From the Keys Tourism site:
In the wake of Hurricane Irma impacting the Florida Keys, infrastructure evaluations and restoration efforts are underway, according to Keys officials.
While residents and business owners were permitted back into the Upper Keys on Tuesday, visitors have been asked to postpone any near-term plans to vacation in the island chain.
Some areas of the Keys are likely to be ready to accommodate visitors before others. An exact reopening date for all regions is not yet known, but Key West city officials expect their island will open by Fantasy Fest, the annual costume and masking festival that is set to start Friday, Oct. 20.
