Australia’s east coast is closely watching Tropical Cyclone Alfred, which has been churning and strengthening over the Coral Sea. Although the storm is expected to stay offshore for now, it’s still set to bring gusty winds, rising swells and hazardous surf conditions to Queensland’s heavily populated coastline in the coming days.

Severe Tropical Cyclone Alfred is inching closer to the Queensland coast, bringing intense winds and wild surf. The system remains over the Coral Sea, with the Bureau of Meteorology forecasting strong to gale-force winds across the southern Great Barrier Reef Islands and extending to K'gari this weekend.

Satellite imagery can help determine the strength, size and cohesion of a storm. The stronger a storm becomes, the more likely an eye will form in the center. When the eye looks symmetrical, that often means the storm is not encountering anything to weaken it.

Severe Tropical Cyclone Alfred is a Category 3 system this Friday morning, after becoming as strong as Category 4 on Thursday night.

Tropical cyclone is the catch-all term for the powerful, spinning storms that feed off warm oceans and the strength of which is determined by wind speeds. The strongest are known as hurricanes in the Atlantic and typhoons in the Western Pacific and simply tropical cyclones in the South Pacific.
