This area is notorious for flooding after moderate rainfall. When we were kids my brothers, sister & I used to watch the cars trying to brave the flood water after a downpour, often getting stuck in the process.
I placed the cache when all was dry but a couple of hours later after a heavy shower there was already some flooding a few inches deep so I guess nothing has changed.
You may need wellies after rainfall but otherwise the cache is easily accessible even by wheelchair with care.
