Thanks for making these available, it's a huge improvement over just dumping the raw text to the page. I've noticed though that I get the following errors in my web servers error log each time the page is accessed, when no storms are being tracked.
[error] PHP Notice: Undefined offset: 0 in /htdocs/Weather/NexStorm/tracreport2a.php on line 17

It looks like the bounds of those arrays should be tested after the file is parsed to see if they actually contain anything.
