Part of the1978–79 Australian region cyclone season | |
Severe Tropical Cyclone Peter was at the time, thewettesttropical cyclone on record inAustralia, until it was surpassed byCyclone Jasper in 2023. The third system and first severe tropical cyclone of the1978–79 season, Peter developed on 29 December from a weak low pressure area over theGulf of Carpentaria. Peter moved southeastward and deepened while brushingArnhem Land. Initially a tropical low, it strengthened into a Category 1 cyclone by 12:00 UTC on 29 December. Peter intensified further on 30 December and became a Category 2 cyclone. On the following day, the cyclone peaked with maximum sustained winds of 110 km/h (70 mph). Peter weakened to a Category 1 cyclone before making landfall near the mouth of theEdward River inQueensland. While crossing theCape York Peninsula, the storm weakened slowly. After reaching Pacific Ocean nearCooktown, the storm decelerated and meandered offshore, but dissipated just offshore on 4 January.
While trekking slowly offshore the east coast of Queensland, the storm dropped very heavy rainfall, peaking at 1,947 millimetres (76.7 in) atMount Bellenden Ker, making it the wettest tropical cyclone on record in Australia at the time. Severe flooding occurred, especially in theCairns area. The most severe damage was dealt tosugar cane, which suffered 70 to 90 percent destruction. Some flights were canceled at theCairns Airport due to standing water. Floodwaters forced at least 50 people to flee their homes in Cairns. A number of roads, including major highways, were flooded throughout coastal areas ofFar North Queensland. Rainfall and winds also resulted in many power and telephone service outages through the region. There were two fatalities and damage reached approximately $10 million (1979 AUD; $11.4 million 1979 USD).
Extratropical cyclone, remnant low, tropical disturbance, or monsoon depressionDuring the final week of December 1978, an area ofatmospheric convection developed over northern Australia and surrounding areas.[1] During 28 December, an area of low pressure developed over the easternArnhem Land within this area of atmospheric convection.[1] Over the next day the system moved northwestward toward theGulf of Carpentaria and developed further, with the first gale force wind associated with the system reported from an automatic weather station on 29 December.[1] The system was subsequently named Peter by the AustralianBureau of Meteorology(BoM) after it moved into the Gulf and developed into a Category 1 tropical cyclone on theAustralian tropical cyclone intensity scale.[2] After being named, Peter continued to intensify further as it tracked southeastward toward theCape York Peninsula.[2]
The system was subsequently considered to have peaked as a Category 2 tropical cyclone on 31 December, with 10-minute sustained winds estimated at 110 km/h (70 mph) by the BoM.[2] Several hours later, the system made landfall betweenAurukun and theEdward River mission,Queensland, at around 20:00 (Australian Eastern Standard Time, 11:00 UTC).[3] As Peter made landfall during 31 December winds of 120 km/h (75 mph), were reported from bothFitzroy Island and the Edward River mission weather stations.[1] Over the next couple of days the system gradually weakened over land, before it emerged into the Coral Sea nearCooktown, Queensland, on 1 January.[4] The system subsequently weakened below tropical cyclone intensity and became a tropical low during 2 January.[5] The system was last noted on the following day as it degenerated into a complex low pressure system and moved back over theCape York Peninsula.[4][6] The complex low subsequently moved westwards over the Peninsula and into the Gulf, where it developed intoTropical Cyclone Greta.[7]

TheDarwinTropical Cyclone Warning Centre (TCWC) inNorthern Territory issued acyclone warning on 30 December for the coast of Arnhem Land from theWessel Islands to Port Roper, located near the mouth of theRoper River.[18] Although a cyclone warning indicates expectation of landfall,[19] Peter would never strike Northern Territory.[1] The strongest observed winds in the territory was 74 km/h (46 mph) on Northeast Island, while the highest precipitation total was 140 millimetres (5.5 in) inNhulunbuy, 107 mm (4.2 in) of which fell in 24 hours. Very rough seas were reported along the coast of some areas, beaching a 12 m (39 ft) fishing vessel onto the rocks atGove harbour.[2]
In Queensland, theBrisbane TCWC issued cyclone watches and flood warnings as the storm passed over the Cape York Peninsula.[20] Some areas experienced strong winds, with gusts up to 110 km/h (68 mph) at Edward River Aboriginal Mission andFitzroy Island.[1] The storm dropped very heavy rainfall while drifting offshore Queensland, withMount Bellenden Ker recording 1,947 mm (76.7 in) over a period of approximately three days, making Peter thewettest tropical cyclone in Australia at the time.[21] The record precipitation total was surpassed byCyclone Jasper in December 2023, which dropped 2,252 mm (88.7 in) over a seven day period.[22] In a 24 hour period, Peter dropped about 1,140 mm (45 in) of rainfall, which was the country's highest daily rainfall total. Other significant precipitation amounts included 433 mm (17.0 in) inMillaa Millaa and 402 mm (15.8 in) in Cooktown.[1]
Due to the heavy rainfall, severe flooding occurred, mostly betweenTully and Cooktown, with the worst impact in theCairns area.[1] Many creeks and rivers, such as theHerbert, the north and south branches of theJohnstone, and McLeod rivers overflowed or reached dangerous levels. Much of the damage inNorth Queensland occurred to newly plantedsugar cane, with approximately 70 to 90 percent of area's crop destroyed. Twenty growers inGoondi each lost between $20,000 to $30,000 in sugar cane. Damage to this crop was comparable to the floods in 1977.[23] In total, the storm destroyed 270,000 to 315,000 tonnes of sugar cane.[24]
Standing water atCairns Airport ledAnsett Australia to cancel some flights. Portions of many roads, including major highways such as theBruce,Captain Cook, Gillies,[20] andKennedy highways were reported by theRoyal Automobile Club as closed due to inundation and washouts.[23] Many motorists were left stranded by floodwaters on Bruce Highway.[20] Emergency personnel crews were put on standby inInnisfail as water up to 60 cm (24 in) threatened dozens of homes in the eastern part of town.[20] In Cairns, over 50 people fled their homes.[25] On 5 January, theCoast Guard of Australia began evacuating some 160 stranded campers in areas about 140 km (85 mi) north ofMossman. Foods shortages occurred in some areas ofFar North Queensland, forcing several emergency food drops, including to about 250 people on 4 January and 70 people on 5 January. Additionally, a policeman was winched by helicopter to deliver food supplies to 10 isolated people on 7 January in Goldsborough, which is located in theGillies Range to the west ofGordonvale. Overall, Peter left two fatalities and about $10 million (1979 AUD) in damage, at least $4.5 million of which was done to sugar cane inBabinda, Innisfail, and Tully.[23]
After the storm, theGovernment of Queensland declared the Cairns area as a natural disaster area. About week later, theCabinet supported a measure by Minister for Primary Industries, Vic Sullivan, to offer low-interest loans to farmer who lost significant amounts of crops and livestock.[3] Later,Queensland PremierJoh Bjelke-Petersen requested aid from thenational government.Prime MinisterMalcolm Fraser approved low-interest loans up to $25,000 (1979 AUD) for small businesses and the implementation of other measures for recovery.[26]
