WPAC, Indian Ocean, and Southern Hemisphere Tropical Cyclones

Cyclone Idai, moving across the Mozambique Channel has completed an ERC and slightly reintensified to Cat 3. The internal structure of the cyclone has taken on annular characteristics. It is forecast to make landfall near the city of Beira in Mozambique. Despite Idai's intensity, flash flooding will be the greatest threat to the city and surrounding region. Certainly storm surge up the Pungwe River also poses a dangerous threat to life and property.cbcbcf34e90c34d9e415a82526c91493.jpg

Saw that this morning. Beautiful structure. I don’t really follow tropical outside of the Atlantic basin but this ERC got my attention momentarily.

ADT for Idai rebounded somewhat prior to landfall. JTWC dropped to 95 kts on the last advisory. However, the core may have regained some of that intensity as cloudtops cooled and the eye appeared less ragged. Though 95 or 105 kts isn't a huge difference, increasing convection in the eyewall versus eroding convection may have helped transport destructive gusts to surface.1436db2a83be34a884aa28c4d0ae5684.jpg

The INGC, Mozambique's governmental natural hazards and disaster mitigation agency is on the ground evaluating damage. There has been very little word out of there.

Idai's remnant low continues to sit and spin over Mozambique and Zimbabwe, pulling a strong moisture feed off the Mozambique Channel and Indian Ocean; daytime heating adding to atmospheric instabilty supporting intense convective plumes over the same locations, essentially firehose band precipation moving over the interior. Not to sound dreary, but I would be surprised if conditions in both countries do not escalate into an humanitarian crisis at this point. A trailing surface trough and unstable boundary appears to hold between the highlands and coastal region through Wednesday until Idai's remnant low completely dissipates/precipitates out.

On top of what has already fallen, here is the modeled ECMWF totals, the bulk which falls over the next 72 hours:05d667830260e5c33a65e72280d01a21.jpg

You guys are so dramatic. It's a population of 500,000, how is there "very little word out of there"?

Their comms infrastructure isn't like that found in the US. And there have been limited resources on the ground relaying out the imagery we are just now seeing above. It was a major hit on a populated area with extreme rainfall totals still accumulating. What's not to be dramatic about? There is very real possibility of significant loss of life and a humanitarian crisis unfolding in the coming weeks/months.

It's 35 inches of rain over a few days, and -75 on the Satellite Cloud Tops Alert. I'm confused about this though, how is there such little/devastating news about real people? It's a nonstory. People just sit in their homes while flood waters creep up on them at 1"/hr?

This may be a nonstory to you, but the situation is still unfolding. No, it's not like they're just sitting in their homes waiting to drown. But people may be displaced and surged/flooded urban areas, much more rural, are difficult to reach with roads and bridges impassable. The Yatumbe River is currently expanding out across its flood plain with heavy rains continuing to fall over its interior tributaries. What is modeled, an additional 500mm/20 inches on top of what has already fallen, possible through Wednesday.

News doesn't exactly flow out to Western media from this part of the world at a rapid pace like it does elsewhere. It's going to take days to weeks for resources to get out all that is happening there to verify what has occurred from a meteorological perspective; and again, a large fraction of those 500k people are currently displaced within ongoing inclement weather, which isn't exactly helping the spread of personal testimony and experiences without anyone able to reach them on the ground and report it.

I'm not going to stop posting or apologize for posting about this event regardless if it seems like I am being too dramatic.

Pretty unanimous global modeling on a sub 930 mb tropical cyclone traversing the Gulf of Carpentaria late week. Looks like double landfalls for Cyclone Trevor in Australia. The initial being eastern Cape York Peninsula coast late on Tuesday. Then reintensification transitioning into rapid intensification as the severe cyclone turns poleward in the Gulf of Carpentaria.

Situation seems similar to that after the 2004 earthquake, first reports are of only a few casualties, because the worst hit sites have lost communications entirely.

Looks to be very ugly.

Australia now has two intensifying cyclones. Positioned off the NW coast is Veronica, which is quickly consolidating a core and looks to become an intense cyclone in the near term. Likewise, Trevor, which is emerging over the Gulf of Carpentaria is quickly reorganizing after crossing the Cape York Peninsula. Both cyclones are unanimously modeled to become severe cyclones and there is even the possibility of an extremely rare occurrence of two Category 5s raging simultaneously near to the Australian coastline at once.2bc4b80367ab9164822a302e97402e2b.gif1e6538875460b5d104ba3f7f0a6a51d1.gif

Veronica is looking nasty and it's amazing how well trevor held together. He should reorganize quickly once he is away from land.

Per ADT, Veronica is the equivalent of a Category 4 hurricane now. JTWC forecast 140 kts. Aus Met is also forecasting a 5 on their scale. Should make landfall on late Saturday or Sunday.324fe9df346e499670d0453611bb3d50.gif65e21c32b2cad9688182f86bce121733.gif2736784543ef6438b4d735531433f388.jpg
