Re: SIO: GRANT - Moderate Tropical Storm

#23 Postby cycloneye » Thu Jan 01, 2026 9:30 pm

MODERATE TROPICAL STORM GRANT


Estimated maximum wind speeds (averaged over 10 minutes) at sea: 65 km/h.

Estimated maximum gusts at sea: 95 km/h.

Estimated pressure at the center: 999 hPa.

Position on January 2nd at 04:00 local time: 15.9 South / 67.6 East.

Distance from the coast of Réunion: 1370 km to the East-Northeast sector

Distance from Mayotte: 2440 km to the sector: EAST

Movement: WEST, at 6 km/h.

System information:

- Moderate tropical storm GRANT is located approximately 610 km northeast of Rodrigues.

- Grant is expected to continue weakening by Saturday, with tropical depression intensity forecast for Friday. It could even weaken to a tropical disturbance by Saturday. Its subsequent track is expected to pass more than 400 km north of the Mascarene Islands.

- From Sunday onwards, the intensity forecast becomes very uncertain: the majority scenario favoured by the current CRMS forecast suggests a system remaining weak until the beginning of next week, but this will need to be confirmed.

Information for Réunion and/or Mayotte:

- Regarding Reunion Island, according to the current preferred scenario and regardless of the intensity of the phenomenon, GRANT should circulate at the beginning of next week at a good distance to the north/northwest of the island without significant influence on the island.

- No influence is expected on Mayotte.

Information for other areas of the basin:

A passage near Saint-Brandon is expected between Sunday and Monday, possibly accompanied by heavy thunderstorms.
