How to override hook_menu from weather module

I'm trying to override the paths being set by the weather module e.g. example.com/weather/SomePlace. Reason being I already have content with URLs such as example.com/weather/tide-times

I have tried using:

function MY_MODULE_menu_alter(&$items) {
 	dsm($items);
    // Unset weather paths
    unset($items['weather']);
    unset($items['weather/autocomplete/%']);
    unset($items['weather/%/%menu_tail']);
  }

And clearing the cache, but it doesn't seem to be doing anything.

I've even tried commenting out all the $item definitions in the Weather module itself, which didn't help.
The only thing that seems to work is disabling the weather module.

Any suggestions?
Thanks
