What, impacts and precautionsHide details
What
Northeast winds 20 to 25 kt with gusts up to 30 kt and seas 6 to 9 ft expected, highest seas in the SE Gulf and Straits of Florida.
Impacts
A Small Craft Advisory means that wind speeds of 20 to 33 knots, or seas of 7 feet or greater, are expected to produce hazardous conditions for small craft. These hazardous conditions may result in poor vessel handling and steering response, broaching, overturned dinghies and kayaks, slips and falls on slippery decks, rub damage along docks and seawalls, swamped bows at reef tract mooring balls, and dragging anchors.
Precautionary actions
Inexperienced boaters, especially those with smaller vessels, should avoid operating in these conditions.
