In the second to the last paragraph on the cumulonimbus learning clouds section, you wrote shalter and I think you meant to write shelter. I do like all the new enhancements to Windy.

In the last hour, Hurricane Michael has made landfall and as a strong Cat-4 hurricane just short of a Cat-5 with 155 mph (250 kph) winds and gusts to 175 mph (280 kph). It is moving at a fast 14 mph (23 kph). The pressure was just measured at 928 mb, one of the lowest ever to hit a US coast even lower than Hurricane Katrina.

You can probably find out everything you want to know about the current Windy API4 at Windy API v4.

There are some Windy layers which cannot be changed when using an Android or iOS device. Rain Accumulation is one of them. If you would like the list of layers which cannot be changed, it is available at Overview of units used on Windy. If you aren't interested in looking up items like this (as most users would not want to do also), then make any of those changes using the Windy website using a browser. Changes made using a browser save to the cloud and will then be available when using either an Android or iOS app. If you cannot make a change using a browser, then submit a bug report.

I just opened Windy in my browser and changed my accumulation scale to mm.

Then I set my overall setting to mm for rain.

I closed the Windy tab and reopened it fresh and my settings were still both mm.

Then I left settings in mm but changed the scale to inches, closed and reopened Windy and Windy remembered both settings. Could this be browser specific? I am using Opera on a Mac. What do you use?

Ahh, found it. I was using an app initially but realize what you were saying once I launched my browser. Yes, it seems to be a mistake but you can change the number to 31.2 by adding a period to the number right there as just did. I agree that the default value is not correct.

Admins, take note!

Check out the video of Mike Seidel of the Weather Channel as he struggles to keep his balance during a faked Hurricane Florence segment. He clearly is struggling to keep his balance in the "fierce" wind until we see 2 guys in the background casually walking by not affected by the supposed fierce wind at all. Note in the upper left corner of the screen that the wind was only 29 MPH. A Weather Channel statement said he was tired and on slippery grass. Of course pavement was only a foot or two away from him. It is incredible that Mike Seidel and the Weather Channel faked this segment given all the actual severe weather in the area.

Shame on Mike Seidel and the Weather Channel.

Take some time and enjoy all the spoofs that have been posted already on YouTube.

Directions to set Main Menu Settings to your desired preference.

For this answer, I'll assume you are using an Android or iOS app and the main settings are in mm. Here is the process to change Main Settings to inches. The pictures are screenshots of my iPhone X but any Android phone should be similar.

First, click on the current layer icon to get to the Main Layer Menu.

Next you will see the Main Layer Menu.

Scroll the menu all the way to the bottom and click on Advance Settings.

You will then see the general Setting Menu.

Make sure the items in the red box are set to inches for Rain and/or Snow. Set any other general setting you wish to change. When you exit the Main Menu, all will be saved.
