+Please create a github issue if you encounter any bugs or want to make suggestions.

+There are some known limitations with the tool at the moment:
+
+- There cannot be more than one critical storm for single duration. This is not likely to happen anyway, but will be fixed in future releases if there is interest.
+- Changing the default colour / layout of generated plots is not yet possible.  
+- All durations must have the same number of temporal patterns.
