Just speaking about WPB & Jupiter,,,,the GOOD news is Lk Okee is at 13.5ft and usually at 16ft plus at labor day. What this mean is since it's so low, they are NOT opening any flood gates >> and opening those destroys our viz for weeks and weeks. Since this storm is moving quick(1 day over land rather than 3), I would expect that the clean water from the un-affected keys will ride the currents north to us and 3 days after the storm crosses, we should be in very good viz !! But if they open the S155 gate along with all the S40-S49 gates then we're toast until they close them. But with Lk O so low, we are gonna be in great shape for diving.
South Florida Mismanagement District has already begun to lower the canals. I dont know if this is only Broward and Miami-Dade.
