ALERTE ROUGE EN COURS A LA REUNION

[Ptarmigan]

Gamede is quite large. It has gale force winds extending up to 375 miles from the center!

[Chacor]

Gamede is quite large. It has gale force winds extending up to 375 miles from the center!

600 km is the 30-kt wind field, not the gale-force radius. Gale-force winds probably extend slightly less far out than 375 mi.

[Ptarmigan]

600 km is the 30-kt wind field, not the gale-force radius. Gale-force winds probably extend slightly less far out than 375 mi.

That's still large. I've been through 30 kt wind and it's no fun for sure.
