Chaff Streaks in Northern Mexico

The KEMX (Tucson) radar composite image this evening indicates a couple of thunderstorms out in far eastern Arizona and New Mexico. The streamer-like echoes along the border and in northern Mexico are not weather echoes. Rather, they are indeed long streamers of chaff being advected southeastward, by the strong winds aloft, from the USAF training ranges near Ajo. These chaff plumes are extending far into Mexico. The radar's automated rainfall alogrithm has interpreted these as areas of rainfall and has accumulated light swaths of precipitation along the swaths. So it goes - user beware.
