Instruction: 
A Coastal Flood Watch means that conditions favorable for flooding are expected to develop. Be prepared to begin taking appropriate action to protect life and property. Follow the recommendations of local emergency management officials. Be sure to check the latest forecast from time to time in case a warning is issued or any new information becomes available. 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. 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.
