The latest tsunami warning message from the West Coast and
Alaska Tsunami Warning Center (2:30 a.m. PST, and first posted
by the National Weather Service) includes expected first arrival
times for several locations along the coast: Crescent City (Del
Norte County): 7:23 a.m. San Francisco: 8:08 a.m. (Here's the

Crescent City to 2 to 3 feet along the Sonoma, Marin, San
Francisco, and San Mateo coasts. Earlier: 1:45 a.m. PST message
