[bombarderoazul]

Whoa!, this storm is dangerous!

[Matt-hurricanewatcher]

Its moving northwest right now in moving closer to shore. The northern or northeast eyewall might make landfall.

HURRICANE JOHN DISCUSSION NUMBER 10
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL EP112006
200 PM PDT WED AUG 30 2006

JOHN REMAINS A DANGEROUS CATEGORY FOUR HURRICANE THIS AFTERNOON.
VISIBLE IMAGERY SUGGESTS THAT JOHN IS UNDERGOING A CONCENTRIC
EYEWALL REPLACEMENT CYCLE...AND THIS WAS ALSO EVIDENT ON A 1520 UTC
SSMI MICROWAVE PASS. BOTH THE OCCURRENCE AND TIME SCALE OF THESE
EYEWALL REPLACEMENT CYCLES ARE ALMOST IMPOSSIBLE TO PREDICT. IN
ANY EVENT...CONSIDERING THE CURRENT INNER-CORE STRUCTURE OF THE
HURRICANE...NO CHANGE IN INTENSITY IS INDICATED FOR THE EARLY PART
OF THE FORECAST PERIOD. SOME INCREASE IN STRENGTH IS POSSIBLE ONCE
THE EYEWALL REPLACEMENT HAS ENDED. THE HURRICANE WILL REMAIN IN A
LOW SHEAR AND WARM WATER ENVIRONMENT FOR THE NEXT 72 HOURS. THE
ONLY INHIBITING FACTOR WOULD APPEAR TO BE THE INTERACTION WITH
LAND.

THE INITIAL MOTION IS 310/12...A LITTLE FASTER THAN IN THE PREVIOUS
ADVISORY. THE FORECAST TRACK IS ESSENTIALLY AN UPDATE OF THE
PREVIOUS FORECAST...AND THE REASONING IS BASICALLY THE SAME.
JOHN SHOULD CONTINUE TO MOVE TOWARD THE NORTHWEST AND AROUND THE
SOUTHWESTERN PERIPHERY OF A MIDDLE- TO UPPER-LEVEL RIDGE OVER
NORTHERN MEXICO...PARALLEL TO BUT VERY CLOSE TO THE SOUTHWEST COAST
OF MEXICO. ONLY A SLIGHT WOBBLE TO THE RIGHT COULD BRING THE CENTER
ASHORE IN THE HURRICANE WARNING AREA.

THE GOVERNMENT OF MEXICO HAS ISSUED A HURRICANE WATCH OVER PORTIONS
OF THE SOUTHERN BAJA PENINSULA...AND EXTENDED THE TROPICAL STORM
WATCH OVER MAINLAND MEXICO.

THE UNITED STATES AIR FORCE RECONNAISSANCE AIRCRAFT WILL BE
INVESTIGATING THE HURRICANE TOMORROW AT 1800 UTC.

If this makes landfall, it will likely be a very devastating storm. There will be no John in 2012 should he turn right.

[JonathanBelles]

john is the one who made it across the pacific right? if so it should have already be retired.

[Brent]

If this makes landfall, it will likely be a very devastating storm. There will be no John in 2012 should he turn right.

There probably won't be another John anyway, not if it follows the track and hits Cabo San Lucas as a Cat 4 as expected.

Also, the 2am position tonight is only 40 miles SW of Manzanillo. Eyewall will likely be onshore.

[Dean4Storms]

Impressive EPAC Hurricane, seems the Atlantic is getting all the bad shear this year.

[cycloneye]

Acapulco radar shows the impressive eye.

[Dave C]

here's a radar link to view John. Not the greatest but better than nothing I guess.

Impressive EPAC Hurricane, seems the Atlantic is getting all the bad shear this year.

When one is active, the other is generally fairly quiet.

[Josephine96]

I don't like having a storm this bad with my name.. Prayers for Mexico and extreme southern California..

[Dave C]

Wow Cycloneye, are we on the same wavelength or what!

[cycloneye]

Wow Cycloneye, are we on the same wavelength or what!

Yes at the same time we posted the same. To clarify the radar is from Cuyutlan not from Acalpulco.You can refresh and get the latest image.

[AnnularCane]

john is the one who made it across the pacific right? if so it should have already be retired.

Why is that?

[JonathanBelles]

not many cyclones get across the pacific

[bombarderoazul]

John of 1994 lasted one month as it traveled thousands of miles.

[NetZeroZeus]

Hmm...this doesn't look good for me. It looks like we are for sure going to get at least tropical storm force winds here in Puerto Vallarta, and perhaps 50KT winds, which won't be good for power lines I imagine.
