Bento is forecast to become a strong cyclone in 4-5 days.

[HURAKAN]

If I'm not wrong, this is almost the same place where the previous cyclone formed, right?

If I'm not wrong, this is almost the same place where the previous cyclone formed, right?

Yes almost at the same track.

Bento is now a cat 2 cyclone and is forecast to be a cat 4.

[Gorky]

From the satellite pictures of this cyclone, it looks a whole lot stronger than a Cat2 :O Perfectly formed, small eye, on such a large storm usually indicates cat4+ from experience.

[cycloneye]

I mistaken myself as it is a cat 3 105kt as I thoughted the 105 was at mph but yes it is a very strong cyclone now cat 3.

[James]

Wow, talk about explosive intensification. I know I'm speculating, but does anyone think it has any chance of nearing CAT 5 status?

[cycloneye]

22/2030 UTC 8.4S 76.4E T5.5/5.5 BENTO -- South Indian Ocean


102kt winds by sat estimates.

[Gorky]

Well it was a 22z image I was looking at. Didn't see a 2030z to compare it with. By the way, wher edo you get these dvorak intensity estimates from?

Thanks for the link. I've been looking for that page for a while

[cycloneye]

Will be a cat 4 at next warning #8 120kt and 922 mbs wow what a cyclone.

Will be a cat 4 at next warning #8 120kt and 922 mbs wow what a cyclone.

Is interesting how this cyclones go through this EXPLOSIVE CYCLOGENESIS that in a matter of hours they become monsters. Is there any weather observatory that we can look at in Diego García?

Just as I thought. Everything about the latest sat images screamed at least cat 4 to me. The ye became real prominent over the space of no more than 4 or 5 hours, on poleward outflow is amazing which helps rapid intensification. Jsut out of interest, where did you get this advanced information? Sorry to ask all these questions but I'm building up a series of TC/Typhoon/Hurricane site bookmarks and obvioously you have found a page I havn't
