受到強風切的影響 發展方面受到了很大的阻礙 發展方面應該有一定困難 稍早JTWC也取消了 TCFA 並降評為Low THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 16.0S |

美國早就撤編 93P,但斐濟仍維持並認為這兩天發展機會達到中至高,GFS 也認為會發展。 MODERATE TO HIGH WWPS21 NFFN 220900 CCA Tropical Disturbance Summary For area Equator to 25S, 160E to 120W ISSUED FROM RSMC NADI Dec 22/0959 UTC 2014 UTC. TROPICAL DISTURBANCE 03F CENTER [1003HPA] ANALYSED NEAR 13.9S 162.7W AT 220600UTC. TD03F SLOW MOVING. POSITION POOOR BASED ON GOES IR IMAGERY AND PERIPHERAL OBSERVATIONS. SST AROUND 30 DEGRESS CELCIUS. ORGANISATION IS POOR. CONVECTION IS PERSISTANT IN THE PAST 12 HOURS. THE SYSTEM LIES UNDER AN UPPER DIFFULENT REGION IN A LOW SHEARED ENVIRONMENT AND EAST OF AN UPPER SHORTWAVE TROUGH. CYCLONIC CIRCULATION EXTENDS UPTO 500HPA. GLOBAL MODELS HAVE PICKED THE SYSTEM AND MOVE IT EAST AND THEN SOUTHEAST WITH LITTLE INTENSIFICATION. POTENTION FOR TD03F TO DEVELOP INTO A TROPICAL CYCLONE IN THE NEXT 24 TO 48 HOURS IS MODERATE TO HIGH. |
