The Storm Before the Calm

Hurricane Florence is going west–no, south–no, east-notheast, no—hell, nobody knows.

So, as things develop, all of the usual suspects (cue Casablanca–roll film) are behaving in the the way that all the usual suspects do:

  • Some television meteorologists are standing in knee deep water or out in the wind.
  • Other television meteorologists are predicting where the storm will go based on satellite fed, computer generated wild–ass guesses.
  • Elected officials are assuring people that: a) everything will be fine, or b) mandatory evacuation is necessary (“Abandon your posts! Run for your lives!” Denethor, Return of the King). [Flip coin here]

I’ll keep you posted.

 

 

Whatever Shall Be Will Be

Hurricane Florence is getting closer. The eye of the hurricane will be about 250 miles to the south of where I live, but, it’s not the eye that causes problems.

Hurricanes–cyclones–rotate in a counterclockwise direction. (Cyclonic means counterclockwise.) This means that if one’s location is above the eye, the hurricane is going to push the water in (deja vu–didn’t I say this yesterday????). So being above the eye is not necessarily a good thing.

Florence is now a category 4 hurricane, which means it moves faster and inevitably covers more territory. It may become a category 5. In any case, I’m going to get wet.

My wife, being much smarter than me, is taking our children to safety, far west and uphill from here. After all our years together, she knows that I live to help, so she understands (but does not necessarily give explicit approval) to my plan to stay here and provide emergency communications.

I expect to be successful, but this could be my last rodeo. After this, I may have to hang up the emergency communications hat and satisfy myself with the more sedate aspects of amateur radio; maybe I’ll take an occasional cruise, or whatever.

Actually, I look forward to that.

Major League catchers eventually succumb to their knees. Superstar quarterbacks succumb to traumatic brain injury. I suspect that, after this storm, I’ll succumb to whatever affliction affects disaster junkies.

Maybe I’m due to have some fun instead of a having one more additional fulltime job.

What do you think?

Pick at the Peak of Ripeness!

September is when the hurricanes off the east coast of North America become ripe enough to be harvested and truly enjoyed. Like grapes or tomatoes, there are a few outliers that ripen earlier, but also like tomatoes and grapes, early hurricanes lack that full-bodied flavor that literally knocks you off your feet–sometimes permanently. Like tomatoes, hurricanes are best when picked fresh off the vine and tasted immediately.

If you don’t live in an area that experiences hurricanes, it is difficult to truly share the experience, but, I shall try. First, although the wind looks impressive on television, it is the storm surge of water that kills the most people. In Virginia, where we have been assured that there is no climate change, the sea levels have inexplicably risen and the land has subsided–a fancy word for “sunk.” The land sinks because industries such as paper mills pump so much water out of wells that the land actually sinks.

Evacuation is an option, but if you are not on the road at least three days before a hurricane makes landfall–with a confirmed reservation at a hotel well inland–you are going to bounce around in your car stuck in a 200 mile traffic jam in high winds heavy rains, and other cars tunning out of gas.

As the storm approaches, the water comes into the rivers and tributaries at high tide, the wind tends keep the water trapped inland, so the next few high tides keep adding. Then, there’s the rainfall. Yesterday–long before the hurricane is due, we got between 3 – 5 inches of rain. Since the most important thing around here is real estate development, all the low-lying wooded areas have been elevated so that instead of the water flowing into those areas, it flows the other way, into mature neighborhoods. Since electricity is also lost early in the game, the sewage treatment pumping stations fail; the water flowing through the streets tends to exhibit wads of toilet paper and worse.

The loss of electricity also means, given that there was never any global warning, everybody gets to enjoy the 90+ degree temperatures and 80+ percent humidity sans air-conditioning. Plus, ATMs, gas pumps, cash registers, etc. don’t work without electricity, so forget your debit or credit card. It’s exact change, cash only.

Afterward, the streets are lined with soggy wallboard and furniture from houses that were flooded. These sit, bake in the sun, grow mould, get rained on, wash the mould into the watershed, repeat. But, hey, Katrina barely bothered Louisiana and Maria was no problem for Puerto Rico, so what, me worry

It’s not a complete picture of what you may be missing, but hopefully it will help you share in our experience.

 

Mother Nature and the Odds

I live in an area that has experienced hurricanes, but not since 2011. Some around here now feel that we’re free of that threat. There might be some truth, at least for a while, given that current weather trends tend to have wind shear that trim the tops of hurricanes, weakening them, and there is a natural pattern that tends to push the storms back out into the Atlantic.

We’re good, right? After all, once a weather pattern occurs, it doesn’t change—does it?

Long ago, in statistics class I was taught an interesting fact. You flip an honest coin 100 times, and it comes up heads each time. What are the odds it will come up heads on the next flip?

Fifty-fifty.

We’ve blamed el Nino, la Nina, butterflies in Africa, etc. I don’t think we’ve quite figured anything out.

Disaster Communications

This past weekend, amateur (ham) radio operators in the Western Hemisphere participated in an annual emergency exercise called Field Day. In the event of a disaster, regular communications is often disrupted. Not only can cellular equipment be damaged, but the system can be overloaded by increased usage; in some cases, cellular communications can be limited to essential personnel ONLY by FEMA.
Most home telephones (for those who still have them) are not independent circuits, but are part of the house’s internet/cable television system. If power is lost, anyone with a wireless telephone won’t be able to use it.
Handling short range communications via amateur radio is relatively easy. Field Day is to practice as to how long range communications can be ensured without relying on existing systems. Our local club set up seven radio stations at a local park; antennas designed for the various operating frequencies were strung from trees, with the highest being at least 60 feet off the ground. The radios—along with computers, and the all-important coffee maker—were powered by solar cells or generators.
The actual communications portion of Field Day began at 2:00 PM on Saturday and continued around the clock. During that time, over 700 other stations were contacted; most were other stations set up for the drill, but there were amateur operators from around the world that made contact with us as well.
Most of us hope never to have a fire, but we have smoke alarms, fire extinguishers, and fire insurance. The few of us that do have a fire are relieved to have the additional protection. The same holds true for amateur radio’s role in communications. It’s not needed every day, but when it is needed, it can be a life saver.
The best part? Hams often arrive with their own equipment and provide the service at for free. THAT is the reason it’s called the Amateur Radio Service; hams cannot be paid for the services they provide.

The (Hurricane Sandy) Saga Continues

So far, Hurricane Sandy appears to be headed north of us. Of course, that’s the actual center of the storm – the southern part of the storm that we may experience is still within the system and will manifest itself primarily as wind and rain.

The biggest problem may be at high tide tomorrow. The tide goes in. The tide goes out. Except when it doesn’t.

WTKR Weather Coverage

At times like this, the tide comes in and the wind keeps it in. Then the next high tide comes along and pushes more water in. That’s when the street looks like a small river – which will probably happen tomorrow morning around 9:42 or so, when high tide occurs.

The other big issue is that as the wind hits, trees with leaves are more affected by the wind than trees without leaves. The trees still have lots of leaves. Trees falling over in and of themselves are not a big deal, but they do have a nasty habit of toppling power lines and blocking roads.

So the bottom line is that of the many things that may happen…

…at any minute…

…because this is a tense situation…

…so take cover…

Very little has happened so far.

But you never know.
