12/1500Z - and we (Hurlburt Field) are now at HURCON 3 as of 1300L. See that big 'X' right under the 36 hour position? That's my apartment. Of course, it never amounted to anything...but the pic is still amusing.

TS Helene (Sep 2000)

Images of Tropical Storm Helene. The filenames indicate the time/date and any additional info plotted (e.g., probabilities, etc.). Most of these sample_screens are of JStrack running on a Windows NT system, btw....

Pics from JStrack beta 1.14

The following are screen snapshots, taken with xwd (and converted to GIF), using JStrack beta 1.14.

Tropical Storm Erika, as of the 4 PM CDT advisory on 4 Sep 1997.
- TS Erika (19.8 kB GIF)
- TS Erika with 72 hour probs plotted (21.6 kB GIF)
Hurricane/Tropical Storm Danny
- As of 19/2100Z - Danny is forecast to come within 60 nm of my location (20.5 kB GIF)
- As of 20/0900Z - Danny is currently within 60 nm of my location (20.3 kB GIF)
- Complete Track (21.1 kB GIF)

By the way, the red 'X' in NW Florida is where I'm located. The blue background in the top bar (for ERIKA) indicates that the storm is not currently within 60 nautical miles of my location, nor is it forecast to be within the forecast period. The images from Danny show more clearly how this is used.

The red arrow at the bottom right of the screen (TS Erika) indicates that that particular storm position is actually off the chart.

Also, if you see a background color other than gray in the borders for the window (the chart itself is black/white), your browser is changing the colors in the image file. If anyone knows how, in HTML, to tell it not to do this, please let me know....

A Bit of Ancient History...

The following snapshots are from very old versions of JStrack, showing Hurricane Lili and/or Hurricane Josephine (both 1996 storms).

Lili/Josephine w/ legend (13.2 kB GIF) JStrack beta 1.1
Lili/Josephine w/o legend (15.1 kB GIF) JStrack beta 1.0
Lili (11.9 kB GIF) JStrack at (roughly) ONE WEEK OLD (25 Feb 97)!
By the way, what you see here is basically all it could do at the time....

In these versions of JStrack, the background for everything is gray, btw.
