A flash flood warning was sent across L.A. County through the emergency alert system at about 4 p.m. — but the warning was only meant for the Fish Fire burn scar area in Duarte, according to the National Weather Service's John Dumas.

What happened? The mass alert seems to have been a tech issue. "There was some problem with our hardware system," Dumas said. "The box we drew is not the warning that went out."

So where is the actual area? NWS tweeted out map of the area Dumas referred to. The warning is in place until 4:45 p.m.
