It never rains and then it pours and pours and pours and pours.

#ExtremeWeather event with multiple cyclonic storms hits drought stricken Madagascar.

Thread...

This rainfall forecast for Madagascar on Friday (10 days) was/is seriously dire. A waterlogged South Indian Ocean atmosphere has been forecast for some time to develop multiple tropical storms. And on Friday they arrived.

So far floods have produced rains killing at least 10 people in the Capital City, Antananarivo [Location: goo.gl/maps/NipR18bSo…] hahttps://www.africanews.com/2022/01/18/10-killed-by-floods-in-madagascar/

At 587k km2 Madagascar is larger than France with a pop. of 28 million.

Relief Web released a Red Cross "Emergency Plan of Action" document Friday.

The following three satellite animations show storm activity as the cyclone (Storm Ana) come on shore over night Friday, through to today

Here we see 24 hours from 10.30am Friday.

Here we see 24 hours from 10.30am Saturday.

And the 24 hours from 10.30am Sunday till this morning. Storm Ana has now arrived in Mozambique, and still appears to be fairly intense, in rainfall terms. #StormAna has never been a high intensity cyclone in wind terms.

While Storm Ana has now passed, unfortunately the weather pattern may well produce some more storms for Madagascar over the next fortnight. This IVWT (integrated water vapour) forecast is for eight days till February 1st.

This longer range 16 day forecast shows the forecast storm above arriving shortly after Feb 2nd, with a larger and stronger storm trailing in its wake.

This remains a situation worth keeping an eye on.

Rain, provided there is not too much of it and it is where it is needed could be beneficial for Madagascar.
