The 2 am PDT package has TS Adrian at 50 kt and strengthening. The Discussion is quite bullish Re: RI-- with some unusually aggressive language:

THE RAPID INTENSIFICATION INDEX OF THE SHIPS MODEL SHOWS AN 80 PERCENT CHANCE OF 30 KT OF STRENGTHENING DURING THE NEXT 24 H...AND A 77 PERCENT CHANCE OF 40 KT OF STRENGTHENING. A NEGATIVE FACTOR CONTINUES TO BE DRY AIR TO THE WEST OF THE STORM...WHICH THE SHIPS MODEL SUGGEST COULD AFFECT THE SYSTEM AFTER 24 H. THE NEW INTENSITY FORECAST CALLS FOR RAPID STRENGTHENING FOR THE FIRST 24 H...FOLLOWED BY A SLOWER STRENGTHENING RATE FROM 24-48 H IN ANTICIPATION OF DRY AIR ENTRAINMENT.

They bring it up to a solid 90 kt within 48 hr. If this cyclone were close to-- or heading toward-- land, this would be a tense situation.

TS Watch issued for parts of Mexican Coast...

THE GOVERNMENT OF MEXICO HAS ISSUED A TROPICAL STORM WATCH FOR THE

COAST OF MEXICO FROM ACAPULCO WESTWARD TO PUNTA SAN TELMO.

A 1059 UTC SSMI PASS SHOWED WHAT MIGHT BE THE BEGINNING OF A BANDED

EYE FEATURE. IN ADDITION...THIS PASS AND RECENT VISIBLE IMAGES

SUGGEST THAT THE CENTER HAS JOGGED NORTHWARD OVER THE LAST SEVERAL

HOURS...AND THE LATEST 12-HOUR INITIAL MOTION ESTIMATE IS 340/5.

ALTHOUGH THE STORM HAS CHANGED ITS HEADING OVER THE PAST 6 HOURS OR

SO...THE OVERALL TRACK FORECAST PHILOSOPHY IS UNCHANGED. A GENERAL

SLOW NORTHWESTWARD OR NORTH-NORTHWESTWARD MOTION IS FORECAST FOR

THE NEXT 12 TO 24 HOURS. BEYOND THAT TIME...A TURN TO THE

WEST-NORTHWEST WITH A SLIGHT INCREASE IN FORWARD SPEED IS

ANTICIPATED AS A MID-LEVEL RIDGE STRENGTHENS TO THE NORTH OF THE

TROPICAL CYCLONE. THE OFFICIAL FORECAST HAS BEEN ADJUSTED TO THE

RIGHT...OR NORTH...MAINLY DUE TO THE INITIAL MOTION AND POSITION.

THIS PUTS THE OFFICIAL FORECAST CLOSER TO...BUT STILL TO THE LEFT

OF...THE MULTI-MODEL CONSENSUS.

Winds are up to 60 kt now, and they take it up to 95 kt (almost Cat 3) by 48 hr.

The N jog is interesting.

100kt is my guess for peak strength.

I still think the track in the 3-5 days will be adjusted southward...~0.5-1 degree south of Socorro island.

Visible imagery suggests overshooting tops and IR show clouds are cooling. The stage is set for some rapid intensification this evening and overnight...

Yeah, but it's not close to getting the optimal "ring" pattern. If it closes off an eyewall, then we can start talking about RI.
