@AL-LL, the National Weather Service forecast, an actual human reviewed forecast instead of these computer only forecasts, is currently suggesting that the 2' seas will already have built by Sunday.
It is still too early to know whether Sunday or Monday will be better.
If this weather event happens faster than forecast Monday will be an excellent crossing day. If it happens slower Sunday will be an excellent crossing day. If the forecast holds Tuesday may be the day and you might be forced to enjoy the beach in Fort Lauderdale for a day.
