MIAMI (CBSMiami) -- The window to finish all preparations ahead of Hurricane Irma is rapidly closing.
Overnight Friday night, the first outer bands from Irma will move through the area bringing with them periods of heavy rain and tropical storm force winds. The wind may first be gusting over 40 mph but will become sustained at that speed overnight Friday to early Saturday.

During the day Saturday it will become nearly impossible to do anything but simple final preparations indoors. Make sure that you are where you want to be for the duration of the storm.
As the bands of rain increase Saturday afternoon and evening the wind will continue to gust and increase in speed throughout the night. The wind will become sustained over 74 mph Saturday evening and only increase from there prior to the potential landfall of Irma.
Saturday night as the wind increases it will create life threatening storm surges along the Keys and coast with some areas possibly seeing surge heights close to 10 feet. The wind and waves may act to push the water well inland and combined with the heavy rain will lead to widespread flooding.
The potential landfall is expected to occur very early Sunday morning. Even without a direct hit in South Florida the massive size of Irma will lead to widespread hurricane force wind and higher gusts. The peak of this occurs Sunday morning with the storm moving north of the area by Sunday evening.
The wind will gradually diminish beginning Sunday night with a slow improvement Monday.
