Chatham tends to benefit from storms moreso than other parts of Kent, particularly where I live (in the Weald of Kent). The UHI of London effect can create storms over London which then drift down the Thames Estuary, or equally during ENE shower trains the proximity of your location to the sea helps you receive the showers during their most intense stage. However when it comes to storms moving from the south, it all depends on whether they survive when they reach our shores. Otherwise it's just the south and east coasts of Kent that see anything, whilst the rest of us usually get just plain old rain.
