Observed and forecast tracks: southern hemisphere 2024-25

Click on the name of the tropical cyclone to see a chart of the observed track and forecast tracks from the Met Office global model. Verification statistics on each tropical cyclone are available upon request from tropical_cyclones@metoffice.gov.uk. At the end of the season a verification report on the performance of the Met Office global model will be published.

South-West Indian (west of 90°E)
Name & ID Start & end dates Central pressure, 1-/10-minute MSW Comments on Met Office global model forecasts
Ancha (01S) 01-04 October 992 mb, 50/45 knots The track of Ancha was well predicted with a slight slow bias.
Bheki (02S) 14-22 November 943 mb, 115/105 knots Track forecast errors were mostly low, except at long lead times due to a right-of-track bias in early forecasts.
Chido (04S) 09-16 December 935 mb, 135/115 knots A slow bias at longer lead times resulted in large track forecast errors.
Dikeledi (07S) 09-17 January 945 mb, 100/95 knots There was a slow and left-of-track bias resulting in large track forecast errors.

Note on estimated wind speeds

1-minute MSW: Maximum sustained wind (knots) averaged over one minute (JTWC Hawaii)
10-minute MSW: Maximum sustained wind (knots) averaged over 10 minutes (Southern Hemisphere RSMCs and TCWCs)

Note: Although 1-minute average winds should be stronger than 10-minute average, this may not be the case here since estimates are obtained from different warning centres using different analysis techniques.
