The CP guy just came through and said I should check tomzap for a message that revises the times. I think this may be what he meant. (Who knew the Civil Prot guys read our blogs...) He said a meter is about what they are expecting.

Warden Message

This Warden Message alerts U.S. citizens traveling to or residing on the Pacific coast of Mexico of a tsunami wave which is anticipated to hit the northern part of the Pacific coast starting at 8:50 am PST on March 11, 2011. A massive 8.9 magnitude earthquake hit the Pacific Ocean near Northeastern Japan at around 14:46 pm JST on March 11, causing damage with blackouts, fire and tsunami. The large earthquake triggered a tsunami warning for countries all around the Pacific ocean.

There is a general tsunami warning for the entire Mexican Pacific coast. Mexican Civil Protection recommends avoiding the beaches and remaining indoors. The Port Authority has closed the Port of Puerto Vallarta as a precautionary measure until further notice. The U.S. Consulate General urges American citizens to monitor local media sources for additional information.

According to the National Oceanic and Atmospheric Administration (NOAA), “sea level readings confirm that a tsunami has been generated which could cause widespread damage…A tsunami is a series of waves and the first wave may not be the largest. Tsunami wave heights cannot be predicted and can vary significantly along a coast due to local effects. The time from one tsunami wave to the next can be five minutes to an hour, and the threat can continue for many hours as multiple waves arrive. When no major waves are observed for two hours after the estimated time of arrival or damaging waves have not occurred for at least two hours then local authorities can assume the threat is passed. Danger to boats and coastal structures can continue for several hours due to rapid currents. As local conditions can cause a wide variation in tsunami wave action, the all clear determination must be made by local authorities.”

NOAA anticipates that the waves will arrive at the following local times:

Ensenada: 8:50 PST

Punta Abreojos: 10:38 MST

Cabos San Lucas: 11:15 MST

Socorro: 11:25 MST

Mazatlan: 12:04 MST

Nuevo Vallarta: Between 12:04 and 12:30 MST

Puerto Vallarta: Between 13:04 and 13:30 CST

Manzanillo: 13:30 CST

Acapulco: 14:05 CST

Puerto Madero: 15:40 CST
