in Tonga

Global Telecommunication Service

GTS (Global Telecommunication Service) is the official Warning and Alerting channel by the World Meteorological Organization (WMO) adopted by several Warning Organizations. As soon as a new GTS message regarding Tropical Cyclones(WT) or Tsunami(WE) the messages are processed and possibly assigned to the specific event. When a new GTS message is present an new tab in the specific event report page is present.The presence of a GTS message is shown in the homepage with a dedicated icon.

REMARKS:
100300Z POSITION NEAR 23.7S 174.0W.
TROPICAL CYCLONE (TC) 14P (NEIL), LOCATED APPROXIMATELY 333 NM
SOUTHWEST OF NIUE, HAS TRACKED SOUTHWARD AT 17 KNOTS OVER THE PAST
SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A WELL-
DEFINED, FULLY-EXPOSED LOW-LEVEL CIRCULATION CENTER WITH DEEP
CONVECTION SHEARED TO THE EAST DUE TO STRONG WESTERLY VERTICAL WIND
SHEAR. OVERALL, THERE IS GOOD CONFIDENCE IN THE INITIAL POSITION. A
092035Z ASCAT-C BULLSEYE SHOWS A SYMMETRIC CIRCULATION WITH
EXTENSIVE 30 TO 35 KNOT WINDS OVER THE EASTERN SEMICIRCLE AND 15 TO
25 KNOT WINDS OVER THE WESTERN SEMICIRCLE. BASED ON THE ASCAT IMAGE,
THE RADIUS OF MAXIMUM WINDS IS ABOUT 40NM, WHICH REFLECTS THE
COMPACT, COHESIVE NATURE OF THIS WEAK TROPICAL CYCLONE. THE INITIAL
INTENSITY REMAINS ASSESSED AT 35 KNOTS BASED ON THE ASCAT DATA. TC
14P IS FORECAST TO TRACK SOUTH-SOUTHEASTWARD THROUGH THE FORECAST
PERIOD UNDER THE STEERING INFLUENCE OF A LOW- TO MID-LEVEL
SUBTROPICAL RIDGE POSITIONED TO THE EAST. THE SYSTEM IS FORECAST TO
REMAIN A WEAK TC AS IT TRACKS INTO THE SUBTROPICAL WESTERLIES AND
OVER COOL SST (LESS THAN 25C). TC 14P SHOULD DISSIPATE BY TAU 24 BUT
COULD DISSIPATE MORE RAPIDLY DUE TO THE MARGINAL ENVIRONMENTAL
CONDITIONS. NUMERICAL MODEL GUIDANCE IS IN TIGHT AGREEMENT,
THEREFORE THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST TRACK.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 100000Z IS 10 FEET. NEXT WARNINGS
AT 100900Z, 101500Z AND 102100Z.//

REMARKS:
092100Z POSITION NEAR 21.8S 174.6W.
TROPICAL CYCLONE (TC) 14P (NEIL), LOCATED APPROXIMATELY 302 NM WEST-
SOUTHWEST OF NIUE, HAS TRACKED SOUTH-SOUTHEASTWARD AT 17 KNOTS OVER
THE PAST SIX HOURS. TC 14P HAS TRANSITIONED INTO A WEAK WARM-CORE
TROPICAL CYCLONE. A 090849Z ASCAT IMAGE INDICATES AN ELONGATED BUT
DEFINED CIRCULATION WITH 30 TO 35 KNOT WINDS OVER THE EASTERN
SEMICIRCLE AND A RADIUS OF MAXIMUM WINDS NEAR 35NM, WHICH IS MORE
TYPICAL OF A TC. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A
DEFINED, FULLY-EXPOSED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH
PERSISTENT DEEP CONVECTION SHEARED 80 TO 90NM EAST DUE TO STRONG
WESTERLY VERTICAL WIND SHEAR. A 091726Z GMI 36GHZ MICROWAVE IMAGE
INDICATES IMPROVED YET SOMEWHAT FRAGMENTED SHALLOW BANDING OVER THE
WESTERN SEMICIRCLE WRAPPING INTO THE LLCC. OVERALL, THERE IS GOOD
CONFIDENCE IN THE INITIAL POSITION. THE INITIAL INTENSITY IS
ASSESSED AT 35 KNOTS BASED ON THE ASCAT DATA AS WELL AS DVORAK
CURRENT INTENSITY ESTIMATES OF 2.5 (35 KNOTS) FROM PGTW AND NFFN. TC
14P IS FORECAST TO TRACK SOUTH-SOUTHEASTWARD THROUGH THE FORECAST
PERIOD UNDER THE STEERING INFLUENCE OF A LOW- TO MID-LEVEL
SUBTROPICAL RIDGE POSITIONED TO THE EAST. THE SYSTEM IS FORECAST TO
REMAIN A WEAK TC AS IT TRACKS INTO THE SUBTROPICAL WESTERLIES AND
OVER COOL SST (LESS THAN 25C). TC 14P SHOULD DISSIPATE BY TAU 36 BUT
COULD DISSIPATE MORE RAPIDLY DUE TO THE MARGINAL ENVIRONMENTAL
CONDITIONS. NUMERICAL MODEL GUIDANCE IS IN TIGHT AGREEMENT,
THEREFORE THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST TRACK.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 091800Z IS 10 FEET. NEXT WARNINGS
AT 100300Z, 100900Z, 101500Z AND 102100Z.
