Tropical Cyclone Zelia landed in Western Australia about 30 miles east of 11:30 PM EST on Thursday, February 13, at 12:30 PM local time on February 14 at 12:30 PM local time. At the time of landing, the Joint Typhoon Warning Center rated Zelia as Zelia, a 4-class storm with a 130 mph (209 km/h) wind for Zelia. Port Hedland recorded peak wind gusts of 75 mph, and Zelia dumped 17.16 inches (44 cm) of rain in 48 hours at Pardoo Station. Fortunately, the stormy eyes missed Harden Harbor (Pop. 15,000), and Zelia mainly affects sparsely populated areas. Zelia is the first major tropical cyclone on Earth to land in 2025.

Australia's Rare Cat 4 Login
Since 1961, Australia's mainland has been hit by 18 other storms on the Saffir-Simpson air meter. The strongest hurricane that hit the Australian continent (and most recently the major hurricane that hit the country) was the ILSA in April 2023, which hit a densely populated area about 50 miles east of Port Hedland, when it was Saffir- Simpson Scace's Cat 4, with 155 mph (250 km/h) wind, with a central pressure of 924 MB.
In the NOAA database, there are only three CATs on the Saffir-Simpson scale, within 50 miles of Australia. None of these reached the Australian continent of Class 5, but Monica hit the Marthinbar Island in Australia on April 23, 2006 with a 180 mph wind, the cat is located in the mainland. Near the northern coast.

Average tropical cyclone season in Australia so far
Zelia is the fifth storm in Australia during the 2024/2025 hurricane season, which is close to average. Zelia is Australia's first landing storm this season, and it's the late stage of its first landing. According to the Colorado State University’s live tropical cyclone activity page, the average of the entire tropical cyclone season throughout the Southern Hemisphere is close to average, depending on the metric used. So far, by 2024/2025, there have been 16 named storms, 7 hurricanes, 6 major hurricanes and a cumulative cyclone energy, or ACE, with an index of 141. The average 1991-2020 is 14 named storms, seven One hurricane, four major hurricanes, the ace index is 105.
Recording warm ocean temperatures helps Zelia exacerbate
Zelia quickly strengthened its approach to the Australian coast, peaking at Cat 4 with 150 mph (241 km/h) winds, but then stalled. This allows it to weaken the storm to 130 mph before landing. Cool waters in the wind rise to 130 mph. The part where rapid reinforcement occurs along the Zelia track, there is a recorded ocean temperature: about 31 degrees Celsius (88°F), i.e. 1 to 2 degrees Celsius (1.8-3.6°F) above average. According to the climate center’s climate change index: Ocean (Ocean CSI), this unusually warm may be 10 times more than anthropogenic climate change. This extra heat makes Zelia more likely to exacerbate quickly. The Climate Change Index is detailed in the 2024 paper published in the journal Environmental Research, “Attributes daily ocean temperature to anthropogenic climate change.”
Tropical cyclones have declined in Australia in recent decades
Although the most powerful tropical cyclones are getting stronger around the world, the frequency of tropical cyclones has been declining in the southern hemisphere, especially in the waters around Australia. According to the 2022 study by Murakami Island Heroki (Figure 2), this can be attributed to the dryness, increase in sunken air due to changes in atmospheric circulation caused by changes in atmospheric circulation due to the reduction of stricter air pollution The sinking air in the southern hemisphere.
