(WIND GUSTS AT SEA MAY BE ABOUT 40% STRONGER THAN THE AVERAGED WIND).

MINIMUM SEA LEVEL PRESSURE IN HECTOPASCALS (HPA)

(INDICATIVE FIGURE).



WARNING

BEGINNING OF VALIDITY: TUESDAY   27/12/2005 AT 1200 UTC.



PHENOMENON:        TROPICAL DISTURBANCE 6 1004 HPA

POSITION:          WITHIN 60 NM RADIUS OF POINT 15.0S / 68.0E

(FIFTEEN DECIMAL ZERO DEGREES  SOUTH AND SIXTY EIGHT DECIMAL ZERO

DEGREES

MOVEMENT:          WEST-SOUTH-WEST 12 KT



THREAT AREAS:

SQUALLY WEATHER  EXISTS WITHIN 90 NM RADIUS OF THE CENTER EXTENDING

UP TO

 200 NM IN THE SOUTHERN SEMI-CIRCLE.



CLOCKWISE CIRCULATION 20/25 KT AND MODERATE TO ROUGH SEAS WITHIN 30

NM

RADIUS OF THE CENTRE, LOCALLY REACHING NEAR GALE FORCE WINDS 30 KT IN

THE

 SOUTHERN SEMI-CIRCLE DUE TO THE GRADIENT EFFECT.

STRONG GUSTS UNDER SQUALLS.



FORECAST POSITION AND INTENSITY:

12H, VALID 2005/12/28 AT 00 UTC:

OTHER INFORMATIONS:

LOW LEVEL CIRCULATION CENTER IS BAD DEFINED AND HAS BEEN RELOCALISED

MORE

 NORTHERN.

DEEP CONVECTION REMAINS CYCLIC AND IS MAINLY LOCATED SOUTHWEST FROM

THE

LOW LEVEL CIRCULATION CENTER.

POTENTIAL FOR INTENSIFICATION REMAINS LIMITED.

THE SYSTEM IS EXPECTED TO TRACK WEST-SOUTHWESTWARDS WITHOUT

INTENSIFYING

SIGNIFICANTLY.
