Now that is an excellent eyewall. It’s hard to believe just 24 hours ago, Ambali was a mere 35 kt tropical storm, and now it’s probably well on its way to Cat 5 status.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

What an impressive intensification :eek:, this could be a category 5 IMO, the sad part is they probably won't called it
Edit: Models weren't bullish with this (no more than a tropical storm at peak) and now this is worth of a high end category 4, imagine what could happen with Belna that is expected to be stronger than Ambali according with models :eek:

Odd...the eye is cooling to single digit positive temps, yet the eyewall is looking excellent in microwave imagery with no signs of doubling up. Maybe this is an eyewall meld?

Models significantly underestimated this system, this is a sleeper. This is better than consistently hyping the intensity only to back off at the last minute.

Ambali went bonkers
The cyclone north of Madagascar looks ready to go bonkers as well

I’m in shock at how active the Indian Ocean has been and that the SWIO season is already going absolutely insane.

Meteo France in La Reunion just issued their advisory. They have it at 120 kts. They're the official agency of the basin. Could be 130-135 kts, though.

Now I can forgive them for that abysmal 100 kt estimate at 18z. Better late than never, although maybe it could be a little stronger.

However, the windshear is rising sharply and it may have begun to weaken.
