After a volcanic eruption near the Pacific nation of Tonga this morning, San Luis Obispo County saw high water levels but no major damage or flooding.

The eruption led to a tsunami advisory for the California coast, in which people are advised to avoid the ocean and waterways due to strong currents but are not told to evacuate.

No major flooding or damage has been reported in the are so far, but Port San Luis did report flooding up to their parking lot.

Port San Luis had some of the largest reported surges of water in the state, according to SLO County Office of Emergency Services on Twitter. The area reported a 3.1 foot surge from the event.
