Fire season

Saturday, July 30th, 2005

No matter what the winter was like, dry and cold, or wet and warm (like last winter), local CDF always claims that the next fire season could be one of the worst ever.

If you live in or adjacent to a wild land as we do, fire is always a concern. I’ve listened to the local fire departments for years on a varying array of scanners, especially during fire season. A few years ago I set up a ShoutCast server to broadcast my scanner onto the net so I could monitor it from work.

This year I redid the service as a Windows Media Encoder. There’s a link available on the SLOWeather links page. At this time, it will support up to 5 concurrent listeners. I can bump that up if it becomes popular.

Right now, there are 2 channels mixed on the server, SLO County fire, and CDF local.

StrikeStar lightning

Friday, July 29th, 2005

The SLOWeather lightning tracker is now a part of the StrikeStar lightning triangulation network. You can see the maps for the US on the StrikeStar website.

StormVue on line

Thursday, July 28th, 2005

StormVue is Astrogenic’s Java interface to their NexStorm software, and lets you, the site viewer get minute by minute updates of lightning activity, control the zoom level, and even time-loop the display. The SLOWeather StormVue is now on-line here.

Try it out, if you like. And as always, feedback is welcome.

Lightning page now has a map

Wednesday, July 27th, 2005

If you’ve checked the lightning tracker since mid afternoon Wednesday, you’ve seen the map arrived and is on-line. It looks like the tracker is working pretty well. There was a cell near Daggett shown on the Intellicast radar in about the same location as the tracker was showing a lot of strikes. The software even put up a circle indicating a storm for a few minutes.

I’m amazed at how well a single antenna lightning tracker can work. The commercial sites like USPLN and Vaisala use multiple detectors to triagulate lightning strikes.

There is at least one private initiative to tringulate lightning strike data over the Internet. More on that later.

SLOWeather Lightning page back!

Tuesday, July 26th, 2005

After an absence of almost a year, the SLOWeather lightning tracker is back on line with a new Boltek PCI card, and a new version of the Astrogenic NexStorm software.

Both were purchased from Ambient, makers of the Virtual Weather Station programthat creates the graphics for the weather pages.

I have the range cranked up and the squelch cranked down to show almost anything the antenna hears. The update period is also very short, while the strike persistency is set to 3 hours so I don’t have to check it that often.

We’re also waiting on delevery of the background maps, so all the display shows right now are range rings and azimuth lines.

As soon as we get a verifiable storm I’ll be checking the antenna orientation for accuracy, too.

Favorite Forecast?

Sunday, July 24th, 2005

What’s your favorite source for weather forecasts on the Internet? Most sites seem to simply repackage the National Weather Service (NWS) forecasts. AccuWeather and The Weather Channel have their own meteorologists to make their own predictions. Maybe Intellicast does as well. There are links to the SLO forecast for all 4 of these on the current SLOWeather home page.

Some comments about the NWS. Our forecasts come out of the Oxnard office, so, even though we are at the northern limit of their forecast area, I think we get better service from them. And they have some other cool products that the other sites don’t have, like the 3 hour lightning probability, and the graphic precip forecast. And I like reading the NWS Forecast discussion, too.

SLOWeather visitors

Saturday, July 23rd, 2005

I’m in the process of redesigning the SLOWeather pages. A few days ago I added a Statcounter to the home page. It collects an interesting array of information about the visitors to SLOWeather.

While there are the expected local users from around the county (SLO, Paso, Arroyo Grande, etc), we also get visitors from places like Fresno, Mountain View, Sacramento, Seattle, Phoenix, Salmon ID, and Orlando.

We’re baaack…

Something happened with DNS Friday morning, and the SLOWeather blog was unavailable. It’s back now. Sorry for the inconvenience.

Google Earth vs real life

Tuesday, July 19th, 2005

Sunday Katie and I hiked to the top of Bishop Peak. Below is one of the pictures I took of Cerro San Luis from the peak.

Here is a Google Earth 3D image from the same perspective. Pretty close and pretty cool…

SLOWeather neighborhood

Google Earth doesn’t know about clouds in an aerial image, so it projects them on top of the mountains like snow.
