The GOES-East water vapor image from 5:36 PM highlights a dry air mass over Central to South Florida, which explains the sparse cloud cover over the Florida Keys. Fresh to strong breezes will continue through Wednesday night. These conditions will ebb faster than earlier this year, as a trough responsible for the showers over Alabama is on track to bring moisture to the Florida Keys late this week.
A Small Craft Advisory remains in effect for all Florida Keys coastal waters. NE winds 20 to 25 knots, becoming northeast to east and increasing to near 25 knots across all marine zones.
