Hurricane Michael continues to advance northward in the northern Gulf and is expected to make landfall this afternoon in the FL Panhandle. Peripheral squall like showers and storms will move north across east central FL today. These showers and storms will be capable of producing dangerous lightning strikes, wind gusts of 40 to 50 MPH and heavy rainfall in a short period of time, leading to accumulations of 1 inch with locally higher amounts that may contribute to flooding of low areas. An isolated tornado or two is possible in these squalls north and west of Interstate 4 where a marginal risk of severe weather is forecast. An isolated waterspout over the Atlantic waters is also possible. Shower and storm motion will be to the north/northwest at 30 to 35 mph as Hurricane Michael pushes northward through this afternoon. .RIP CURRENT IMPACT... Gusty southeast winds and long period swell will produce a Moderate Risk for rip currents. Rip current activity will be present all day, but is highest in the hours surrounding low tide, which occurs in the mid afternoon today. Always swim in sight of a lifeguard and never swim alone. .MARINE THUNDERSTORM GUST IMPACT... Gusty showers and storms associated with the outer rainbands of Hurricane Michael will be capable of producing wind gusts over 35 knots today over inland lakes, the Intracoastal and open Atlantic waters. Mariners should keep watch for quick moving showers from the south and seek safe harbor when skies look threatening. .WIND AND SEA IMPACT... Poor to hazardous boating conditions continue today with south to southeast winds of 15 to 20 knots producing seas of 6 to 8 feet over the coastal waters. A Small Craft Advisory remains in effect for nearshore waters north of Sebastian Inlet and for all offshore zones. Small craft should still exercise caution south of Sebastian for seas of 5 to 6 feet and SE winds 10 to 15 knots. .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY. Hurricane Michael will move quickly to the northeast after landfall, approaching the Mid Atlantic by late Thursday. Coverage of showers and storms will decrease through the weekend as dry air moves in behind a weak frontal boundary. Hazardous beach and boating conditions will slowly diminish through late week as Michael lifts to the northeast. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed today. Smith
