Typhoon is an open-source weather application, forked from Stormcloud 1.1, which is not available for free. It permits the users to change the colors to integrate better with the system wallpaper and theme and adjust the application’s opacity.
The latest version available is Typhoon 0.8.9, which has been released a while ago, but now its PPA has received packages for Ubuntu 15.10 Wily Werewolf.
Typhoon is available via some third party PPA, so installing it on Ubuntu is piece of cake. All you need to do is add the ppa to your system, update the local repository index and install the typhoon package:
$ sudo add-apt-repository ppa:apandada1/typhoon
$ sudo apt-get update
$ sudo apt-get install typhoon
To remove typhoon, do:
$ sudo apt-get remove typhoon
The installation instructions should work on all the supported Ubuntu systems and derivatives: Ubuntu 15.10 Wily Werewolf, Ubuntu 15.04 Vivid Vervet, Ubuntu 14.04 Trusty Tahr, Ubuntu 12.04 Precise Pangolin, Linux Mint 17.3 Rosa, Linux Mint 17.2 Rafaela, Linux Mint 17.1 Rebecca, Linux Mint 17 Qiana, Linux Mint 13 Maya, Pinguy OS 14.04, Elementary OS 0.3 Freya, Elementary OS 0.2 Luna, Deepin 2014, Peppermint 6, Peppermint 5, LXLE 14.04 and Linux Lite 2.
