SPAC: PAM - Post-Tropical

[talkon]

@xtyphooncyclonex

That 942.1 mb is not from iCyclone members, it is official data from Australia BoM at http://www.bom.gov.au/cosppac/rtdd/q1c7o0hj48yu/

[xtyphooncyclonex]

It is ALSO from the iCyclone members from Vanuatu. Probably they measured at the same spot....

Current location of Pam...Just east of Port Villa...which probrably escaped the eyewall...Not so much eastern Efate...

[xtyphooncyclonex]

I don't get why the station says only 50 knot gusts. I experienced it and blew off some branches.

People in Vanuatu are reporting turbulent and violent conditions

No doubt, violent winds are still raking the island at this very moment. Anyhow... Sorry this post is so weather-nerdy-- we know a lot of y'all are worried about family and friends. Communications are spotty. If you're on Efate and still able to, please let us know how you're doing and what you're seeing and hearing!

11:25 pm Friday (Vanuatu): The eye of Cyclone PAM has veered a tad E and seems to be skimming along the E side of Efate. Reports from Port Vila are frightening, and we have several brave iCyclone members who are posting to this page as they huddle in bathrooms and safe rooms. A member in Port Vila reported 944.6 mb and turbulent, shifting winds at about 11:10 pm VUT-- I'm trying to find out more about this reading, as we have so little other data to work with. To folks on Efate who are still with us: HANG IN THERE. We're all with you in spirit. Warm Southern Californian hugs for all of you.

BTW, iCyclone member in Port Vila reported 937.9 mb around 11:55 pm, but we've been unable to find out much about that reading.

Thus making the 938 mbar pressure more impressive.

Interesting fact...Pam is the first category 5 to make landfall since Super Typhoon Haiyan in November 2013...

Although Typhoon Rammasun back in July 2014 argues against that which was rated as a strong category 4 135 knots before landfall over Hainan Island but had a reading of 892.3 mb by a personal station which is Wilma type...Muchy stronger...

Best track for 2014 isn't out yet...

From Weather Underground:

One satellite estimate from the University of Wisconsin suggested Pam's central pressure may be as low as 890 millibars. Another estimate Friday morning, U.S. time had a lower pressure (879 millibars). The lower the central pressure, the stronger the tropical cyclone, in general.

What?

Port Villa was so near the eyewall yet according to Masters, they only received 31 mph gusting to 59?

Are there some mountains protecting this capital?

Aren't you reading the posts of iCyclone and my posts about their conditions? The winds by Masters have no specified time and that you should read MORE before you judge

What time? Hard to believe. I think the anometer is not working.

Maybe I had to repost my friendly warning.

This is a very serious situation going on in those islands so we don't need bickering going on between members.You can have differences of opinion but do it with respect to others that may not agree with your point of view. Thank you for your cooperation.

I saw some gusts near hurricane force in Port Vila, with sustained between 50 and 60 mph at peak

Given that people very rarely experience those winds, winds of that level would accurately describe the conditions reported by the people

[CrazyC83]

If the Schloemer equation was used based on the 938mb pressure, about 30 nautical miles from the center (with an RMW of 35 nautical miles used and an outermost closed isobar of 1012mb):

(PR - Po) / (Pn - Po) = e^(-RMW/R)

(938 - Po) / (1012 - Po) = e^(-35/30) = e^(-0.8333) = 0.3114

That calculates out to a pressure around 904mb at that time. If a smaller RMW was used, the pressure would be lower.

First daylight image in Tarawa shows flooding but at least in this area the wind was not too strong.Hopefully no lose of life occurred.

[CrazyC83]

At Tafea landfall, I would estimate the intensity at 150 kt, which I think is the peak intensity as well.

44 dead so far.RIP their souls.

There are unconfirmed reports that 44 people had died in Penama province in the north-east of Vanuata, the UNOCHA said in a statement on Friday, according to Reuters.

There have been unconfirmed reports of deaths in Vanuatu after tropical cyclone Pam turned towards the capital, making landfall overnight.

The category five storm, with winds over 250 km/h, made a direct hit on several small islands and the eye passed over the eastern side of Efate island, home to capital city Port Vila.

It appears communications are down and there's fears for the 250,000 residents of Vanuatu, many of whom live in basic structures.

Sune Gudnitz from the United Nations office for the Co-ordination of Humanitarian Affairs warns it appears to be a "worst case scenario" for the island nation after the storm took a turn towards the southern islands.

He told the ABC that very few structures would be able to withstand the category five cyclone and they were expecting the total destruction of many buildings and homes.

The Vanuatu National Disaster office says red alerts are in place for Torba, Sanma, Penama, Malampa, Shefa and Tafea provinces.

Heavy to torrential rainfalls and flooding, including flash flooding are expected over low lying areas. Landslides are also expected.

All Vanuatu airports remain closed. ONE News understands there are plans to send aid flights in tomorrow.

SE eyewall crossing Tanna Island now. Doesn't look to have weakened much at all.

[Alyono]

unconfirmed reports of deaths. Lets wait for more info

[1900hurricane]

I believe that 135 kt is the highest winds ever assigned to a storm by Nadi. After a quick check on Wiki, Zoe was the previous highest with 130 kt.

So sad to see that deaths occured...Vanuatu is home to some of the friendliest people on earth!
