Tropical Cyclone Joy· Cyclone technical report no. 2 •December 1990 •ISSN 1327-2837 Introduction From the data obtained, a peak storm surge of 0.45 metres was recorded at Port Douglas at OOOOh (AEST) 24 On 19 December 1990, tropical cyclone Joy formed out of a December 1990. High waters at Port Douglas were tropical depression in the north Coral Sea approximately predicted for 0232h and 1428h on 940km east-north-east of Cooktown. Over the next three 24 December 1990. The passage of tropical cyclone Joy days Joy moved on a generally west-south-westerly track coincided with neap tides throughout the region and the and slowly intensified to Category 3 (on a scale of 1 to 5) at resulting storm tide levels were therefore below predicted 1600h (AEST) on 21 December 1990. At this time the highest astronomical tide (HAT). Note that the HAT values system was 420km north-east of Cooktown and had an used in this report are taken from the 1990 Official Tide estimated central pressure of 970HPa.

The Trinity Ayr. At landfall, Joy had a central pressure of approximately wave recording station (trialling the Authority's upgraded 985HPa with estimated wind gusts to 110km/h. The system wave recording system) was configured to record data at further degenerated into a tropical depression later in the intervals of one hour and the software enabled real time evening of 26 December 1990, south-west of Ayr. access to the recorded data via the Public Switched Telephone Network. This facility was used during tropical Tropical cyclone Joy posed one of the most extreme threats cyclone Joy to monitor the incidence of heavy wave to Queensland coastal populations in recent times.

Figures 4 to 16 present measured water levels, predicted tides and the residual levels for each site. It should be noted that the measured water level data are represented Coastal Observation Program - as hourly values which have been determined from the ten Engineering minute records. Volunteer observers involved with the Beach Protection Authority's Coastal Observation Program - Engineering The storm surge tide recording system also allows (COPE) were asked to carry out beach profile interrogation via the Public Switched Telephone Network for measurements directly following the passage of the real time access during cyclone events. This facility was cyclone, where possible. These profiles were then plotted used during the passage of tropical cyclone Joy to monitor and compared with previous data to assess the extent of any storm surge. Several storm tide warnings were issued beach change. Additional information obtained from the for Joy advising of potential coastal inundation hazards due COPE observers in the aftermath of tropical cyclone Joy to an estimated storm surge of up to two metres between relating to beach conditions proved invaluable to Authority Port Douglas and Cardwell. officers in the assessment of local conditions.

Cardwell and Hinchinbrook Shires A small number of cases of beach erosion were reported including some minor slumping of a rock wall at Tully Heads and some re-shaping of a re-nourished beach at Cardwell. See photographs in Figure 44.
Thuringowa City At Toolakea Beach, in the vicinity of a creek mouth re-alignment project undertaken in 1989, the effects of the cyclone were mainly beneficial with sand from offshore banks being fed onshore. Some slight erosion was reported at Saunders Beach and Cungulla.
Townsville City Due to the passage of tropical cyclone Joy, a slight acceleration of the continuing erosion and coastline recession was observed in the Rowes Bay area. No other problems were reported.
Bowen and Whitsunday Shires No inspections of sites in these Shires were undertaken. However, reports were received of wave damage to marina pontoons at Daydream Island.
Pioneer Shire Substantial beach erosion was reported in this region; some is shown in Figures 45 and 46. Moderate erosion and tree losses were reported at Midge Point, Halliday Bay, Seaforth, St Helens Beach and Ball Bay. Due to coastline recession, the erosion scarp at Ball Bay was reported to be approximately two metres from the road in one location. At Shoal Point, erosion scarps of three metres and extensive destruction of fencing and walkways were reported. Lesser erosion occurred at Eimeo and scarps of two to three metres were observed at Bucasia and Lamberts Beach.
Mackay City Along the dune system of Town Beach a number of breakthroughs were reported and damage occurred to the rock wall fronting the park. At Far Beach the storm wave conditions overtopped and damaged the rock wall. See photographs in Figure 47.
Sarina Shire Some moderate erosion was reported in this region along with a number of problems associated with stormwater run-off at Louisa Creek, Grasstree, Salonika, Sarina and Armstrong Beaches. See photographs in Figure 47.
Broadsound Some coastline recession which threatened property boundaries was reported at Clairview.
