Hi, the standard Cloud base [cbase] overlay in Windy is not one of Windy's better overlays. The 'criteria' are revealed in its very simplistic (and not very useful) display settings which are these:
As you can see the color variation is not helpful or logical and the increments used are also pretty terrible for meaningfully informing a VFR pilot of cloud base forecasts and the changes. It really only provides mildly useful information below 4,900 ft as everything from 4,900 to 26,200 ft is just shades of the same green-grey color - that's really not helpful.
So I created a much more detailed, fully linear (forecast display increment is accurate to +/-100ft) custom overlay with which to completely replace the standard one, which works very informatively and logically from 0 ft to 18,000 ft. As you will see, there's a massive difference in useful intelligible detail shown. The legend for this custom overlay is shown below, so have a good look at the comparison images with reference to this legend classification to interpret. The colors shade progressively and linearly in between these given color = altitude increments.
Here are some examples to contrast the differences:
Instructions on how to install this custom Cloud base overlay in Windy:
Directions to install a new custom overlay using the Browser version of Windy
Press “Menu” icon on main screen (see top left corner).
Go to the “Settings” Tab.
Go to “Customize Color Scale” option (near the bottom).
Select the relevant overlay title from the “Select Overlay” drop-down list.
Use the scroll bar to go down to the bottom of that tab's display.
Press on text Import/Export: [View Code], which then opens a small text box below it.
Select all of the existing text within that text box then delete it.
Then copy and paste the new custom text settings from this thread (as given below) and paste the full code text into the text box.
Then press [Import] ... and the new display will appear on the right side of the screen within a few seconds as it loads.
Exit the editor with the red 'X' button on its side. This will save the custom setting to your personal log-on account.
Repeat the process for each custom overlay which you want to install.
Note: That the custom overlays can only be installed within the browser version of Windy and are not able to be altered using the smartphone App version of Windy. You must use a full browser installed on your smartphone, tablet or PC to install these custom Windy overlays. However, once done the custom overlays will then also display within the App versions of Windy. Note also that if you clear the Windy cookies and cache files in your browser you may need to reinstall the overlays once again. And if you want to revert to the old setting just press the Load defaults button.
Here is the setting that you'll need to install to get this custom Cloud bases overlay into Windy's web browser version. Highlight all of the text within the box below and copy n' paste it all in as described in the instructions above.
These settings will only show in Windy if you've logged-in to Windy.
There are many very detailed custom overlays for Windy that you can install within the thread linked below, I've created new and very detailed overlays for all of Windy's overlay types, and they're all stored within the first two-pages of this thread:
I've also made a Cloud tops overlay, which uses the same color scheme as this Cloud Bases one, with the same altitude divisions, so you don't have to learn two completely different overlay layouts in order to understand them both.
Edited: To improve instructions.
I released a new Cloud base overlay setting here (17th May 2019):
“My children are still scared. They don’t want to go back home”

A mother narrates Cyclone Kenneth ordeal
By Joseph Scott, Mozambique
Zena Momade moved into a temporary shelter after Cyclone Kenneth destroyed her house. The day before Cyclone Kenneth hit Pemba district in Mozambique, Zena Momade and her family crowded around had crowded around the radio to get information on the impending disaster. According to Zena, who lives in Chibwabwari- an area along the Pemba coastline, many in her community were all convinced that information about the cyclone Kenneth was not true. And they can be forgiven for having not taken the news seriously. This was the first time in modern history for Mozambique to experience two cyclones in one season.
“It was unthinkable to ever imagine that a cyclone would hit our area,” she says. “But we found out the truth in a hard way.” Zena says on Wednesday, a day before the cyclone made landfall, the weather was fine. The kids were playing on the beaches that span the length of the coastline and fishermen were busy hauling their catch for the day.
Not a myth anymore
Things started changing the next day. Ghastly winds attacked the coastline and a drizzle that soon developed into thunderstorms warned them that the news about the cyclone was real. “The sky became very dark and everyone knew that the cyclone we heard on the radio was here. All of a sudden, we had heavy downpours and strong winds that lifted large waves in the ocean. It was a scary sight,” says Zena. “The waves were like a giant fish swallowing anything on its path. All the boats at the shore were washed away. In no time, the place was heavily flooded, and all houses close to the shoreline were also washed away,” she recalls.
Zena, a mother of three says she will never forget the look on the face of her children during the storm. She says they were all trembling as they had never seen such a frightening spectacle in their lives. Her eldest daughter, who is 10, broke down into tears as wind tore through their house. “I was helpless,” she says. “My husband was at work and I had to move the kids all alone to a safe place. Fortunately, we got into one of the buses that service our route and escaped to Pemba town.”
A place far away from home
Zena and many families made it safe into Pemba and they were accommodated at one of the temporary shelters provided by government in the city. Life has not been easy for Zena and other families staying at the shelter as they feel it’s too crowded. The centre is hosting 1,528 people and 805 are children. “There is no privacy here,” she says. “There are as many as 15 families sleeping in one hall.” Food is also a problem, she says. Many families didn’t manage to rescue their food reserves and now they rely on the communal meal that is offered once every day. And it’s usually rice and beans, nothing else. “The food is not enough. We could have at least wanted a change in diet but we don’t have control over that,” she says.
Plans for returning home
Since the cyclone destroyed their home, Zena’s husband has visited the place twice to clear the debris so that they can rebuild again. But Zena thinks the place is not good for raising their children as it is too dangerous. “Yes, it’s our land but I think we should move to another place,” she says. “The kids are still scared and they are always telling me that they don’t want to go back. They fear that the cyclone will come back again.”
Cyclone Kenneth: Militant attacks in Mozambique kill seven, threaten voter registration

Suspected militant attacks in Mozambique have been hindering aid delivery to victims of Cyclone Kenneth, which killed 41 people
Suspected Islamists have killed seven people in northern Mozambique in weekend attacks, threatening aid to victims of Cyclone Kenneth and paralysing ongoing voter registration for October elections, local sources said on Monday. Islamist fighters have terrorised remote communities in Mozambique's gas-rich, Muslim-majority Cabo Delgado region since October 2017, killing around 200 people and forcing thousands from their homes.
Between Friday and Sunday at least four separate villages were attacked in northern Cabo Delgado, local sources said. "Armed men invaded the district of Meluco, specifically the village of Minhanha, killed three people, and burned about 100 houses on Sunday night," a local source, who did not want to be identified fearing retaliation, told AFP. Sunday's attack followed another on Saturday that killed a teacher riding a motorcycle and three other people who were burned to death in Macomia district.
The attacks were the first since Cyclone Kenneth smashed into the country's northern region on April 25, leaving at least 41 dead and more than 240,000 affected. The delivery of aid to cyclone-hit areas has been underway, but the attacks put aid distribution at risk while they "paralysed" voter registration. "Insurgents invaded the villages of Iba and Ipho, in the district of Macomia," Magda Mendonca from the Public Integrity Center, an anti-corruption NGO that is also an election observer, told AFP. Mendonca said the attackers "plundered property without causing human casualties," but added they "paralysed an ongoing voter registration."
"The successive attacks are disturbing the voter registration process in the region," Mendonca said. General elections are scheduled for October 15. On Friday, suspected Islamists also attacked another registration centre in the city of Nacate, also in the Macomia district. According to local sources, "the gunmen vandalised equipment without causing human casualties." Macomia was hit by the second cyclone to strike Mozambique in six weeks, after Cyclone Idai which killed more than 600 in the central parts of the country.
The possibility of more heavy rain persists for northern and central Tanzania and possibly more rain in NE Mozambique later in the week too.
Just click on the map where you want to get weather forecast. You should have a picker at this place with a yellow arrow. Click on the arrow and you should see the time slider and the weather diagram for this place at bottom of page.
Sort of. Within the desert-like interior the air at 600 to 700 hPa is more indicative of what occurs under a winter High pressure system's descending air, with low winds over a rapidly cooling terrain and mostly clear sky. Then surface layer land breezes blow the descending cold air towards the warmer coastline during early morning hours.

That would be interesting to have a model altitude map, but more useful would be to show the model altitude on Meteogram for the chosen location, for each selected model.
You can’t get Windy probably because of the 100kbps limit of your One Fleet device.
However do you receive other websites, with mainly text and few images per page? Windy is mainly full screen images with animation which probably require more bandwidth ressources. But I’m not a specialist about these questions.
Et bon vent sur votre superbe plan Newick !
Interested to have the same very good large scale base map (transparent with shaded coastlines) that you guys have produced to add over the satellite data on our real time satellite data maps : https://odl.bzh/4h7yWnLW. Can this layer be shared with us, either the source or the tile pyramid ?
Thanks in advance !
