If there were only yellow warnings for this depression then evidently it would not have fit the criteria:
"A storm will be named when it has the potential to cause an amber 'be prepared' or red 'take action' warning.
Other weather types will also be considered, specifically rain if its impact could lead to flooding as advised by the Environment Agency, SEPA and Natural Resources Wales flood warnings. Therefore 'storms systems' could be named on the basis of impacts from wind but also include the impacts of rain and snow."

So far I have not seen any named outside of November-March.
