WWW Links for Hurricane Season 2007

The official Utility World Hurricane Frequency List has not been revised yet, but it seems current enough to keep using it for the time being. It lives at:
http://www.ominous-valve.com/hurricne.txt

Users of RSS can subscribe to a truly staggering number of feeds with NOAA weather advisories on anything one would ever want to see. The list is at:
http://www.weather.gov/rss/

As we've seen with Erin, the story isn't always over when NHC stops tracking the remnants of inland storms. The NOAA Hydromet Center usually picks these up when NHC's done. Their advisories are at:
http://www.hpc.ncep.noaa.gov/tropical/tropstorms.shtml

The new Hurricane Hunter WC-130J aircraft continue to undergo enhancements of their real time data transmission capability. As a result, the formats used to return information (and their message headers) have changed for 2007. The full (and highly esoteric) information is at:
http://www.nhc.noaa.gov/scn_2007-07-10.shtml

You might have noticed that the Tropical Cyclone Plan Of the Day (TCPOD) messages posted here are always for the next day. Given the time lag between blog postings and their reading, this is good. However, it means if you didn't see yesterday's, you won't see today's taskings.

For this reason, NOAA posts yesterday's TCPOD at:
http://www.nhc.noaa.gov/text/MIAREPRPD_last.shtml

While the link on the main page of this blog has proven completely reliable for today's TCPOD, another one is at:
http://www.nhc.noaa.gov/text/MIAREPRPD.shtml

For those who really want to know, a rather exhaustive explanation of those cryptic looking weather codes that I wrote when I had a lot more time for this kind of thing is at:

First Hurricane Hunter Comm

From Allan Stern in central Florida:

13927 kHz USB 2027z: USAF MARS Station "Hobby 29" (WC-130J, Keesler AFB), 140 mi NW of San Juan, for phone patch to St Croix Ops for Hurricane Hunter Ops 340/778-0605 ("Croix Ops"); reports 30 min out. (16Aug2007) (ALS).


It appears that airplanes are being flown to temporary homeplates closer to the storm. At least, this would explain why the generic Keesler HOBBY callsign was being used instead of TEAL. It'll be interesting to hear what the actual missions ID as.

"Hurricane Hunter" flights (USAF Reserve 53rd WRS, WC-130J) do not do anywhere near as much HF as they used to when Miami Monitor was still on-air from the National Hurricane Center. There is some spotty use of HF-GCS. Otherwise 13927.0 kHz USB, the MARS phone patch channel, is one of the best places to snag these.

[UPDATE 17/1920 UTC: It was indeed a ferry flight, moving the WC-130Js to a closer-in airfield. Confirmation at the Caribbean Hurricane Net site.]

Amateur Hurricane Watch Net Activates

The Hurricane Watch Net has activated on 14325 kHz USB as Dean nears the Lesser Antilles. The purpose of this net is to relay weather observations to the National Hurricane Center (NHC) in Miami, FL, and to disseminate the latest NHC advisories to anyone needing them.

In a procedure that may be new for some people, HWN is now advising listeners to monitor the Maritime Mobile Service Net frequency of 14300 kHz USB for information and HWN activation notices. A weak station was active on this frequency at 16/2317 UTC reading a hurricane advisory, and then taking a standby for vessels.

This net has a web site at http://www.hwn.org/ .

The official Utility World Hurricane Frequency List is here.

Dean Is Getting Nasty

Hang on, this is a big one:

HURRICANE DEAN DISCUSSION NUMBER 13
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL042007
1100 AM EDT THU AUG 16 2007

DEAN IS CONTINUING TO INTENSIFY. THE HURRICANE HAS DEVELOPED A SMALL
CLOUD-FILLED EYE THIS MORNING ON VISIBLE SATELLITE IMAGES AND THE
CIRRUS OUTFLOW IS EXPANDING IN ALL QUADRANTS. SUBJECTIVE DVORAK
ESTIMATES FROM TAFB/SAB ARE 77 KT...WHILE OBJECTIVE ESTIMATES ARE
HIGHER. THE INITIAL INTENSITY IS RAISED TO 80 KT. AN AIR FORCE
RESERVE HURRICANE HUNTER WILL BE IN THE EYE OF DEAN LATER TODAY TO
OBTAIN A BETTER ESTIMATE OF THE INTENSITY. WIND AND MAXIMUM SEAS
DATA FROM NOAA BUOY 41010 WERE CRITICAL FOR THIS ADVISORY.

THE INITIAL MOTION IS 280/21. THERE IS LITTLE CHANGE TO THE
PREVIOUS FORECAST REASONING. A STRONG DEEP-LAYERED RIDGE SHOULD
CONTROL DEAN'S MOVEMENT DURING THE NEXT FEW DAYS. THIS RIDGE SHOULD
FORCE THE HURRICANE ON A SPEEDY WESTWARD TRACK THROUGH THE CENTRAL
CARIBBEAN SEA. MODEL GUIDANCE IS IN CLOSE AGREEMENT ON THE TRACK
THROUGH ABOUT 3 DAYS. THEREAFTER...AS THE HURRICANE APPROACHES THE
NORTHWESTERN CARIBBEAN SEA...MOST OF THE GUIDANCE SUGGESTS THAT
DEAN WILL REACH THE WESTERN PERIPHERY OF THE SUBTROPICAL RIDGE AND
ATTEMPT TO MOVE MORE TO THE WEST-NORTHWEST. GUIDANCE IS IN GOOD
AGREEMENT ON THIS SCENARIO AS WELL...EXCEPT FOR THE GFDL. IT IS
STALLING A MIDDLE-LEVEL LOW...CURRENTLY OVER THE BAHAMAS...IN THE
EASTERN GULF OF MEXICO. THIS SOLUTION ALLOWS THE HURRICANE TO MOVE
MORE TO THE NORTHWEST INTO THE CENTRAL GULF OF MEXICO. THIS
SOLUTION IS CONSIDERED AN OUTLIER AT THIS TIME. HOWEVER...THE
OFFICIAL FORECAST IS NUDGED A LITTLE TO THE NORTH AT 120 HR IN
DEFERENCE TO THE GFDL FORECAST.

ALL GLOBAL MODELS ARE DEVELOPING A LARGE 200 MB ANTICYCLONE AROUND
DEAN DURING THE NEXT FEW DAYS. IN COMBINATION WITH THE DEEP WARM
WATER OF THE CARIBBEAN SEA...DEAN IS LIKELY TO BECOME A MAJOR
HURRICANE IN THE EASTERN CARIBBEAN SEA. THE OFFICIAL FORECAST USES
A BLEND OF THE SHIPS...LGEM...AND GFDL MODELS...WHICH DEVELOP THIS
SYSTEM INTO AN EXTREMELY DANGEROUS CATEGORY 4 HURRICANE BY THE TIME
IT REACHES THE NORTHWESTERN CARIBBEAN SEA.

THE NOAA GULFSTREAM-IV WILL CONDUCT A SYNOPTIC SURVEILLANCE MISSION
FOR THE 17/00Z NUMERICAL GUIDANCE.

Flossie Disappears, Hurricane Hunter Flight Cancelled

Flossie just vanished in colder water, largely sparing the Big Island.

Dean is cranking up on a track that usually spells trouble this time of year, and may become a Category 3.

NASA ANNOUNCES WEB COVERAGE OF NEXT SPACE SHUTTLE MISSION

CAPE CANAVERAL, Fla. - A prelaunch webcast, live blogs, podcasts, pictures and videos highlight NASA's Web coverage of space shuttle Endeavour's STS-118 mission to the International Space Station. NASA will provide continuous online updates at:

http://www.nasa.gov/shuttle

A live webcast featuring STS-116 astronaut Joan Higginbotham will start the in-depth coverage of the mission at 11:30 a.m. EDT on Aug. 7.

A blog will update the countdown beginning about six hours before Endeavour is scheduled to lift off on Aug. 8 at 6:36 p.m. EDT. Originating from NASA's Kennedy Space Center, the blog is the definitive Internet source for information leading up to launch.

During the 11-day mission, Endeavour's crew of seven astronauts will add a segment to the right side of the station's backbone, or truss, deliver 5,000 pounds of supplies and conduct at least three spacewalks to install the new components and to replace one of the station's attitude control gyroscopes. Visitors to NASA's shuttle Web site can read about the crew's progress and watch the spacewalks live from the space station.

As Endeavour's flight wraps up, NASA will offer a blog detailing the spacecraft's return to Earth.

Two Earthquakes In North Pacific, With Small Tsunami

A second large Pacific Ocean earthquake occurred in the Aleutians at 0322 UTC, magnitude 6.9, and a third near Sakhalin Island at 0238 UTC, magnitude 6.4.

The Sakhalin Island event, while comparatively small, has resulted in the Japan Meteorological Agency issuing a "Tsunami Attention" bulletin for the west coast of Hokkaido. A small tsunami of 30 centimeters was measured in Hokkaido, and more on a similar scale are possible. These are way too small to cause the kind of damage associated with Thailand a couple of years back.

The Sakhalin earthquake itself has caused at least one fatality on the island, which is off Russia.

Vanuatu Earthquake 1708 UTC

The following is a release by the United States Geological Survey, National Earthquake Information Center: An earthquake occurred about 45 km (30 mi) east-southeast of Luganville, Espiritu Santo, Vanuatu at 11:08 AM MDT, Aug 1, 2007 (Aug 02 at 4:08 AM local time in Vanuatu). The magnitude and location may be revised when additional data and further analysis results are available. No reports of damage or casualties have been received at this time; however, this earthquake may have caused damage due to its location and size.

The earthquake locations and magnitudes cited in these bulletins are very preliminary, and may disagree with the more accurate USGS locations and magnitudes computed using more extensive data sets.


No tsunami warnings have been issued at this time.

If the preliminary depth measurements hold up, this would be an extremely deep earthquake, which often means less damage than an event of this size near the surface.

Interesting German 27 MHz Allocations

Tom, DL8AAM, posted a message to UDXF, containing, among other things, this allocation of the 11 meter band for Germany. The 11-meter situation is similar in a lot of countries, and it's a good demonstration of the pressures on all utility radio spectrum above maybe 25 MHz. Note the international vs local (more detailed) spectrum uses, plus the many overlapping subbands and shared ranges:

26175-27500
Mobile (Maritime)

UK Flood Activity

Peter Thompson and other listeners on the UDXF list have heard HF transmissions from rescue helicopters working the floods in England. Callsigns are the usual "RESCUE" plus a number. They are working Kinloss Rescue.

News broadcasts continue to show helicopter rescues in the UK, so I would imagine the activity is ongoing.

Another UDXF user named "Paul" passes along this freq list for Kinloss Rescue (all USB):

2182 Distress
3023 Night (pri)
3089 Night (sec)
5680 Day (Pri)
5699 Day (sec)
6760 Discrete
8980 Discrete
9001 Discrete

4706 kHz USB has also been reported, by "David" on UDXF, who adds that 6736 (day) and 4718 (night) are also known USB backup frequencies.

More Long EAMs

Jeff Haverlah continues to monitor long Emergency Action Message transmissions on the US Air Force High-Frequency Global Communications System.

On July 22, the hour/half hour restoral EAM from McClellan Global consisted of two messages of 52 characters each.

At 1721 UTC, Andrews broadcast the longest EAM yet - 287 characters! It had the distinctive repeating formating and the typical 14-character ending block. Unlike the usual Saturday activity, this was on a Sunday, and not by a Nightwatch player using a tactical callsign.

I wonder how long THAT one took to transmit, in the slow US Air Force drawl.

[UPDATE 03 AUG: Sometime in July, Tom Sevart heard Andrews with 270 characters at 1800.]

Large Joint Exercise Begins Today, Off US East Coast

Named "Bold Step 2007," the Joint Task Force Exercise, or JTFEX, will involve some 15,000 personnel from the U.S. and British navies.

Participating units:

USN Harry S. Truman Carrier Strike Group
USN Dwight D. Eisenhower Carrier Strike Group
Royal Navy Carrier HMS Illustrious
Royal Navy Destroyer HMS Manchester
USN attack submarine USS Boise
USN attack submarine USS Montpelier

The exercise begins July 26, and lasts 5 days.

Long Saturday EAMs Continue in July

As if we needed any further proof that long Emergency Action Messages on UTC Saturdays are nothing remarkable, we got another one in July. Jeff Haverlah again:

1823z 14 Jul 07

11175.0 was active at 1758z+/- with unknown HFGCS station (too
weak/"muddy" to id) with a 200-character count ± EAM (M4GSLB maybe; missed the number in the mud but sounded like ? zero zero; and, it was long enough for it) containing distinctive repetitive formatting and apparently ending in the common 14-character ending block. Typical Saturday activity.


You have that right, Jeff.

Log Extract: Long EAMs Are Not Remarkable

As I suspected, previous reports published in our Utility Logs column have indeed shown Emergency Action Messages (EAMs) that were as long as, or longer than, the 174-character one of June 26 that has aroused attention. Recall from my previous blog entry that this EAM has been cited by unknown Internet sources as the longest since the first Persian Gulf War.

It isn't.

This would tend to reinforce the argument made by a writer to Bill Gertz's column, who was quoted in the same post, that long EAMs generated by periodic exercises "should not be considered unusual."


Long EAM Examples:

Jeff Haverlah, a long-time Utility Logs contributor and generally Mr. EAM in this hobby, reported the following on February 17, 2007:

1729z 17 Feb 07

11175.0 was active at 1431z with OFFUTT bcsting a 248-character
EAM (TOXRB7) containing common, repetitive, distinctive formatting,
including the 14-character ending block common to these strings.

11175.0 was active at 1717z with OFFUTT bcsting a 163-character
EAM
(TO57UN) containing distinctive (but not apparently repeating)
formatting including the 14-character ending block common to these
strings.


(Emphasis mine, for readability.)

Also from Jeff, this report of March 10:

0039z 11 Mar 07

11175.0 was active at 101722z+/- with OFFUTT (weak with deep
fading) bcsting a 201-character EAM (TOCDIJ) containing distinctive formatting and ending in a common 14-character ending block.


And, on 26 May, again from Jeff:

1555z 26 May 07

11175.0 was active at 1447z with ANDREWS (good levels here)
bcsting a 202-character EAM (IV3PR6) containing distinctive repetitive formatting (but did not end in the 14-character ending block common to these strings.) Activity common to utc Saturday's (1447z 28 Apr 07 245-character IVLZ7S) for example.) All Andrews xmsns are keying off with a soft pop/thump.


And, on June 23 near the beginning of the June 25 period in question, from Jeff:

1434z 23 Jun 07

8992.0 was active at 1418z with ANDREWS (good/fair levels here)
bcsting a 121-character EAM (IVSAD2) containing distinctive, repetitive formatting.


Conclusion:

It seems significant that all of these long messages appeared at roughly one-month intervals, and on UTC Saturdays. There is a suggestion here of a monthly activity (likely a communications exercise) that generates long EAMs. We can therefore conclude that, while the June 25 activity was noteworthy for call signs, traffic volume, and a special test string, it was very much not noteworthy for EAM length. The writer to the Inside the Ring column appears correct.
