Sketchy information via emergency radio.  MGTT resident reported fire engines heading east on 94 toward the Border Checkpoint.  Radio traffic mentions using Otay Truck Trail as an access point.
Lyons Peak Camera (South) shows plume east of Otay Mtn.  I can’t tell if that is the Mexico fire, or another one.  http://hpwren.ucsd.edu/anim-a2/hpwren-iqeye14/hpwren-iqeye14.jpg
Will keep looking for info.  Attached photo from Lyons Peak.
This just in from IPN:
Mexico fire has crossed into the US, about two acres, air attack underway. Holding at two acres; slow rate of spread.
