Super Typhoon Haiyan

Unread post by David »

Super Typhoon Haiyan is just making landfall in the Phillipines. It's strongest winds have been measured at 314 km/h with gusts to 379 km/h. Apparently it it one of the strongest storms ever observed! 8-o

The world's strongest typhoon of the year has slammed into the Philippines. It had been poised to be the strongest tropical cyclone ever recorded at landfall, a weather expert said.

"There will be catastrophic damage," said Jeff Masters, a former hurricane meteorologist who is meteorology director at the private firm Weather Underground.

The US Navy's Joint Typhoon Warning Center in Hawaii shortly before landfall said Typhoon Haiyan's maximum sustained winds were 314 kilometres per hour, with gusts up to 379 kilometres per hour.

"195-mile-per-hour winds, there aren't too many buildings constructed that can withstand that kind of wind," Masters said.

The local weather bureau had a lower reading, saying the storm's speed at landfall had sustained winds at 234 kilometres per hour, with gusts of 275 kph. The bureau takes measures based on longer periods of time.
Thousands of people have evacuated villages in the typhoon's path.

Typhoon Haiyan's speed at landfall was expected to beat out Hurricane Camille, which was 305 kilometres per hour at landfall in the United States 1969, Masters said.

The only tiny bright side is that it's a fast-moving storm, so flooding from heavy rain - which usually causes the most deaths from typhoons in the Philippines - may not be as bad, Masters said.

"The wind damage should be the most extreme in Philippines history," he said.

The storm later will be a threat to both Vietnam and Laos and is likely to be among the top five natural disasters for those two countries, Masters said. The storm is forecast to barrel through the Philippines' central region Friday and Saturday before blowing toward the South China Sea over the weekend, heading toward Vietnam.

The typhoon slammed into the eastern province of Samar. Another province devastated by an earthquake last month was in the path of the storm.

The storm was not expected to directly hit Manila further north. The lowest alert in a four-level typhoon warning system was issued in the flood-prone capital area, meaning it could experience winds of up to 60 kph and rain.
President Benigno Aquino III warned people to leave high-risk areas, including 100 coastal communities where forecasters said the storm surge could reach up to 7 metres. He urged seafarers to stay in port.

Aquino ordered officials to aim for zero casualties, a goal often not met in an archipelago lashed by about 20 tropical storms each year, most of them deadly and destructive. Haiyan is the 24th such storm to hit the Philippines this year.

The president also assured the public of war-like preparations: three C-130 air force cargo planes and 32 military helicopters and planes on standby, along with 20 navy ships.

"No typhoon can bring Filipinos to their knees if we'll be united," he said in a televised address.

Haiyan is a total beast! Josh Morgerman and James Reynolds are in the path at Tacloban City:

6:30 am. Gusts getting violent-- flying tin and branches. Some gusts have an unearthly, feminine howl that gives me the creeps. 974.6 mb and falling. Might be my last update.
Interestingly, PAGASA not as bullish as the JTWC on wind speeds. Have sustained winds of 235 km/h with gusts to 275 km/h.

James Reynolds is the best in the business, would love one day to meet up with him.

Crazy times in the Philippines :/

Storm chasers become rescuers. One injured. My adrenalin increased for awhile ~5mins into the 18min one. Playing beyond wave breaks on surf boards just didnt seem right at the end.

Does this class as our first category 6 off the scale? in terms of peak wind gusts and the shear size of the typhoon?
Gusts to 391kmh is the highest ive heard from this system

Is that 391 estimated or recorded? Would take something decent to withstand and record that wind speed!!

No. You can't really go 'off the scale' of any of the various scales used to measure the highest category of TC's, Hurricanes or Typhoons, because none currently have a maximum limit. So technically, there's no such thing as a Cat 6. :smile:

Haiyan is also by no means the largest TC on record, nor the most intense. Super Typhoon Tip in 1979, which holds both those records, was over twice the size of Haiyan and had a minimum estimated central pressure of 870 hPa, compared to Haiyan's 895 hPa.

Haiyan's estimated maximum 1-minute-wind-speed of 315 km/h (equating to a 10-minute-wind-speed of about 285 km/h) is also just 10 km/h more than those estimated for Super Typhoon Tip, Hurricane Camille in 1969 and Hurricane Allen in 1980.

Typhoon Ida in 1958 and Typhoon Nancy in 1961 were thought to have 1-minute-wind-speeds of about 345 km/h, but speeds prior to satellite technology in 1969 are considered to have been overestimated.

And also during Cyclone Olivia in 1996 a wind gust of 408 km/h was recorded (and confirmed). This is currently the highest non-tornadic wind speed ever recorded. However Olivia was only a Cat 4 cyclone according to it's mean wind speeds.

Yes, Hurricane Hunter aircraft and their dropsondes have encountered tornado-scale mesovortexs embedded in the eyewalls of hurricanes and it's likely that this is what was measured as TC Olivia's eye passed over Barrow Island, Western Australia. Amazing the anemometer withstood those speeds... 8-o


P.S. Don't think the Filipino/Canadian writer of this story will be happy with the editor's headline… :-(

Footage includes two short clips (9:09) from James Reynolds of Earth Uncut TV, showing Josh Morgerman and Mark Thomas rescuing hotel guests from rising waters. Produced with love and sympathy for the Filipino people and the victims of this storm.
Chilling stuff to watch.

The most intense squall I've been in doesn't come close to this. What's more is that this lasted hours and my squall lasted a minute maybe.

Glad I'm not the camerman, but even more glad I'm not the guy who appears at 1:58!

I'm working on ways to make a difference for the likes of Shylyny & Richard's family:
http://tvnz.co.nz/world-news/orphans-in ... rs-5734461

:-k Thoughts?

There family is a lot like mine a couple of years ago, except in our case the parents survived the catastrophe of Feb 22 2011. And so did the son.

As the months go by, recovery is real here. Giving hope as they enter the early days of recovery is possibly more valuable than the practical support.

Would the rain rate at the eye wall be 400mm/h+?

Considering I've recorded 354mm/h instantaneous rain rate and looking at that video (remembering cameras can't pick up rain drops well, so it's even heavier than it looks) it seems that rain is insane. Maybe falling at more like 500mm/h?
