Blistering heat stokes wildfires – Rob Marciano on the rarity of a 'fire weather watch' and how officials are responding

Many families are dealing with the agony of losing their homes this morning as the west coast wildfires continue to rage. Dozens of large fires are burning in 13 states west of the Mississippi River, with most of them in California, Nevada and Idaho.

In western Washington State, there's a new concern: Lightning. Much of the region is now under a rare 'fire weather watch.' Still, fire commanders there are cautiously optimistic. They declared the Taylor Bridge Fire 33% contained last night. They hope to have the 22,000 acre fire completely contained by Sunday.

Meteorologist Rob Marciano explains on "Early Start" this morning what a fire weather watch is, whether relief will come any time soon and what emergency officials are doing to minimize the risk.
