Powerful and large Hurricane Irma will strike southern Florida this weekend.
With regard to track, anywhere in southern Florida is fair game at this point. The hurricane is larger than average so widespread damage similar to what happened with Harvey in and around Rockport, Texas (see below) a few weeks ago will occur over much of southern Florida.
Ground zero for landfall will experience the worst damage. Fortunately, enough notice has gone out on this storm that folks have had a chance to get out or prepare. In case the message was lost, all coastal areas of southern Florida should have been under the assumption that landfall was possible and should have taken the appropriate steps.
One important message today would be: don’t let further weakening of the storm this afternoon cause you to drop your guard! Interactions with Cuba and the current eye wall replacement cycle will both cause Irma to stumble a bit today. But very warm ocean temperatures and favorable upper level winds can fix this in a hurry by Saturday.
Property damage will be high and fairly widespread. The radius of winds of tropical force (about 40 mph) will cover all of southern Florida. Hurricane force winds or greater ( about 74 mph) will affect nearly all of southern Florida, depending in the exact final track.
Hopefully, awareness will save a lot of lives with this storm.

The NOAA recon plane has also been releasing ocean probes – found very warm sea-surface temperatures of 29.5°C just ahead of #Irma.
