Una ProceZIHón de los Fieles

and a mar de fondo event has been predicted to affect our coast during this weekend.

I don't know where the "mar de fondo" came from. All three of my wave forecasts have no event coming. The waves in Ixtapa are small.

One of my forecasts show a slight wave increase for the 14th-15th.

The warning comes from the Secretaría de la Marina. People I trust.
