Coast Guard advises the public of severe weather conditions in California harbors

national weather serviceLOS ANGELES — The Coast Guard advises the public to exercise caution when in and around central and southern California harbors. A combination of larger sea swells and tides are occurring due to the effects of several severe weather systems moving through the area.

Shoaling has been reported in Morro Bay on both sides of the channel between buoy 4A and buoy 5, with reported water depth in the channel of approximately 16 feet at mean low water. Ventura Harbor Patrol has also reported significant shoaling on both sides of the entrance to the harbor. They have reported that the channel is approximately 30 feet wide and 15 feet deep, with breaking seas inside the harbor.

The Coast Guard would like to warn boaters that weather and seas could impact harbors and waterways throughout central and southern California. Mariners are advised to contact local harbormasters, or the Coast Guard to determine the status, as some harbors are advising mariners not to transit through or in.

The National Oceanic and Atmospheric Administration has issued a High Surf Advisory that will remain in effect through Tuesday afternoon. Hazards include breaking surf of 6 to 10 feet with max sets to 12 feet on south facing beaches. There will be a high risk of strong and frequent rip currents, elevated surf and beach erosion. Caution should be used when on or near the water. Stay near occupied towers and never swim alone. If caught in a rip current, swim parallel to the shore.

The Coast Guard encourages all boaters and beach goers to prepare for the potential hazards and keep advised of weather changes through the National Weather Service and to monitor VHF-FM channel 16 for the most current safety advisories.

The Coast Guard urges mariners to always:

  • Stay Informed – The public should be aware of weather conditions and monitor the progress and strength of the storm through local television, radio and internet. Check the current and expected weather and water conditions before heading out, and be aware that weather conditions can quickly change.
  • Wear life jackets while on the water.
  • File a float plan with friends, family members and local marinas before heading out. The list should include the number of passengers aboard the vessel, destination and expected time of return.
  • Always have a working marine-band radio on board.
  • Carry marine flares on board the vessel.
  • Ensure bilge pumps are operational and vessels are secure for heavy winds and rain.
