Morro Bay police have closed Embarcadero and Coleman streets along the city's waterfront as a precaution in response to the tsunami advisory issued today.
The rise in sea level was expected to reach the San Luis Obispo County coastline shortly after 9 p.m. National Oceanic and Atmospheric Administration officials expected the sea to rise about 24 inches at Port San Luis.
The advisory was issued for the entire California coastline and north along Oregon. The advisory was to remain in place into early-morning hours Wednesday.
In another precautionary move, some campers were moved to higher ground at Oceano Dunes state park earlier tonight.
