* WHAT...For the Coastal Flood Advisory, up to one half foot of inundation above ground level in low-lying areas near shorelines and tidal waterways. For the High Rip Current Risk, dangerous rip currents. For the High Surf Advisory, large breaking waves of 6 to 12 feet expected in the surf zone. For the Coastal Flood Warning, one to two feet of inundation above ground level expected in low-lying areas near shorelines and tidal waterways. * WHERE...Atlantic Coastal Cape May, Coastal Atlantic and Coastal Ocean. * WHEN...For the Coastal Flood Advisory, until 10 PM EDT this evening. For the High Rip Current Risk, through Friday afternoon. For the High Surf Advisory, from 8 PM this evening to 6 PM EDT Friday. For the Coastal Flood Warning, from 4 PM Wednesday to 1 AM EDT Friday. * IMPACTS...At this level, widespread roadway flooding occurs in coastal and bayside communities and along inland tidal waterways. Many roads become impassable. Some damage to vulnerable structures may begin to occur. Dangerous swimming and surfing conditions and localized beach erosion. Rip currents can sweep even the best swimmers away from shore into deeper water. * ADDITIONAL DETAILS...Significant beach erosion is likely through this week and into the weekend. Moderate tidal flooding could continue through Friday or perhaps longer. A Coastal Flood Warning means that moderate or major tidal flooding is occurring or imminent. Be prepared for rising water levels and take appropriate action to protect life and property. Follow the recommendations of local emergency management officials. Do not drive your vehicle through flood waters. The water may be deeper than you think it is. You will be putting yourself in danger and your vehicle may be damaged, leading to costly repairs. Visit the National Water Prediction Service at https://water.noaa.gov/wfo/phi for additional water level and flood impact information for your local tide gauge. Inexperienced swimmers should remain out of the water due to dangerous surf conditions. Always obey posted Beach Flags. If you enter the surf zone, always have a floatation device with you and swim near a lifeguard if possible. If caught in a rip current, relax and float and do not swim against the current. If able, swim parallel to the shoreline. If unable to escape, face the shore and call or wave for help.
