The U.S. NHC is designated a regional hurricane center by the United Nations. Therefore, it measures, and offers advice to, other nations' meteorological services with regard to hurricane warnings.
A hurricane hunter aircraft measured Patricia (below) and found 200 mph -- the strongest winds ever measured by NHC -- in the storm which will hit the west Mexico coast this afternoon.
Here is a map of the hurricane warning area. I placed an arrow pointing to Puerto Vallarta to orient you.
I also liked the Hurricane Center's parting paragraph:
I'll update on the Texas rain threat this morning.
