Small Craft Advisory issued October 1 at 9:52AM EDT until October 2 at 6:00AM EDT by NWS Key West FL
* WHAT...East to southeast winds near 20 knots. * WHERE...Gulf waters beyond 5 fathoms including the Dry Tortugas. * WHEN...In Effect. * 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.
Inexperienced boaters, especially those with smaller vessels, should avoid operating in these conditions.
