TROPICAL CYCLONE INFORMATION BULLETIN
Issued at 4:37 pm EST on Thursday 27 February 2025
At 4 pm AEST Thursday, Severe Tropical Cyclone Alfred (Category 4) with central
pressure 954 hPa was located over the Coral Sea near latitude 17.5 south
longitude 155.4 east, which is about 770 km east northeast of Mackay and 830 km
northeast of Rockhampton.
Alfred is moving south though the Coral Sea and is forecast to continue to move
general south and continue to strengthen during the rest of Thursday and into
Friday morning.
There is increasing confidence that Alfred will stay offshore of the Queensland
coast, however, there remains uncertainty as to how close to the southern
Queensland coast Alfred may come during next week.
Regardless of Alfred's path, increased coastal hazards for the southern coast
are expected. A large and powerful to potentially damaging easterly swell as
well as abnormally high tides are forecast to develop about southern Queensland
beaches from Friday or during Saturday. Refer to marine warnings and forecasts.
The next Information Bulletin will be issued by 11:00 pm AEST Thursday 27
February.

EYE SURROUNDED BY CMG THAT IS EMBEDDED WITHIN B RESULTS IN AN ENO OF 5.5
AND AN EADJ OF -0.5 GIVING A DT OF 5.0. THE MET IS 5.5 BASED ON A SLOWLY
DEVELOPING TREND IN APPARENT INTENSITY OVER THE PAST 24 HOURS. THE PT IS
ALSO 5.5. THE FT IS BASED ON THE MET DUE TO THE OBLIQUE VIEWING ANGLE
OF THE SYSTEM FROM G18 POSSIBLY VIEWING THE MID-TO-LOWER EYEWALL. IF
THE TRUE EYE TEMP IS ANY WARMER THE DT WOULD INCREASE.
