TROPICAL DISTURBANCE ADVISORY NUMBER A5 ISSUED FROM RSMC NADI
Jan 282317 UTC.
TROPICAL CYCLONE FEHI CENTRE 991HPA WAS LOCATED NEAR 19.0S 161.5E AT
282100 UTC. POSITION FAIR BASED ON HR HIMAWARI 8 EIR AND VIS IMAGERY
AND PERIPHERAL SURFACE REPORTS. TROPICAL CYCLONE FEHI MOVING SOUTH
SOUTHEAST AT ABOUT 10 KNOTS. MAXIMUM 10-MINUTE AVERAGE WINDS NEAR THE
CENTRE ESTIMATED AT ABOUT 35 KNOTS.
DEEP CONVECTION AND OVERALL ORGANISATION HAS INCREASED IN THE PAST 3
HOURS. CYCLONIC CIRCULATION EXTENDS UP TO 500HPA. SST AROUND 29
DEGREES CELSIUS. OUTFLOW GOOD. SYSTEM LIES TO THE SOUTH OF AN UPPER
RIDGE AND EAST OF AN UPPER TROUGH IN A MODERATE SHEARED ENVIRONMENT.
SYSTEM IS BEING STEERED TO THE SOUTH-SOUTHEAST BY THE NORTH-NORTHWEST
DEEP LAYER MEAN WIND.
DVORAK ANALYSIS BASED ON 0.6 WRAP ON LOG 10 SPIRAL GIVING DT=3.0, MET
AND PT AGREE. FT BASED ON DT, THUS YIELDING 3.0/3.0/D0.5/24HRS
GLOBAL MODELS HAVE PICKED UP THE SYSTEM AND MOVE IT SOUTHEAST WITH
SLIGHT INTENSIFICATION.

TROPICAL DISTURBANCE ADVISORY NUMBER A1 ISSUED FROM RSMC NADI
Jan 280148 UTC.
TROPICAL DEPRESSION 06F CENTRE 994HPA WAS LOCATED NEAR 16.4S 160.2E
AT 280000 UTC. POSITION FAIR BASED ON HR HIMAWARI 8 EIR AND VIS
IMAGERY AND PERIPHERAL SURFACE REPORTS. TD06F MOVING SOUTH-SOUTHEAST
AT ABOUT 14 KNOTS. MAXIMUM 10-MINUTE AVERAGE WINDS NEAR THE CENTRE
ESTIMATED AT ABOUT 30 KNOTS.
DEEP CONVECTION REMAINS PERSISTENT. LLCC PARTIALLY EXPOSED WITH MOST
OF THE DEEP CONVECTION TO THE EAST AND SOUTH OF LLCC. ORGANISATION
HAS IMPROVED IN THE PAST 24 HOURS. CYCLONIC CIRCULATION EXTENDS UP TO
500HPA. SST AROUND 30 DEGREES CELSIUS. OUTFLOW GOOD. SYSTEM LIES TO
THE SOUTH OF AN UPPER RIDGE AND EAST OF AN UPPER TROUGH IN A MODERATE
SHEARED ENVIRONMENT. SYSTEM IS BEING STEERED TO THE SOUTH-SOUTHEAST
BY THE NORTH-NORTHWEST DEEP LAYER MEAN WIND. DVORAK ANALYSIS BASED ON
0.4 WRAP YIELDS DT=2.5. PT AND MT AGREE. FT BASED ON DT. THUS
YIELDING T2.5/2.5/D1.0/24HRS.
POTENTIAL FOR THIS SYSTEM TO DEVELOP INTO A TROPICAL CYCLONE WITHIN
THE NEXT 24 HOURS IS HIGH.
