The Eastern Pacific's Hurricane Barbara is still alive as a tropical depression at the edge of the Atlantic's Gulf of Mexico, and has the potential to gain new life as an Atlantic tropical cyclone later today. Barbara made landfall near 4 pm EDT (1 pm PDT) May 29, 2013, on Mexico's Bay of Tehuantepec coast, as a Category 1 hurricane with 75 mph winds. The storm killed two people, and brought heavy rains of 16.02" (407mm) to Arriaga in the state of Chiapas in an 18-hour period. Barbara remains a serious rainfall threat today. The storm intensified remarkably rapidly, becoming a hurricane just 21 hours after it became a tropical depression. According to NOAA's Historical Hurricane Tracks website, only one other Eastern Pacific hurricane has ever made landfall in May--Category 1 Hurricane Agatha of 1971, which hit Mexico west of Acapulco. Barbara is just the 2nd hurricane ever to make landfall in the Bay of Tehuantepec (the other: Category 1 Hurricane Rick of 1997.) Barbara's formation date of May 28 was the 2nd earliest appearance of the Eastern Pacific's 2nd named storm of the year; the record earliest second storm of the year occurred just last year, on May 21, 2012 (Tropical Storm Bud.) The average date for the formation of the Eastern Pacific's 2nd storm is June 25. Barbara's landfall location was the most easterly on record for an East Pacific hurricane. Records of Eastern Pacific hurricanes go back to 1949, but aren't really reliable until 1966.

Barbara survived its overnight crossing of Mexico's Isthmus of Tehuantepec with its circulation intact, but lost nearly all of its heavy thunderstorm activity. This morning, the center of Barbara was located just inland from the southernmost waters of the Gulf of Mexico's Bay of Campeche. Barbara was drifting northwest, towards open water, at 3 mph. With wind shear a moderate 10 - 20 knots over Barbara, the storm has the potential to be classified as an Atlantic tropical depression later today if its center emerges over water. However, latest satellite loops have shown a steady reduction in the storm's heavy thunderstorms this morning, and Barbara may lose its circulation before it has time take advantage of the Gulf of Mexico's warm waters. Since Barbara is a small storm, the moderate wind shear may be too great for it to withstand. None of the reliable computer models predict that Barbara will survive into Friday. If Barbara is able to re-intensify to a tropical storm, it would keep the name Barbara, becoming the first Atlantic storm ever to have an Eastern Pacific name. Formerly, Eastern Pacific storms crossing into the Atlantic would be given a new name, but a recent NHC policy change allows storms to keep their names when they cross from one ocean basin to another. If Barbara were to dissipate before reaching the Gulf, then its remnants regenerate into a tropical storm in the Gulf, it would be named Andrea. If you want to discuss this year's hurricane season via Twitter, AP will be doing a hurricane twitter chat today (Thursday) at 1 p.m. EDT: #APStormChat; the National Hurricane Center is doing a hurricane chat at 2 pm EDT: #HurriChat.

Double ocean tropical cyclones: a rare breed
According to the Hurricane FAQ, since 1923 there have been four East Pacific tropical storms or hurricanes that have maintained their circulations while crossing into the Atlantic Ocean, becoming tropical storms in the Atlantic Ocean:

Northeast Pacific Tropical Storm Alma (May 2008) became a remnant low in the Atlantic, where it merged with another tropical wave which generated Atlantic Tropical Storm Arthur. Arthur hit Belize as a tropical storm, killing nine and doing $78 million in damage.

Northeast Pacific Hurricane Cosme became Atlantic Tropical Storm Allison in June 1989. Allison hit Texas as a tropical storm, and heavy rains from Allison--up to 30" in some regions of Texas and Louisiana--triggered floods that killed eleven people and did $1 billion in damage. (A later incarnation of Tropical Storm Allison in 2001 also hit Texas, and caused such extensive flooding that its name was retired.)

An unnamed Northeast Pacific Tropical Storm (September-October 1949) became Atlantic Hurricane (Storm #10) and hit Freeport, Texas as a Category 4 hurricane, killing two people.

An unnamed Northeast Pacific Tropical Storm (October 1923) became Atlantic Hurricane (Storm #6) and made landfall as a Category 1 hurricane in Louisiana.

There have been eight Atlantic tropical storms or hurricanes that have maintained their circulations while crossing into the East Pacific Ocean, and were then tropical storms in that ocean.


Figure 2. Severe weather outlook for Thursday, May 30, calls for a "Slight Risk" of severe weather over much of the Midwest. You can follow today's severe weather outbreak from our Severe Weather page.

Multi-day severe weather outbreak in the Midwest brings more tornadoes and flooding
It was an active day for tornadoes in the Midwest on Wednesday, with NOAA's Storm Prediction Center (SPC) logging 23 preliminary tornado reports. Twisters touched down in Nebraska, Kansas, Texas, Oklahoma, Iowa, and Wisconsin. The tornadoes missed heavily populated areas, and no injuries and only minor damage was reported. The latest forecast from NOAA's Storm Prediction Center call for a "Moderate Risk" of severe weather today (Thursday) over much of Oklahoma, with the potential for several strong EF-2 and EF-3 tornadoes.

As discussed by wunderground's weather historian Christopher C. Burt in his latest post, Some Phenomenal Rainfalls the Past Week in the U.S., the country has seen a lot of very heavy rainfall over the past week that has caused serious flooding. Of particular concern is Iowa, where Governor Terry Branstad issued a disaster proclamation on Tuesday for 13 Iowa counties, due to recent storms and flooding.The Iowa State Climatologist, Harry Hillaker, announced on May 29th that this has been the wettest spring (March-May) on record for the state since records began 141 years ago. A state average of 16.4” has been preliminarily reported. The previous wettest spring was 15.5” way back in 1892. He warned that “Iowa is at a tipping point for a major flood event”. Rains of 1 - 2" are expected over Eastern Iowa the remainder of the this week, which will keep most rivers above flood stage. Another round of rains of 1 - 2" are likely on Tuesday and Wednesday of next week, when the next storm system rolls through. That system also has the potential to bring a severe weather outbreak to the Midwest.

Chinese Physicists Smash Distance Record For Teleportation

The ability to teleport photons through 100 kilometres of free space opens the way for satellite-based quantum communications, say researchers

Teleportation is the extraordinary ability to transfer objects from one location to another without travelling through the intervening space.

The idea is not that the physical object is teleported but the information that describes it. This can then be applied to a similar object in a new location which effectively takes on the new identity.

And it is by no means science fiction. Physicists have been teleporting photons since 1997 and the technique is now standard in optics laboratories all over the world.

The phenomenon that makes this possible is known as quantum entanglement, the deep and mysterious link that occurs when two quantum objects share the same existence and yet are separated in space.

Teleportation turns out to be extremely useful. Because teleported information does not travel through the intervening space, it cannot be secretly accessed by an eavesdropper.

For that reason, teleportation is the enabling technology behind quantum cryptography, a way of sending information with close-to-perfect secrecy.

Unfortunately, entangled photons are fragile objects. They cannot travel further than a kilometre or so down optical fibres because the photons end up interacting with the glass breaking the entanglement. That severely limits quantum cryptography’s usefulness.

However, physicists have had more success teleporting photons through the atmosphere. In 2010, a Chinese team announced that it had teleported single photons over a distance of 16 kilometres. Handy but not exactly Earth-shattering.

Now the same team says it has smashed this record. Juan Yin at the University of Science and Technology of China in Shanghai, and a bunch of mates say they have teleported entangled photons over a distance of 97 kilometres across a lake in China.

That’s an impressive feat for several reasons. The trick these guys have perfected is to find a way to use a 1.3 Watt laser and some fancy optics to beam the light and receive it.

Inevitably photons get lost and entanglement is destroyed in such a process. Imperfections in the optics and air turbulence account for some of these losses but the biggest problem is beam widening (they did the experiment at an altitude of about 4000 metres). Since the beam spreads out as it travels, many of the photons simply miss the target altogether.

So the most important advance these guys have made is to develop a steering mechanism using a guide laser that keeps the beam precisely on target. As a result, they were able to teleport more than 1100 photons in 4 hours over a distance of 97 kilometres.

That’s interesting because it’s the same channel attenuation that you’d have to cope with when beaming photons to a satellite with, say, 20 centimetre optics orbiting at about 500 kilometres. “The successful quantum teleportation over such channel losses in combination with our high-frequency and high-accuracy [aiming] technique show the feasibility of satellite-based ultra-long-distance quantum teleportation,” say Juan and co.

So these guys clearly have their eye on the possibility of satellite-based quantum cryptography which would provide ultra secure communications around the world. That’s in stark contrast to the few kilometres that are possible with commercial quantum cryptography gear.

Of course, data rates are likely to be slow and the rapidly emerging technology of quantum repeaters will extend the reach of ground-based quantum cryptography so that it could reach around the world, in principle at least.

But a perfect, satellite-based security system might be a useful piece of kit to have on the roof of an embassy or distributed among the armed forces.

Something for western security experts to think about.

It is what it is, to use a cliche'.

Hopefully this is a non Florida event Hurricane season. Then I hope it is a non-popluated area event ATLANTIC hurricane season.

Unfortunately, it has already been a 'bad' epac season.

This is why we blog and follow things here.

Besides Barbara, Alvin didnt do much

The storm might hit norman, all though I hope and think not


Well, it's on a direct path for Norman for now.

Cell going for Norman should be tornado warned. Rotation is noticeable on RadarScope (not so well on GRLevel3) and it's increasing. However, the storm MIGHT go south of Norman but we'll see.

Tornadoes to the north and south, circulation to watch to the southwest (the Cashion one has the best chance to impact my area - but it is not doing well at the moment).

Well, I'm off - gotta be somewhere. Hopefully, things will calm down here - I mean OK, not necessarily the blog :P.

some weak thunderstorms are starting to fire up,but the worst of it is further south and west. More likely to have problems closer to dinnertime.
