AFAP manages the Australian-Pacific Centre for Emergency and Disaster Information (APCEDI) to provide news on natural disaster events in the Asia-Pacific region and to help with rapid disaster response assessment. This was originally a communications network that was activated during a disaster to disseminate information to our Asia-Pacific NGO offices. Now APCEDI has a much wider application across the Asia-Pacific Region.

APCEDI ALERT 10F #12, 2005: CYCLONE PERCY CONTINUES TO BATTER PUKAPUKA AND NASSAU ISLANDS IN NORTHERN COOKS; SOUTHERN COOKS PUT ON ALERT

Powerful Category 3/4 Cyclone Percy is making a near direct hit on the two westernmost of the Northern Cook Islands, Pukapuka (population 600) and Nassau (population 70). APCEDI has again contacted Chief Inspector John Tini in the Cooks Emergency Center based in Rarotonga. He reported that they have lost contact with Pukapuka since 8:00 AM local time. All 600 residents on Pukapuka have been evacuated to the Pukapuka School. As of 8:00 AM local time in Cooks, winds on Pukapuka were sustained at 55 kt with gusts up to 75 kt. Already 3 houses in Pukapuka have sustained serious damage.

In Nassau all 70 residents have also been evacuated to the 2 main churches (Catholic and Cooks Islands Christian) which are serving as Cyclone Shelters. Chief Inspector Tini also reported that Ham Radio contact was established with Nassau at 1:20 PM local time, and that at that time winds had died down to 15 kts. It is unclear whether this was because of the passage of the eye feature. Very heavy rain and hurricane force winds had done much damage to roofs on Nassau's houses according to the report.

Given the near direct hit of the storm's centre on Pukapuka and Nassau, authorities should expect widespread moderate to severe property damage on both islands. If communications are not restored with Pukapuka within a reasonable time later today after the storm's passage, then an aircraft should be sent immediately to assess the situation.

Chief Inspector Tini notes that a Royal New Zealand Airforce Plane was due to land at Rarotonga at about 4:00 PM local time this afternoon, and this might be used to assess damage in the Northern Cooks.

Percy continues to move eastsoutheast at 10 kt. Percy is still forecast to make a southern turn sometime in the next 12 hours. The timing of the turn is now critical for the Rakahanga and Manihiki Island to the east of Pukapuka. Manihiki Island was the location of the 1997 tragedy with Cyclone Martin where 19 people died. Authorities on both Rakahanga and Manihiki should be on alert and immediately rush cyclone preparedness plans to completion if the storm continues east. To the southeast on the island of Suwarrow, the two caretakers, who were the only people on the island, have been evacuated to Rarotonga since Cyclone Meena, and so no people are currently on the island.

Cyclone Percy is about 25 miles southsoutheast of Pukapuka and about 30 miles southwest of Nassau. Percy is still a major Category 3/4 strength on the Saffir-Simpson Scale, and according to the to JTWC and NOAA will continue to maintain strength although the FMS is calling for some weakening.

Most forecasts and models continue to show a southerly turn imminently, which would take the storm toward the Southern Cooks as a Category 3/4 cyclone. The Fiji Meteorological Service has now raised a Tropical Cyclone Alert for the Southern Cooks. So authorities in the Southern Cooks should be ready to undertake preparedness activities at short notice as the storm's progress warrants. Authorities in Niue and American Samoa should likewise continue on alert should a more unexpected south or westerly change occur later in the day.

Yesterday, the cyclone passed to the northeast of Swain's Island (population 5-20). All efforts to contact Swain's continue to be unsuccessful, and APCEDI would urge the US Government to undertake a flyover immediately or contact the New Zealand Government to do this in their course of dealing with Tokelau and Northern Cooks. Swains has been out of contact for over a week, and it is quite likely that the people there may need assistance as regular food drops have not been able to occur for several weeks.

The day before, Percy caused widespread damage and 1 injury on Tokelau's 3 atolls Atafu (population 500-600), Nukunonu (population 400-450) and Fakaofo (population 500), yesterday.

Authorities in American Samoa continue to maintain advisories and watches, and should be very vigilant in case Percy takes an unexpected early turn toward the south or west. Authorities on the Manu'a Islands of American Samoa should be particularly vigilant due to the high level of damage and debris from Cyclone Olaf last week.

Authorities in Tuvalu, Tokelau, Samoa, American Samoa, Wallis and Futuna, Cook Islands, Niue, Tonga and French Polynesia should continue to monitor this storm carefully. Due to damage of Cyclones Olaf, Nancy and Meena in this part of the Pacific, some island areas previously impacted will be more vulnerable. Disasters planners should make sure to take such increased vulnerability into account should it become necessary to implement preparedness activities.
