS NOW LOCATED NEAR 8.5N 163.4E, APPROXIMATELY 202
NM EAST-SOUTHEAST OF UJELANG. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY, SUPPORTED BY 010051Z GMI 89/37 GHZ MICROWAVE IMAGES, SHOWS
A WEAK, ASYMMETRIC LOW LEVEL CIRCULATION CENTER (LLCC) WITH
FRAGMENTED DEEP CONVECTION OVERHEAD AND POTENTIAL FORMATIVE BANDING
EXTENDING SOUTH. A 311045Z METOP-B ASCAT PASS REVEALS A SWATH OF 15
TO 20 KNOT WINDS OFFSET TO THE NORTH OF AN OBLONG, ILL-DEFINED LLCC.
99W IS CURRENTLY IN A FAVORABLE ENVIRONMENT WITH EXCELLENT POLEWARD
OUTFLOW, LOW (5 TO 10 KNOT) VERTICAL WIND SHEAR, AND WARM (29 TO 30
CELSIUS) SEA SURFACE TEMPERATURE. GLOBAL MODELS ARE IN GOOD
AGREEMENT THAT 99W WILL CONTINUE TO TRACK NORTHWESTWARD WHILE
INTENSIFYING, REACHING WARNING THRESHOLD WITHIN THE NEXT COUPLE OF
DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.

Location: 16.8°N 59.5°E
Maximum Winds: 25 kt
Minimum Central Pressure: 1005 mb
REMARKS:
312100Z POSITION NEAR 16.9N 59.4E.
31OCT19. TROPICAL CYCLONE (TC) 04A (KYARR), LOCATED APPROXIMATELY 1026 NM EAST-NORTHEAST OF DJIBOUTI (CITY), HAS TRACKED SOUTH-
SOUTHWESTWARD AT 02 KNOTS OVER THE PAST SIX HOURS. A PARTIALLY EXPOSED, ILL-DEFINED LOW LEVEL CIRCULATION CENTER (LLCC) IS EVIDENT IN ENHANCED INFRARED SATELLITE IMAGERY. THE INITIAL INTENSITY OF 30 KNOTS IS CONSISTENT WITH A 311620Z METOP-A ASCAT PASS SHOWING A SMALL PATCH OF 25-30 KNOT BARBS EMBEDDED IN THE ONLY REMAINING CONVECTION 100NM SOUTHWEST OF THE LLCC. THE POSITION IS PLACED WITH OVERALL GOOD CONFIDENCE. THE ENVIRONMENT, WITH WEAK OUTFLOW, WARM (27-28 CELSIUS) SEA SURFACE TEMPERATURE (SST), AND LOW (5-10 KT) VERTICAL WIND SHEAR (VWS) IS MARGINALLY FAVORABLE. ADDITIONALLY, THERE IS DRY AIR ENTRAINING IN FROM THE WEST, WHICH IS GRADUALLY DISSIPATING TC 04A. FOR THE DURATION OF THE FORECAST, TC 04A WILL TRACK ALONG THE PERIPHERY OF A SUBTROPICAL RIDGE (STR) TO THE WEST. DYNAMIC MODEL GUIDANCE IS IN EXCELLENT AGREEMENT, LENDING HIGH CONFIDENCE TO THE JTWC TRACK FORECAST. 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 311800Z IS 14 FEET. REFER TO TROPICAL CYCLONE 05A (MAHA) WARNINGS (WTIO32 PGTW) FOR SIX-HOURLY UPDATES.//

TC MAHA(05A)
As of 00:00 UTC Nov 01, 2019:
Location: 15.1°N 71.8°E
Maximum Winds: 50 kt ( 95km/h)
Gusts: 65 kt ( 120km/h)
Minimum Central Pressure: 996 mb
REMARKS:
010300Z POSITION NEAR 15.4N 71.5E.
01NOV19. TROPICAL CYCLONE (TC) 05A (MAHA), LOCATED APPROXIMATELY 808
NM EAST-SOUTHEAST OF MASIRAH ISLAND, HAS TRACKED NORTHWESTWARD AT
10 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED IMAGERY
AND A 312041Z AMSR 89GHZ MICROWAVE IMAGE SHOW SHALLOW BANDING TO THE
EAST OF A CENTRAL DENSE OVERCAST. THERE IS OVERALL FAIR CONFIDENCE
IN THE INITIAL POSITION. THE INITIAL INTENSITY OF 50 KNOTS IS IN
GOOD AGREEMENT WITH A MULTI-AGENCY DVORAK ESTIMATE OF T3.0-3.5 (45-
55 KTS) AND A 312030Z SATCON ESTIMATE OF 50 KNOTS. ENVIRONMENTAL
ANALYSIS SHOWS A MODERATELY FAVORABLE ENVIRONMENT WITH LOW (05-10
KNOT) VERTICAL WIND SHEAR, FAIR POLEWARD OUTFLOW OFFSET TO THE
SOUTHWEST OF THE LLCC AND WARM (28-29 CELSIUS) SEA SURFACE
TEMPERATURE (SST). TC 05A IS TRACKING ALONG THE SOUTHWESTERN
PERIPHERY OF A SUBTROPICAL RIDGE (STR) POSITIONED OVER NORTHERN
INDIA. THE STR WILL MAINTAIN AS THE PRIMARY STEERING FEATURE OF TC
05A FOR THE REMAINDER OF THE FORECAST. UPPER LEVEL DIVERGENCE IS
EXPECTED TO BECOME SLIGHTLY MORE FAVORABLE AS TC 05A PROGRESSES
ALONG ITS TRACK POLEWARD. HOWEVER, BETWEEN TAU 48 AND 96, THE TRACK
SHOULD TAKE TC 05A OVER UPWELLED, COOLER WATERS (26-27 DEGREES
CELSIUS) FROM TC 04A LIMITING THE INTENSIFICATION RATE. DYNAMIC
MODEL GUIDANCE GENERALLY AGREES WITH THE JTWC TRACK FORECAST WITH A
SPREAD IS 200NM BY TAU 72. AFTER TAU 72, THERE IS SIGNIFICANT
UNCERTAINTY WHETHER TC 05A WILL RECURVE TOWARDS NORTHWESTERN INDIA
OR BEGIN TRACKING WESTWARD TOWARDS OMAN. THE JTWC TRACK IS CURRENTLY
HEDGING TOWARDS THE RECURVE SCENARIO WITH LOW CONFIDENCE. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 010000Z IS 18 FEET. NEXT WARNINGS AT
010900Z, 011500Z, 012100Z AND 020300Z.
