The strongest tropical cyclone of 2025 has developed
The last hurricane in the North Atlantic basin to reach such a deep pressure was Hurricane Milton, which hit 895 millibars (mb) at its peak.
A strong storm churning off the coast of Australia is becoming the strongest tropical cyclone of 2025 and the first Category 5 storm of the year. Cyclone Errol has intensified, with its central pressure reaching 919 millibars (mb) and sustained winds reaching 259 km/h.

The last hurricane in the North Atlantic basin to reach such a deep pressure was Hurricane Milton, which hit 895 mb at its peak. The tropical cyclone season in this region of the Southern Hemisphere typically runs from late October through May.
Despite its immense power, Cyclone Errol is currently a relatively small storm. Its compact size may actually facilitate further intensification as it moves over warm ocean waters. However, meteorologists predict that it will begin to weaken once it makes landfall, as the storm will encounter land and lose its energy source.

Tropical cyclones in the Southern Hemisphere, like Cyclone Errol, rotate in the opposite direction compared to those in the Northern Hemisphere, which rotate counterclockwise. This unique characteristic is due to the Coriolis effect, which influences storm patterns based on the hemisphere.
Timing and impacts
Cyclone Errol will still bring significant rainfall to the Kimberley coast area starting on Friday. Residents in this region should prepare for heavy downpours and potential localized flooding.
The sea surface temperatures surrounding Cyclone Errol are exceptionally warm, hovering around 30-31°C—well above the 26.5°C threshold required for tropical development. This warm water has fueled the cyclone's intensity.
Current forecasts indicate that Cyclone Errol is expected to make a left-hand turn toward the Kimberley Coast.
