storm surge is going to be a very real concern. if people are told to evacuate, they need to evacuate. there is a lot of very warm waters for this storm to strengthen, and with that, a lot of water likely pushed onshore. flooding at the coast will be life-threatening as well as some of the heavy rain inland could also pose an issue. norah. >> chris, thank you. we want to turn now to that horrific crash of a rescue helicopter caught on camera in florida. two people, including a firefighter, were killed when the chopper slammed into an apartment building. we get the latest now from joan murray of our cbs miami station. >> reporter: cell phone video captured the terrifying moments a broward sheriff's office fire rescue helicopter with its tail on fire spun desperately out of control. >> holy -- it's crashing! >> reporter: the doomed aircraft crashed into a pompano beach apartment complex and burst into flames. >> on top of the roof was all fire, a big ball of fire.
