A powerful storm moved into California on the 13th and slowly advanced east into northern New Mexico on the 15th.  While it did weaken as it headed east, it still carried quite a punch as high winds were reported over much the state, but especially from the north and central mountains eastward to the Texas border where these regions saw an extended period of  35 to 45 mph sustained winds or gusts of 60 to 70 mph. Downslope winds on the east side of the Sangre de Cristo Mountains were particularly strong from near Angel Fire south to near Las Vegas. Cooperative observers near Gascon reported some the worst winds they had ever experienced with some 5000 to 8000 trees uprooted over an area of western Mora County. While some trees toppled because the ground was soft from snow melt, many were reported as twisted and snapped off 10 to 20 feet above ground with no discrimination between pine, fir, spruce or aspen. Falling trees damaged grazing allotment cross fencing in numerous places.
