Looking at the latest IR and visible imagery, I have to say, I'm not blown away by the system's presentation. It's kind of blah.

It's almost the time of the day where you have to switch to visible. Cyclones just before sunset are like girls/guys after a few beers.

Starting to really look good. If it can stay off shore a eye may develop within the next 24 hours. I'm thinking 80-85 knots if that occurs, but if it moves closer to shore then no.

It basically looks like its about to make landfall:

Looking at that loop you can see a "jump" to the NW- and it looks like it will make landfall overnight.

Turning northwestward and scraping the coastline. Also the eye formed faster then I thought, so I'd estimate the winds now near 80 knots.

The 2 am PDT advisory has the cyclone very close to the coast, with the center only 15 mi S of Manzanillo. Motion is NNW and the center should pass over or near the city in the next few hours.

It has continued to strengthen, now up to 977 mb/80 kt, with a 20-25-nmi-wide eye. The Discussions says:

THE INITIAL INTENSITY IS RAISED TO 80 KT... AND THIS COULD BE CONSERVATIVE. CLOUD TOPS IN THE EYEWALL ARE COLDER THAN -80C...AND THE CIRRUS OUTFLOW IS GOOD IN ALL DIRECTIONS.

....

THERE IS A CHANCE FOR ADDITIONAL STRENGTHENING THIS MORNING...AND THE MAXIMUM WINDS COULD REACH 85-90 KT BEFORE THE CENTER INTERACTS WITH THE COAST OF MEXICO.

Manzanillo must be getting pretty raked right now, but unfortunately the two stations in the city are not reporting. Boo hoo. :(

As per the 5 am PDT advisory, Beatriz has made landfall with an estimated intensity of 977 mb/80 kt-- a strong Cat 1.

The latest position (19.4N 105.0W) is just inland, ~50 mi WNW of Manzanillo, which most certainly experienced the hurricane's core. The cyclone has essentially been moving parallel to the contour of the coastline, scraping a large area with hurricane winds. Judging from the plots, the landfall point was very close to the Colima/Jalisco state line:

Beatriz's track is remarkably similar to the last hurricane to hit this region-- Hernan 1996 (also a Cat 1). And, in fact, this sort of track-- moving parallel to (and scarping the coast) at a weird angle-- is very typical of landfalling EPAC cyclones:

quite similar. it looks like it was going to parallel the coast then took a quick jump north over land. it that area mountainous just inland?

I've seen people mention that theory on occasion, especially with regard to Hispaniola (in the NATL).

cant remeber the name, but there was one a few years ago that got pulled into the yucatan and got stuck there for a few days, lili?
