APCEDI Alert SP/SM Tropical Depression 06F #1-2006: New Tropical Depression 06F Forms as Cyclone Tam Exits into the Southern Ocean

RSMC-Tropical Cyclone Centre and the Joint Typhoon Warning Centre are issuing guidance on newly formed Tropical Depression 06F and on Cyclone Tam (formally Tropical Depression 04F). Just as Cyclone Tam exists into the Southern Ocean south of Niue, a new Tropical Depression, designated 06F, formed last night between Samoa and Northern Tonga.

As Cyclone Tam has passed well into the Southern Ocean and is no longer posing a threat to any island areas and has weakened, APCEDI will discontinue reporting on this system.

Tropical Depression 06F formed last night very quickly and is now located in Northern Tonga about 80 km southeast of Niuatoputapu or about 300 km north of the Vava'u Group. Tropical Depression 06F is moving southeast at 10 kt (18.5 km/hr) toward Niue where a Cyclone Alert has been raised.

The Tongan Niuas Group islands of Tafahi (population 60) and Niuatoputapu (population 1400) have spent the last few hours in the centre of the storm. Tropical Depression 06F should pass over 200 km northeast of the Vava'u Group so they are likely to only get a glancing blow. As 06F is a depression and moving quite quickly, damage is not likely to be too significant. Nonetheless, some tidal flooding and wind damage is likely, and all residents in the Niuas, Vava'u and Niue should continue to closely monitor the storm and all newscasts and follow all instructions issued by local authorities. Also, the cumulative effects of this very active trough which has included Cyclone Tam with Depressions 05F and 06F in the last 3 days, could begin to result in increasing crop damage, significant coastal erosion, and localised flooding of low-lying areas.

All interests in Tonga, Niue, the Cook Islands and French Polynesia should continue to monitor this situation carefully and listen to news and weather reports as the situations develops over the next few days. Even though the storms are moving away from other island areas such Wallis and Futuna, Fiji, Tuvalu, Tokelau, Samoa, and American Samoa, seas will remain very rough throughout much of the area and the associated trough is still causing locally strong winds, and heavy rains and thunderstorms. Where advisories, alerts and warnings have been raised all people should take appropriate action as instructed by local authorities. Pacific NGOs should monitor this situation very carefully.

With the very active Convergence Zone and all the tropical storm activity, there are a wide array of advisories, alerts and warnings that have been raised. The following is a list of advisories, alerts and warnings currently in effect.

FROM RSMC-TROPICAL CYCLONE CENTRE
Tropical Disturbance Advisory Number B1 issued from RSMC NADI Jan 13/2047 UTC 2006 UTC.

Tropical Depression 06F centre [999hPa] centre was located near 14.0S 174.0W at 131800 UTC. Position poor based on HR MTSAT EIR/VIS imagery with animation and peripheral surface reports. Depression moving southeast 10 knots. Maximum 10-minute average winds 20 to 25 knots increasing to 35 knots within 60 miles of centre in the next 12 to 24 hours.

06F erupted overnight with rapid development. Organisation now good and increasing. Deep convection cooling steadily. Primary band to east wrapping tightly around llcc. Some indication though of environmental influence. Outflow good to east and north but developing elsewhere. Depression lies under divergent 250-hpa flow and 20 to 25-kt shear. SST around 29C. Global models that have captured the system move it rather rapidly southeast with some intensification. Potential for 06F to become a cyclone in the next 24 hours is moderate to good.

The next Tropical Disturbance Advisory on Tropical Depression 06F will be issued around 140230 UTC.
