Large fires near San Francisco or Caborca in NW Sonora (Mexico) are producing moderately dense smoke plume that are moving south and extend to near the northern portion of Isla Tiburon. The plume is about 50km wide. SW Texas/N Mexico: With a cyclone developing in the Texas panhandle, strong Swly flow is pulling sand and dust from the dry areas of NE Chihuahua, N Coahuila and the western panhandle of TX. The sand and dust is thin in density except for isolated moderate sand plume that originate from dry lake beds or sandy deserts such as Laguna de Cuervo north of Chihuahua (city). The most prominent area extends from the Chihuahua/Texas boarder across west Texas, over Midland/Odessa to the southern Cap Rock of TX. A cold front is dropping south across N Chihuahua and western Texas since night fall... so sand/dust plumes will orient more E-W across W and S Texas. Gallina
