693 WHUS42 KMLB 240738 CFWMLB Coastal Hazard Message National Weather Service Melbourne FL 238 AM EST Sat Nov 24 2018 ...VERY LARGE SWELLS ROLLING INTO THE CENTRAL FLORIDA ATLANTIC COAST THIS MORNING... Data from NOAA buoy 41009 indicates very large northeast swells of up to 15 feet have developed over the local Atlantic waters. These very large swells will produce life threatening surf conditions today. FLZ047-054-059-064-141-147-250000- /O.NEW.KMLB.SU.Y.0007.181124T0738Z-181124T1500Z/ /O.NEW.KMLB.RP.S.0039.181124T0738Z-181125T0000Z/ Southern Brevard County-Indian River-St. Lucie-Martin- Coastal Volusia County-Northern Brevard County- 238 AM EST Sat Nov 24 2018 ...HIGH SURF ADVISORY IN EFFECT UNTIL 10 AM THIS MORNING... ...HIGH RIP CURRENT RISK IN EFFECT THROUGH THIS EVENING... The National Weather Service in Melbourne has issued a High Surf Advisory, which is in effect until 10 AM EST this morning. A High Rip Current Risk has also been issued. This High Rip Current Risk is in effect through this evening. * WAVES AND SURF...Very large ocean swells of 12 to 15 feet will produce large breaking waves of 7 to 10 feet. Numerous strong and dangerous Rip Currents will be present. The combination of swells and high astronomical tides will result in water runup to the dune line, along with beach erosion during the upcoming high tide. * TIMING...Water runup to the dune line along with beach erosion is likely during the upcoming high tide cycle centered around 830 AM. The threat for Rip Currents will be present all day, but be especially high during the outgoing tide this afternoon. * IMPACTS...Large swells could easily knock you down and make you more susceptible to becoming caught in the strong seaward pull of a Rip Current. Venturing into the surf is not recommended today. PRECAUTIONARY/PREPAREDNESS ACTIONS... A High Surf Advisory means that high surf will affect beaches in the advisory area...producing localized beach erosion and dangerous swimming conditions. There is a high risk of rip currents. Rip currents are powerful channels of water flowing quickly away from shore, which occur most often at low spots or breaks in the sandbar and in the vicinity of structures such as jetties and piers. Heed the advice of lifeguards...beach patrol flags and signs. Swim near a lifeguard. If caught in a rip current, relax and float. Don't swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and call or wave for help. && $$
