The National Hurricane Center has posted an advisory here on Hurricane Matthew, which is currently a category 4 storm with sustained winds of 140 mph. The Caribbean is likely to take a hard hit, but beyond that they're not sure where Matthew will go. North is pretty much a given. You can take a look at the latest projection cone here, and I strongly recommend everyone in the southeast keep an eye on this one.
If you're ever in or around the path of a hurricane, you should know your route out if you will be facing an evacuation. Florida residents, you can find yours here by county. If you're going to stay home and hunker down during the storm, it's absolutely vital to have a disaster kit ready, including enough drinking water and non-perishable foods in the event you're cut off in the aftermath. I can speak from personal experience on this; after four hurricanes in a row hit us back in 2004, we felt very lucky that we had prepared so well in advance. We lived without power and running water for 21 days until they finally cleared the roads enough for us to drive out and restock.
I live in a rural area, so if we take a hit here from Hurricane Matthew it will probably be a while before our power and cable service are restored. I'll report in when I can. In the meantime, everyone in the danger zone please prepare for this, and be safe.
