Here's a sampling of live media coverage of Hurricane Ike available on the Web.
TV & VIDEO
KTRK ABC 13 - live video
KHOU - Hurricane page. Also has live video feed, but I couldn't get it to work.
CNN - has 4 live streams that rotate. Stream 2, for example, was broadcasting from Galveston's sea wall earlier. Governor Perry is on there right now.
KUHF - Houston NPR affiliate. Choose the news stream. The homepage also has hurricane information updates.
KTSU - Also a Houston public radio station. Looks like Jazz programming, but currently streaming news.
KIKK - CBS Radio Houston, and affiliated with CNN. It sounds like this is one of several affiliated station carrying a single stream at this point.
