Australia’s Easter weather and potential severe tropical cyclone in Coral Sea
Consensus Summary
Australia is set for a mostly calm Easter weather pattern with settled conditions across most of the country, thanks to a high-pressure system moving east from Western Australia. However, meteorologists are monitoring a developing tropical cyclone in the Coral Sea, labeled 37U, which is expected to form around mid-next week and could threaten the Queensland coast. Both sources agree that the cyclone has a high chance of intensifying, with potential impacts ranging from Rockhampton to Cape York Peninsula, though the exact path remains uncertain. Capital cities like Sydney, Brisbane, Melbourne, and Hobart are forecast to experience a mix of showers and fine days, with Sydney and Brisbane seeing more rain early in the weekend. Canberra is expected to stay mostly dry, while Darwin faces isolated storms and high temperatures in the 30s. The Guardian emphasizes a blend of fine days and showers without any city being completely dry, while ABC provides more detailed state-by-state forecasts, including specific temperature ranges and rainfall probabilities. Both sources highlight the need for caution due to lingering flood risks in Queensland’s northeast and the potential for severe weather later in the week.
✓ Verified by 2+ sources
Key details reported by multiple sources:
- A high-pressure system is currently centered south of Western Australia and will move east toward the Tasman Sea, bringing settled weather to most of the country over Easter.
- Another Severe Tropical Cyclone (named 37U) is expected to develop in the Coral Sea around mid-next week, with a potential track toward the Queensland coast.
- The Bureau of Meteorology predicts system 37U will deepen and strengthen over the weekend, with a high chance of becoming a cyclone by Sunday when it is over the northern Coral Sea.
- Sydney is forecast to experience showers from Good Friday through Easter Sunday, with a break on Easter Monday, and maximum temperatures in the low-to-mid 20s.
- Brisbane will see temperatures in the high 20s and a chance of rain for the first three days of Easter, with windy conditions along the Queensland coast.
- Melbourne and Hobart are expected to have mostly fine weather from Friday to Sunday, with showers arriving on Easter Monday.
- Canberra is forecast to be mostly dry with maximum temperatures ranging between 19°C and 25°C over the long weekend.
- Darwin will experience isolated showers, storms, and temperatures in the 30s (°C) over Easter.
- The 11th tropical cyclone of the wet season is likely to form in the Coral Sea, with modeling suggesting a possible strike on the Queensland coast between Rockhampton and Cape York Peninsula.
Points of Difference
Details reported by only one source:
- Australia experienced its third-wettest February-March on record, with the country going through an entire week without major weather events (heatwaves, floods, cyclones) before Easter.
- The hottest Easter temperatures will be in the Pilbara and Kimberley regions, reaching around 40°C, while the coldest will be in the Tasmanian Highlands, dipping to freezing.
- Far North Queensland and Arnhem Land could see up to 50mm of rain, while the vast majority of Australia will receive less than 1mm of rain through the next four days.
- A trough of low pressure has the potential to bring showers to nearly all of Tasmania, Victoria, and adjacent parts of South Australia by Easter Monday.
- Perth’s chance of precipitation peaks at 30% on Saturday and Sunday, with maximums dropping from 28°C on Friday to 23-25°C between Saturday and Monday.
- The European Centre for Medium-Range Weather Forecasting (ECMWF) map shows a possible strike anywhere from Rockhampton to Cape York Peninsula, with a second landfall over the eastern Top End not ruled out.
- The system 37U could follow a similar track to Cyclone Narelle, and the gap between two direct cyclone strikes on Queensland’s coast would be the shortest since Cyclone Anthony and Yasi in early 2011.
- The ensemble prediction for 37U shows a range of scenarios from a Queensland coast strike to a route into the South Pacific, with the future path being far more uncertain than Cyclone Narelle’s.
- Senior meteorologist Jonathan How stated, ‘No capital city is forecast to be completely dry. At the same time, no city should be a washout,’ emphasizing a blend of fine days and showers.
- Adelaide is forecast to be ‘fairly warm’ with temperatures potentially hitting 29°C on Sunday, and a warning that chocolate left in the sun would melt.
- The system 37U is located between Papua New Guinea and Solomon Islands and naming rights for the cyclone would depend on where it forms, potentially being named Owen if it enters Australian waters.
- Marine wind warnings are expected along parts of the Queensland coast throughout the Easter weekend due to windy conditions.
- Thunderstorms are expected to roll through inland Western Australia on Good Friday, with the possibility of some reaching Perth, and temperatures in the mid-to-high 20s over the four days.
Contradictions
Conflicting information between sources:
- ABC states the hottest Easter temperatures will reach around 40°C in the Pilbara and Kimberley, while The Guardian does not mention specific temperature extremes beyond general forecasts.
- ABC mentions a 50-60% chance of precipitation in Brisbane from Friday to Sunday with a four-day total likely below 10mm, while The Guardian states Brisbane will have a chance of rain for the first three days without specifying totals.
- ABC reports that Perth’s maximums will drop from 28°C on Friday to 23-25°C between Saturday and Monday, while The Guardian only mentions temperatures in the mid-to-high 20s without specifying the exact drop.
- ABC highlights that the system 37U could follow a similar track to Cyclone Narelle and mentions a second landfall over the eastern Top End, while The Guardian does not mention these specific details about the track or potential second landfall.
- ABC provides a detailed state-by-state breakdown of weather conditions, including specific rainfall probabilities and temperature ranges, while The Guardian focuses more on general forecasts and warnings without the same level of granularity.
