The county where I live has an excellent Hurricane Guide on line with safety advice and preparedness checklists that might be helpful wherever you happen to be. Among other items, the guide recommends that you know in advance where
your nearest emergency shelters are located. If you have a 'special
needs' person under your care, find out where an appropriate shelter for
the person might be located. Our county has several shelters, but just
one that is specifically equipped for 'special needs' residents who
have registered in advance.
Registration is a precaution, whether you will need to use the shelter
or not. Just as importantly, the county has instruction on how to
register for transporation to shelters, including 'special needs' transportation.
Our county accepts physician approved special needs registrations up until the hurricane warning is issued, so you don't want to wait until there's actually a problem to start thinking about this.
Also, prepare emergency medicines and foods in advance, especially if the person under your care has diabetic or other considerations.
But remember, once a warning is issued it's too late to register. So plan in advance.
