Out of curiosity I have recorded the early morning Weather Channels broadcast up here in Alaska while I was sleeping and it does appear that all the rain you are getting isn’t from Isaac.
The real rain is coming, might be some record rainfall in a lot of places.
right now its calm in Islamorada around marker 86,which is 86 miles from where Stephany Abrams is at the Southernmost buoy in Key West.An hour ago it was howling.
