TROPICAL CYCLONE REWA, 26 DECEMBER 1993-21 JANUARY 1994 The first tropical phenomenon of the 93/94 season, REWA appeared in the intertropical convergence zone in the northeast part of Rotuma. The weak cyclonic circulation began to be well organized and drifted slowly westward. On the 28th at mid day, it was located 500 km to the northwest of Santa Cruz island. The clouds organization improveed, but the centre of the depression remained difficult to locate on satellite pictures. The depression continued its slow westward movement along the 10th south parallel. On the 29th early in the morning, its intensity was sufficient for Nadi Centre to name it REWA. It was then located between the Santa Cruz islands and San Cristobal island, which REWA crossed toward the west on the same day. Damages caused on this group of Solomon islands was very severe. Making its way west-southwest, REWA reached the tropical storm stage on the 30th and moved towards the southeast end of Papua- New Guinea. Hurricane strength was reached on the 31st when an eye appeared on satellite pictures. Under the influence of upper level steering flow, REWA curved toward the south and steadily deepened. It crossed the 20th south parallel on the 3rd of January with its maximum intensity, around 930 hPa. REWA was located midway between the Queensland coasts and Chesterfield group. The unexpected turn occurred in the night of the 3rd and 4th, when REWA changed its route again to move east-southeastward then east in a straight line toward New Caledonia. Its intensity began to weaken. On the 5th at mid day, it was located approximately 200 kn to the west of New Caledonia. The eye disappeared, and only surface data allowed us to determine the location of the centre. It seems that the terrain, although modest, of New Caledonia, was responsible for this change in intensity. Situated perpendicularly to the feeding flow of tropical air, the mountains affected REWA, which moves slowly, by a hot and dry Fhoen effect that disturbed the convection. REWA reacheed New Caledonia, on the 5th in the middle of the night, with storm force winds, in the vicinity of Saint Vincent bay on the west coast and came out near Thio on the east coast the next morning, completely disorganized. During the 6th REWA tracked between Lifou and Mare islands. The sea surface temperature of 26C and upper level configuration were unfavourable and did not allow REWA to regenerate. Moving toward the north-east towards Vanuatu, REWA was apparent only by its low level circulation and nearly disappeared on the 8th from satellite pictures. Only an eddy was visible, drifting northwestward, in the trade wind flow generated by a powerful high between New Zealand and Kermadec island. This path towards the Solomon's will last five days. The remains of REWA, found again, in the middle of the night of the 13th, favourable conditions for regeneration. This regeneration was rapid as it evolved from a weak tropical low stage to a tropical storm stage within 6 hours. REWA then moveed southeastward and deepened. On 15th hurricane stage is reached again and the maximum intensity of the second stage took place during the night of the 16th to the 17th with a sea level pressure of 920 hPa. Located on the morning of the 17th 100 km to the northeast of Chesterfield island, on a path that threatened directly New Caledonia, REWA radically changed its trajectory, as it neared the Chesterfield island, towards the Queensland's coast. At approximately 300 km off the Australian coasts on the 18th, at the latitude of Mackay, REWA made a loop to the north and followed the Queensland's shores. It then weakened slowly and became a tropical storm as it passed close to Fraser island the night of the 20th to the 21st. Steadily weakening, the low disappeared early on the 22nd, 500 km southeast of Brisbane. This tropical cyclone, is remarkable by its duration of life, practically a month. Its track made it sweep the entire Coral Sea. THE CYCLONE AFTERMATH IN NEW CALEDONIA The heavy rainfalls recorded in the southern part of the Territory during January 6th caused heavy flooding of all streams and rivers, in particular in the Mont Dore village vicinity where these floods caused the death of a 22 year old male. Several roads were closed to traffic because of the same problem. During the course of the 6th, many landslides were recorded. In Mare island, the wharf of Tadine harbour, which was under construction, was partly destroyed because of the swell.
