Bryan suggests that South Floridians begin now to prepare in advance for the following reasons.

 Bryan says…
1. For a big storm like Irma, you need enough water to drink for 7 days. The water does NOT have to be bottled. You can simply buy water containers and fill them with tap water. 
2. Get a plastic sheet to line the tub. Then you can fill your tub with water without it leaking out. You’ll use this to flush the toilet and for basic cleaning if the water goes out.
3. Have enough food on hand to eat for 7 days – food bars and other packaged food is good.
4. Buy a large number of Ziploc-like plastic bags – large and small. You’ll use them to protect papers and other valuables AND you’ll fill them 3/4 full of water and stuff the freezer full. Do that by midweek to be sure they are frozen when/if the power goes out over the weekend. It will keep the refrigerator colder. Do NOT set your fridge on the lowest setting.
5. Get a portable radio that receives AM and FM. NOAA radio is good, but doesn’t get you information on evacuations and other instructions. Get batteries.
6. Get LED flashlights and/or lanterns. They run forever on fewer batteries. But you still need plenty of extra batteries.
7. Get large plastic bags. They are invaluable for keeping valuable things dry if you have a leak.
8. Get large plastic boxes. If you put your valuables, photos, and papers in plastic bags inside the boxes, they will likely be okay.
9. Get plastic sheeting and plenty of duct tape. 
10. Do your laundry this week!
In Florida, due to the large number of people that may have to prepare, good sense says to do it early. It is impossible to know how bad the hit will be, but all of the evidence points to a significant threat.
