Here’s a post we just put up that offers a brief overview to a directory where you can listen live to first responders (police, fire, ems). The directory is free to use and the streams are free to access.
Of course, not every county or city has a feed but, for the most part the I-95 corridor is well represented.
Also, the directory is always online (not just a storm resource) and is national in scope. From the Juneau Police Dept. to the Pinellas County Fire and EMS and many other locations.
A second post points out the fact that the FEMA National Situation Daily update is available online (can also be of use after the event) as well as a number of mobile tools from the National Hurricane Center including an option to be alerted to new updates via email or text.
You can always listen live to most major airport towers and centers in the U.S., Canada, and elsewhere.
