Best website to lookup weather in Tokashiki / Zamami

Okinawa weather does seem pretty bad whenever I check, constant storms/rain.

Is there a reliable website I can use to see weather conditions for Zamami or Tokashiki Island? We can only go to either on Friday 6th or Saturday 7th November. So obviously if weather will be bad, we will probably skip it.
