Although the storm's exact path is not yet know, some meteorologists have said it's possible it could hit Florida, Georgia, the Carolinas, and Alabama this weekend.
In these states, residents are doing their best to prepare their homes to mitigate flood and wind damage, like securing rain gutters, clearing clogged drains, installing sump pumps, unplugging appliances, and reinforcing doors and windows.
According to the Department of Homeland Security (DHS), there is one thing you shouldn't do, however: Apply duct tape to glass windows.
Now a Category 4 storm, Irma has sustained wind speeds of 150 mph, with the potential to make homes unlivable for months. If extreme winds bust through windows with tape, it could cause the glass to break into larger, deadlier shards.
The best DIY alternative is boarding up your windows with plywood (preferably at least 5/8 inch thick) and caulking the perimeters to help keep out water. And though these are not a last-minute solution, you could also invest in wind-resistant windows or pull-down storm shutters, which need to be retro-fitted ahead of time.
