The Orlando/Daytona Beach market used to have weather on digital substations of two local channels (one used to be NBC's Weather Plus), but these have since both closed down (one is now MeTV and the other is something in Spanish). There is no AccuWeather Channel or Weather Nation here. No WeatherScan, either.
All that we do have as an alternative to The Weather Channel is "Travel Weather Now" operated by the cable company, and the presence of this station adds a lot of pressure towards not adopting a 24-hour weather network in the area. It was recently revamped to actually cover local weather throughout Florida (mostly forecasts, satellite, and radar - no current conditions or, bizarrely, no active weather advisories) with some additional information for travelers. Previously, it was only for travel weather throughout the U.S. and the world with virtually no local weather information.
I think this is very foolhardy, since central Florida has some very active weather, especially during the spring and summer. This isn't Tornado Alley, but it comes in a close second during certain times of the year. At least all of the local broadcast stations will break into regular programming (whenever possible) with meteorologists in front of maps whenever there's a tornado warning in the area.
Otherwise, though, the only realistic ways to get weather on demand are to go online or to listen to the NOAA Weather Radio, which, surprisingly, virtually no one I know down here has. I have one in every room.
