I think this is the only type of spot you can do at this point - along with any kind of community relief efforts. Any type of promo drum beating/"We warned you first/First on the scene/the only station with..." is just insensitive. TV stations are there to serve the community... forget rating points and building your weather image right now. I think being there to document the events and providing a service to your community is the only way to go.

My heart goes out to the people of this area. Judging by this video -- they've been through hell.
