The lightning storms that passed over central and eastern Oregon this week brought 5000 lightning strikes.  Firefighters will be watching to see whether those turn into larger fires. 

Carol Connelly, with the Northwest Coordination Center, says they're concerned about this weekend's weather, which is predicted to be hot and windy. Those winds could quickly turn a small, smoldering fire into an inferno. 

Fires that are started by lightning strikes can smolder for days, even weeks, before turning into a larger fire.
