Daniel, I would just trust that the Caymen Island Mets are getting info from NHC that they trust. There is a big difference between the general public taking a downgrade the wrong way and an official government forecasting service. I don't think you are giving the Meteorologist there enough credit by saying they are taking the storm lightly becuase they downgraded warnings. They looked at the data and are feeling that the worst they might see are some TS storm force winds, but do not consider it an absolute based on the forecast. Its not like they are just sitting there looking at the public advisories and saying, 'Oh well, its just a TS. We can drop our warnings.' They comminicate with the Hurricane Center too.
