Rescuers at demolished Surfside condo battle strong winds at Tropical Storm ...

Rescuers have been searching through fresh piles of rubble after the last of the collapsed Florida condo building was demolished but the crews have faced a new challenge from thunderstorms and strong winds which have now hit the area as Tropical Storm Elsa approaches.

The National Weather Service said there is a slight risk of severe thunderstorms across portions of South Florida on Tuesday 'due to an elevated tornado threat' associated with the storm.  

A video tweeted by Miami-Dade Fire Rescue shows workers battling strong winds even whilst standing on top of the debris of what was  Champlain Towers South building in Surfside.
