If you’re using a regular over-the-air-type radio, and you’re within 750 miles or so of New Orleans, tune in 870am to hear WWL. It’s one of the original (literal) clear channel stations. In the old days you’d get them from coast to coast at night, but in recent years the FCC has chosen to allow new stations to clutter the AM band at night (when signals skip off the ionosphere). But still, worth a check if you’re within range. WWL also has a hurricane coverage network of other stations in the area.
If you’re listening over the Net, your station choices are WWL and WIST. Here’s a link to a browser thingie that plays WWL (using Windows Media or Silverlight). Here’s WIST’s audio page. Wish either used .mp3, but this isn’t the right time to complain. Both have excellent local coverage right now, from what I can gather. Lots of listener call-in stuff.
Can’t get Technorati to chart less than 90 days, but this chart shows Gustav action.
I’ll add more as the night goes on.
