Disclaimer: Storm Surge Threat for Lake Okeechobee is not currently depicted in this product. It is assumed surge impacts will remain confined to areas inside the Levy and therefore of little to none impact to surrounding areas. Should there be a concern for a breach in the dike impacting population surrounding Lake Okeechobee, that concern will be expressed via the hurricane local statement and most importantly the issuance of Flash Flood Watches and/or Warnings as needed in coordination with the US Army Corp of Engineers and the surrounding counties.
